[QUOTE="skidsteer.ca, post: 25187, member: 307"] To clarify a bit. When you stop the flow, the inertia of the spinning blades turn the hyd motor into a pump. It generates pressure in the return line to the loader. Both the lines to the loader are blocked so the oil can't go there once you shut off the flow. I just T'd a line in between the pressure and return hose so the return line pressures goes back to the inlet side of the hyd motor. You must however also add a 1 way flow valve known as a “check valve” so when the loader is pumping the oil the check prevents it from going through the bypass line and forces the flow through the cutter motor. Now if you use this on your auger you will not be able to reverse the bit, unless you add a shutoff valve to the bypass loop. A 1/2“ check is available from surplus center for about 25 and and a shut off valve is 40 to 50. Ken [/QUOTE]
