Firebug 267 #1 Posted July 24, 2019 I put a new pto to deck belt on today. 1/2x97 for the rd deck. I have the attach o magic adjusted all the way out, there is still a lot of slop in the belt to where it will come occ the deck pulley. Any thoughts? Share this post Link to post Share on other sites
The Tuul Crib 7,336 #2 Posted July 24, 2019 Sounds like the belt is alittle long. Share this post Link to post Share on other sites

lynnmor 7,302 #5 Posted July 24, 2019 Are you sure that the deck is mounted properly in the mid hitch? The fork should be straddling a pin. 1 Share this post Link to post Share on other sites
Firebug 267 #6 Posted July 24, 2019 It is. I just mowed with it the other day with no issues. The new belt is a hare shorter than the old one, I figured that was the stretch in the belt from use Share this post Link to post Share on other sites
tunahead72 2,411 #7 Posted July 24, 2019 I'm starting to think @lynnmor is on to something... I just did a quick check of the 42" rear discharge decks that were available for the 314-8, and came up with the 05-42MR03 in 1985 and the 78350 in 1993-2001. Both of these specify drive belt #108834, 1/2"x98". So, what belt did you just install? And is this a new problem since you installed it, or was there a similar problem with the old belt? Also, what engine does your tractor have? It should be a Kohler, either K321, Magnum14 or Champion14. I don't know if it makes a difference, but it might help.

Firebug 267 #10 Posted July 24, 2019 It’s a 93 with the magnum 14. I put on a 1/2x97 which I was told is the belt in another post I had on there. It is on the inside groove on the pto. Share this post Link to post Share on other sites

daveoman1966 3,745 #12 Posted July 24, 2019 The belt MUST be in the INNER MOST 'V' of the PTO pulley. I bet that is the problem. If not that, maytbe the deck isn't mounted correctly...OR T two pulleys on the front Mule Driver...the Flat Idler and the V pulley are wrong. They should be about 4" diameter.

Ed Kennell 38,024 #13 Posted July 24, 2019 (edited) I'll take a guess that the belt is not on one of the mule drive pulleys. Edited July 24, 2019 by Ed Kennell Share this post Link to post Share on other sites

Ed Kennell 38,024 #15 Posted July 25, 2019 (edited) Just wondering......Is the new shorter belt still too long? Could the old belt be a 5/8" and the new one 1/2"? Edited July 25, 2019 by Ed Kennell Share this post Link to post Share on other sites
Tonyp 284 #16 Posted July 27, 2019 also check the round shaft rod ( side to side ) on the tach-o-matic mount that the tension adjustment screw secures against, make sure it's not bent backwards slightly. . This is NOT uncommon. Share this post Link to post Share on other sites
