You have to have the RPMs up so the PTO will spin the grinding wheel fast enough. Then the GPM is at the max. I had the flow restricted but that cause the pump to really squeal so I removed it.

Where did you put the restriction?

It should have gone after the work port and close to the cyl port.

You then only feed a little fluid to the cyl, and the remaining fluid from the pump just passes on to the tank.

I put it coming out of the work port.

J.J. I would like to have a joystick valve to control the stump grinder. I might use one spool to control hydraulic side link later. I am looking at this one Surplus Center - 2 SPOOL 14 GPM PRINCE LVR JOYSTICK LOADER VALVE after returning the one I ordered by mistake. Do you recommend one that would better fit my needs?

If you have to have a joystick valve that valve is OK.

Here is the PB section.

Here is an option for you.

A two valve solenoid 3rd function setup will give you a two cyl control, left/right, up/dpwn.

With this valve setup mounted on the tractor, you could stand off to the side with a 20 ft cable box with switches and control the stump grinder by pressing buttons or switches.

With a third cyl, you could go fwd and rev moving the stump grinder head.

Now, you have three planes.

I think the joystick would be easier to control the grinder, and take up less room when mounting. I want to mount it beside the seat, next to the stock rear remote lever. I was thinking of a diverter to control the side link, if/when I install. I will use the stock remotes for the top link.
