Features:

The "GXV" series (highly professional) has been developed for heavy-duty work in construction, agriculture, generators, welding machines, etc., and is characterised by its durability and reliability.

The engine is SUPPLIED WITHOUT OIL.
Before starting it, read the instruction manual carefully.

The stainless steel housing can be defined as the only type of housing that is truly timeless.

Comparison with other types of housings:

- normal painted steel housing Generally sturdy but tends to rust over time due to the humidity of the grass; they also have a more limited sheet thickness

- aluminium housing:
Has a limited tendency to rust, but is much more delicate than stainless steel in the event of impact

- ABS housing:
They do not rust, but are by far the least sturdy due to the less consistent material. Widely used on electric lawn mowers, but also by many companies on petrol lawn mowers. Certainly the least reliable over time.

Thanks to the quick connector for the water hose, the housing can be washed quickly.

Steel front bumper that further protects the already sturdy housing.

Detail of the steel blade: professional "finned" blade equipped with special extension wings at both ends that generate a much more powerful air flow than traditional blades, improving both the collection function of the basket and the mulching system and all other systems.

The blade fitted is universal, suitable for performing the four functions of the lawn mower

Detail of the housing thickness: a full 2 mm. This makes it very resistant and not easily deformed by impact.

Rear-wheel drive (self-propelled).
Equipped with a sturdy belt drive with gearbox

Allows the operator to mow the lawn effortlessly, optimising the machine's traction and feed efficiency. 3 gears available, selectable from the convenient selector on the handlebar.

The high-wheel system provides incredible manoeuvrability. The wheels are mounted on ball bearings, which greatly extend their life.

The Ma.Ri.Na. Systems MX 57 SH 3V lawn mower has 5 cutting height adjustments available.

They range from a minimum of 20 mm to a maximum of 80 mm.

The centralised adjustment is incredibly quick and intuitive.

Simply operate the lever to raise the machine from a minimum of 20 mm to a maximum height of 80 mm.

Cutting system with bag collection:

The lawn mower is equipped with a large 85-litre canvas and plastic bag, which is very easy to remove and empty.

The lower part of the basket is made of plastic, which gives it sturdiness and steadiness, preventing the canvas from tearing when it comes into contact with the ground. The upper part is also reinforced with plastic.

A practical handle is located at the top of the bag to facilitate removal and emptying when full.

REAR DISCHARGE SYSTEM:

allows you to cut grass without using the grass collector, depositing it directly at the rear of the lawn mower.

Simply remove the grass collector and the rear discharge system will automatically start working.

MULCHING CUTTING SYSTEM:

for cutting grass without collecting it, pulverising it very finely before depositing it on the ground.

Instant conversion: simply remove the grass collector, insert the supplied mulching plug and lower the rear deflector to enable the mulching system.

WHAT IS MULCHING:
a cutting system that shreds the grass clipping and then releases it back onto the lawn, pulverised so small that it almost looks as if it has been collected. This eliminates the problem of disposal (reducing effort and drastically shortening the time taken to mow) and, as it decomposes, it will subsequently turn into nutrient for the lawn itself and water (grass is 80% water), thus ensuring a perfectly balanced biological cycle. However, it is worth remembering that, in order to ensure the absolute efficiency of the system, the lawn must still be watered and the grass clipping at least once a week.

SIDE DISCHARGE SYSTEM:

for cutting grass without collecting it (even grass that is slightly taller than normal, given the high disposal capacity of the side deflector)

Leaving the mulching plug in place, so that it blocks the rear grass discharge, simply lift the black side cover on the housing and insert the supplied side deflector with a simple movement.

Professional aluminium handle with micrometric height adjustment system.

The handlebar is coated for maximum comfort of use.

Simple and intuitive controls located on the handlebar.

Blade engagement lever (lever in front of the handlebar)

Self-propulsion activation lever (lever behind the handlebar)

Blade rotation speed adjustment

Forward gear settings: 3 gears available

Adjustments available for the lawn mower:

Cutting height adjustment

Handlebar tilt adjustment:

The handlebar is equipped with a micrometric device for adjusting the height of the handle, which allows quick height adjustment or closure via two quick-release levers on the sides (open and close).

The lawn mower is designed and intended exclusively for cutting grass in garden areas (and not on other types of terrain). The surface must be level, free from irregularities, stones, or other solid objects, and covered with maintained lawn grass (therefore, not uncultivated or spontaneous vegetation). Grass should be cut regularly and must not be allowed to grow beyond 25–30 cm, as most lawn mowers are no longer capable of cutting at this height. Slopes exceeding 15% (equivalent to 9°) must be avoided, except when using 4x4 models.

For heavier-duty tasks involving spontaneous vegetation, grass taller than the above-mentioned limits, or rougher surfaces than a garden, please consider alternative product categories such as Petrol Flail Mowers or Brush Cutters.

Furthermore, grass must only be cut when both the lawn and the underlying soil are completely dry. Mowing should be carried out exclusively in dry weather, well away from periods of rain or irrigation, and preferably in the afternoon, when the grass is no longer affected by morning humidity. Wet grass tends to bend under the blades, which reduces cutting efficiency, increases the risk of clogging inside the deck, and subjects the engine to excessive strain.
