Self-Propelled Lawn Mower Jerks The Pull Cord Handle Out of My Hand

This is a serious problem and can cause injury to your hand and arm! So you want to stop pulling on that pull cord immediately and have this problem inspected to determine what is causing it.

If the lawn mower has been repaired recently, the repair could have been done incorrectly. If you hit something with the lawn mower, then it has affected the timing of the engines firing and that is why it is ripping the cord out of your hand.

I fully understand this problem because I have had a pull cord rip from my hand and gouge in other hand that was on the handle bars.

Another thing that can cause this is a loose lawn mower blade. As the blade rotates, it will cause the firing to be off a few degrees and bam…that pull cord rips right out of your hand!

So as you can see, this is a serious problem that needs to be addressed. The problem will not go away or fix itself, so get your lawn mower into a shop and have it repaired correctly. Visit our Locations page for a shop near you.

Lawn Mower Repair Tips

My Lawn Mower Jerks the Pull Cord Out of My Hand

This is a dangerous condition and can easily cut your hand or worse, break a bone in it. Do not continue to try and pull start the lawn mower until you have it checked out by a lawn mower repair professional.

Now you are probably wondering why this happens in the first place right? Well, most of the time it happens because you have hit something with the blade or someone has been working on the engine internals and did not set the timing up right on the cam.

When you hit something or have a blade strike as it is called in the industry, it will cause the shear key in the flywheel to move or “shear” as it is designed to do. When this flywheel key shears, it causes the timing of the ignition firing to be off a number of degrees. When the spark plug fires at the wrong time, it will cause the piston to move violently in the downward motion and the pull cord is still trying to move the piston in the upward position.

The result is the force you feel when the pull cord is whipped out of your hand and the handle slams into the engine cover.

So it is wise to get your lawn mower checked out by a professional that can diagnose the problem and repair it so you have a safe to operate mower once again.
