Simplicity Lawn mower not self propelling
If your Simplicity 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, since a damaged pulley can keep power from reaching the transmission and wheel assembly. Worn gears in the wheel assembly are another common reason a self-propelled mower is not pulling, especially if the mower drive wheels are not turning even though the engine runs normally. If those parts look good, inspect the transmission or transmission assembly. When the transmission pulley spins but the wheels do not move, the transmission has failed and will need to be replaced. A misadjusted or sticking traction control cable can also cause a mower traction cable problem, though it is less common. For a Simplicity lawn mower not self propelling issue, entering your model number on RepairClinic.com is the fastest way to find the exact V-belt, drive pulley, wheel assembly, transmission, or traction control cable that fits your mower.
01 - Simplicity Lawn Mower 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 - Simplicity Lawn Mower 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 - Simplicity Lawn Mower 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 - Simplicity 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 - Simplicity 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. 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 - Simplicity 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.
