ABSTRACT:
A system configured to drive a fan of an agricultural applicator is provided. The fan is mounted on a wheeled chassis assembly propelled via a drive train by an engine in a forward direction of travel. The system includes a hydraulic pump mechanically driven by the engine. The hydraulic pump is connected to drive the fan in creating a pressurized air stream to distribute product from the applicator across a field. The system further includes a stroke limiter mechanically connected to the hydraulic pump. When the engine slows below a threshold speed, the stroke limiter automatically diverts a portion of a power demand by the hydraulic pump via the drive train to drive movement of the wheeled chassis assembly.
