Abstract: A vehicle such as a motor grader includes a hydrostatic auxiliary front wheel drive system which utilizes implement system pressurized fluid flow to drive a pair of fixed displacement hydraulic motors, such motors being drivingly connected to cause rotation of the front wheels. A pilot operated series-parallel valve in combination with a flow divider allows the motors to be driven in series or in parallel. A directional control valve is selectively responsive to operator control, and clutch actuation is accomplished automatically by directing a controlled portion of system fluid to such clutches to overcome the normal spring bias thereof.

Abstract: A tractor-implement arrangement for establishing a frictional connection between the power take-off shaft of a tractor and a Cardan shaft for the drive of a movable implement by an automatic coupling of members respectivaly connected to the power take-off shaft and the Cardan shaft. The implement is connected to the tractor by means of automatically interengaging coupling members or elements while one and/or the other coupling element of the power take-off or Cardan shaft is axially displaceable while being spring urged. The Cardan shaft is supported by suitable holding means and is liftable by a lifting device. The Cardan shaft is moved first by guiding the same along an inclined plane toward the take-off shaft and is frictionally coupled thereto whereupon the implement is mounted on the tractor by interengagement of additional coupling members.

Abstract: This invention relates to push rod apparatus for propelling wheel chairs. Several different embodiments of the invention are disclosed. All the embodiments include a plurality of push rod mechanisms that provide the occupant with a means to propel a wheel chair in a forward and reverse direction. In addition, the push rod mechanisms of the various embodiments all include means to move the push rods away from and toward the center of the rear wheels of the wheel chair to which the push rods have been added. The push rods are extended away from the rear wheels of the wheel chair when in their uppermost position to place the push rods in a better position to be engaged by the occupant of the wheel chair and retract toward the center of the rear wheels in their lowermost position so that the push rods will not contact the surface on which the wheel chair is moving.

Abstract: A vehicle chassis is formed from front and rear wheeled chassis units, the front unit providing the steering and the rear unit the drive.
