The Turbomist clevis system is 2 1/2inch sked 40 pipe 22 inches long, inserted inside a 3 inch pipe, with three hole locations predrilled to allow the operator to chose the lenght of the hitch needed to make the distance from the cross on the tractor to the draw pin to the distance from the pin to the cross on the sprayer. This setup, if done, guarantees that angle on any turn is equal at either end, this is to prevent driveline thrusting which can damage your driveline.This clevis system has either a true clevis style hitch end or a ball hitch , we use the hammerblow brand 2 5/16" ball , this allows for movement in hilly terrain, but requires you use a ball on the tractor drawbar as opposed to a pin thru the clevis, which can bind in hilly situations.
