Start the tape measure at the hole you use and measure to the end of the belt, where it meets the buckle. Belts are measured in inches and you should round to the nearest inch. If you measure 36 inches, you will want to purchase a size 36 belt.
An easy way to determine belt size is to simply “add 2″ to your off-the-rack trouser size. For example, if you wear a 36” waist trouser, then a 38-belt size will be a safe bet. Most will find this simple formula works best for pants worn at a traditional height–close to the natural waistline.

Riding mower model numbers are found by flipping the seat forward. The model number is printed on the left side of the Product Identification Label, attached to the underside of the seat, and starts with the letters, “CM”.
To determine your belt size, measure your waist through your belt loops using a tape measure. The resulting number of inches or centimeters is your belt size. From the middle hole of your new belt, measure out the number of inches of your belt size. This is the point where you will cut the belt.
Continue to measure around the inside of the lawnmower deck until you record the distance between the last spindle pulley and Spindle Pulley 1. Add up the measurements to determine the total distance around the spindle pulleys. This is the size of the mower deck belt you need.
