This not only helps reduce waste but also provides essential nutrients to the lawn, improving its overall health and appearance.
Starting the mower is simple and reliable with the easy-start recoil cord. This feature ensures that the engine can be quickly and efficiently started, even after periods of storage.

The foundation of the GRIN HM46A is its strong steel frame, which provides exceptional durability and stability.

One of the standout features of the GRIN HM46A is its anti-vibration quick regulator.

The steel wheels contribute to the mower’s overall stability, allowing for smooth navigation around obstacles and providing a reliable grip as you work through your lawn.
All the GRIN lawn mowers are designed, produced and assembled with the highest quality standards: the 3 mm thick steel frame and mowing deck, the engine protection cone for accidental impact, the professional tractions, the steel wheels, the centralized mowing height adjustment, the foldable handlebar are just some of the strengths.
This means that a GRIN mower can mow more grass and for a longer period, without getting overloaded. Therefore, GRIN performs much better in medium-tall grass than a conventional mulching system.
The GRIN mowing system consists of a patented blade with a particular shape and made of a special material. The blade is assembled with a patented helix disc in a specific position inside the mowing deck. These two components, combined with the shape of the mowing deck, create a vortex with centrifugal effect, which keeps the grass suspended in air for a long time to be pulverised in fine particles.
GRIN mows the grass & pulverizes it
The mowed grass remains suspended for a few fractions of a second inside the patented Grin mowing deck. It is centrifuged and pulverized, thanks to the vortex created by the patented Grin blade combined with the effect of a Grin helix disc
Pulverize and fertilise!
In this way the grass loses most of its volume and is pulverized into tiny little and virtually invisible particles. These particles fall directly onto the soil (they do not remain on the surface of the lawn!) and are absorbed in a very short time.
Create a perfect, healthy lawn
GRIN optimally processes the grass inside the mowing deck, pulverizing everything into extremely fine particles, which become an excellent fertilizer for your lawn!
Leaves are transformed into fertilizer
The patented mowing system – MOWING, NO GRASS BAG, NO WASTE – developed by Grin is also effective with leaves. The leaves are ground inside the mowing deck and transformed into fertilizer for your lawn.
If the leaves are fine ground by the GRIN system, they become an excellent nourishment for the lawn because they are rich of carbon. The night humidity and the microorganisms of the terrain help the absorption, so that the soil becomes more fertile and consequently more beautiful.
In this way, there is no need to waste time and effort in collecting the leaves and disposing of them.
GRIN vs Mulching
The patented Grin system - MOWING, NO GRASS BAG, NO WASTE - must not be mistaken for the CONVENTIONAL MULCHING mowing system. Both systems are based on bag-less mowing, but were developed to meet different needs.
The main differences between the two systems are:
- MOWING HEIGHT AND FREQUENCY: With Grin it is possible to maintain the same mowing height and mowing frequency as with a grass bag type mower.
- GRASS PULVERISATION: In standard mowing conditions, Grin pulverises grass into very fine fragments, which are deposited on the soil and absorbed as fertiliser.
- MOWING WET GRASS: With Grin it is possible to mow wet grass much better than with a grass bag type mower.
