摘要： A control system for use in a vehicle having left and right clutch assemblies, each clutch assembly including a brake mechanism and a drive mechanism. The control system includes a steering switch having a left steering position to actuate the left brake mechanism and the right drive mechanism, a neutral steering position to actuate the left and right drive mechanisms, and a right steering position to actuate the left drive mechanism and the right brake mechanism. The system may also include an operator switch having a first position to actuate brake mechanisms and disable the steering switch, and a second position that passes control of both brake clutch assemblies to the steering switch. The system may further include a brake switch having a brake position that actuates both brake mechanisms and disables the operator switch and the steering switch, and a drive position that passes control of both clutch assemblies to the operator switch.

摘要： A control system for use in a vehicle having left and right clutch assemblies, each including a brake mechanism and a drive mechanism. The control system includes a steering switch having multiple steering positions to actuate the corresponding brake mechanism and opposite drive mechanism and a neutral position to actuate both drive mechanisms. The system may also include an operator switch having a first position to actuate the brake mechanisms and disable the steering switch, and a second position that enables control of the brake clutch assemblies by the steering switch. The system may include a brake switch having a brake position that actuates both brake mechanisms and disables the operator and steering switches, and a drive position that passes control of both clutch assemblies to the operator switch.

摘要： An embodiment of the present invention involves a zero turn drive apparatus. The zero turn drive apparatus has a housing, which has a first and a second end. The housing has a first end cap mounted on the first end of the housing, and a second end cap mounted on the second end of the housing. A hydraulic pump is rotatably mounted on each end cap, and each hydraulic pump is driven by a pump input shaft. A gear chamber is interposed between each pump. A power take off mechanism is engaged to the housing, and an output shaft extends from the power take off mechanism. An input shaft, which is engaged to each of the pump input shafts, extends into the power take off mechanism and is selectively engaged to the output shaft.
