Cogged Belt VS Regular Belt

[GBertolet]

I have a lawn tractor made by Noma # 36115300. The stacked drive pulley is worn somewhat, and I cannot find a replacement. PN #30377. The belt slips when traversing a steep hill, or when pulling my TracVac leaf machine. No more adjustment left on the idler pulley. A new belt only improves things for a short period. It takes a 1/2 X 82 belt. Would switching to a cogged belt improve the grip on the pulley?

A cogged belt probably won't help. Cogged v-belts are intended to improve belt life when the belt has to wrap a small pulley...I don't believe they are able to transfer any more power than a solid v-belt. If it were my machine, I would try getting a 1" shorter belt to work, or getting a wider (possibly 5/8") belt.

I'd try a kelvar belt. I'll message you a couple of places that I have had good luck with for getting belts.

A lot of times a belt will slip when the V groves in the pulleys wear and turn into U groves. If the belt bottoms out in the groove, a wider belt will only be a temporary fix.

A Vee belt works because when the belt goes around the pulley groove the belt width becomes compressed and belt "swells" inside the groove . FWIW you can google vee belts to find width's , depth length etc .When i refurbed my old Oliver crawler a few years back the original part number for the 3/4" wide fan belt had been superceded and it took me three times from e-bay to find the correct one .
BTW you could try belt dressing but it would only be a temporary fix .
