The drive belt on a Yard-Man riding tractor should be checked often for wear, breaks, and damage. Replace the belt at the sign of damage so that the tractor runs properly.
When changing the belt, you should always park the tractor on a flat, level surface and set the parking brake. Also, remove the spark plug wire from the spark plug to prevent the tractor from starting. Lower the deck to the lowest setting, remove the hex bolts next to the engine pulley, unhook the belt from the pulley, and remove the deck hanger links. Next, raise the deck control lever to the disengage position and remove the deck. You now have access to remove the belt, but make sure you write down how the belt goes around the pulley. Install the new belt around the pulleys starting with the pulley on the far right, when the belt is completely on in the correct pattern it will have a snug fit. Slide the deck back, lower the control lever back to its lowest setting and connect the deck hanger links. Attach the drive belt to the engine pulley, tighten the hex bolts into the deck, and raise the deck lever back to your cutting level preference.
The tag that has the model and serial number of your Yard-Man riding tractor can be found under the seat.
NOTE: if you need a part for the small engine in your Yard-Man lawn tractor, there will be a separate model/serial number for the engine. Here are the small engines that are available in your Yard-Man tractor. Visit the page of the engine you have to find out where the model/serial number is located for your small engine model:
