    I have a 48" Scag belt driven WB that has gone through 4 belts on the right side this season. It doesn't really wear them out, it just stretches them to the point that the right side won't pull. I've tried treating it with belt dressing, and that seems to help for a little while but it will do it again soon after. Has anyone had this problem? Or perhaps some idea of why it is doing this? Any input would be helpful. I love this machine, it leaves a beautiful line but gets really frustrating having to replace belts or constantly stay on the left brake.

    is there perhaps a belt tensioner that is turned too tight?

    4 belts in one year:confused: Those drive belts should last for more than 700-1000 hours. I'm not sure how many hours you put on in a year but that's a lot of belts. How are your bearings on the drive system, it sounds like something is really putting a lot of pressure on the belts to stretch them like that.

    The tensioner's on both sides are set the same, or as close as I can get them actually, so I don't think there is that much difference on the right side. The drive system is still in good shape, I am not sure how many hours I have on the mower, there's no meter, but i would guesstimate less than 700. The mower is a 2002 model. I noticed the other day, that almost all of my turns are to the right, (i am right handed) but surely that wouldn't cause such a problem?!

    is the tension on the brake perhaps turned on too tight?

    also check to see whether or not the pulleys are aligned.

    I would also check the belt size to make sure that its right

    Hmmmmm........ I hadn't thought about the brake? If the brakes tensioner were too tight, would it cause it to pull to the right?

    yes, it could cause it. If the brake was too tight on the right and not the left it can cause it to pull.

    Let me ask you this...does your right hand constantly hurt after use? If it does, than this could be your problem

    I have found on the belt driven mowers that we own, every operator is different on the tension for the break. Some like it loose and some like it tight.

    My hands don't bother me after use. Unless I have had to fight it all day, if I am out mowing and don't have time/part to change the belt, then my LEFT hand hurts....LOL.
