Auxiliary interlock control system for power machine

摘要

A skid steer loader (10) has an auxiliary coupling device (54) connected to the hydraulic circuit of the skid steer loader. An auxiliary control circuit includes a hydraulic valve coupled between the hydraulic circuit of the skid steer loader and the auxiliary coupling device. The auxiliary control circuit is coupled to an operator input and controls flow of hydraulic fluid between the hydraulic circuit of the skid steer loader and the auxiliary coupling device based on a control signal received from the operator input. In addition, a controller is coupled to an operating mode sensor and to the auxiliary control circuit and provides an output to control operation of the hydraulic valve controlling flow to the auxiliary coupling device based on the status of the operating mode sensor. <IMAGE>
