I have a 36" lesco and the right side belt slips. If you push it, it will go but then eventually start slipping. Lesco does not do repairs here. They looked at it and had me replace the spring along with the belt. I have still can't get it to work. So yesterday I attached a bungie cord to the top to help pull down more on that whatever you call it still slips. I don't get it. I also tried cleaning that round thing that comes out from the shaft that the belt goes around. I also took of the arm going to it just to make sure it was getting all the way down. That didn't work either and the brak is not on.

Any suggestions. Maybe this belt is the wrong size just by a little bit?

How old is your mower? The problem may be the jack shaft pulley being worn, this is the double pulley off to both sides of the transmission they tend to wear and make the belt drop low in the grove and since this belt actually grabs on the sides and not in the middle this is probably causing your slip I would change both sides at the same time the item#is 021969 hope this helps

Yeah, that is what another shop told me. But I called a guy who works on Leso and he said that it was most likely that my wheel was locking up. Well I can push it fine. The guy who does repair on Lesco stuff also said there is now way it could be that pulley. I don't see how it could be either but it is an old mower. Not sure how old but runs and works great.

On a side note I just called Lesco to get a price on that part number you gave me. I called right at 4:30pm. He said can you hold. I held for 5 min called back and it said they were closed. He didn't want to mess with it I guess as they close at 4:30.

Thanks for the info.

The wheel locking up? Then why will it grab if you push tension onto the belt?
Those pulleys do and will wear I just replaced two sets on two scag 48" walk behind mowers this week, and have done this same repair on lots of Lesco's. The wheel bearing may have failed on that wheel but I have replaced less wheel bearing then side drive pulleys in my time. Well good luck

Well then I am going to replace that pulley. What do they run?

I had a snapper that had this kind of problem...you can get a little more grip out of that driving pulley by taking a pointy punch and making indentions all along the side.. I assume the pulleys are very clean? And sometimes the belts just don't drive....we replaced Snapper belts with Scag and got a little more drive. In the end with the dang Snapper it never worked well.

look at the brakes and see of one is closed because that could cause your belt to keep running with the wheel stopped

It ended up being those pulleys. I replace both of them. But man they were hard to get off.

Had the same problem. Replaced both jackshaft pulleys and the walkbehind runs and drives like new. Mine is 25 years old and I purchased it new. Couldnt find lesco parts but the scag pulleys are the same. Order 2 stens replacements off amazon for $40 each.
