Trying to shred...the pto does not keep turning correctly in thick weeds. As i understand it my problem will be one of these..

1. hydraulic pump/pressure---assume this is good since batwings raise as does the shredder. Not slow, seems to work normally.

2.control valve

3.cable that works the control valve---with the pto disengaged the shafts on the shredder will still slowly rotate.....guessing that if the cable was not tight eneough this would not happen.

4.Pressure plates----how hard of a job is it to do?

anything else im missing or i need to know about?

You need to Tee in a gauge into the hyd. line that feeds the PTO. You need 200# plus pressure. If lower; (1) check cable adjustment to make sure spool is travling all the way to the engaged position.. (2)If spool travel is ok, there is a roll pin in the front of the valve that holds the spool that controls pto pressure. You can put a 5/16" flat washer behind the roll pin to raise pressure. (3) If these fixes don't work, you will have to pull the rear housing on the tractor, and check for worn, and warped clutch plates, and a bad brake.
