摘要： A hybrid drive system for a utility vehicle (1) which operates with an internal combustion engine (12) an an electrical generator (80), motor (86) and storage means (84). Auxiliary hydraulic functions (93,94) may be powered by the electric motor (86). An output of the engine (12) is mechanically coupled to a multi-ratio transmission (10) which has a hydrostatic driveline (24) and an output which is mechanically coupled to propulsion means. With the engine switched off, the electric motor powers a hydraulic pump (91) which generates pressurised fluid to operate auxiliary functions. In addition, the pressurised fluid may be exploited in a secondary propulsion mode to drive a hydraulic motor (92) in the hydrostatic transmission to propel the vehicle in a low emission, low noise output mode.

摘要： A zero turning radius mower has an internal combustion engine mounted transversely on a pair of longitudinal frame members behind an operator seat and a pair of rear drive wheels. The engine rotates a flywheel on a horizontal axis perpendicular to the longitudinal frame members. A gearbox is mounted to one of the longitudinal frame members, with a horizontal input shaft driven by the engine and a vertical output shaft engaging one or more rubber belts. The same rubber belts drive a pair hydrostatic transmissions for the pair of rear drive wheels and a plurality of rotary mower blades under a mower deck.
