A very common question out there is, “Why am I replacing belts every year?” First you should not be having to replace belts every year or more in one year.

Since having purchased it in 2015 we have an average belt of once (maybe twice per year as we have a large yard). This mowing season alone we have replaced the belt 5 times, three of which have been in the past week. We went to Lowe’s last night and picked up, yet another new belt. Put it on today, I started to mow, short grass I just mowed last week, as I didn’t want it to get too tall or have the possibility that it would flood again (we live in Missouri, and no we have not been cutting tall grass with the mower, we do that with our farm tractor or a push mower and then go over it with the riding mower.). We have taken the deck off of the lawn tractor once but I’m afraid that I am going to have to replace all the deck pullies as the belts show MASSIVE signs of UNEVEN wear.

Any idea as to what is causing this? Goldwing electrical troubleshooting manual. Were either of you able to find out anything concerning your own issues with your Troy-bilt’s belt issues?

Cube cadet / MTD mowers all the same has an issue with there pulleys not lining up and they know that, they haven’t addressed the issue or tried to fix the problem and we just keep on buying them. I had to use washers to line up my pulleys on my cub cadet after that I had no more problems. Longer the gape between each pulley the more play and vibration you get in the belt causing it to break down. Closer the pulleys less vibration you have in the belt. What I did was I just added an extra pulley in the longer spaces which tightens up the belt causing less break down in the belt and also reduces the vibration in the belt.

This is only partly related: A little over a month ago my Craftsman 917.203830 T2400 stopped moving, so I sent it to a shop. They said the transaxle drive belt had slipped, broken the transaxle fan, etc. And replaced the parts for almost $300.

Last weekend it happened again. They said the same thing happened and wanted to do the same repair.

I said no, because I can replace the parts myself for $60 or so. The main question is, why is this happening? I’m not going to replace these two parts every month.

Anyone have any idea why the belt would slip, break, and break the fan on one of these repeatedly? Hi all, some good tips are already posted here, but i would like to add one more solution to tearing up belts. Look under, at the pulley attached to the motor itselfit could be there. I checked mine after going through belts continuously and found that, that pulley was the problem. I undone the engine mount bolts and placed washers (spacers) between the engine and the chassis to make the pulley line up when ALL belts were in the WORKING positionI havent changed the belts on anything for over 18 months now. Even though these pressed tin ride on mowers are from a factory somewhere, the chassis could be just a little twisted after assembly Hope this is of some help to your problems, doing this certainly fixed mine.
