ABSTRACT:
An adjustable axle support system for a lawn mower for supporting the whe and blade housing at a preselectable elevation in accordance with a desired cutting height of the grass cutting blade which is rotatable in a horizontal plane within the blade housing of the mower. The system includes brackets fixed to the opposite ends of the front and rear sections of the blade housing with the axles received in vertical slots formed in the brackets. Axle bearings are slidable on the axles for receipt in enlarged openings formed along the slots in the brackets. The axle bearings are biased into the selected enlarged openings by coil compression springs received about the axles. Adjustment of the height of the blade housing and in turn the cutting blade is achieved simply by retracting the bearings along the axles against the bias of the springs and moving the axles along the slots in the brackets into the desired elevation and then placing the bearings into the appropriate enlarged openings along the bracket slots.
