A power take-off shaft system includes an output shaft with a socket for a power take-off shaft stub located at one end of the output shaft. A control valve is arranged in the output shaft and includes a valve bore extending axially from the socket into the output shaft. A first piston is adjustably arranged inside the valve bore in the output shaft, and a shifting element is adjustably controlled by the first piston. A first gearwheel and a second gearwheel are disposed in engagement with the output shaft via the shifting element such that the first piston moves between a first position and a second position. The control valve includes a second piston arranged on the first piston, and the second piston is adjustable such that movement of the first piston into the second position is blocked by the second piston.

A safety guard support for a power take off shaft, the safety guard support including a bearing; and a retainer ring. The bearing and the retainer ring including corresponding interlocking formations configured to prevent rotation of the bearing relative the retainer ring about a longitudinal axis.

A localized hydraulic circuit configuration detection and loading arrangement, and method, utilize a pattern of pins in an electrical interface connector that is unique to a particular hydraulically powered product delivery unit mounted on a self-propelled agricultural product applicator to close or leave open electrical circuits in solenoid operated pump control valve arrangements for selectively connecting a flow of hydraulic fluid at an operating pressure from one or more continuously operating pumps of the applicator to the product delivery unit, or for selectively bypassing the flow of fluid from one or more of the pumps back to a hydraulic reservoir of the applicator at a low, bypass pressure. When no product delivery unit is mounted on the applicator, the flows from all of the pumps are bypassed to the reservoir at the low, bypass pressure.

A drive over mower deck automatic locking mechanism includes a lift frame engaging a drive over mower deck, and a pair of locking plates pivotably connected to the lift frame. The locking plates lock the drive over mower deck to the lift frame when the lift frame raises the drive over mower deck to a mowing or transport position, and unlock the drive over mower deck from the lift frame when the lift frame lowers the drive over mower deck to an installation position.
