Nominal Power: 15 HP
The correct term would be "Commercial” Power, meaning the standard definition officially used until a few years ago by all well-known engine manufacturers.

* This figure is the one that is most widely used and publicised in the main sales channels, even if it is higher than the real power of the engine.

Actual power: 11.3 HP
It refers to the actual power output at the drive shaft. This is the figure listed as official in the engine manufacturer's instruction manual or technical data.

* This is a figure that can vary for the same engine model depending on the rpm the equipment manufacturer has decided to have the engine applied

The engine is SUPPLIED WITHOUT OIL.
Read the instruction manual carefully before start-up.

WARNING: using it at less than maximum revs, in addition to not efficiently shredding branches and failing to chop larger diameters, can lead to a whole series of anomalies
- lowering of revolutions or shutting down of the engine during use;
- rapid deterioration of the drive belts between the engine and rotor;
- damage to the centrifugal clutch of which, if the engine is not at maximum revs, does not expand completely, causing it to wear out until it burns and needs to be replaced;

Track unit: sturdy and large. Better than the average flail mower of the same size on the market. The perfect balance ensures the distribution of loads and a perfect grip on the ground.

Tracks: top-quality tracks are used. Thanks to their tread width and profile, they guarantee perfect grip and stability on all types of soil. Made of special reinforced rubber with high grip, they are able to cope with all kinds of surfaces.
