Troybilt Drive Belt Seems Too Loose

I have a Troybilt Super Bronco model #13BX60TG766 riding lawn mower. I removed the deck to replace a new deck belt that was broken. I installed the new belt (#754-04045) and when I put it under the mower and attached it to the engine pulley it seemed too loose even when the blades were engaged. I called
Troybilt to make sure the replacement belt was correct. She verified that it was the right replacement belt. I checked and rechecked to see if I made a mistake on installing the belt. I can't find one.Very frustrating to say the least. Do I have to readjust one of the pulleys? I'm afraid to engage the blade for fear something will happen to this new $30 belt. In the meantime my husband has been using the push mower for our 2 1/4 acres of property. Not a happy camper. Any advice would be great. Thanks. Cheri

Do you have an owner's manual that shows the belt routing? That would be a good check. Is there possibly an idler pulley on a movable arm that has lost a spring? Check drawings in the manual to make sure. If you don't have a manual, I would bet that you can download one from the TB web site.

Hope this helps.

Hi
Yes I have the manual but there is not too much information plus pictures are bad and directions are very sketchy. What is the worst scenario if I engage the blades and the belt isn't tight enough? Thanks. Cheri

Ms. Cheri,


If the blades are engaged with the belt loose the unit will only burn it up.

Maybe the below will help with proper belt routing, Also make sure the belt is on the proper side of any belt guides.





Good Luck

Troy-Bilt Drive Belt

Hope someone can help me. I have a Troy-Bilt Bronco which several weeks ago, 'threw' the drive belt. Everything I've found so far only gives a routing diagram for the blade belts. Even the owner's manual. Can't find a routing diagram for the drive (transmission) belt anywhere. Neighbor told me that this is a recurring problem with Troy-Bilt products, especially the Bronco.
Can someone PLEASE provide me with a routing diagram for the drive belt? My 1/2 acre grass is getting rather out of control!
Best,
Mike

Your unit was built by MTD and I haven't seen any problems other than normal wear with this drive system.

Here is the diagram for the unit model posted by Ms. Cheri since you didn't post a model number.

The rear idler pulley goes to the inside of the rear belt.






Good Luck

I have a troybilt superbronco 13ax60tg766. Replaced a broken spring but blade belt is loose. Diagrams in manual aren't very good. Looking for a better diagram or picture to make sure of the placement of spring.
