So the replacement drive belt i got is an automotive belt, cost me like $40 and it is about 1 inch shorter.  I wasn't sure because the old belt was shot so i figured it may ahve stretched.  AFter installing the new belt i'm having a probem now where the clutch will not engage or stop the machine. Basically when you put it in gear it goes and the only way to stop is to slam it back down into neutral.  I double checking the belt routing and I did all of that correctly.  Could it be that the belt itself is not right or what do you guys think?   It mows and runs fine but it's kind of a pain not being able to stop it or slow it down by pressing in on the clutch.

 

 

thanks in advance guys.

Do you have the original part number?

Automotive belts are not like most lawn and Garden belts, especially if they are a special size.....

For some reason, Sears/Craftsman use an odd-half size belt. I think they expect you to buy from their parts department.

1 inch shorter is alot! The last one I replaced was only 1/2 inch different, but as you described, would not disengage with the clutch. It took the boy running around the yard almost a hour before it stretched enough to work correctly. That same belt is still on the machine after 3 summers mowing 3 acres. If you are unable to find the correct belt or one closer to the correct size, I would suggest finding an idler pulley that is a little smaller. Good luck.

Auto belts can cause problems when using on a drive of a mower. You need a "fractional drive belt" or OEM belt to replace. Sounds like between it being too short and being a standard auto belt, it;s grabbing pulleys and not disengaging.

Sounds like you got a Gold mower like me too, mine is 15 Hp.

yeah it's the gold mower.  thanks for the tips guys.  this belt does not have quite as much of a V as the other belt, but it is a very good quality belt so i plan to keep using it.  I had one on a previous mower for years that held up much better than a craftsman or generic belt.  The clutch has already started engaging in 4th and 5th gear so I think once i get a good mow in it will start working properly.

what kind of problems can it cause?  i've run them on my murrays for years, they always seemed to last longer.

I had a problem with the belt having too much grip, and not letting the clutch disengage. The same problem you are describing. I swapped out the brand new Gates belt for an actual mower drive belt from TSC and that took care of it.

Automotive belts are not designed for clutching drives.....

well since it's working for now i'm gonna stick it out and keep using it.  Do you thin it will cause any harm to use it?  My yard is huge so not having the clutch is ok, we've got 2 other mowers that we use for around the house and stuff, but having to mow 3 acres the clutch not disengaging.  really isn't forcing me to stop using it.  I will plan to get a belt in the future but right now have a john deere 214 project that is taking the main focus.

I had one on my ST16, it was on it when I got tractor, I've used it for 3 years, but it has worn to the point it wouldn't disengage the pulleys and I kept grinding gears. I replaced with a Kevlar belt designed for use on mower drives and it works like a charm now.

If it's working use it until you have to replace again
