Mike Sullivan 0 #1 Posted May 6, 2023 The mower engagement handle will not stay engaged for more than ½ a minute. I have a 1990 520H tractor with a 78345 Mower Deck It looks like where the handle goes through the side plate and over to the engagement rod every thing is wore. Is there a way to bring it back to life? Share this post Link to post Share on other sites
lynnmor 7,842 #2 Posted May 7, 2023 Looks like both of the white plastic bushings are spent and out of place, replace them. I bought my last ones and from McMaster-Carr, I believe they sell black ones now. 1 1 Share this post Link to post Share on other sites
JoeM 8,384 #3 Posted May 7, 2023 One thing that has been a help for me is to make sure the rod that attaches at the PTO goes up through the connection point and not down through. Helps to have that up through when the lever cams over. Share this post Link to post Share on other sites

I don't think I've ever seen it that way, but you say it helps? Worth a try, just to see what happens. Share this post Link to post Share on other sites
