Marina Systems GRINDER 4X4 SKW Mulching Lawn Mower

The Marina Systems GRINDER 4X4 SKW mulching lawn mower is an advanced lawn care solution, ideal for those wishing to achieve a perfect garden without the use of chemical fertilizers. Thanks to its mowing technology, this mower is able to pulverize the leaves, eliminating the need for raking.

The body and Mulching blade are designed to leave a fine residue that serves as a natural fertilizer, nourishing and keeping the lawn in perfect condition. This model is especially suitable for those who need to care for large areas and deal with difficult ground, including steep slopes.

The four 235 mm large galvanised metal wheels, equipped with double sealed bearings, guarantee moisture resistance and professional mowing on uneven surfaces. The ball bearings facilitate the handling of the mower as much as possible, making it manoeuvrable even in the most demanding situations.

Designed to meet the needs of the most demanding professional, the GRINDER 4X4 SKW is a high performance and powerful lawn mower. Equipped with a 4.5 Hp, 179 cc Kawasaki FJ180V Engine, it offers power and reliability, as well as a professional aluminium housing drive.

The central cutting height adjustment system allows the mower to be easily adapted to the lawn's needs via a lever with five different settings, ranging from 20 to 70 mm.

All-wheel drive (2WD / 4WD) allows the GRINDER 4x4 SKWto easily tackle uneven surfaces and steep sloping areas, making it extremely versatile.

Main features:

  • Double grinder blade: It generates an air swirl that raises grass fragments onto the blade cutting edge, chopping them finely and ensuring optimal mulching effect.
  • Crankshaft protective cone: Protects the engine from damage.
  • Raised and covered transmission: The plastic housing protects the transmission, improving durability and strength.
  • Folded lower housing: It adds further strength to the structure, making it nearly unbreakable.
  • Standard front bull bar protects the mower during use.

With a 52 cm cutting width and an all-wheel drive that reduces effort and working time, the GRINDER 4X4 SKW is the ideal choice for surfaces up to 2900 s.q.m., ensuring flawless results and an evergreen, healthy lawn.

Double Mulching Blade and Steel Housing

The extremely sturdy shell is reinforced with a 2 mm layer, ensuring high durability and structural strength. The lower part of the shell is folded, making it practically unbreakable and able to withstand even the harshest circumstances.

The machine is fitted with a front bull bar as standard, offering additional protection against collisions 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, and are suitable for performing 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.
