Abstract: A front mounted ground supported tractor attachment, steerable with and pushed by the tractor, includes a portable frame supported on caster wheels and a drive linkage connected between the frame and tractor. The drive linkage is connected to the tractor for pivotal movement about a transverse axis and the frame is connected to the drive linkage by a swivel connection for pivotal movement about a longitudinal axis relative to the tractor. In one embodiment, the drive linkage engages the frame for transmitting the pushing force of the tractor to the frame substantially independently of the swivel connection and the caster wheels allow the frame to turn with the tractor as it is steered in the usual manner. Wear plates are carried on the engaged surfaces of the frame and drive linkage.

Abstract: A front mounted ground supported tractor attachment, steerable with and pushed by the tractor, includes a portable frame supported on caster wheels and a drive linkage connected between the frame and tractor for pivotal movement of the frame about both a transverse axis and a longitudinal axis relative to the tractor. The drive linkage transmits the forward motion of the tractor to the frame and the caster wheels allow the frame to turn with the tractor as it is steered in the usual manner. A pair of elongated push members on the drive linkage help push the frame while permitting it to pivot or swivel about the longitudinal axis. Abutment means limits the downward and forward pivotal movement of the frame relative to the tractor for safety.
