 Conserving Moisture with the Disk Harrow 
 
 The disk harrow, properly used, will do more to increase the crop yield than any other farm implement 
 It lends itself to a variety of uses. When used directly after the binder, it forms a dirt mulch which protects 
 the moisture in the sub-soil from the evaporating heat of the sun. The farmer who takes this precaution to 
 preserve moisture is invariably repaid by the heavy crop he harvests the following year. 
 
 The use of the disk harrow immediately before the plow produces results that the farmer cannot afford to 
 neglect. A seed bed may to all appearances be in ideal condition to produce a large crop, while in reality it 
 is not even well enough prepared to return the cost of producing the crop. This condition of the soil is usually 
 found where the land is not disked before plowing. Sod or stubble ground will often break into large lumps 
 as it is turned to the bottom of the furrow. The lumps thus left form lartje air spaces which break up capillary 
 attraction and prevent the proper amount of moisture from reaching the plant roots. By using the disk harrow 
 before the plow, the stubble or sod is thoroughly broken up, so that when turned to the bottom of the furrow 
 it is in a mellow form which readily absorbs moisture and furnishes nourishment to the plant roots. Used at 
 the proper season, the disk harrow will effectively destroy obnoxious weeds — another manner in which moisture 
 is preserved for the use of the growing crop, 
 
 The results obtained by the use of the disk harrow depend largely upon the time that the disk is used. 
 The ground should be disked as soon as possible after it has taken in moisture. No time should be lost after 
 the soil is sufficiently dry for the disks to scour. The great advantage of disking when the soil is in this condi- 
 tion is that all the moisture is stored in the sub-soil for future use, and the surface is formed into a granular 
 mulch which will not blow away. Old ground can be disked while in this condition with the same satisfactory 
 results found when the disk harrow is used on sod.

 The McCormick disk harrow is one of the strongest harrows made. It has a reputation for doing the best 
 
 work under all conditions and standing up under the 
 work for years. The great strength of the main frame 
 arid the manner in which it is fastened to the bearings 
 account for the good work of this harrow and the depth 
 to which the gangs penetrate the ground. 
 
 The draw frame of the McCormick disk harrow is made 
 
 of one piece bar steel reinforced where the greatest strain 
 
 comes. The cross sill is angle steel. Two pole angles 
 
 made of steel are riveted solidly to the center of the 
 
 cross sill and draw frame, making the strongest and 
 
 at the same time the lightest frame known. 
 
 The steel angle bars take the place of the stub 
 pole when the regular pole is set to one side for 
 three or five horses. This gives great strength and 
 rigidity of the frame. The draw frame 
 is fastened to the bearing standard by 
 means of eye-bolts, which gives ab- 
 solute freedom of motion to the gangs. 
 As a result, the frame does not in any 
 manner interfere with the action of 
 the disk when set at cutting angles. 
 For this reason the McCormick disk 
 harrow penetrates the ground as deep 
 as the user desires.

 Strong Gang Frame 
 
 It is of just as much im- 
 portance to have a strong 
 gang frame as it is to have 
 a rigid main frame on the 
 disk harrow. The main 
 frame holds the gangs level, 
 but the good vi'ork of the 
 scrapers and disks depends 
 upon the strength of the 
 gang frame. The gang 
 frame of the McCormick disk 
 harrow is made of two angle 
 steel bars solidly fastened 
 together with steel bars at 
 the end. The bearing stand- 
 ards are solidly fastened to 
 the angle bars. This con- 
 struction holds the bearings 
 in a line with the axle, so 
 that there is no possible 
 chance for them to cut out 
 by twists and strains. 
 The spools between the disks are made with wide flanges, giving the disks extra support. The holes 
 in the disks and spools are square and fit the arbor bolt closely. It is utterly impossible for a disk to turn in 
 the arbor bolt even though it should become loose. The arbor bolt is fastened with a lock nut so that it will 
 not loosen. 
 
 A strong gang frame is necessary for good disking 
 
 Level Gangs 
 
 It is a well-known fact that a disk harrow will not do its best work unless the gangs are working level. 
 When a farmer disks, he wants to 
 level the ground as well as cultivate 
 it. If a harrow gang follows the 
 unevenness of the ground, the best 
 disking is not being done. 
 
 The gang on the McCormick disk 
 harrow can always be kept working 
 level, whether the harrow is new or 
 whether it has been used a long 
 time. An adjustable snubbing block 
 takes up any looseness or wear that 
 may take place, and the curved set 
 lever bars keep the gangs level at 
 whatever angle they may be set. 
 The curve in the lever bars is so 
 made that it takes care of the circu- 
 lar movement at the lower end of the 
 set levers. The accompanying illus- 
 tration shows that it is impossible for 
 the McCormick disk harrow to buckle 
 in the center when the snubbing 
 block is properly adjusted. 
 
 The gangs are kept working level by the adjustable snubbing block working against llie 
 
 bowed set levers

 Efficient for Work on Side Hills 
 
 Each gang on (he McCormick disk harrow 
 is controlled by a separate lever. These levers 
 are within convenient reach of the driver and 
 are easily operated. Much better work can 
 be done with the disk harrow when each gang 
 is operated by a separate lever. One of the 
 great advantages of the two-lever construction 
 on the McCormick harrow is its efficiency for 
 work on side hills. When working on very 
 steep side hills, there is always a tendency 
 for disk harrows to work down the hill. By 
 setting the gang on the lower side at a greater 
 angle than the one on the upper side, the 
 harrow will retain its natural position, which 
 is not possible unless the gangs can be set at 
 uneven angles. 
 
 If the gangs are set at different angles, 
 dead furrows can be filled or ridges removed 
 from the ground. 
 
 Center Tooth 
 
 It frequently happens that a farmer has 
 occasion to disk the ground but once. When 
 doing this with the ordinary disk harrow, 
 there is a ridge left between the gangs. The McCormick disk harrow is equipped with a center tooth, which 
 cultivates and levels this ridge between the gangs. Every portion of the ground is cultivated when the 
 McCormick disk harrow is used. By means of a lever and quadrant, the center tooth can be adjusted for deep 
 or shallow cultivation, or raised high from the ground when transporting the harrow. The lever and quadrant 
 for raising and lowering the center tooth is placed in front of the seat, within convenient reach of the driver. 
 
 The gangs can be set at different angles for side-hill cultivation 
 
 
 The center tooth on the McCormick disk harrow cultivates the ridge usually left between the gangs

 Scrapers 
 
 The scrapers used on the McCormick disk 
 harrow are of the steel rocking type. Each 
 scraper is independent of the other, and can 
 be removed or adjusted separately. When 
 in its regular position, the scraper is near the 
 center of the disk and does not rub. By 
 means of a foot lever, they can be moved 
 from the center toward the edge of the disk, 
 so that no matter what condition the soil is in, 
 the disks are always kept clean. The coil 
 spring attached to the scraper bar can be 
 adjusted to give any tension to the scraper 
 that the operator desires. The tension can be 
 changed instantly without the use of any tooL 
 
 The tension of the spring in the scraper bar can be changed insteuitly without 
 the use of any tools 
 
 Construction of the Disk 
 
 The disks for the McCormick disk harrow 
 are made of a high quality of steel, ground 
 and polished so that dirt does not adhere to 
 them. They are the right shape for good 
 work. They are flat enough to penetrate the 
 ground, and yet have sufficient curve to pul- 
 verize it thoroughly. Anyone can satisfy him- 
 self of this fact by watching the work of the 
 McCormick disk harrow in the field. 
 
 oizes 
 
 The McCormick disk harrow is furnished 
 with 8, 10, 12, 14, and 16 disks. The disks 
 are made 16, 18, and 20 inches in diameter. 
 When working in extremely hard ground, the 
 small disk is preferable ; in loose sandy soil, 
 the large disk will be found to give the best 
 satisfaction.

 Durable Bearings 
 
 The bearings used on the McCor- 
 mick disk harrow are the most dur- 
 able ever devised for this kind of 
 an implement. If kept well supplied 
 with oil they will never -wear out. 
 They are provided virith a large cen- 
 ter ring projection to relieve the 
 ends of the bearings of end thrust. 
 This eliminates extra draft and wear. 
 The bearings are chilled, have a 
 large wearing surface which makes 
 them very durable. Dust bands fit 
 over the ends of the bearings to 
 prevent dirt from falling in. These 
 bearings are as nearly dust proof as 
 it is possible to make them. No one 
 ever heard of the McCormick disk 
 harrow bearings vi^earing out if they 
 received the proper amount of oil at 
 all times.

 Easy to Oil 
 
 The oiling arrangement on the McCormick disk harrow is conveniently placed so that the operator 
 can oil the harrow v^^llen standing behind it. This eliminates the danger that comes from standing in front of 
 a harrow when horses are hitched to it. Another advantage of the convenient oiling arrangement is that 
 the more easily a man can get at his machine to oil it the better care and attention he will give it. The oil 
 pipes in the McCormick disk harrow are easily cleaned. These pipes are large, and oil flows into the large 
 
 groove which encircles the center of the bearing. This causes the oil 
 
 to be fed evenly to all parts of the bearing. This uniform film of lubri- 
 cant keeps the bearing from wearing and makes the McCormick disk 
 harrow an exceptionally easy running and long-wearing implement.

 McCormick Disk Harrow Forecarriage 
 
 A forecarriage will be furnished with any 
 McCormick disk harrow on special order at addi- 
 tional cost. It is of special use in working close to 
 fences, in preventing the tongue from lashing the 
 sides of the horses, and in keeping the harrow 
 running steadily. The bearings are fitted with hard 
 oilers. Dust cannot get into the bearings if suffi- 
 cient grease is used so that it oozes out at the collar. 
 The McCormick forecarriage can be used with 
 or without a pole. It requires only a few seconds 
 to change the pole from the center to one side, or 
 to remove it entirely. The pole can be set either 
 to the left or the right-hand side, enabling the farmer 
 to adjust the pole to his team. 
 
 The McCormick forecarriage can be raised or 
 lowered to five different positions. This makes it 
 possible to fit the forecarriage to any size team and 
 still have the line of draft such that the fore- 
 carriage wheels will just touch the ground. This keeps the 
 
 harrow working in a line without adding to the draft of the 
 
 implement. 
 
 The regular pole of the McCormick disk harrow is bored 
 
 to fit the forecarriage. It is only necessary to order the set-over 
 
 irons for use with 3 or 5 horses, or the pole plates when using 
 
 2 or 4 horses. This eliminates the necessity of buying an extra 
 
 pole for this attachment. When ordering a harrow with the 
 
 forecarriage, care should be taken to state whether the pole is McCormick forecarriage

 McCormick cutaway disk harrow with forecarriage 
 
 The principal dilTerence between the McCormick cutaway disk harrow and the regular disk harrow is that 
 the cutaway is equipped with cutaway disks and a special type of scraper. The work done by the cutaway is 
 very similar to that of a regular harrow, except that the cutaway stirs the ground in larger chunks and does not 
 pulverize it as finely as the regular harrow. The cutaway disk harrow is furnished in the same sizes as the 
 regular harrow. 
 
 Transport Trucks 
 
 Both the McCormick regular 
 and the McCormick cutaway 
 disk harrows can be equipped 
 with transport trucks. These 
 trucks are of particular value 
 when moving from one field to 
 another. It takes only a little 
 of the driver's time to apply or 
 remove them. They are fur- 
 nished on special order at a 
 slight additional cost.

 Tandem Attachment for McCormick 
 Disk Harrow 
 
 McCormick tandem 
 attachment 
 
 It is a well-known fact that the best results are secured with the disk harrow when the ground is double 
 disked or gone over twice in opposite directions. To do this with the ordinary disk harrow takes up a great 
 deal of time that is not always to be had at the planting season. 
 
 The McCormick double disk harrow consists of the regular McCormick disk harrow with an inthrow 
 cutaway harrow attached as a trailer. It is a practical machine for the man who wishes to double disk and 
 whose time to do so is limited. The action of the disks on the tandem attachment is just the reverse of 
 that on the regular harrow. As a result, the soil is well pulverized and a good seed bed is formed. 
 
 The taffdem attachment is equipped with the same bearings and conveniences for oiling which are used 
 on the regular McCormick disk harrow. It is equipped with a lever on each gang, so that the gangs can be set 
 at different angles for side-hill cultivating. The gangs are kept working level by means of steel straps in the 
 center. Steel scrapers keep the disks clean in all conditions of soil. These scrapers are furnished on special 
 order at slight additional cost. 
 
 The tandem attachment on the McCormick double disk harrow is made in 4, 5, 6, 7 and 8-foot sizes. 
 
 The McCormick disk harrow with the tandem attachment prepares a good seed bed in a short time

 McCormick Peg -Tooth Harrow 
 
 A peg-tooth harrow is subjected to a great many hard knocks. It is 
 often necessary to use it in rocky soil or where there are many tough 
 roots. This means that a harrow to do this work must withstand a great 
 many twisting strains. The ordinary peg-tooth harrow will not stand 
 this kind of work for any length of time. 
 
 The McCormick peg-tooth harrow is unusually strong for its weight. 
 This is due to two strengthening bars on each section, which make it 
 impossible for a tooth to catch on a stone or other obstruction and bend 
 the bar to which it is attached without bending every other bar in that 
 
 section. The tooth beams are U- 
 bars, thicker in the center than 
 at the edges — a construction 
 which makes them unusually light 
 and strong. 
 
 The tooth clips are forged 
 from steel and are fastened with 
 two nuts, making a very sub- 
 stantial fastening. The teeth have 
 up-set heads and are of steel, 
 tempered to give good cutting 
 edges. They can be furnished 
 /j-inch square or ^8-inch 
 diamond shaped. The diamond- 
 shaped tooth gives exceptionally 
 long wearing service and the 
 peculiar shape keeps the teeth 
 sharpened for easy draft. 
 
 The McCormick peg-tooth 
 harrow is furnished with 20, 25, 
 30, and 35 teeth to a 
 section. Each section is 
 attached to the drawbar, 
 making the harrow very 
 flexible. 
 
 A harrow equipped with this strengthen* 
 
 ing bar will not bend even under the 
 
 weight of a heavy man 
 
 This is what happens to a harrow not equip* 
 
 ped with strengthening bars when it 
 
 strikes an obstruction

 Slip Ratchet Easily Operated 
 
 The McCormick peg-tooth harrow is equipped with a shp ratchet with fine notches, which permit close 
 adjustment of the teeth. A slip ratchet is a great advantage when a number of sections are in use. The teeth 
 
 have a wide range of adjustment, 
 and are so placed on the harrow 
 that trailing is impossible. Each 
 tooth must do its full share of the 
 work. 
 
 The McCormick peg-tooth harrow 
 is equipped with a runner tooth at 
 each corner of the sections. This 
 makes it possible to transport the 
 harrow from one field to the other 
 without tearing up the ground.

 Orchard Guards 
 
 When harrowing among trees, vineyards, and where the outer ends of the tooth bars are apt to come in 
 contact with posts, vines, stumps, etc., the orchard guards serve as a protection. These orchard guards also 
 prevent trash from catching on the ends of the tooth bars. They are furnished only on special order at a slight 
 additional cost. 
 
 Riding Attachment 
 
 The McCormick riding attachment is composed of two long arms, which fasten to the drawbar of the 
 harrow, and an axle so made that the wheels turn in when turning corners. This enables the driver to make 
 short turns without the wheels sliding or tipping up. The wheels are made of steel with staggered spokes and 
 are high enough to keep the driver well out of the dust. They have wide tires so they will not pack the ground. 
 This attachment is always in line with the draft and does not disturb the good work of the harrow. It can be 
 furnished with any peg-tooth harrow at a slight additional cost.

 McCormick spring-tooth harrow. It is furnished with 
 15, 17, 23, or 25 teeth 
 
 Soil must be properly 
 aerated to bring out the 
 best plant growth. If air 
 does not circulate through 
 it readily, it becomes sour 
 and will not develop its 
 greatestsupplyof plantfood. 
 There is no implement that 
 so thoroughly airs the soil 
 as the spring-tooth harrow. 
 For this reason it 
 has an important 
 place in the prep- 
 aration of the seed 
 bed, and no farm 
 should be without 
 its use. In cold, 
 damp, backward 
 seasons, it is valu- 
 able for stirring 
 the ground so that 
 the sun and air 
 can warm the soil 
 foranearly seeding. 
 
 There are many 
 
 soil conditions in which the spring-tooth harrow should be used in connection with a disk harrow. It is efficient 
 in loosening up fine, tenacious soil, for killing weeds in the germinating period, and for many similar uses. 
 
 The McCormick spring-tooth harrow is constructed entirely of steel. The frame is bent upward in front 
 and the inside of each section of the frame is cut away, so that trash will not accumulate. The tooth beams 
 are high and the teeth have sufficient space between them for the trash to work its way through readily. The 
 teeth are spaced so that they do not trail. They are made of a high quality of spring steel and are fastened to 
 the tooth bars by adjustable clamps, permitting the teeth to be adjusted to compensate for wear. 
 
 Collings Teeth for Cultivating Alfalfa 
 
 Collings spring teeth can be furnished for use on the McCormick spring-tooth harrow at slightly greater cost 
 than the regular spring teeth. These teeth are placed on the McCormick harrow exactly the same as the regular 
 teeth, the only difference being the shape of the tooth point. 
 
 By purchasing a set of Collings teeth a farmer can have an alfalfa 
 cultivator and a regular spring-tooth harrow in one implement. 
 
 The advantage of the Collings tooth is that it is somewhat stiffer at 
 the point, and does not spring the full length of the tooth when working 
 in hard ground. 
 
 A harrow equipped with these teeth does practically the work of a 
 cultivator. At the same time the tooth has a different action in the 
 ground from a stiff-tooth cultivator. It has the advantage of a spring 
 in the tooth and is oval shaped, permitting it to pass the crown of the 
 alfalfa without doing it any harm. It wears to a sharp point and, being 
 
 oval, does not catch trash at the 
 end. This type of alfalfa cultivator 
 loosens the surface of the ground, 
 giving the alfalfa roots an abun- 
 dance of air. 
 
 Runner shoes protect frame from wear 
 
 The Collings tooth has the same 
 
 adjustable tooth fastening as the 
 
 regular tooth. As the tooth wears 
 
 it can be adjusted

 Close Adjustment of the Teeth 
 
 No farm should be without the use of a sprinR-tooth harrow 
 
 are fitted with detachable runner shoes. These shoes can be renewed when they 
 the McCormick harrow an exceptionally long wearing frame. 
 
 The adjustment of the 
 teeth on the McCormick 
 spring-tooth harrow is very 
 fine, so that the operator 
 can cultivate to any depth 
 he desires. The sections 
 are hinged together, per- 
 mitting them to follow un- 
 even ground. 
 
 The draft hook is adjust- 
 able, so that more or less 
 weight can be put on the 
 front or rear of the harrow, 
 as conditions require. It is 
 usually desirable, when 
 harrowing trashy ground, to 
 have the rear teeth deeper 
 than the front, and when 
 working in hard ground, to 
 have the front teeth working 
 deeper than the rear. Ad- 
 justments to bring about 
 these results can be quickly 
 made on the McCormick 
 spring-tooth harrow. 
 
 The bottoms of the frame 
 become worn. This gives , 
 
 McCormick Vineyard Spring-Tooth Harrow 
 
 The McCormick vineyard spring- 
 tooth harrow can be used for the 
 same purposes as the regular spring- 
 toolh harrow. It has the same 
 features of construction. The prin- 
 cipal difference being that it is 
 furnished in small sizes and can be 
 equipped with guiding handles, 
 which makes it possible to use it in 
 orchards, vineyards and in crops 
 that are planted in rows. 
 
 Work can be done with it in many 
 places where the ordinary spring- 
 tooth harrow cannot be used to 
 advantage. It is furnished with 7, 
 9, and 12 teeth. The 7-tooth har- 
 row cuts 1 foot, 11 inches; the 9- 
 tooth, 2 feet, 6 inches; the 12-tooth, 
 3 feet, 5 inches.

 McCormick Sulky Spring -Tooth Harrow 
 
 The McCormick sulky spring-tooth harrow 
 is exactly the same as the regular spring-tooth 
 harrow, except that a riding attachment has been 
 added and the posi- 
 tion of the levers 
 changed so that they 
 can be reached from 
 the driver's seat. 
 
 The sulky attach- 
 ments are made in two 
 sizes. The 17 and 
 23-tooth harrow takes 
 a slightly larger size 
 than the 15-tooth. 
 
 When ordering the 
 sulky attachment, 
 care should be taken 
 to designate the size 
 of harrow for which 
 it is to be used. 
 
 The sulky attach- 
 ment is so made that 
 the entire weight of 
 the driver can be put 
 on the harrow for 
 hard ground, or the 
 
 weight of the driver can be placed on the sulky wheels when working on so^t ground when it is not desired to 
 have the teeth penetrate so deeply. The wheels are placed within the frame of the harrow, where they do not 
 trail on the newly cultivated ground.

 The McCormick combination harrow is practically a spring-tooth and a peg-tooth harrow in one. The 
 trailing teeth follow along in the rear of the spring teeth, smoothing and leveling the ground and breaking up 
 the clods while they are soft. This makes the combination harrow a particularly desirable implement for use 
 when a farmer must prepare his seed bed hurriedly. The McCormick combination harrow has all the advan- 
 tages of the regular McCormick spring-tooth harrow and, in addition, has the advantage of smoothing the ground 
 at the same time. The frames on the McCormick combination harrow are high and pass over trash readily. 
 The teeth are spaced so that trailing is impossible. More or less slant can be put on the trailing teeth in the 
 rear, as conditions require. ■ m The McCormick combi-

 McCormick 14-Tooth Cultivator 
 
 The teeth on the 
 
 14-tooth cultivator 
 
 are adjustable 
 
 McCormick 14-tooth cultivator with straight bar frame 
 
 The McCormick 14-tooth cultivator is designed for deep, 
 level cultivation. It is adapted to the use of truck gardeners, fruit 
 growers, and those who need a tool for deep stirring of the ground 
 without hilling. The teeth are diamond shaped with a small 
 point forged on the end. It can be adjust- 
 ed to cultivate at different depths and at 
 different angles, so that very close work 
 can be done. 
 
 The cultivator is furnished with or 
 without a wheel jack. The depth of cul- 
 tivation can be regulated with the wheel 
 jack and the clevis hitch. The expanding 
 lever is a double locking device which 
 makes the cultivator exceedingly rigid, 
 whether the frame is expanded or closed. 
 The teeth in the quadrant are very fine, 
 permitting close adjustment. This enables 
 the opeiator to cultivate as near as he 
 desires to plants in rows of unequal width. 
 
 The McCormick 14-tooth cultivator 
 is furnished with straight or zigzag bar 
 frame with expansion screw or 
 expanding lever. On special 
 order and at a slight additional 
 cost, this cultivator will be 
 equipped with double-pointed 
 teeth, giving the advantage of 
 reversing the teeth end for end 
 when one end becomes worn. 
 Teeth for destroying thistles and 
 weeds with thick stalks will be 
 furnished on special order. 
 
 A reversible, dou- 
 ble-pointed tooth 
 can be furnished 
 on special order at 
 additional cost

 McCormick Combination Cultivators 
 
 McCormick cultivator No, 51 
 
 McCormick combination cultivators are made for 
 all purposes where a one-horse cultivator is re- 
 quired. It is not necessary that the rows be of 
 uniform width. These cultivators can be quickly 
 adjusted for wide or narrow cultivation. They are 
 equipped with all the attachments necessary to 
 cultivate all kinds of crops. They are made in 
 three types, 5, 7, or 9-shovel. Nos. 51, 52, 53, 54, 
 and 55 comprise the 5-shovel series: Nos. 71, 72, 
 7.>, 74, and 75, the 7-shovel type; Nos. 91, 92, 93, 
 94, 95, the 9-shovel type. 
 
 The frames of all these harrows are made the 
 same, consequently, by purchasing various attach- 
 ments, the 7 and 9-shovel type can be made from 
 the 5-shovel type, thus the farmer can have a culti- 
 vator for all purposes, enabling him to do the best 
 cultivating under all conditions. 
 
 McCormick cultivator No. 53 
 
 Shovels 
 
 The shovels on the McCormick combination cul- 
 tivator are reversible, affording two cutting edge? 
 They are thicker in the center than on the edge, so 
 that they retain their original shape until complete- 
 ly worn out. The frame on the McCormick culti- 
 vator is made of bar steel, and is fastened in such 
 a manner that it presents the shovel as squarely as 
 possible to the ground, whether the harrow is 
 expanded or closed. The hole through the shovel 
 is square, and the metal is raised on the back so 
 that there is very little chance of the shovels ever 
 working loose. 
 
 Moldboards 
 
 The moldboards are arranged similar to the 
 moldboard and point of a plow. They are reversi- 
 ble, the same as the shovels. When one point 
 becomes worn the other can be used. They can be 
 adjusted to throw dirt toward or away from the 
 plants. They can also be used for hilling.

 Works as Close to the Plants 
 as Desired 
 
 The wheel jack is exceptionally strong and is 
 made so that the teeth can be regulated by it as 
 well as by the clevis hook. The clevis locks so that 
 it is impossible for the singletree to come out when 
 the horse backs. 
 
 The lever wheel jack used in connection with the 
 expansion lever on cultivators Nos. 55, 75, and 95, 
 makes it impossible for the operator to c.ulti-vate 
 between rows of different widths, without stopping 
 the horse to make adjustments. This makes these 
 cultivators of exceptional value to the truck grower. 
 
 The improved lever expanding device used on 
 the McConnick cultivator holds the cultivator frame 
 exceptionally rigid, whether closed or expanded. 
 The teeth are so spaced that close adjustments can 
 be made when the cultivator is in operation. This 
 is of particular value, because it gives the operator 
 an opportunity to adjust his cultivation with vary- 
 ing widths of rows, and get as close to the plants as 
 he desires.
