The Ultra Rotary Blade is engineered for the professional turfgrass manager who is serious about achieving the highest quality of cut possible with a rotary mower. The Ultra Rotary Blade is manufactured from high chrome / nickel alloys, specifically heat treated and polished for maximum performance and longevity.

With a super thin profile, the Ultra Rotary Blade glides through grass and delivers a quality of cut comparable to most reel type mowers. The special alloy steel holds a sharp edge much longer than conventional rotary blades. When re-sharpening is necessary, just one to two passes along the cutting edge restores the blade to its original razor sharp edge.

Blade Spacers are required for some  models  (Sold Separately)

These replacement Height of Cut Spacers are CNC machined from cold rolled steel bar stock, and are much tougher than stock bushings. Clear zinc plated for corrosion resistance.
