MULCHING CUTTING SYSTEM
This system allows cutting grass without catching it inside the collector, and crushing the clippings into a fine powder before dropping them on the lawn.

As it is specifically designed to perform this cutting system, this lawn mower provides a much higher quality product than the one provided by lawn mowers performing more than one cutting system.

WHAT IS MULCHING: this grass mowing system allows crushing grass clippings and dropping them on the ground. The resulting grass particles are so small, they will be barely noticeable on the lawn. This eliminates the problem of its disposal (reducing any effort and shortening the time-saving). Moreover, grass clippings will break down into nutrients and water for the lawn (grass is 80% water) and will thus ensure a perfectly balanced biological cycle. However, it is worth remembering that, to ensure the greatest mulching results, the lawn should be irrigated and the grass needs cutting at least once a week.

CONVERSION TO THE SIDE DISCHARGE: simply unscrew the side plug and enter the proper deflector to operate with the side discharge cutting system.

51 cm real cutting width

The blade is made of universal hardened steel, suitable for performing a high quality mulching cutting system. The special blade fins creates an air vortex which helps shredding the freshly cut grass even finer. It can perform excellent cutting operations even in tall, damp grass.

Double cutting power
The special finned blade ensures:

- a high-quality mulching, creating an air vortex that forces grass fragments to fall back onto the blade cutting edge and be thrown back up, resulting in very fine shredding (similar to a centrifugal effect)

- high-quality cutting results, thanks to the hardness of the steel and to the special sharpening, which is truly superior.

The steel housing guarantees high sturdiness and a long service life.

Focus on the quick washing joint.

‎This lawn mower is equipped with 6 cutting height adjustments, from 25 mm to 70 mm.

The centralised cutting height adjustment is incredibly fast and intuitive.
