There’s nothing quite as frustrating as pulling the starter cord on your trusty Craftsman mower, hearing the engine roar to life, and then realizing it’s not going to do the heavy pushing for you. When the self-propelling feature fails, your easy mowing day suddenly becomes a strenuous workout. That reliable workhorse now feels like a heavy, stubborn piece of metal you have to manually guide across your yard.
Before you consider a costly replacement or a trip to the repair shop, it’s worth knowing that most issues preventing the drive system from working are surprisingly simple to diagnose and fix yourself. With a systematic approach, you can often get your mower back to doing the pushing for you. This guide will walk you through the essential steps for Craftsman Lawn Mower Not Self-Propelling, Troubleshooting and Maintenance, helping you identify the common culprits and restore your mower’s go-power.
Start With the Simple Stuff: The Drive Cable
The most common reason for a self-propelled mower to stop working is a problem with the drive control cable. This is the cable that activates when you squeeze the bail lever against the handle. Over time, this cable can stretch or its housing can come loose, meaning you’re not fully engaging the drive mechanism even when the lever is pulled. To check this, look at where the cable attaches to the transmission on the mower’s deck. With the engine off, have a helper squeeze the drive control lever. If the cable isn’t pulling a lever on the transmission all the way, it will need adjustment, which is usually done via a small clamp or nut.
Checking the Drive Belt for Wear and Tear
If the cable is moving correctly, the next item to inspect is the drive belt. This V-shaped belt is the crucial link that transfers power from the engine to the wheels. Belts can become stretched, glazed, cracked, or even snap completely. To inspect it, you’ll typically need to tip the mower on its side (always with the air filter facing up to prevent oil leaks). Look for any signs of damage on the belt. If it looks worn or feels loose, it’s likely the source of your problem. Replacing a worn drive belt is a common repair and a new belt is an inexpensive part.
Craftsman Lawn Mower Not Self-Propelling, Troubleshooting and Maintenance
Sometimes the issue isn’t with the cable or belt, but with the wheels themselves. Many self-propelled mowers have an adjustable height setting on each wheel. If one wheel is set significantly higher than the others, it can prevent the drive system from engaging properly because that wheel isn’t making sufficient contact with the ground. Ensure all wheels are set to the same cutting height. It’s also a good idea to check that no debris, like wrapped-around grass or a stray stick, is jamming the wheel or the axle, preventing it from turning freely.
Keeping Your Mower’s Drive System Healthy
Regular maintenance is the key to preventing these issues from popping up in the first season. After each use, take a few minutes to clean off any caked-on grass from the underside of the deck and around the wheels and axles. Periodically check the drive cable for smooth operation and look for early signs of belt wear. Storing your mower in a dry place also helps protect the metal components and the belt from premature deterioration caused by moisture.
By methodically checking the drive cable, inspecting the belt, and ensuring the wheels are clear and properly adjusted, you can usually solve the problem of a non-propelling mower yourself. These simple checks can save you time and money, getting you and your Craftsman mower back to a smooth, easy mow in no time.
