 speed drop/lock valve

I just bought a used 160 hours JD 4100. It doesn't look like PTO has ever been used, and speed drop/lock valve won"t turn, and lift arms don"t respond to appropriate operation lever. Any suggestions? (Tractor only as a bucket and to my knowledge never used a rear mower or under body mower.) Thanks, Martin

 speed drop/lock valve

If it has not been used in a long time it's likely just stuck from not being turned. The last person who closed the valve mail also over tightened it. If both of those, applyit will be terribly difficult to open the valve.

I would suggest a trick I used before with success. Wrap a rag around the control knob and make several passes around the knob, then take the end of the rag and grip it tightly with a pair of vise grip pliers and use the vice grips as leverage against the stem to turn the knob.

This will grip far tighter than you could by hand.


Best of luck.
