If you’re after a good all-round mower, you can’t go far wrong than by choosing a flail mower. This can do the job of a topper with more versatility. Like a topper, it will cut long grass and woody material, but it’s also suitable for short grass such as lawns leaving a good finish if used regularly.

A flail mower leaves the grass cuttings short which soon mulch down and provide a great natural fertilizer. A flail mower can handle the rough, uneven ground and they’re highly maneuverable in tight spaces. As they are more compact than the topper mower, they’re also easier to store in between cuts.

The flail mower gets its name from the use of flails attached to its horizontal rotor. The rows of flails are staggered to provide a complete cut. The rotor is parallel to the axle of the tractor. As the rotor rotates, centrifugal force pushes the flails outward. If a flail strikes an immovable object, it simply bounces off. Siromer flail mower rotors are electronically balanced. Flail mowers cut the grass very finely and then roll it into the ground.


The Siromer light-duty flail mowers use a Y flail and the heavy-duty mowers use a hammer flail. The Y blades are more of a knife and less of a mulcher and they leave a very clean cut and a much tidier-looking finish. Hammer flails are much wider and heavier and can cut much thicker material.


The Siromer heavy-duty flail mowers 1.45m and over have an option of being fitted with a belt tensioner and opening back. The opening back allows the grass to be evenly distributed and prevents it from clogging up inside the mower. The cutting height can be set by adjusting the skids and the roller. Siromer flail mowers are semi-offset and the heavy-duty flail mowers over 1.45m have an option of hydraulic side shift. The hydraulic side shift mowers require a double-acting spool valve on the tractor to operate the side shift. These hydraulic side shift mowers can be moved 6 inches left or right, ideal for mowing close to hedges and around trees.
