 International Tractor Disk Harrow 
 
 The "One-Man" Outfit 
 
 FOR tluirftiiylil.v d<)ul)le-di.sking a large acreage in a short time there is no implement 
 that t-in compare with the International tractor disk harrow. This is a big, strong, 
 powerful implement, built for the heaviest kind of work behind a tractor. It is 
 built in two sizes, one size for harrowing a strip 1(J feet wide and another size for 
 harrowing a strip 12 feet wide. The larger implement has 48 disks divided into four 
 gangs, and will thorouglil.v and completely douVile-disk a strip 12 feet wide — and when this 
 harrow has followed the plow the ground is almost invariably ready for the drill. 
 
 Trailers Can be Used 
 
 Spring harrows, peg harrows, or seeding machines can be used behind the Interna- 
 tional tractor disk harrow. A strong eye is provided which is fastened rigidly to the rear 
 of the tractor harrow frame. It is a great time saver to be able to do the disking, 
 smoothing and seeding at one operation. The unusual strength of the International 
 tractor disk harrow makes this possible. 
 
 This is a "One-Man" Outfit 
 
 The International has tlic great advantage of being a one-man outfit. The man wlio 
 drives the tractor operates the harrow — no other o])erator is needed. 
 
 One Hand-Wheel Angles All Gangs at Once 
 
 A large hand wheel, which is carried close to the operator, in the cab of the 
 tractor, changes the angles of all of the gangs at the same time. This hand wheel is large 
 and convenient. All of the levers which it operates work with powerful advantages, 
 making it easy for the engine operator to change the angles of all of the gangs at once. 
 The levers and rods used in setting the gangs at their proper angles are of amjile size.

 Strong, One-Piece Frames 
 
 HE frames used on the front and rear ganys are practically the same. Each is built 
 of one continuous piece of heavy anyle steel, i-igidly bolted to the heavy steel 
 angles, which form the liacklione of the hai-row. The corners of these frames are 
 held rigidly by flat, steel corner braces. 
 
 The Gangs Can Always be Kept Level 
 
 The front gangs are held level at all times by the heavy, steel-angle center framing, 
 while the rear gangs are held level by angle steel straps which act on the angle steel cross 
 braces of tiie rear frame. The gangs are i)ivoted on strong pivots located back of the 
 center line of the arbor bolts so that the front gangs can roll together on their l)um])ers, 
 relieving the bearings of all end thrust. The pull is transmitted to the gangs by heavy 
 strap-iron drawbars working over large spools at the coiners of the fraines. By this 
 means the pull is applied at three points on each gang. There is no danger of bending an 
 arbor bolt. 
 
 Bearings 
 
 All of the bearings used on the International tractor disk harrow are made of a 
 special quality of hard iron and are made as nearly dust proof as it is possible to make a 
 disk harrow. The rear gangs are built with a thrust bearing on the outside {which is 
 the proper location for a thrust bearing). All bearings are equipped with grease cups, 
 permitting the use of grease (or hard oil) which is the most satisfactory material for 
 lubricating an implement of this kind. These grease cups have caps which are made to 
 take a wrench. Thus, the gi'ease can be forced into the bearings in cold weather.

 Forecarriage 
 
 THE Intcrnationiil tractor disk h:irrow is roguhirly equipped 
 with a forecarriage, which is of great value in keejiing the 
 harrow running steadily. The forecarriage wheels are 
 fitted with grease cups and dust-proof lieaiings, the grease 
 cups being located between the spokes where obstructions on the 
 ground cannot loosen them. The forecarriage wheel axle is 
 swiveled, iJermitting the forecarriage wheels to follow the uneven- 
 ness of the ground. The forecarriage is of especial value when 
 the tractor harrow is used after the plow. 
 
 Scrapers 
 
 All of the disks are equipped with spring steel, one-piece 
 scrai)ers, each of which can be adjusted to press as tightly against 
 the disk as desired. They are made of a special shape, which is 
 
 particularly well adapted to keeping the disks clean. The scrapers are held in place by a 
 
 heavy steel angle, which is firmly bolted to the gang frame. 
 
 Steel Weight Boxes 
 The International tractor disk harrow is regularly equipped with two weight boxes, placed 
 on the forward gangs. These weight boxes are made of steel bars and angles. They are of 
 great value when working in ditficult ground. 
 
 The International Disk Harrow^ Gives Satisfaction 
 
 Tlie International tractor disk harrow has given thoroughly satisfactory service to all who 
 have used it. It is an unusually heavy machine — one that will get right down to its work and 
 cut its way through, chopping up the clods. The use of the International tractor disk harrow 
 after the plowing has been done, with a spring tooth or peg tooth harrow trailing behind, and a 
 seeding machine behind the smoothing harrow, is the quickest and best method of preparing 
 a good seed bed and gettmg the crops into the ground under the best possible conditions.
