  If your Husqvarna Lawn Mower engine loses power, it could be due to several reasons. You might be cutting too much grass or going too fast, so try raising the cutting height and reducing speed.

A build-up of grass, leaves, or trash under the mower can also cause this, so clean the underside of the mower housing.
