Cyclone Mower

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.

These heavy duty shredders are designed for the most rugged working environments with reduced power consumption, outperforming equivalent-sized flail mowers in every way.

Its patented ‘blender’ double-chop 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 the toughest jobs.

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.

We run a flock of 500 sheep alongside a medium sized beef enterprise on the Isle of Arann in Scotland. Rushes are our biggest challenge so we were in the market for a flail mower but our dealer, Hamilton Brothers, sugges ...

Our Cyclone has been a great purchase because I can use it for mulching shrub as well as topping and general grassland maintenance and we can use a much smaller tractor now.

The mulching blade system on the cutter really chops everything up and shreds it up very fine. I've had several compliments from landowners on how the fields look after we got done mowing.
