Marina Systems GRINDER G52 S Lawn Mower

The Ma.Ri.Na Systems Grinder G52 S petrol lawn mower is designed for the most demanding customers who need an highly performing, reliable and professional machine, specifically for mulching, so as to perfectly take care of their green space.

The housing is entirely made of steel and it is 2 mm thick.

This cutting tool guarantees the highest cutting performances for a healthy, green lawn and a professional mulching cutting system, even for tall grass, with the same mowing frequency of a conventional lawn mower with grass collector.

No chemical fertilization needed. Also ideal for crushing leaves without raking.

Compared to other competitors, the grinder G52 S is equipped with:

  • Double grinder blade: It creates a vortex of air that pushes the grass clippings towards the cutting edge of the blade and then pushes them up away, resulting in a very fine shredding (similar to a centrifugal effect).
  • Crankshaft protective cone, to prevent any kind of damage.
  • The transmission is raised and covered by a plastic body, which makes the transmission more resistant.
  • The lower part of the body is folded, so as to make the body virtually unbreakable.

Rear-wheel drive self-propelled lawn mower, less effort, reduced time, improved efficiency and results.

Grinder G52 S is a powerful, reliable and very versatile lawn mower. It is equipped with a powerful Yamaha MA190 engine, with 5 hp of rated power and low profile with high-resistant transmission, aluminum box and bronze gears to optimize the size and durability of the engine.

Its 52 cm cutting width can also be height adjusted through a centralized lever in 5 different positions, from 20 mm to 70 mm.

Centralized height adjustment system with a single lever.

4 235 mm large wheels made of galvanized metal with double sealed ball bearings and moisture-resistant, which provide a professional cut also on non perfectly flat lawns. They are mounted on ball bearings to make moving the lawn mower as easily as possible.

Front bull bar supplied, to protect the machine.

This lawn mower is suitable for surfaces up to 1900 s.q. m.
