Durability, reliability and efficiency are the key elements of the award-winning Cyclone Mower / Rotary shredder. From traditional pasture topping to clearing crop stubble, these machines are equally at home in set-aside, forestry margin management, and sensitive environmental scrubland control.

Its patented ‘blender’ double-chop blade system ensures all material is thoroughly pulverised and evenly distributed across the entire width of the machine, speeding up the decomposition process so nutrients return back to the soil. The rotary blade system requires 25% less HP than a flail mower, slashing at least 25% off upfront fuel costs. The Major Cyclone is the mower of choice for every job.

High-performance Strenx™ 700 MC structural steel makes these mowers strong, while Hardox® 450 abrasion-resistant steel for the undersole discs ensures a long wear life. Combined with hot-dip galvanisation to EN ISO 1461:2009 specifications, the Cyclone is guaranteed impact tough.

“The Major Cyclone is very competitively priced, uses much less fuel and leaves an excellent striped finish. It handles virtually everything we throw at it. Even the heavy, tufted marsh grass is no challenge.”
