    摘要： A return to neutral mechanism (10) for a dual hydrostatic transmission includes a plurality of return to neutral control arms (41, 42, 51, 52), each return to neutral control arm (41, 42, 51, 52) biased toward a neutral position. Each return to neutral control arm (41, 42, 51, 52) moves in response to forward or reverse movement of an operator control (76, 78), such as a stick or foot pedal. Additionally, switches (61, 62) are mounted to the return to neutral control arms (41, 42, 51, 52). The switches (61, 62) enable starting of the engine if every return to neutral control arm (41, 42, 51, 52) is in a neutral position, and disable starting of the engine if at least one return to neutral control arm (41, 42, 51, 52) is out of the neutral position.

    摘要： A hydrostatic transmission (10) includes a pump valve body (11) with high pressure ports (19, 20) through which hydraulic fluid flows between a pump (13) and a motor, a bypass orifice (47) extending between the high pressure ports (19, 20) and the outside of the pump valve body (11), a bleed poppet (45, 46) movable between a closed position blocking the bypass orifice (47) and an open position opening the bypass orifice (47), and a poppet push pin (43, 44) moving the bleed poppet (45, 46) toward the open position if the hydrostatic transmission (10) is in neutral, and toward the closed position if the hydrostatic transmission (10) is in forward or reverse.

    摘要： A variable width mower deck (10) has three cutting chambers (15, 16, 17) mounted under a top deck surface (11). Two of the cutting chambers (15, 17) may be moved between a retracted cutting position and an extended cutting position. An endless belt (27) engages the pulleys (25, 28, 29) on each spindle (21, 22, 23) to rotate the rotary cutting blades (18, 19, 20). The left and right cutting chambers (15, 17) move between the retracted and extended positions while maintaining engagement between the endless belt (26) and the pulleys (25, 28, 29).
