Marina Systems GRINDER ZERO SK self-propelled mulching lawn mower

The Marina Systems GRINDER ZERO SK lawn mower is designed for professional use and for the most demanding consumers who need a machine suitable for gardens with narrow and hard-to-reach spaces.

It stands out from the competitors thanks to its high power and reliability, all thanks to the Kohler HD775 engine.

The heavy-duty transmission is provided with an aluminium housing and bronze gears.

Compared to other competitors, the GRINDER ZERO SK is provided 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.
  • Possibility to adjust the height of the front pivoting wheels
  • Possibility to lock/unlock the steering of the right pivoting wheel.

Thanks to its housing and the blade optimised for performing the mulching cutting system, this machine will ensure the highest performance for a perfect lawn care.

Traction drive with speed variator from 2 Km/h to 3.2 Km/h.

It is equipped with forward speed variator and blade speed controller.

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

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.

Two 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.

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 is suitable for surfaces up to 1800 s.q. m.

Speed variator

The machine is equipped with a speed variator.

A great advantage compared with the other only self-propelled lawn mowers.

Thanks to the handy dash-mounted lever, the speed variator allows you to adjust the forwarding speed and use the minimum traction in non-rectilinear paths or in curves and to carry out a bit slower manoeuvres.

It also allows using the lawn mower at its max. working speed even when the grass is regularly cut, not too high or not too thick. It is also possible to use it at max. operating speed even on regularly cut and not too high or thick grass and to operate faster on even lawn without many obstacles.

Very appreciated by professionals who are faced with different situations or for those who have a particularly rough garden with obstacles.

WARNING! The speed variator must be activated only while the machine is moving, in order to avoid malfunctions and/or damages.

Front pivoting wheel, extreme manoeuvrability

The great advantage of this lawn mower is represented by its 2 pivoting wheels configuration.

Extremely easy steering!

This solution ensures a truly extraordinary mobility as it allows you to turn the mower in every direction without any effort.

This lawn mower is ideal for soils with many obstacles, such as lawns with trees or flowerbeds. The lightness of the steer and the wide manoeuvrability enable you to work accurately with the minimal effort.

The 2 front pivoting wheels can be adjusted in 5 different height positions by means of the proper lever:

By means the control on the handlebar, it is possible to lock/unlock the steering of the right pivoting wheel, so that to keep the same driving direction.

Double steel blade and steel housing

52 cm double Grinder blade, sturdy and specifically designed for the mulching cutting system: heavy-duty "finned" blade with special extended wings at both ends that creates a much more powerful air flow than standard blades.

Extremely sturdy 2 mm reinforced housing for high durability, featuring a folded underside that makes it virtually indestructible.

Focus on the protective cone on the drive shaft to insulate and prevent damages of any kind.

Focus on the cover that protects the transmission from bumps.

from 20 mm to 70 mm. Thanks to the centralised cutting height adjustment system, the cutting height can be adjusted by means a single lever according to the needs:

Specific wheel “scraper” for cleaning automatically and effortlessly the wheels.
