Description

Marina Systems GRINDER 4X4 SKW mulching lawn mower

Mulching Marina Systems GRINDER 4X4 SKW lawn mower:

No chemical fertilisation required. Also great for shredding leaves without having to rake them before.

Thanks to its housing and the mulching cutting system, the lawn mower will leave the grass clippings finely shredded on the lawn leaving it well cared and nourished.

It is specifically designed for those who need to take care even of large-sized areas with uneven terrain or slopes.

Four 235 mm large galvanised metal wheels featuring double sealed bearings, which are moist resistant and allow a professional cut even on not perfectly levelled lawns. They are mounted on ball bearings for ensuring to the lawn mower the maximum ease of movement.

It is designed for the most demanding professional users and it is extremely performing and powerful.

The GRINDER 4X4 SKW is a powerful, reliable and very versatile lawn mower, driven by a powerful 5 Hp 179 cc Kawasaki FJ 180 V low profile engine equipped with heavy-duty transmission and aluminium housing.

Centralised cutting height adjustment system: possibility to adjust the cutting height by means of a single lever.

This lawn mower is equipped with:

  • Double grinder blade: it creates 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)
  • Protective cone on the drive shaft to prevent damage of any kind.
  • Raised transmission covered by a plastic housing, which makes the transmission sturdier.
  • The lower part of the housing is folded down, making it virtually indestructible.

The blade ensures the best mowing performance for a healthy, green lawn, professional mulching even for tall grass combined with the same cutting frequency as a standard lawn mower equipped with grass collector.

This lawn mower model is provided with 52 cm cutting width. It can be also adjusted through a centralised lever in 5 different positions, from 20 mm to 70 mm.

Standard front bull bar to highly protect the machine.

The rear-wheel drive ensures effortless and quick mowing operations combined with higher-quality results.
