The Easy-Change Three-Point Hitching System link ends fit over the ends of the tractor's three-point hitch lift arms, transforming them into a quick-hitch (reportedly requiring less than a minute). It's attached with a pin through the ball and a U-bolt for stability. Hitching works as follows: with the lift arms in down position and the System's hooks open, the operator (1) backs the tractor into the implement, (2) raises the lift arms to hook the pins on the implement, (3) closes the spring-loaded latch, and (4) attaches the top link (and PTO shaft, if needed). Besides the standard Category 1, 2, and 3 models, others include Cat 1 receiver with Cat 2 hook, Cat 2 receiver with Cat 1 hook, Cat 2 receiver with Cat 3 hook, and a weld-on model. The unit comes with adjustable stabilizing bar and six lynch-pin washers.
