Belt Burning out

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

Check for bad bearing in clutch immediately, Remove belt, try and turn the clutch pulley if it is hard to turn or feels rough, replace the bearing in the clutch. If you do not replace bearing immediately you will be buying a $300.00 clutch very soon. I know from experience. You possibly have been hearing a loud unusual roar from engine area for awhile and wondered where it was coming from. As these bearing will usually squall a cry for awhile before they die.

Remember the belt rule, V of the belt goes in V pulleys.Flat pulleys that are stationary or move get the back of the belt. You can figure it out. Its not rocket science. Remember at some point there has to be a tensioner,usually gets the back of the belt if its a flat pulley. U may have to remove the spring and then reattach the spring after the belt is routed.

Belts wont move

I would check to make sure that that the belt isn't pinched somewhere around the pulleys. See if they are movable with mower disengaged and off. If they are hard to move, they most likely have pressure keeping them from moving.
They would create a burning smell even though they are not moving. The main pulley while engaged does rotate and if the belt is touching but not moving, it will rub enough to make the odor.

My MTD riding lawnmower is burning thru the new belts I just purchased.The new belts are 954-0371A which replaces 754-0371A. The old style belt lasted 5 years. Even before engaging the clutch, the belt...

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.

How do I change the drive belt on a 7021r mower? The drive will move the mower on pavement but not on the grass

First, you need to make sure you have the right tools for the job. You'll need a wrench, work gloves, mower blade clamp, drain pan and fresh fuel. Check your owner's manual for the correct belt to your specific lawn mower. Belts that are not specifically designed for your mower will not fit properly and may wear down prematurely. Next, remove the spark plug wire. This is a safety precaution to prevent the mower from accidentally starting.
Now you can remove the screws that secure the drive cover to the mower deck. Once you've taken off the drive cover, loosen the screw that holds the belt tension spring to the transmission. As the screw is loosened, tension on the belt is released allowing you to remove the belt off of the front transmission pulley.
At this point you'll need to turn your mower on its side to take off the mower blade. Be sure to use a work glove to protect your hand when removing the mower blade. You can use a lawn mower blade clamp over the blade to secure it. Unscrew the bolt to remove the blade and then the engine baffle. Once the pulley unit is exposed, you can remove the entire drive belt. Insert the new drive belt and place one end on the rear pulley and re-attach the engine baffle. Then, place the mower blade back (making sure it's facing the correct way with bottom of the blade facing the ground) and tighten the bolt. Remove the clamp and return the mower to its upright position so you can place the other end of the belt to the front pulley. Remember to tighten the screw to the tension spring.
Put the front drive cover back on, tighten the screw that secures the cover to the deck and reconnect the spark plug wire. Add new fuel to your mower and you're done!

Hello. REmove the deck from your mower so you can easily get at the belt and the blade. Make a drawing of how the belt is installed so you can install the new one the same way, loosen the idler pulley and remove the belt. Generally you have to remove a couple of parts to get the old belt off in one piece and get the new one on. You will need a set of socket wrences. To replace the blade use a block of wood to hold the old blade stationary and a large socket wrench to loosen the nut holding the blade in place.

My blades wont engage and just hear click sound?

No permanent solution, but you probably can get by once by "riding" the clutch engagement lever - pushing it only part way forward and holding onto it.

I have replaced the drive belt linking to the two blades on my Rally ride-on lawn mower (92cm 5 speed 11.5 hp) and they are now cutting effectively. The problem I have is that the blades are still driven...

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.
