Burning PTO deck belt.

I just put a new PTO deck belt on my Bobcat. When I disengage the blades, they stop. The blade brake is right on and works well. However, the engine to deck belt (PTO) chirps and burns. I've adjusted it to no end and it just won't stop doing it. It's the correct belt. Any advise?

Is this a factory (OEM) replacement belt per your unit model and serial number ?

Look at the inside (V groove) of the engine/deck drive pulley and make sure there's no film of rubber from the old belt present on the faces, This will cause the new belt to grab. If you find nothing post the model and serial numbers.....

Make sure you have the belt on the right side of the belt guides if any.

Belt is within the two belt guides. I'll get the model number off it tomorrow. The pulley is pretty clean. I even adjusted the tensioner all the down to make it as slack as possible when in the "disengaged" position and it still wants to grab the belt.

Possible dealer gave you incorrect part.

Maybe, but the belt that it replaced was from Agri Supply. I simply measured the old broken one and bought one from AS just using that measurement. That one did it too, but it got me through the rest of last season. I went to the dealer to get the right one figuring that would fix it, but it didn't and the two are nearly identical in length.

I asked this question for a reason, And now we'll see why.....

After reading the above I did some look'n around without your model number, I found ALL walkbehind 48" decks both floating and fixed require the same belt.

Now, The fact that you bought belts by measuring length doesn't mean your getting the correct belt. Even going to your dealer doesn't mean he sold you the correct belt, Dealers can't stock every OEM belt so they stock cheaper aftermarket belts, Most have a full wall in increments by the inch since standard generic belts only come that size unless it's a OEM "replacement" belt which will be the exact length and make up as the OEM.


Here's where I believe your issue lies;

The aftermarket belts you've bought are wrapped belts as that's standard unless it's labeled as OEM "replacement".....

Wrapped belt;




Your machine requires a raw edge belt;




Installing a wrapped belt in place of a raw edge belt or vise-versa can cause the issue your having, I've seen it first hand many times.....

The OEM belt you need for your machine is part # 2722160, It's also available in a aftermarket "OEM replacement", It's 5/8"x 73 3/8" long and is raw edged..... Once this belt is installed engage the deck with engine off and adjust the two flat bar belt guides under the engine, The flat part of the guide should be parallel with the belt and 1/8 to 3/16" from touching the belt.

With this done your belt chirp'n/skip'n/flop'n issue should be history......

Uh no, I just looked that belt up. That is used on the newer machines with Electric clutches....no way for the belt to "catch" with an electric clutch... Definitely not the correct belt for this machine.

What are the model numbers of the machine you are working on? You may have 2 tags on the machine. One on the back half of the machine and one on the mower deck. Get all the numbers and post them up so we can find you the correct belt number.

Might be a 38442 but could be others depending on model numbers
