just1redone 0 #1 Posted August 2, 2014 I have a 87 310-8 with a 5 1010 8 SD deck that when I am mowing the deck slows down. I put a new 103" belt on it thinking it was slipping but it is still doing the same thing. It seems like the PTO is slowing down. Any Ideas? Share this post Link to post Share on other sites
Sparky-(Admin) 19,703 #2 Posted August 2, 2014 Is the PTO adjusted properly? The PTO engagement rod/handle should give a bit of resistance when you push it all the way forward to engage the PTO. The end of the PTO rod is threaded and a couple turns of the trunion will add tension if it needs more. Mike............ Share this post Link to post Share on other sites
Geno 1,928 #3 Posted August 2, 2014 Do you smell the clutch burning? If so go by Mike's suggestion. Share this post Link to post Share on other sites
just1redone 0 #4 Posted August 3, 2014 The PTO rod is adjusted all the way up. Could the belt be too long? Share this post Link to post Share on other sites
Geno 1,928 #5 Posted August 3, 2014 Just because the PTO rod is adjusted all the way up doesn't mean it isn't slipping. Share this post Link to post Share on other sites
just1redone 0 #6 Posted August 3, 2014 I took the PTO apart to check the friction disc and that seemed fine. Inner bearing seems fine. Outer bearing seems a little noisy. Share this post Link to post Share on other sites
