Sidepieces of the box are wide and are bolted to the vertical parts of the axle and braced in different directions to keep the frame solid, square and firm. The sides of the box are permanently fastened but both tailboard and front board are held in place by cleats and rods and are removable so that long scantling or lumber may be carried on the cart bottom. The ends of the box may be quickly put in place again when it is necessary to use them. To hold a cart box together, four rods are necessary, two across the front and two behind. They are made like tailboard rods in wagon boxes. There is always some kind of tongue or handle bar in front of the farm cart conveniently arranged for either pulling or pushing. If a breast bar is used it handles better when supported by two curved projecting shafts or pieces of bent wood, preferably the bent up extended ends of the bedpieces. The handle bar should be about three feet from the ground. [Illustration: Figure 168.--Farm Cart. The axle need not be heavier than 7/8". The hind axle of a light buggy works the best. It is bent down and spliced and welded under the box. The cart should be made narrow to prevent overloading. The box should be low enough to rest the back end on the ground at an angle of about 35° for easy loading.] COLT-BREAKING SULKY A pair of shafts that look a good deal too long, an axle, two wheels and a whiffletree are the principal parts of a colt-breaking sulky. The shafts are so long that a colt can kick his best without reaching anything behind. The principal danger is that he may come down with one hind leg over the shaft. It is a question with horsemen whether it is better to first start a colt alongside of an old, steady horse. But it is generally conceded that in no case should a colt be made fast in such a way that he could kick himself loose. Different farmers have different ideas in regard to training colts, but these breaking carts with extra long shafts are very much used in some parts of the country. The shafts are heavy enough so that the colts may be tied down to make kicking impossible. A rope or heavy strap reaching from one shaft to the other over the colt's hips will keep its hind feet pretty close to the ground. Any rig used in connection with a colt should be strong enough to withstand any strain that the colt may decide to put upon it. If the colt breaks something or breaks loose, it takes him a long time to forget the scare. Farm boys make these breaking carts by using wheels and hind axles of a worn-out buggy. This is well enough if the wheels are strong and shafts thoroughly bolted and braced. It is easy to make a mistake with a colt. To prevent accidents it is much better to have the harness and wagon amply strong.
