I have a 36" ride on mower. I've replaced the blade drive belt three times and I'm still have problems with the belt burning out while I'm driving the mower (not actually mowing). It seems to be burning out at the pulley attached to the engine. It is the same belt listed on the parts listing. I'm not looking forward to purchasing another mower. Does anyone have a good solution to fix this problem? Thanks

Since you mentioned "48-inch riding mower" let's assume your question is about the mower deck and not the overall mower or its main drive belt (if manual shift-on-the-fly model). If the belt burns that means it is running but slipping against something; or that the drive sheave us turning against an impeded belt. In the first case the belt will be burned along its length; in the second the burning will be occuring in one location(s) along the belt. In any case of belt slippage, check first that all tensioners (springs) are properly in place and not broken or fatigued and in need of replacement. The only other thing would be resistance to belt running, such as:
blade blockage; blade rotor resistance from lack of grease or ruined bearing in need of replacment; grass clogging on deck underside or under blade drive pulley on deck top side; a pully sheave out of round; an obstacle between belt and sheave that is preventing free turn of sheave and belt run; misrouted belt; an overstretched belt that cannot be sufficiently tensioned. Inspect and correct or replace as needed.
My idea is not about the belts, but is about the deck. If the tensioning mechanism on the deck is getting stuck in an intermittant position than the belt may be just tight enough to turn blades while slipping through the pulleys, this may cause enough friction to start melting your belts. If this is the case you will have to remove your mower deck and see what is preventing the mechanism from functioning properly.
You say you checked everything. I would remove the deck and belt and physically make sure both blades spin freely. Then I'd install the belt and check again, it sounds as though each component works fine alone but when in conjunction with other parts something is binding. Good luck
Here's what I have run into many times when all adjustments are correct. If it is not an original equipment belt after market belts vary in length. Which means most times they are usually a bit short. In this case you have two outs. One is to live with it which is not always safe and two get an original equipment belt from a dealer or the manufacture.Good luck.
