I have 500 bushels of corn in the cart behind the 8670 right now. I tried to unload the corn and the pto engaged normally, but as soon as I opened the slide on the cart and put some weight on the auger, the pto stopped turning. I revved the engine up and tried moving the hydraulic slide up and down and the pto did not respond. I closed the slide and dumped the corn from the bottom dump to get the weight off the auger and the pto would turn. As soon as I put the weight back on it, it stopped again.
I haven't had any problems with the PTO in the past, except I did replace the PTO brake on it in 2012 with bern's and other forum members' help. It was last used to run a 15 foot batwing mower with no problems. There is a fitting on top of the rear cover, like a small quick coupler that is marked PTO, and one on the side marked PTO BRAKE PRESS. I'd imagine I would need a female coupler and a gauge to measure the PTO pressure. I am going to take the fitting out, and to a local hydraulic shop to get a test gauge built.
What pressure should I have and how do I adjust it, if it is low?
All of the other hydraulic functions work just fine on the tractor and the transmission is not low on fluid. The filter was changed last year, or about 250 hours ago.
Any help would be appreciated. I wish I would have bought a service manual for this tractor. Darn thing has been so reliable, and low houred(4026 hrs), I figured I wouldn't need it. Go figure...
