ABSTRACT:
An apparatus for extending the frame of a conventional tractor whereby an agricultural implement may be mounted between the front and rear wheels of the tractor. A tractor is converted to an extended frame tractor by dismounting the front wheels of the tractor, attaching the extension frame to the frame of the tractor and then mounting the front wheels on the front of the extension frame. Extension power lines for powering the steering mechanism and the hitch control mechanism are coupled between the tractor power lines and the remounted front wheel assembly. The extension frame is also articulated at its connection point to the frame of the tractor for improved control of the tractor assembly. A mechanism is provided for shifting the farm implement laterally with respect to the front wheels of the tractor for proper alignment of the implement with the crop rows. Spring shock absorbers are also provided for cushioning forces to the agricultural implement caused by uneven terrain.
