View the plow is shown in position relatively The forward furrow-wheel F is preferably to the wheels to make the first furrow. In tilted or inclined outwardly and mounted suchcase, itwill'loev observed, the land-side uponthe laterally-projecting lower portion of and the forward furrow wheel travel on the the standard or-spindlef. A box-like casting I00 50 surface of the ground. Fig. 2 is a view simif is preferably mounted and arranged to prolar to Fig. 1, but :showing the forward furvide a bearing for this said spindle or standlll ard. A second casting or inclosing member f is secured rigidly to the plow-beam. The disk-like member f is inclosed by these two relatively sliding castings or members and is provided with a shaft f arranged to extend through vertical slots f formed in the side walls of the castingf. Thus, it will be observed, the two castings are capable of relative and vertical and sliding movement, and the two castings are connected and held against separation by their relative formation. The casting f is preferably connected with the peripheral portion of said disk by one or more linksf In a similar manner the casting f is connected with the opposite side of said disk by one or more links f lVith this arrangement -it will be seen that a rotation of this disk in one direction will cause it to move bodily upward, carrying the castingf and consequently the plow-beam, with it. A rotation of the disk in an opposite direction will cause it to move bodily downward, and to consequently lower the casting f and the plow-beam. The means for thus rotating said disk consist, preferably, of a crank-arm f on the shaft of the disk and of a link f arranged to connect this crankarm with the lever D. lVith this arrangement the forward portion of the plow-beam can be raised and lowered upon the spindle or standard f by operating the lever D. The rear trailing or caster wheel G is also preferably tilted orinclined, so as to follow properly in the furrow being made by the plow, and is mounted upon the lower laterallyprojecting portion of the stem or spindle g. This stem or spindle, it will be observed, is arranged to turn freelyin the castingg, which supports said seat. This casting g has a vertical sliding or relative shifting movement with respect to the casting 9 which latter is secured rigidly to the rear portion of the plowbeam. This arrangement, it will be observed, is similar to the arrangement for adjusting the forward furrow-wheel. The side walls of the castings are provided with slots 9 adapted to receive the projecting end portions of the shaft 9 On this shaft 9 a disk 9 similar to the one previously described, is mounted, and one side of this disk is connected with the casting g by one or more links g At the opposite side the disk is connected with the casting g by means of similar links The projecting end portion of the shaft 9 is provided with a crank-arm g and this crankarm is connected by a link g with the lever D. \Vith this arrangement it will be seen that a relative shift or sliding movement between the two castings g and g can be caused by operating the lever D. This relative shift or sliding movement is of such character as to cause the rear portion of the plow to be raised or lowered, according to the direction in which the lever is swung. In other words, a shift of said lever in one direction will rotate the disk 9 in such direction as to cause it to move bodily upward and lift the plow and beam with it. Also the movement of the lever in an opposite direction will'cause the disk g to rotate and move bodily downward, thereby lowering the rear portion of the plow and beam. The arrangement, it will be seen, permits the rear caster-wheel to turn clear around and to swing freely below the rearwardly-projecting arm of the casting 9'. As a means for holding the caster-wheel against turning while the machine is running straight ahead the upper end of the caster-wheel spindle 9 can be provided with a crank-arm g This crank-arm can be connected in any suitable manner with the tongue II, which, it will be observed, is secured to the upper end of the spindle f. For example, the said tongue can he hinged to the casting h, and the latter can be provided with a transversely-extend.- ing slot h. The rod 72/ can be arranged to connect the crank-arm g with the slotted portion of the casting h. Thus when the machine is running straight ahead the rear caster wheel is held against turning; but when the tongue and forward furrow-wheel are swung to one side, as in turning around, then the forward end of the rod 72, becomes free to play in the slot h. In this way, as soon as the tongue and forward furrow-wheel are swung to either side the connection between the caster-wheel and the tongue is practically released, so as to permit the casterwheel spindle to turn freely in its hearing.

In operation the first furrow can be made by adjusting the plow and wheels relatively, as shown in Fig. 1. In this View it will be seen that the land-side and front furrow wheels travel along the unplowed surface of the ground, while the rear trailing or caster wheel follows in the furrow being made by the plow. Subsequently, as will be understood, the levers are adjusted so as to bring the front furrow-wheel down into the previous furrow, as shown in Fig. 2. In this case the rear trailing or caster wheel follows in the furrow being made, the land-side wheel travels above on the unplowed ground, while the front furrow-wheel travels in the previous furrow. By grasping the lever D and releasing its bolt from the rack d all three wheels can be simultaneously controlled, so as to bodily raise or lower the plow, according to the direction in which the lever is swung. The lever E can,be employed to control the land-side wheel independently of the other wheels. lVith the form of shifting connection employed the rear furrow-wheel does not move toward and away from the plow when the latter is raised and lowered. In other words, the caster-wheel spindle and the plowbeam retain their distance apart at all points in the relative adjustment between the easter-wheel and the plow. Furthermore, these shifting connections, consisting of the rotary disks and links, are strong and simple and afford an efficient arrangement for securing the desired adjustments or movements of the plow. In addition these shifting connections,

although easily and readily operated, are of such characteras toinsureagainstloosejoints,

' and consequently as to insure against lateral yielding-orplay. In this way a thoroughly rigid and efficient construction is obtained without the necessity of employing any supi ing the lever E stationary the lever D can be employed for controlling the front and rear furrow-wheels independently of the land-side wheel, and, furthermore, for a certain portion of its travel this lever D causes a relative movement of the front wheel independently of the others. For example, in Fig. 2 the front wheel is down in the furrow,.the rear wheel is following in the furrow being made, while theland-side wheel is traveling on the surface of the ground. In Fig. 1, however, the lever D has been thrown forward to an extent to lower the plow below the front wheel without disturbing the position of the rear wheel relatively to the plow.

7 When the plowvis lowered to the level of the front and rearfurrow-wheels, as shown in Fig. 2, the disk g is practically at the limit of its downward movement,and consequently a forward movement of the lever D from the position shown in Fig. 2 will, owing to the provision of the spring g lower the plow relatively to the front wheel only. In other .words, an adjustment of the lever D forward from the position shown in Fig. 2 coinpresses the spring g, as shown in Fig. 1, allowing the relation between the rear furrow-wheel and the plow to remain the same. It will be seen, however, that this extreme forward adjustment of the said lever lowers the plow-beam on the spindle f, or, in other words, practically lifts the front furrowwheel relatively to the plow, so as to allow the latter to assume the position necessary for making the first furrow, as shown in Fig. 1. In this way it will be seen that the'lever D is connected and arranged'for simultaneously adjusting bothfurrow-wheels up to a certain point in its swing and that-beyond such point the relative movement is confined to the forward furrow-wheel. As stated, the raising and lowering of the-plow causes no change in the distance between the plow and the rear furrow-wheel. Consequently the plow can be raised and lowered without any tendency on the part of the rod 71 to push or move the.

rear furrow-wheel around. The crank-arms for rotating the two disks can be adjustably connected with the studs or short shafts upon which the latter are mounted. For example, as shown .in Fig. 7-, the crank-arm g is connected with the shaft g bymeans of a toothed formation, such as is shown at 9 so as to permit the crank-arm to be adjusted to the proper angle relatively to the disk and links. With this arrangementthe connections between the two rotary disks and the leverD can be adjusted nicely, so as to secure the proper relative movements.
