1250 Eating Tiller Belts

[awilson]

I have a #2 Tiller mounted on a 1250 that I purchased about 5 years ago. I put new OEM belts on at that time. I used the tiller for 2 seasons and it broke the main belt on the third season, probably put less than 20 hours on the belts. I didn't use it for a couple years and am trying to figure out why it's breaking the belts so I can use it again. OEM belt isn't available anymore so I purchased a 17/32" x 146.5" Gates Blade Runner belt and installed it. I placed a piece of cardboard under the mule drive and started the PTO. I immediately can see small rubber bits flying off the belt and dropping onto the cardboard. I cannot figure out why, the belt isn't rubbing mule drive pulleys are positioned straight back to the angle gearbox. Here are some pictures of what I'm working with. Notice the front edge of the belt on the PTO pulley is wearing down. I put some mule drive pulleys on that are narrower than the ones in the picture, belt rides flush with the edges of them. That didn't make a difference.

The OEM belt is 7/16 x 145 1/2 yours is too wide.

I wouldn't say 1/2" is too wide since Digger is selling a 1/2" to fit this application. Seems to me that there could be something else going on besides an incorrect belt. Why did the last belt I had on, an OEM last less than 20 hours of use before wearing down and breaking in the same way this one is doing.

Is the mule drive bent or not square to the front of the tractor? How worn are the Frankenstein bolts?You should replace the missing snubber and the other old one with new, then see if there is an improvement.

Note that the info Digger posted is a kit that includes with the belt, two wider pulleys to allow use of the wider belt...

I’m aware that it’s a belt and pulley kit. I have tried 2 widths of idler pulleys with the same results. Mule drive looks square, I have tried another one I had just so see what happened and had the same results. Frankenstein Bolts? Are you referring to the bolts sticking out of the side of the frame that the mule drive slides into?

yes.
