ABSTRACT:
A tractor-mounted apparatus is disclosed for supporting ballast weights on the front or rear of the tractor and for elevating the weights relative to the ground. The apparatus includes a pair of U-shaped channels fastened to frame members of the tractor in an upright position. The channels are aligned with their open faces opposite to one another such that the ballast weights can be received therebetween. A pair of hydraulic cylinders are each secured at one end to one of the U-shaped channels and each has an outwardly extending piston rod detachably coupled at its lower end to the ballast weights. The piston rods are moved into and out of the hydraulic cylinders by a control mechanism thereby permitting the ballast weights to be raised and lowered in a substantially vertical fashion. The apparatus also includes means for permanently locking the ballast weights to the U-shaped channels while the ends of the piston rods are connected to the lower links of an attached implement. In such an arrangement, actuation of the piston rods permits the implement to be raised and lowered with respect to the tractor's frame.
