Abstract
A three point hitch for a cart-type utility vehicle wherein the utility vehicle comprises a vehicle frame that includes an axle housing and an upper frame cross member. The three point hitch comprises a pair of spaced apart lower draft links, each pivotally mounted to the axle housing and extending rearward, the lower draft links having connection features at free ends thereof for connecting to an implement. A beam extends in a lateral direction parallel to the upper frame cross member. A rockshaft extends parallel to the beam and is pivotally connected to the beam. A lift bracket is fixedly connected to the rockshaft. Two upper links are fixedly connected to the rockshaft and extend rearward, the upper links located above the lower draft links. Two vertical links connect the upper links and the lower draft links. Endplates are fixedly connected to the beam and are connected to the vehicle frame by pins that also are used to pivotally connect a cargo box or platform to the frame. A bracket assembly is configured to capture the upper frame cross member and brace against the beam. The bracket assembly extends to a cylinder connection below the rockshaft. A hydraulic cylinder is connected between the cylinder connection and the lift bracket. Expansion of the hydraulic cylinder rotates the rockshaft to lift the lower draft links.
