ABSTRACT:
A gage connected to the rod end of the wing cylinder on a multi-section implement senses rod end pressure at the output of the hydraulic wing control (HWC) valve. The HWC valve is engaged or disengaged using the selective control valve (SCV) in the tractor, and the gage provides a visual indication to the operator of the following modes: 1) off; 2) fold wings; 3) unfold wings; 4) field operation--push wings down; and 5) field operation--pull wings up. In field operation, the gage also provides an indication of the force with which the cylinders are pushing or pulling on the wings to affect the cutting force of the wings.
