Abstract
One or more techniques and/or systems are disclosed for adjusting the downward vertical force applied to the vehicle frame. In this way, an operator can adjust or distribute a vertical downward force that an attached implement applies to the frame of a vehicle towing the implement. A front end of a vertical load member can be pivotably coupled to the vehicle frame at a point in front of the rear axle of the vehicle, and a rear end of the vertical load member can be coupled to a hitch attachment assembly, coupled with a towed implement, at a rear end of the vertical load member. An actuator can be pivotably coupled with the vertical load member rearward of the vehicle axle, and to the vehicle frame. The vertical load member can be raised and lowered using the actuator, which raises and lowers the hitch assembly at the rear, and pivots the vertical load member at the front.
