ABSTRACT:
This invention relates to a lawn mower comprising a motor, preferably of the combustion engine type, rotating a knife about a vertical axis, a chassis surrounding said knife and a support structure between the motor and the chassis comprising vibration insulating means. The vibration insulating means comprise several elongated blocks (22) of elastic material the blocks being placed with their longitudinal axis in the radial direction so that they when being acted on by tangential forces (B) are deformed more than when they are acted on by radial forces (C) the support structure joining the chassis (16) and a motor support (10) to each other by separate means (28,29) allowing a limited tangetial movement between the motor support and the chassis and preventing separation of the motor support and the chassis.
