How to replace a lawn mower drive cable
This DIY lawn mower repair guide gives step-by-step instructions for replacing a lawn mower drive cable. The drive cable connects the handle drive control lever to the transmission and engages the transmission to move the mower across the grass when you pull the drive lever up. Replace the drive cable with a manufacturer-approved lawn mower part if it's broken or frozen up inside the sheath and your lawn mower won’t move.
Use this basic procedure to replace the drive cable on common Craftsman, Toro, MTD, Husqvarna, Troybilt, Ariens and Poulan walk-behind lawn mowers.
A drive cable problem is just one reason the wheels of a lawn mower won't drive forward. To learn how to diagnose a lawn mower drive problem, see Lawn Mower Won't Move Troubleshooting Video: Motion Drive Failure.
