Snapper Lawn mower not self propelling

If your Snapper 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 the belt turns the drive pulleys that power the wheels. Next, check the drive pulley itself. If it is damaged or worn, the transmission may not engage the wheel assembly. Worn gears in the wheel assembly are another common reason a self-propelled mower is not pulling even though the mower runs normally. If those parts look good, watch the transmission while the mower is running. If the transmission pulley spins but the drive wheels do not move, the transmission or transmission assembly has failed and will need to be replaced. A mower traction cable problem can also keep a Snapper self-propelled mower from moving, especially if the traction control cable is broken, stiff, or out of adjustment. For a lawn mower not self-propelling complaint, enter your model number on RepairClinic.com to find the exact Snapper V-belt, drive pulley, wheel assembly, transmission, or traction control cable that fits your mower.

04 - Snapper 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.

06 - Snapper 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.
