SOURCE: John Deere D140 PTO clutch tries to engage but fails. Why?

Try the following test. For safety purposes remove spark plugs. Now with engine off and key in run position turn PTO on. You should hear the clutch engage (clunk). Grab both sides of the clutch pulley and try to rotate the pulley. If the clutch is properly engaged you will not be able to rotate the clutch pulley without turning the engine.

Testimonial: "Carl Rock was extremely helpful. Turns out the problem was the operator, but, he helped guide me through until I found my own mistake."

SOURCE: 2012 model D140 riding mower. How can I adjust belt(s)?

The mower deck tension is set by a spring so there are no adjustments. If belt is loose, check deck is mounted correctly and belt length is correct. Then check for loose pulleys or worn spindle and pulley bearings.
