Weed Eater Lawn mower not self propelling
If your Weed Eater 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 frequent reason a self-propelled mower is not pulling, since the transmission drive gear will not be able to grab the wheels. If the pulley is spinning but the mower drive wheels are not turning, the transmission or transmission assembly has likely failed and will need to be replaced, since these parts are not repairable. A less common cause of a lawn mower drive belt problem is a broken or misadjusted traction control cable, which can sometimes be freed up with a little oil. For the right fix, enter your Weed Eater model number on RepairClinic.com to find the exact V-belt, drive pulley, wheel assembly, transmission, or traction control cable that fits your mower.

02 - Weed Eater 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 - Weed Eater 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 - Weed Eater 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.
Highly Likely
05 - Weed Eater 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 - Weed Eater 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.
