Experienced gardeners share their insights in answering this question :
Do not just buy a belt that is “close” to your size belt. the size of the belt is not always a standard size, there is a width as well as a length and also a power rating , that is critical in belt replacement. you must have the model number of the Mower unit “not the engine model” to get the correct belt. OEM belts are made to certain specifications to withstand certain actions of the mower and the wrong size belt could result in a dangerous situation of the blade not stopping or engaging sporadically, or if it is a transmission belt , the mower may not go forward or not stop moving which again is dangerous.

The drive belt on a Craftsman riding mower is usually around 104 inches long. It is designed to be durable and long-lasting, able to withstand the rigors of mowing.
If a belt is too short, it can increase belt tension. This increases sideloads on the idler pulley and components like the alternator and power steering pump. If the belt is too long, it could slip and wear out the belt prematurely. Both conditions can also damage the tensioner.
Drive Belt Sizes

All V belts should be measured across the depth of the belt and the top, thick section. To measure a V belt correctly, this means that you would measure the widest part of the belt (the thickest section), and then measure from the widest to the narrowest parts of the belt.

I’m having trouble replaceing the motion drive belt on my LT1000 lawn tractor. The mowing deck is off, the old drive belt is off. I can’t get the belt around the transaxle pully. Any suggestions?
ANSWER : Often there is a keeper on the back of the pulley, and the belt must go inside the keeper. Get an inspection mirror up in there to look if necessary. Start by putting the belt on the transaxle pulley, then on the PTO pulley, then on the idler, last have someone sit on the mower and depress the clutch pedal while you put the belt over that pulley.
