Hello again. I'm helping a friend with a problem with his 312-H tractor and 42 inch rear discharge mower deck.  We've done a lot of work on this machine in the last year and the last problem is that the pto belt, or deck drive belt, is wearing out pretty quickly.  This will be the second belt this summer.  I have tried every belt routing I can see as possible, including reversing the idler pulleys on the forward right side of the tractor frame. We are using belt #108834, 1/2' x 98".  Is this normal??

WOW!   I've had the belt on mine forever.  How about some pictures of the belt at the PTO and the mule drive ( the idler pulleys on the forward right side of the tractor frame.  ) and at the deck.   Maybe someone will notice a problem.

Thanks N3PUY.  I have ordered another belt and will post pictures when I install it.  The last one shredded and broke so i cant show the routing. The people on Redsquare are awesome!

      Two PTO issues on GT-1848
      By davem1111
      I'm trying to figure out how to fix two problems: 
       
      1. Drive belt from PTO to deck keeps flipping over between the PTO and the mule.  Everything looks okay, belt runs right between mule and deck. It cuts just fine, but I'm concerned that running the belt on its back through the PTO will shorten its life a lot.
       
      2. PTO handle kicks off at random times while engaged. Not doing anything unusual, just cruising along mowing, and boom, it flips back.  Missing spring maybe?
       
      Any ideas?

      2 blade side discharge deck
      By RussAMC
      New to the forum, in fact never joined a forum of any kind before, so my apologies if I'm clumsy at this. I have aquired a 312-8 with a 2 blade deck and bagger. I believe it is a 37" but has been patched and painted and no longer has a id tag. I read previous posts on your forum stating that the mule drive with 1flat + 1 v pulley ( which is what I have ) required a v belt. Tractor had 6 sided belt that was pretty well shot and broke almost immediately. All pulleys on deck are v. Do I have the wrong mule drive ? Bought a v belt for it but seems like the idlers on the deck should be flat. Any help would be greatly appreciated thanks.

I am looking for the deck belt or at least the correct size. the deck is a model 5-0701 6 serial no. 806358. any help would go a long way. LOL my wife is not to happy I bought mowers that II could not just jump on to and mow!!

      Coach needs some coaching (help)
      By coach717
      Newbie here I bought an old 1988 Wheel Horse 111-6 it's a rear engine. I picked this up for $75.00 Put a new ignition switch in cleaned the carb installed a new battery and it fired right up. Amazing! What I havent been able to do is keep the pto belt working so the deck cuts. Is there an adjustment I can make to help insure that the belt stays engaged? Help I don't want to use that walk behind mower!!!
      Thanks,

      Pto belt problem
      By rogden
      Hey everyone I am new to Red Square, I just got a new to me, c160. I believe its a 1977, it came with a  rear discharge three blade 42 inch mowing deck. Listening to the 16hp kohler, idle sealed the deal for me, you just gotta love that sound!

      It had a brand new huffy blue belt on the pto running to the deck when i bought it. To make a long story short, it spewed white smoke under any load and burned up the belt in about 30 minutes. I did some research and determined the belt must have been to loose, so I cleaned up the tractor, went and got another huffy blue belt 96 x 1/2 installed it...tightened that mutha up and cut some grass.  I have about 2 acres and the grass was tall but about a third way thru I noticed the belt flopping around like it was loose. Sure enough it was, I tightened it again...and again...and again. By the time I was done cutting the grass the belt looked like it had been on there 10 years and i was almost out of adjustment on the mule drive. The belt was thinner and badly frayed.

      Now when the first belt failed i took the deck off checked out the spindles, they were not loose no rough spots and i greased them. I also checked the mule pulleys, I didn't see any way to grease them but they spun nice. I pulled the pto hub off checked both bearings and greased them with lithium grease. Everything looked good!

      After the second belt was shot I decided to try and diagnose the problem. I can spin everything with my hand, with the belt on, it feels ok. But what i noticed was the pto belt as it comes off the engine side pulley of the pto hub the side of the belt rubs the side of the pulley on the pto. It rubs on the tall side or  the friction pad / clutch side. I stood up and looked down and saw the belt was running on a angle inwards towards the motor as it goes down the the v pulley which is closest to the motor on the mule drive.

      So I think this is the problem, it makes sense to me anyway that rubbing on the side of that belt would cause heat and would fray the belt, which is what I have. I just don't know how to adjust the mule to align the pulleys. Maybe its not the mule and the motor slide on the  on the mounts causing the mis-alignment.

      Any help would be much appreciated folks!
      Best Regards,
      Rick
