Lawn mower support structure
First Claim
1. In a lawn mower having a motor, a cutting blade rotated by said motor about a substantially vertical axis, a chassis surrounding said blade, a motor support, and a support structure mounted between said motor and the chassis and including vibration insulation means, the improvement comprising;
- said vibration insulating means including a plurality of elongated blocks of resilient material, the blocks being placed with their longitudinal axis in the radial direction so that when they are acted upon by a tangential force are deformed more than when they are acted upon by a radial force, and separate means for joining the chassis and motor support whereby a limited tangential movement is permitted between said motor support and chassis while preventing the separation of said chassis and motor support, said separate means comprising sleeves having flanges that are fixed to said chassis.

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.
