Abstract: Spiked wheels or roller means are utilized on the lawn mower in lieu of the customary rubber tired support wheels to prevent mashing or flattening the grass prior to cutting. The usual unsightly tracks produced by conventional wheels are eliminated. The spiked wheels or roller means penetrate the standing grass with negligible disturbance while furnishing adequate support for the mower. The spiked wheels or rollers may be mounted directly ahead of the cutter blades to allow "zero clearance trimming" when mowing edges of the lawn.
