Lawn Mower Repair Tips

Lawn Mower is Vibrating Excessively

You can really tell on a push mower if something is out of whack. When you start up the mower on a concrete surface and it wants to jump around rather than sitting in one place. This is a sign that something is out of balance. You could have hit something with the lawn mower blade and bent either the blade or the crankshaft on the mower. You could also have a cracked blade or a piece missing from it.

You could also have a loose lawn mower blade that is causing this vibration. It is something that is rotating and is not in proper alignment that causes it to vibrate excessively. This rotation will cause it to jump from side to side and can be dangerous if the mower gets out of control.

This vibration situation should be checked out as soon as possible to see what is causing it and a repair recommendation. A small engine repair shop can identify what this issue is and find a solution for you so that your lawn mower will be safe to operate once again.

Self-Propelled Lawn Mower Vibrates Excessively

When you start your self-propelled lawn mower, you usually start it in the concrete or asphalt driveway. While you start it up and it is running at top speed, you seem to notice that it is vibrating more than usual. Did you hit something such as a rock, root or concrete?

Excessive vibration is a sign of a bent crankshaft, loose engine mounts or a bent lawn mower blade. You could also have a cracked mower deck that is causing the problem.

These items should be inspected by a competent lawn mower repair shop to find out which of these is causing the problem. It will not get any better if the crankshaft is bent and will begin to loosen bolts and nuts with the vibration.

It is not recommended that a bent crankshaft be straightened. Straightening it can weaken the shaft.
