Hello all new here,
I am working on a ‘98 TG1860G, somewhat new to this tractor as I don’t use it myself. For the last 3000 hrs of its life my Father-In-Law runs it to mow my grass on the farm here.
My question is about the drive belt from the engine to the rear end. The bearings went out on the stack of pullys in front of the rear axle and shredded the belt last week. The old man brought it to me to fix. I ended up taking off the pulley and replaced the bearings but I never had a chance to look at the belt routing as it shredded and he cleaned it out. It seems my google searching abilities are worthless as I can’t find any info.

There is a idler pulley under the pan where your feet sit, does the belt go around both sides or one or the other? There is a small piece of “bar stock” welded to the idler bracket on the right side of the pulley with not enough room to get the belt between it and the pulley. Do I need to drop that pulley and re install with the belt on it?
Is there a diagram accessible anywhere? I know he seems pretty basic but my brain must be tired these days

Thanks!

Pierce1984, you need a snow blower for that machine? I have one made just for it with mounting hardware. It's like brand new. It needs to be relocated to a whiter climate!!

Hey there! I know it has been years but do you remember how this belt went? This is a long shot but I put a new belt on after removing the pulley system because it was to tight of a gap to go over the pulleys and I thought I had installed it correctly BUT with in an hour the belt was shredded again. I wish I could have snapped a picture of the first one but now I am in this same predicament as you from years ago.

This might help you.
This is going to help a bunch when I put the deck back on!

The belt I am looking for help on is rear belt that orangekuby posted ending in 2010.png. I had to have put that thing on wrong for it to shred as fast as it did

I think your local dealer would be able to provide the required diagrams. You may have to get to the service department to get them.

That is where I would start if they are close enough. You might try Coleman’s or Messicks if your dealer is not close.
