Marina Systems GRINDER 52 VK lawn mower

The Marina Systems GRINDER 52 VK lawn mower is designed for the most demanding professional users, extremely performing and powerful, intended and optimised for mulching for ensuring perfect lawn care.

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

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.

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

The GRINDER 52 VK is a powerful, reliable and very versatile lawn mower, driven by a powerful 5 Hp 173 cc KOHOLER HD775 low profile engine equipped with heavy-duty transmission and aluminium housing.

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.

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

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.

This lawn mower is suitable for surfaces up to 1800 s.q. m.

Kohler HD775 engine

The Kohler HD775 engine guarantees high performances and it is suitable for works that require high reliability and durability, thanks to its remarkable 173 cc.

Features Values
Engine type: 4-Stroke, single cylinder
Cylinder type: Cast Iron
Cubic Capacity: 173 cm³
Power supply: Petrol
Starting: Recoil starting
Recommended working area: 1750 s.q. m.
Max rpm 3600 rpm

Nominal Power: 6.0 Hp
The correct term would be "Commercial” Power, meaning the standard definition used until a few years ago by all well-known engine manufacturers.

* This technical feature is the one indicated in the main sales channels, even if it is higher than the real power of the engine.

Rated power: 5 Hp (at 3600 rpm)
It refers to the real power of the engine. This is the power indicated as official in the manual or in the technical data of the engine manufacturer.

* This technical feature may vary from a an engine model to another according to the rotation speed provided by the manufacturer.

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 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 to use 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 regulator must be activated only while the machine is moving, in order to avoid malfunctions and/or damages.

Double mulching blade and steel housing

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

The mounted blades are made of hardened steel, and are suitable for performing high-quality mulching. The special blade fins creates an air vortex which helps shredding the freshly cut grass even finer. It also ensures excellent performance in tall, damp grass.

Standard front bull bar to highly protect the machine.

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.

Protective cone on the drive shaft to prevent damage of any kind.

Housing thickness: 2.0 mm

Centralised cutting height adjustment

The Ma.Ri.Na. Systems lawn mower is equipped with 5 cutting height adjustments, from 20 mm to 70 mm.

It is equipped with galvanised wheels, certainly much more resistant than standard wheels.

The centralised cutting height adjustment is incredibly fast and intuitive.

Simply operate the proper lever to lift the machine.

Specific wheel “scraper” for cleaning automatically the wheels.

Controls and adjustments

Coated handlebar for optimal working comfort.

Easy and user-friendly controls placed on the handlebar.

Blade engagement lever (white lever in front of the handlebar)

Self-propelling engagement lever (black lever behind the handlebar)

Rotation speed adjustment: the knob allows adjusting the blade rotation speed.
