Yard-Man Lawn mower not self propelling
If your Yard-Man lawn mower is not self propelling, the problem is usually in the drive system, not the engine. The most common cause is a worn or broken V-belt, since that belt turns the drive pulleys that power the wheels. Next, check the drive pulley itself. If it is damaged, the transmission may not engage the wheel assembly. Worn gears in the wheel assembly are another frequent reason a self-propelled mower is not pulling or the mower drive wheels are not turning. If those parts look good, inspect the transmission or transmission assembly while the mower is running. If the transmission pulley spins but the wheels do not move, the transmission has failed and will need to be replaced. A less common cause is a mower traction cable problem, where the traction control cable is broken, sticking, or out of adjustment. If your Yard-Man lawn mower is not self propelling, enter your model number on RepairClinic.com to find the exact V-belt, drive pulley, wheel assembly, transmission, transmission assembly, or traction control cable that fits your mower.
01 - Yard-Man V-Belt
The V-belt rotates the drive pulleys to drive the lawn mower wheels. If the V-belt is worn out or broken, the lawn mower wheels won’t turn. Inspect the V-belt for damage. If the V-belt is defective, replace it.

02 - Yard-Man Drive Pulley
The drive pulley connects to the engine crankshaft. If the drive pulley is worn out or broken, the transmission won’t be able to engage the wheel assembly. Inspect the drive pulley for damage. If the drive pulley is defective, replace it.
Top Solution
03 - Yard-Man Wheel Assembly
The wheel assembly has a set of gears which engage with the transmission drive gear. If the gears are worn out, the transmission won’t be able to engage the wheel assembly. If the gears are worn out, replace the wheel assembly.

04 - Yard-Man Transmission
The transmission is powered by the drive belt, and the drive belt connects to the engine crankshaft. When the drive belt powers the transmission, the lawn mower wheels turn. To determine if the transmission is defective, observe the transmission while the lawn mower is running. If the transmission pulley is spinning, but the lawn mower wheels don’t turn, this indicates that the transmission is defective. The transmission is not repairable—if the transmission is defective, you must replace it.

05 - Yard-Man Transmission Assembly
The transmission is powered by the drive belt, and the drive belt connects to the engine crankshaft. When the drive belt powers the transmission, the lawn mower wheels turn. To determine if the transmission is defective, check the transmission while the lawn mower is running. If the transmission pulley is spinning, but the lawn mower wheels don’t turn, this indicates that the transmission is defective. The transmission is not repairable—if the transmission is defective, you must replace it.
Highly Likely
06 - Yard-Man Traction Control Cable
The traction control cable might be broken or misadjusted. Check the traction control cable to determine if it moves freely. If the control cable does not move freely, try squirting a small amount of oil into the end of the cable to lubricate it. If lubricating the traction control cable is not effective, replace it.
