A remote drop box can be provided for tractor hydraulic drives; however, a system for providing lubrication to and cooling of the remote drop box is necessary. Maximum drawbar pull and maximum road speed capability are both,desirable when a variable hydrostatic motor defines the working range. The hydrostatic motor must be operated very close to its maximum rated operating speed during roading, which leaves very little margin for overspeeding that occurs when the tractor is roading downhill. An improved overspeed control is also desirable. A problem encountered when a hydrostatic drive is used with a high torque engine in that, as the engine speed drops, the available charge pump flow also drops and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition needs to be alleviated to provide an effectively operating hydrostatic drive system. Load sensing hydrostatic drive systems can encounter vibrational or surging problems, particularly when flow compensators in valving interact with the flow compensator of the hydraulic pump. This interaction will cause rhythmic flow pulsations or surging within the hydraulic system, which is undesirable. Stabilizing the hydraulic system can be accomplished with an attenuator/hose assembly.
