Green Machine Lawn mower not self propelling
If your Green Machine 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 rotate the drive pulleys and turn 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 frequent reason a self-propelled mower is not pulling. If the transmission pulley spins while the mower is running but the drive wheels do not move, the transmission or transmission assembly has likely failed and will need to be replaced. A mower traction cable can also cause a lawn mower drive belt problem if the cable is broken, binding, or out of adjustment, though that is less common. If your Green Machine self-propelled mower is not pulling or the mower drive wheels are not turning, enter your model number on RepairClinic.com to find the exact V-belt, drive pulley, wheel assembly, transmission, transmission assembly, or traction control cable for your specific mower.
01 - Green Machine 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 - Green Machine 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 - Green Machine 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.
Top Solution
04 - Green Machine 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 - Green Machine 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 - Green Machine 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.
