Abstract
This disclosure relates to a sound absorbing arrangement for a power lawnmower in which sound absorbing material is provided within the body of the lawnmower to reduce noise by attenuating resonance caused by the lawnmower motor. In addition to reducing noise, the sound absorbing material imparts structural rigidity to the lawnmower body or housing, and also may be used to define air passages within the lawnmower body for use in cooling the motor.
