A rotary mixer can include a frame, a rotor attached to the frame, four wheels attached to the frame for moving the rotary mixer, and a drive system for driving the four wheels, the drive system can include four independent hydrostatic drive loops, each of the independent hydrostatic drive loops associated with one of the wheels such that each one of the independent hydrostatic drive loops independently drives one of the four wheels; wherein the drive system includes a pressure balance mode of operation for relatively good traction ground or road conditions, and a wheel speed synchronization mode of operation for relatively poor traction ground or road conditions.

Traction control method for a rotary mixer

A hydrostatic drive including a hydrostatic pump configured to supply a transmission fluid. The hydrostatic drive further includes an axle motor and a drum motor. The axle motor is configured to drive a set of traction wheels and the drum motor is configured to drive a drum. The hydrostatic drive also includes an axle drive line and a drum drive line. The axle drive line and the drum drive line are connected to the axle motor and the drum motor respectively to supply the transmission fluid. A manifold integrally connected to the hydrostatic pump to operatively couple the axle drive line and the drum drive line with the hydrostatic pump.

Hydrostatic drive for a machine

A rotary cutter having a plurality of flights each having a tool holder receiving pocket extending radially inwardly from an outer surface of the flight. Each receiving pocket has a mounting socket at the innermost portion of the pocket which securely positions a tool holder, the tool holder being retained in the socket by a fastener.
