Attached my mower deck the other day and when I backed the tractor out of my garage and went to throw the PTO engage lever, I found it incredibly stiff and hard to push down and lock in place. I tried operating it with brute force and ignorance but it wouldn't work. Now it is back to the original position but the tractor won't start which leads me to believe that the tractor still thinks it is in PTO mode. I suspect that my mid and rear PTO shafts are frozen and need to be broken loose but I am spit balling on that assumption. Any ideas? Mowing my acre and a half with a push mower is kicking my tail.
