Ariens Lawn mower not self propelling
If your Ariens 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 on the engine crankshaft. If it is damaged, the transmission may not engage the wheel assembly. Worn gears in the wheel assembly are another likely cause, since the transmission drive gear needs those gears to pull the mower forward. If the pulley is spinning but the wheels still do not turn, the transmission or transmission assembly has likely failed and will need to be replaced. A broken, sticking, or misadjusted traction control cable can also keep an Ariens self-propelled mower from pulling, though that is less common. If your lawn mower is not self-propelling, your self-propelled mower is not pulling, or the mower drive wheels are not turning, inspect these parts in that order. Enter your model number on RepairClinic.com to find the exact Ariens V-belt, drive pulley, wheel assembly, transmission, or traction control cable for your mower.
01 - Ariens 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 - Ariens 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.

03 - Ariens 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 - Ariens 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.
Highly Likely
05 - Ariens 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 - Ariens 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.
