[QUOTE="frogfarmer, post: 36755, member: 4075"] Do you ever notice a problem with the hyd oil foaming? A flow restricter can cause the oil to foam under certain conditions. Most implements like stump grinders have flow control built in to the valving so the head doesn't jump all over the place. Some valves are setup to maintain back pressure on the system to help avoid the problem you are experiencing. Cavatation in the drive motor of the cutting head could cause air. Just a thought but still sounds like air; problem is where did it come from. [/QUOTE]
