One other quick note. Have you contacted Woods's tech support guys? Go to http://www.woodsonline.com site for the 800 # and give em a call. They seem really helpful.

I really think you've got something wrong if it's getting that hot. You shouldn't have to baby the hoe. Running at full tilt/pressure should not be a problem. Are you sure your reservoir is full and have you changed the filter? Are you sure eveything is plumbed correctly? If, for example, the fluid return is going right to the pump intake rather than circulating through the tank to disapate heat, that would cause what you are seeing.

Can you test the fluid in the reservoir to see if it's hot too? Maybe just feel the side of the tank. Are all the cyls hot or just some of them.

Hayden,

Thanks. I have felt the temperature of the tank, hoses, all the cylinders, and PTO pump. Everything gets hot. A fluid and filter change did not help.

It takes about 1>1.5 hours of working, digging 6' deep by 12" wide trenches to get to the hot temperature. The hoe came from Woods pre assembled and the dealer did the final setup. It seems to dig great. This is really the first time I have worked the hoe so hard and for so long. Usually I am digging some shallow short trenches or just planting something.

I checked the fluid pickup in the tank to make sure it was clean. The high pressure hose is routed to the joystick controls. The low pressure return is routed to first to the filter and then the tank return. The return hose does not feed directly back into the pump (I had the same thought).

I guess I will call Woods tomorrow to see what they think. The dealer did not have any sugestions beyond what I have already tried.

Well, you've already checked everything I can think of. A call to woods sounds like a good idea. Maybe it's OK after all.

Good luck,

Peter

Early on in this thread somebody mentioned a desirable ratio between gpm flow and reservoir capacity. I hadn't thought of that issue, but it seems like it might be a good idea to revisit.
