Yard Machines Lawn mower not self propelling
If your Yard Machines 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 that can no longer turn the drive pulleys and move the wheels. Next, check the drive pulley itself. If it is cracked, worn, or damaged, the transmission may not engage the wheel assembly. Another likely cause is a worn wheel assembly, where the internal gears no longer mesh with the transmission drive gear. If the pulley is spinning while the mower is running but the wheels still do not move, the transmission or transmission assembly has likely failed and will need to be replaced, since it is not repairable. A less common issue is a mower traction cable problem, where the traction control cable is broken, sticking, or out of adjustment. For a self-propelled mower not pulling, enter your model number on RepairClinic.com to find the exact Yard Machines V-belt, drive pulley, wheel assembly, transmission, or traction control cable that fits your mower.

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 Machines Lawn Mower 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 Machines Lawn Mower 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.

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 Machines Lawn Mower 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.
