A hydrostatic transmission system includes a pump including a rotatable swash plate, wherein rotation of the swashplate effects a change in volumetric displacement of the pump. An actuator is coupled to the swashplate, the actuator operative to effect rotation of the swashplate to change the volumetric displacement of the pump. An electronic controller is operatively coupled to the actuator, the electronic controller configured to command the actuator to effect rotation of the swashplate.

A multi-coupling includes a fixed plate and a free plate, and a primary locking mechanism for locking the free plate to the fixed plate aligned to form multiple fluid passages through the multi-coupling. The primary locking mechanism may include a drive screw secured to the fixed plate engaged with a drive nut secured to the free plate, and a clam shell securing mechanism that secures the drive screw to the fixed plate. The clam shell halves are moveable to release the drive screw from the fixed plate independently of releasing drive screw from the drive nut. The multi-coupling further may include satellite locking mechanisms in combination with the primary locking mechanism. The satellite locking mechanisms may include satellite securing mechanisms that are moveable to release the satellite locking mechanism from the fixed plate. The locking mechanisms are removable while retaining the fixed plate fixed to base equipment.

A vehicle includes a pump having a swash plate tiltable about a swashplate tilt axis, wherein rotation of the swashplate changes the title angle and effects a change in volumetric displacement of the pump. A controller is operatively coupled to the swashplate to effect rotation of the swashplate, the controller including a processor and memory, and logic stored in the memory and executable by the processor, the logic configured to automatically control at least one vehicle characteristic independent of a user input command.
