ABSTRACT:
A draft control mechanism for a tractor having a three-point hitch for attachment of a ground-engaging implement. The draft control mechanism utilizes an upper link arm connected to the tractor with a single load pin which houses a strain sensor for generating the control signals to control a lift mechanism connected to the implement. The pin is attached between two flanges of an upper link bracket to the rear of the tractor. Each flange includes a bushing surrounding the portion of the pin disposed therein. The pin includes a pin extension protruding from the outer side of one of the bracket flanges. A sealing cover is disposed over the pin extension with a rotation stop to restrict pin rotation.
