Overview
This replacement drive belt is sized for Ariens zero-turn mower applications that call for OEM part number 07225600 or 7225600. The belt measures 1/2 inch wide by 73 inches long, so the main fitment checks are the OEM part number, the printed model number on the mower, and the belt routing shown in the owner’s manual.
Belts are high-wear items that stretch, crack, and glaze over time. A worn belt can cause slipping, squealing, poor drive engagement, and uneven cut quality. Replacing it with a correctly sized aftermarket belt restores consistent power transfer when the pulleys, guides, and tensioner are in good condition.

Common questions
Q: Will this 1/2” x 73” belt fit my Ariens Zenith 60, model 991163, in place of OEM part 07225600/7225600?
Yes, this belt is made as a replacement for Ariens part 07225600 (also written 7225600) and is listed for the Zenith 60” model 991163. It is also compatible with Ariens APEX 60, APEX52, and APEX48 models including 991159 and 991158, as long as your original belt size matches 1/2” x 73”.
Q: My old drive belt from the APEX 52 is worn and glazed—does this replacement have the correct width and length for proper drive performance?
For the listed Ariens APEX and Zenith zero-turn models, this replacement uses the correct 1/2-inch width and 73-inch length to match the original drive belt specification. A properly sized belt helps maintain correct tension, reduces slipping, and prevents premature wear on the pulleys and idlers.
Q: Do I need to do anything special when installing this 73-inch V-belt on an Ariens zero-turn mower?
Before installing, inspect the idler pulleys, belt guides, and tensioner for wear or seized bearings, because a new belt can fail quickly if those parts are damaged. Route the belt exactly like the original, make sure it sits fully in each pulley groove, and recheck tension and alignment after a short test run.
