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.
In order to achieve the same result with conventional mulching, the lawn must be mowed more than once a week, in the periods when grass grows fast, and moreover only when it’s very short.
In standard mowing conditions, Grin pulverises grass into very fine fragments, which are deposited on the soil and absorbed as fertiliser.
On the other hand, in standard mowing conditions, conventional mulching leaves patches of grass on the surface of the lawn, difficult to be absorbed by the soil and running the risk of suffocating the lawn
With Grin it is possible to mow wet grass much better than with a grass bag type mower.
With conventional mulching, the limited size of the mowing deck makes mowing wet grass difficult.
You can’t see the pulverized grass on top of the lawn
Under normal mowing conditions, GRIN pulverizes grass so fine that it falls through the grass directly onto the soil, to be absorbed as natural fertilizer. In this way, the aesthetic result of mowing with Grin is similar to the one obtained with a mower with grass-bag. Under similar mowing conditions, conventional mulching merely cuts grass, which remains on the surface of the lawn, making absorption by the soil difficult. The risk of grass accumulation and lawn suffocation is therefore very high. Moreover, when it dries up, it remains visible on top of the lawn, looking unaesthetic.
The Grin mowing deck mows also tall grass
The Grin mowing deck is about 30% higher than conventional mulching machines. The shape and the position of the blade make the volume of a Grin mowing deck about 50% larger than conventional mulching machines. 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 blade centrifuges the mowed grass
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.
The mowing system of a mulching machine normally consists of a curved blade that cuts the grass into several segments, the first time during mowing and then when the cut segment falls down. When the length of the grass to mow exceeds 8-10 cm, the cut segments remain long and visible.
