Milwaukee Lawn mower not self propelling
If your Milwaukee 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 that belt turns the drive pulleys that move the wheels. Next, check the drive pulley for wear or damage, then inspect the wheel assembly because worn wheel gears can keep the transmission from engaging the drive wheels. If the pulley on the transmission is spinning while the mower is running but the wheels still do not move, the transmission or transmission assembly has likely failed and will need to be replaced, since it is not repairable. A broken, binding, or misadjusted traction control cable is a less common cause, but it can also leave a self-propelled mower not pulling. If your mower drive wheels are not turning or you suspect a lawn mower drive belt problem or mower traction cable problem, inspect each part in that order. Enter your Milwaukee model number on RepairClinic.com to find the exact V-belt, drive pulley, wheel assembly, transmission, or traction control cable for your specific lawn mower.
01 - Milwaukee Lawn Mower V-Belt

02 - Milwaukee 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 - Milwaukee 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 - Milwaukee 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 - Milwaukee 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 - Milwaukee 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.
