Letting the inner ends of the gangs touch and roll together on large iron washers or bumpers at all angles to which they are set, neutralizes this force, reducing it to nothing. No end thrust of the gangs is carried by the Ijearings or the frame. Bumper Frame Without Joints The inner ends of the gangs roll together without the necessity of joints in the frame, as other makes of bumper type harrows require. Joints weaken the frame and sooner or later become loose from wear. Gangs of the Osborne bumper disk harrow are kept in rolling contact at all angles by pivoting the frame a ALL END r w ir/\ \ M " little behind the outer bearings.

The frame is of one piece of angle steel stiffened by a cross beam of the same material, and two angle steel pole bars which form the stub pole for attaching either a forecarriage or a stiff tongue. This makes a rigid frame which will hold the gangs to do thorough work in hard ground. The gangs are strongly braced to the frame and the set-lever bars. These braces form a rigid, triangular construction. An adjustable steel foot-rest, clamped to the pole liars, makes comfortable riding for any size driver. An easy seat with reinforced seat spring is attached where the driver will properly balance the harrow. Gangs are braced to the main frame and to the set-lever bars Strong Gangs The foundation of the gangs is a heavy, square arbor bolt. The spacing spools and the disks have square holes so that, should the nut become loose, they could not turn on the bolt and cut it. The nut is turned down very tight and locked in place. Each spool has a large flange on the end fitting against the convex face of the disk to give it support. The scraper burs and weight boxes are supported at the top of the bearing standards on bars of angle steel. This construction makes a solid gang that will withstand work in the hardest ground.

The bearing casmg is shaped to hold the octagonal wood bushings in place. The view shows the gang pivoted behind the bearing to keep the bumpers rollmg together cated with the leiist attention. Turning down the cups, grease will thoroughly lubricate the bearings. The grease enters in the middle of the bearing and is forced around the spool, inside of the wood bushing. Grease cups may be turned down by hand, or, if necessary, with a wrench furnished for the purpose. The driver need not stand in front of the harrow to turn down the grease cups. It is not necessary to carry an oil can. Hard oil is the most satisfactory luljricant for the bumper type of bearing. Disk Blades It is desirable to give the disk blades as much curvature as possible so they will pulverize the ground as it is laid in the little furrows. This curva- ture is definitely limited, however. The gangs are worked most of the time at an angle of about seven Bearings Since the bearings of the Osborne bumper disk harrow do not receive any end thrust, they need be built to with- stand only the draft from straight ahead. Each bearing has two octagonal wood bushings which are oil soaked before being put into place. Wear comes on the rear of the upper wood bushing. When this surface is worn, the upper bushing may be turned, giving a second wearing surface. Later, the lower bushing may be exchanged with the upper, furnishing two additional good wearing surfaces. When worn out, these bushings are easily and inex- pensively renewed. The bearing case is shaped to prevent the bushings from turning on the bearing spool and also to keep dirt from entering the bearing. The design of this bearing is well suited to its purpose and will wear for a sur- prisingly long time. Bearing Oilers The bearings are fitted with hard oilers. These keep the bearings lubri- as required, and keeping them filled with Grease cups may be turned down by hand when standing behind the harrow PAGE FOUR ^JK 06D0KXE>^ SQUARE HOLE The square arbor bolt, the flanged spool, and nut lock of the Osborne bumper gang teen degrees. When set at this angle, the front cutting edge of the blade should be pointed parallel with the line of draft, and the convex face of the disk should not extend beyond where the edge will cut. If it does, the disk will ride on the curved face without penetrating the ground easily. Osborne disk harrow blades are curved to pulverize as much as possible, yet penetrate hard ground easily. This is one secret of their good work. Set-Lever Bars The lower ends of the set levers move in a cixrve as the angle of the gangs is changed. With straight set-lever bars this would put the gangs out of level. Therefore, the set-lever bars on the Osborne bumper disk harrow are bowed up where the.y slide under the snubbing block to keep the gangs level at all angles. The snubbing block is adjustable and holds the inner ends of the gangs down to their work. By it the gangs may be leveled at an.y time. It is essential that the gangs work level to cultivate the ground to an even depth the full length of the harrow. Scrapers The scrapers are assembled with clips along a square scraper bar. Ai'-steei scraper unassem- * . . bled, showing how it is which operates the scrapei's in unison wlien the driver presses down the attached to the square scraper foot lever. The scrapers move from the middle to the outer edge of the disks, and clean them thoroughly. Pressure against the disks is regulated by a tension spring, and may be changed without tools. Scrapers can be adjusted singly or together. They are made of a special high grade of steel, and are beaded or grooved in the upper part to strengthen them. Transports The Osborne Ijumper disk harrow transports are simply constructed and very quickly attached. No tools are necessary. The.y are made of bar steel with wheels of good size, equipped with hard oilers. These transports will prevent damage to the disks in going to and from fields, and avoid cutting up the meadows or roadways. They also hold the blades off the ground when the harrow Osborne bumper disk harrow transport, is storcd in the tool-housc.

PAGE FIVE OSDORXE^ Osborne Rival Disk Harrow Long Levers Operate Easily Easy Riding Seat Scraper Foot Lever Adjustable All Steel Scrapers Heiglit of Stub Pole Adjustable on Forecarriage Adjustable Steel Clevis Hitch Osborne Rival disk harrow with forecarriage The biggest features uf this disk harrow are the great strength of the frame and the long- wearing qualities of the bearings. One piece of heavy bar steel forms the draw frame of the Osborne Rival disk harrow. This is stiffened by a cross sill and two pole bars of angle steel. The triangular construction of the J b_ cf . frame gives it rigidity the equal of one solid piece. The frames of the large sizes are reinforced to give additional strength where required. The gangs are attached to the ends of the frame at the cross sill by heavy "eye"' bolts which pass through the l)eai-ing standards. A Ijrace from the frame at the cross sill extends to the top of the gang, foraiing a triangular connection, which adds to the rig- idity of the harrow. Another brace frt)m the top of the gang frame attaches to the set-lever bars. This construction can best be understood by a glance at the above illustration. The Osborne Rival main frame is triangular in shape to withstand any excessive strain that may come upon it when harrowing PAGE SIX 06D0KXE>^ Gangs Can Be Set at Different Angles A particular advantage of this harrow is that the gangs can be set at diii'erent angles for side-hill work. The bearings are con- structed to take the end thrust of the gangs, allowing them to act independently. When di.sking along a hillside the lower gang may be set at a greater angle and will hold the harrow to follow the line of draft. Strong Gang Construction The Osborne Rival gangs are built for heavy work. They are strong, rigid and powerful. The gang frame is a strong piece of angle steel to which the scrapers and l^ear- ing standards are solidly bolted. The large steel arbor bolt upon which the disks and bearings are assembled is square. The disks and si)Ools have square holes. Thus there is no danger of the spools or the disks turning on the bolt. When the gang is assemljled, a large nut on the outer end of the arljoi- bolt is drawn up very tight and fastened with a positive lock which prevents it ever working loose. The spools are made with large flanges, which rest against the sides of the disks, giving them added strength. The gangs may be set at different angles for disking on side hills Osborne Rival disk harrow preparing plowing, which is covered with weeds, for the grain drill Note the good work of the center tooth PAGE SEVEN (^ OSDOKXf^- A-. Strong gangs and steel scraper equipment on the Osborne Rival disk harrow Set-Lever Bars Bow Up While the gangs may be working at different angles, they are always kept level by the bow in the set-lever bars. This bow offsets the curve described by the lower ends of the set levers when changing the angle of the gangs. It is placed where the set-lever bars slide under the adjustable snubbing block. Should the gangs get out of level, they can be quickly leveled by raising or lowering the snubbing block. The gangs should always be level to fill depressions and to cultivate to an even depth on level ground. The set-lever bars are always held against the snubbing block by resistance of the ground agains*^ the out- throw action of the disks. Durable Bearings The bearings of the Osborne Rival disk harrow take care of all end thrust of the gangs. This is done by a high ring around the middle of the bearing spool wliich turns in a groove in the bearing standard. The spool is made of special hard iron which practically can not be worn out. The face of the bearing is chilled and gives The curved set-lever bars keep the gangs level at all times ^ wearing surfacc like tho insidc of an en- gine Cylinder. Thebear- ings are large to insure light draft. The bearing stand- ards are strong and car- ry the grease cups which force the grease into the bearings at the upper rear part of the grooves where the greatest wear mustcome. These grease cups may be turned down by hand, or with a wrench furnished for the purpose. Dust caps prevent dirt from entering the bearings and cutting them out.

Tiiis ridge is torn up by the center tooth regularly supplied with the Osborne Rival disk harrow. Its good work is shown in the scene on page 7. This tooth is similar to that of a spring-tooth harrow. A small lever and quadrant permit changing the depth of cultivation and raising the tooth when going to or from fields. The Osborne Rival disk harrow leaves a smooth field with every part cT5lti- vated thoroughly even when disking but once over. Scrapers Adjustable all-steel scrapers of the rocking type clean the disks from the middle out hy pressing down on the scraper foot lever. Pressure against the disk blades is changed by the scraper tension si)ring without the use of tools. Scrapers are shaped to fit the square scraper bar and have a bead extending down the upper part to strengthen them. Disks It has taken many years of experimenting in the field with different shapes and curvatures The center tooth can be set at any depth desired The scraper tension spring can be changed without using any tools of disks to determine the exact used on Osborne disk harrows shape that would do the best work. This is the disk and is a well balanced combination of a disk flat enough to penetrate the ground and one curved sufficiently to do good pulverizing. The blades are made of a special quality of steel which will retain a good edge. They are ground and polished, insuring that they will clean well. By Transports equipping the Osborne Rival disk harrow Osborne Rival transport. The wheel is large and equipped with a grease cup with transports, the blades are not damaged b.y sticks and stones in the road, nor is the road bed torn up by the harrow in passing ^;to and from fields. These transports are inserted-' in the frame and the harrow drawn forward until the transport clamp fits around the bearing. The wheels are large in diameter and roll easily over the ground. Hard oilers lubricate the bearings. Transports are not regular equipment, but will be furnished on special order. PAGE NINE 06D0RXf>- Two LEVERS AT CUTTING CUTAWAY ATTACHI Osborne Rival disk harrow equipped with forecarriage and cutaway gangs with scrapers Cutaway Gangs for Osborne Disk Harrows Cutaway gangs for Osborne bumper and Kival disk harrows will be furnished when ordered. Cutaway disks are especially adapted to working- in light, loose soil, because they do not cut so deep nor pulverize so finely as the solid disks. The cutaway gangs will make the harrow draw easier, because it does not cut with a continuous edge and there is less disk blade to be forced into the ground. Scrapers for cutaway gangs will also be furnished. Tandem Attachment for Osborne Disk Harrows Instead of "lapping half"' and traveling over the same ground twice, the Osborne bumper or Riv- al disk harrow will prepare the seed bed in half the time when equipped with cut- away tandem attachment. The gangs are set for in- throw, filling the furrows made by the disks on the frontgangs. As the tandem attachment is always work- ing on freshly harrowed ground, the disk blades are cutaway to prevent them from wallowing l\v cutting too deep.

These bearings are fitted with hard oilers which keep the wearing surface well lubricated. As the gangs are forced in opposite directions, a frame of heavy bar steel, braced with strap iron, is adopted. The gangs are pivoted at the corners of the triangular frame and are set at independ- ent cutting angles by two levers convenient from the driver's seat. The resistance of the soil against the disks tends to throw the outer ends of the gangs up. They are held down by two loops of strap iron sliding along a brace near the center of the frame. The tandem attachment is connected to the front harrow in a moment's time. Scrapers for cutaway gangs will be supplied as special equipment at extra cost. -^^r An Osborne disk harrow with tandem attachment prepares a mellow seed bed with driving but once over the field PAGE ELEVEN (^O^DORXE^ ^" -~i Osborne Orchard Disk Harrow POWERFUL. CONVENIENT LEVERS -^ SERRATED GRIPS HOLD FAST NE NOTCHES FOR CLOSE ADJUSTMENT RIGID SET LEVER BARS ^ Osborne orchard disk harrow with gangs set for out-throw, as used for regular disking Orchards require the use of a disk harrow specially designed for orchard cultivation. Horses cannot be driven very close to trees and vines, but it is necessary that the ground be stirred under the branches. The Osborne orchard disk harrow is built with a low, wide frame of bar steel, especially braced to make it rigid. It will pass under very low branches without doing damage. With the regular frame the width of cut may be extended to six feet, but l>y means of the extension frame an extreme width of cloven feet six inches can be reached. This extension frame is attached in a short time and permits of cultivating close to the trunks of trees without damage to the branches. The Osborne orcliard disk harrow will do the finest kind of work in keeping the orchard free of grass and weeds. Gang Adjustments The gangs may be set for in-throw oi- out-throw. Either the inner or outer ends of the gangs may be tilted up for making i-idgcs or ditches, or cultivating shallow close to the trees and deeper farther away. The gangs may be set close together and ar- ranged for out-throw. Then it will do the same work as a regular disk Osborne orchard disk harrow with extension frame and frame shields works ■ close to the trees without damaging the fruit or branches DarrOW. PAGE TWELVE ,-^ 06D0RXE^ Gang Bearings The gangs are given ample bearing surface. These bear- ings are fitted with oil-soaked hard maple bushings which will last a long time if prop- erly lubricated. The grease cup places the hard oil at the center of the bearing where it is well disti-ilnited over the wearing suii'ace. The wood bushings are inexpensive to renew when finally worn out.

The quad- rants have fine notches for close adjustment. Each gang is regularly equipped with a shield to avoid damaging low-hanging fruit and branches. When etpiipited with the extension frame, it is advisal)le to use frame shields also, which are sup- plied on special order only. Forecarriage The regular Osborne disk harrow forecarriage is sup- plied with the Osborne or- chard disk harrow. It carries the neck weiglit and keeps the harrow running steadily and in line.

The pole may be set in the middle for 2 to risht 5 horses Osborne Disk Harrow Forecarriage Nearly all fields are so rough as to cause the disk harrow to draw unsteadily and the tongue to whiji and worry the horses, giving them sore shoulders during early spring work. It is to free the horses of this action of a stiff tongue and varying draft of the disk harrow that this forecarriage is being pur- chased with nearly all Osborne disk harrows sold, or for those already in field use. It keeps the harrow running smoothly and in line, and makes it easier to °;; 'jpf';'"'4"-3 work into corners and close to fences. The forecarriage is used with or without a pole. A pole is essen- tial only in very hilly sections of the country when driving to or from fields. It is regularly equipped with pole plates for two horses when a tongue is ordered. Set-over irons for three or five horses are special pole equipment. These set-over irons make it possible to use the pole with any number of horses desired. The wheels of the fore- carriage turn completely under the stub tongue in making a short turn. It is not intended that the forecarriage should interfere with the direct line of draft from the horses' tugs to the gang connection. It should be adjusted to carry the weight of the front end of the harrow and press on the ground just enough to keep the harrow working in line without adding to the draft of the implement. To produce this result the stub tongue and draft connection are adjustable to several heights on the vertical shaft. The steel clevis also has a range of up-and-down adjustment. Thus the Osborne forecarriage is suited to use with any size team and various types of disk harrows. The clevis is so attached as to hold the whifHetrees off the ground and the horses' heels. The vertical shaft is pivoted in the fore- carriage axle, giving limited swivel action when disking uneven ground. The stub axles are cast in the hubs with the spokes, making them as one piece with the steel wheels. They are inserted in the bearings and keyed with take-up washers near the middle of the axle. This permits the wheels to act independently and produce flexibility when working rough fields. The take-up washers provide for making the axles tight when they have become worn. The grease cups force grease into the axle bearings where it will be distributed thoroughly. Dust caps exclude dirt and pre- vent the axles from cutting out.

The peg-tooth harrow is the most efficient implement for breaking the lumps turned ui) Ijy the disk harrow. To properly do the woi'k of smoothing, the harrow sections should l>e stiff so tliat vigdious action is given when passing over irregularities on the surface. The Osborne peg-tooth harrow is l)uiit with the intention that every tooth sliall be held to do a thorough job of harrowing. The tooth bars are of channel steel. They cannot twist out of shape, nor will they check or crack like wood bars and let the teeth become loose. The rigidity of a section of the Osborne peg-tooth harrow is due to two stiffening bars placed near the ends of the section which liold the tooth bars from acting indepen- dently. This feature meets the approval of every farmer who sees it. Through these stiffening bars any strain that would have come on one tooth bar when a tooth struck a hard spot or obstruction, is distributed to all of the tooth bars in the section. Thus, any bending force that may come on a tooth bar cannot twist the bar out of shape. Each tooth fits into notches in tlie edges of the tooth bar and is clamped in place by a clip, shaped to fit closely about the tooth, and drawn up light with two nuts. The teeth cannot work loose. The heads of the teeth are upset to further insure against their becoming lost. Either J^-inch square or fs-inch diamond-shaped teeth can be furnished. Each section is equii)ped with foui- runner teeth for transporting the harrow to and from fields, without wearing down the tooth points on macadam roads or loading the harrow into a wagon. The '^ '■•"''°" ^t^nTatuchren, *""""" ""^ PAGE FIFTEEN (WOSDORXE^ runner teeth do the same work as other teeth when set for harrowing. The draw bar is attached to the sections in such a way that it will not unhook when turn- ing corners. The draw bail is made up of heavy jointed rods and chain, furnishing a substantial draft connection. Slip Notch Lever Quadrant Each section has a long lever for changing the slant of the teeth. The quadrant has slip notches so that it is only necessary to pull back on the lever, without lifting the hand latch, when setting the teeth to do harrowing. The first notch is deep and locks the lever for transporting on the the runner teeth. i The slip ratchet makes it easy to increase the slant of the teeth Sizes Orchard Guards When using a peg- tooth harrow in an orchard, there is always No. of sections- - o O *> 3 3 .> 4 4 4 Teeth per section 25 30 35 25 30 35 25 30 35 Ilarrowintr widtli 8' .3" 9' 11" irs" 12' 5" 15' 17' ti" 16' 8" 20' 23' 5" Orchard guards protect the trees from damage and prevent trash catching on the ends of the tooth bars.

Orchard guards for the Osborne peg-tooth harrow make this a safe implement to use in the orchard. They are easily bolted to the tooth bars. Orchard guards are special equip- ment and cost extra. Riding Attachment The tediousness of plodding all day behind a peg-tooth harrow is avoided by fastening a riding attachment to the draw bar wiiii only two bolts. The large steel wheels make easy riding and add little to the draft. The attachment is practically all steel. The wheels are lubricated by hard oilers and swiveled to turn and follow the rear of the har- row around corners. The cost of this attachment is slight. This view shows why the teeth never work loose Osborne peg-tooth harrow riding attachment which is constructed .timost entirely of steel.

I'Qll^'^- Osborne Spring -Tooth larrow Osborne spring-tooth harrow A tillage tool with lively lifting action; the best implement for stony or cloddy ground; a weed killer; destroyer of volunteer wheat and fine for thinning winter wheat; a first-class alfalfa cultivator and a preparer of good seed beds. The Osborne spring-tooth harrow is built up of an angle steel frame with steel pipe tooth bars attached to the frame by malleable castings. The front of the frame is given an upward slope to allow it to pass over trash and clods. To the bottom of the frame is bolted a removable steel runner to protect it from wear. This can be renewed at any time should it become worn out. A portion of the frame of the left-hand section is cut out and a steel bar extended over the top at this point to permit trash clearance from the middle of the harrow, and to make the frame rigid. The sections are hinged together to give flexible action on rough ground, assuring that all of it will be cultivated. The hitch is so placed, with holes for adjusting the line of draft, that any desired action of the harrow is possible. The levers are long, making it easy and convenient to change the cutting depth. The quadrants have fine notches for close adjustment. The teeth are made of oil-tempered steel with sufficient length and resiliency to produce a lively action in the soil. They are held to perform their work by the rigid steel frame and will give excellent results in very hard ground. A feature which aids in working hard ground is the spanner grip by which the teeth are attached to the tooth bars. You will notice this grip in the illustration above. The spanner grip puts the twisting strain on the pipe bar rather than on the tooth and the tooth bolt. A slot in each tooth permits setting the teeth to penetrate to a lesser or greater depth than with the usual changes by the levers. Special, reversible, double-pointed teeth can be supplied, which practically doubles the use- fulness^ of one set of teeth. These are furnished at a slight additional cost. PAGE SEVENTEEN 06D0KXE>- /^ Osborne Sulky Spring-Tooth Harrow t Osborne sulky spring-tooth harrow This is the Osborne spring-tooth harrow with riding attachment, and the levers and quadrants })hiced nearer the front where they may be easily reached from the driver's seat. This attach- ment may be purchased with the harrow, or can be added at any time. The sulky attachment is liuilt in two sizes — one size for the 1.5-tooth harrow, and another for the 17 or 23-tooth harrows. If ordering a sulky attachment for a harrow you already have, be careful to state which size your harrow is. The weight of the driver may be carried by the sulky attachment on soft ground, or thrown on to the teeth in hard ground. The wheels are within the harrow and do not travel on the cultivated ground. The runner shoes in front assist in maintaining an even depth of cultivation and make it easy to t,i-ansport the harrow to and from fields. Osborne sulky spring-tooth harrow freeins fall plowing of weeds and volunteer wheat PAGE EIGHTEEN 06E)0KXE^ Osborne Combination Harrow Osborne combination harrow The Osborne combination harrow does the same effective work as a i-egular spring-tooth harrow. It lifts clods to the surface and lets the finer compact soil fall below where it makes a first-class seed bed. After the clods are lifted to the surface hy the resilient action of the spring teeth, the row of trailing teeth in the rear breaks up the lumps while they are fresh and leaves a smooth surface without using a peg-tooth harrow. This puts the ground in good condition for the drill. The Osborne combination harrow is built with a fi-ame of one piece channel steel to each section, and tooth Ijars are of the same material. The frame is raised high to give ready clear- ance to trash. The teeth are held to the tooth bars by a clip and two bolts which permit adjust- ing them to make up for wear at the points. Each section has a long lever and a quadrant with fine notches for close adjustment. Each trailing tooth is attached to the channel steel bar across the rear by a bolt and a clip which fits into the bar and holds the tooth secure. The slant of the teeth may be adjusted by using the different holes in the brace from the trailing-tooth bar to the frame. The trailing teeth are made of round steel with a head on one end to prevent their slipping through the clips and Ijecoming lost. Two runner shoes are swiveled with the adjustable hitch at the front corners of each section. These keep the harrow penetrating at an even depth and hold it to run steadily. The spring teeth can be raised high and the runner shoes and trailing teeth will carry the harrow. The Osborne combination harrow is furnished in two and three sections. Two sections culti- vate a width of ,5 feet, 6 inches, and 3 sections 8 feet, 5 inches. PAGE NINETEEN 06E)0KXE^ Osborne Vineyard Spring-Tooth Harrow This harrow is made up of one section of the regular Osborne spring-tooth harrow and fitted with a draw bail. It is especially adapted for use in vineyards, orchards, nurseries, and where a larger harrow is unnecessary. It is built in 7, 9 and Ti-tooth sizes and will be furnished with steel handles on special order. The 7-tooth harrow cuts 1 foot, 11 inches. The 9-tooth harrow cuts 2 feet, 6 inches. The 12-tooth harrow cuts 3 feet, 4 inches. Osborne vineyard spring-tooth harrow with steel handles CoUIngs Alfalfa Tooth The oval shape of the tooth permits it to scour readily and also stiffens it so that it penetrates hard ground The Osljorne spring-tooth harrow has been perfected as an alfalfa cultivator by fitting it with the Collings tooth for alfalfa cultivation. This tooth has the resiliency of the regular tooth, though it is stiffened by a crimp along the portion which penetrates the ground. While this holds the tooth to penetrate better, it also avoids damage to alfalfa plants by pre- senting a curved face against the crowns and will not tear them out. The point is oval- shaped and not liable to cut off many roots. The point and shank clear themselves of trash and scour clean. The Osliorne spring-tooth harrow, with Collings alfalfa teeth, loosens the ground without any tendency to pack it. Being in sections, it adjusts itself to uneven ground much better than a stiff frame cultivator. The Collings alfalfa teeth are furnished on special order. Be sure to ask for the correct number of teeth when ordering. PAGE TWENTY 06D0KXE^ ^ Osborne Cultivators Osborne cultivator No. 71. No. 51 is similar except that it has 5 shovels.
