Depends on teeth fitted. This unit available either with swinging hammers or 'Y' flails depending on type of foliage being cut. The hammers are for mulching and the flails are for grass cutting, however both will work for either application, just not as efficiently.

@@mattgage5669 ....see that's totally the information I needed to make an informed choice for an implement. So the teeth on the mulchers do swing out of the way if an immovable object is "struck" ....nice...so it's all in changing the teeth between hammers(T) and flails(Y) regardless of if it's a flail mower or Mulcher

Hi Rob, yes on this Mulcher the teeth swing out of the way, 'swinging hammers'. Fixed hammer mulchers are also available but have a much heavier duty rotor and normally are a more open front design to allow larger material to enter. These are normally referred to as a 'forestry mulcher'. On this unit, the swinging hammers and the Y flails are interchangeable on the same rotor.
