Marina Systems GRINDER 4x4 SH PRO - Trailed Petrol Lawn Mower - Honda GXV 160 Engine

The Marina Systems GRINDER 4x4 SH PRO petrol lawn mower is a high quality product, ideal for the most demanding professional consumers. This mower is equipped with a Honda GXV 160, a low emission 163cc engine with throttle, ensuring powerful and reliable performance. All-wheel drive (2WD / 4WD) allows the GRINDER 4x4 SH PRO to easily tackle uneven surfaces and steep sloping areas, making it extremely versatile.

The 2 mm thick steel body gives the mower strength and durability, while the 52 cm cutting width and height adjustable via a central lever in 5 setting, from 20 to 70 mm, ensure a precise and customised cut.

The dual grinder blade system creates an air swirl that finely shreds the grass, facilitating professional mulching which allows tall grass to be cut as often as with a conventional collection mower, reducing the need for chemical fertilization and raking.

The design includes a raised transmission covered by a durable plastic housing, protecting the internal components and increasing the product's service life. The four large 235 mm galvanized metal wheels with double sealed bearings guarantee excellent mobility on different types of surfaces. Additionally, the standard-supplied front bull bar provides additional protection and stability during use.

These features make the Marina Systems GRINDER 4x4 SH PRO petrol mower an excellent choice for those looking for a powerful, reliable and versatile lawn mower.

Features:

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

* This data is still more widespread and advertised in the main commercial sales channels, although it is an increased figure compared to the actual power.

Effective Power: 4.3 HP
Corresponds to the actual power expressed at the crankshaft. It is the one indicated as official in the engine manufacturer's manual or technical data.

* This is data that can vary for the same engine model depending on the rotation speed that the equipment manufacturer has decided to have the applied engine deliver.

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

The extremely strong housing is reinforced with a 2 mm layer, ensuring high durability and structural strength. The lower part of the housing is folded, making it nearly unbreakable and able to withstand even the toughest conditions.

The machine is fitted with a standard-supplied front bull bar, offering additional protection against impacts or obstacles, preserving the mower's integrity.

The cutting system includes a 52 cm professional double grinder blade, specifically designed for mulching. This 'finned' blade features extended wings at both ends, generating a much more powerful airflow than conventional blades, further improving cutting quality and grinding capacity.

The fitted blades are made of hardened steel, perfectly suited for high-quality mulching. The special 'fins' with which they are equipped, create an air swirl that helps to shred the freshly cut grass more finely. This design optimizes performance even in tall and damp grass, ensuring a smooth and precise cut.

To protect the engine from damage, the mower is equipped with a protective cone on the crankshaft, which isolates and prevents any damage.
