Rated Power: 6 HP
The correct term would be "Commercial” Power, meaning the classic standard of definition of power officially used until a few years ago by all leading engine manufacturers.

* This figure is even more widespread and advertised in the leading commercial channels, although it is a matter that it is higher than the actual power.

Effective power: 4.7 HP (a rotation speed of 3600 rpm)
It corresponds to the real power expressed motor shaft. This is the power indicated as official in the manual or in the technical data of the motor’s manufacturer.

* This technical data may vary for the same engine model depending on the rotational speed supplied by the engine applied to the equipment.

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; To carry out a bit slower maneuvers.

To easily leverage the maximum speed in case of regularly cut, not very high or not too consistent grass. To carry out a straight cutting in absence of particular obstacles, speeding the work.

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

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

Double Blade included: Grass Collection + Mulching

Most of the lawn mowers which offer different functions, such as grass collection and mulching, has a multipurpose blade that offers discrete performances without obtaining excellent results in either type of mowing.

This lawn mower is equipped with 2 specific professional blades:

  • A Professional finned blade
  • A Specific blade for mulching

They guarantee the best result for every type of mowing.

  • The professional high load finned blade allows an optimal filling of the grass collector and ensures the best possible mowing for the grass collection and the side discharge. Thanks to this blade it will be easy to cut the grass even a little wet, high or thick.
  • The specific blade for mulching ensures the best result for this type of mowing, at the same level of the best specific lawn mowers for mulching.

Steel Blade and Stainless Steel Housing

The stainless steel housing guarantees high durability over time and it is the most sturdy among other housings.

Comparison with other housings:

- Common painted steel housing Generally sturdy but tends to rust over time due to the moisture of the grass; it also has a less thickness plate.

- Aluminium housing:
It has a low tendency to rust but it is much more delicate than a stainless steel housing under impact.

- ABS housing:
It doesn’t rust but it is by far the least sturdy because of less compact material. Very used on electric lawn mowers, but many companies use it also on petrol ones. Certainly less reliable over time.

Quick washing joint for the water pipe with which it is possible to wash the housing.

Front steel bumper which further protects the housing.

Focus on the 51 cm steel blade: "Finned” professional blade equipped with special extended wings at both ends that generate a much more powerful airflow compared to conventional blades, improving the grass collection mowing, mulching and all of the mowing systems.

Universal hardened steel blade, suitable for the 4 mowing options.

Rear-wheel Drive and High-wheel System

Self-propulsion device (Rear traction).
Equipped with a sturdy belt transmission with reduction gear box

which allows the operator to conduct the grass cutting operation without effort, optimizing the traction of the machine and the feed efficiency.

The high-wheel system guarantees an incredible handling. The wheels are mounted on sturdy ball bearings which make them greatly long-lasting.

Rear wheels diameter: 210mm

Front wheels diameter: 280mm

Focus on the Wheels made of galvanized metal

Focus on the intermediate belt transmission (motor / traction) perfectlyclosed and protected by the proper black carter.

Centralised Cutting Height Adjustment

The Ma.Ri.Na. Systems MX 55 lawn mower has 5 cutting height adjustments options,

from 20 mm to 80 mm.

The centralized cutting height adjustment is incredibly fast and intuitive.

Simply use the proper lever to lift the machine from a minimum of 20 mm to a maximum of 80 mm height.

Mowing Operations: Grass Collection Mowing


The lawnmower is equipped with a 60 L hybrid grass collector, very easy to remove and empty.

The lower part is made of plastic, which gives strength and sturdiness, avoiding the canvas to tear if in contact with the lawn. Practical handle placed at the top of the collector to make it easy its drawing and emptying when full.

Full bag indicator system: The red switch lifts when the grass collector has reached the maximum capacity.

Mowing Operations: Rear Discharge


This system allows mowing grass without using the grass collector,discharging the grass clippings directly from the back of the lawn mower.

Just remove the grass collector and the rear exhaust system will function automatically.

Mowing Operations: 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.

To convert the machine for the mulching cut, insert the mulching plug supplied and lower the rear flap.

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.

Mowing Operations: Side Discharge


This system allows mowing grass without collecting the clippings inside the grass collector (it is also possible to collect grass a bit higher than normal, due to the high disposal capacity of the side exhaust deflector).

Leaving the mulching plug inserted, in order not to occlude the rear discharge of the grass, simply lift the black carter on the side of the body and insert the side deflector supplied with a simple gesture.
