Dis-connect the hydraulic cylinder, & the 3pt will lower by gravity. The rotating rockshaft on the tractor will remain in the up position all the time without weight on it . If the Cylinder is attached the fluid will take the path of least resistance. This makes running a semi mount plow a problem because if more weight is on the cylinder the 3pt will come up first, & vice-versa.
