In this post we will look at what exactly a flail rotor is as well as how you can maximise the lifespan of your flail mower.

What is a flail rotor?

A flail rotor is essentially a rotating drum which has a number of elements attached to it. For example: these ‘flail elements’ could be blades for cutting grass. A mower which incorporates a flail rotor is typically well suited to heavier duty mowing tasks, such as those on large areas of land, like fields, orchards and greens.

What causes damage to flail mower rotors?

Many agricultural operators use heavy duty horizontal drum rotors for mowing or mulching. These flail rotors are subject to a lot of abuse during use due to unexpected debris. These include things like stones and rocks, which damage the flails. Bending them out of shape, snapping and loosening lugs.

As a ‘quick fix’, you can weld these lugs back on. However without dynamic balancing for the flail rotor itself, you will begin to notice the following problems:

  • Vibrations
  • Premature wear
  • Failure of components
  • Unsafe operation
