Grin HM46 is one of the most popular machines in the Grin range with combustion engine.

Built on the proven Grin chassis, it is mounted with the powerful and reliable 5.5 HP Briggs & Stratton 675 series engine with READY START for an easy start up.

The most impressive feature of this lawnmower is its manoeuvrability: Its compact chassis, the wheels on double ball bearings, the low weight of 28 kg and the streamlined mowing deck make it the ideal machine to manoeuvre in between trees, flower beds, lanes and all the other obstacles in the garden. In spite of that, its 46 cm mowing deck makes easy and quick work up to 800 mq2.

The fact it has no traction goes unnoticed on level lawns: Grin lawn mowers have no grass bag, hence the machine stays light; there is no grass bag that fills up. Pushing the Grin HM46 is easy and comfortable for everyone and there is no traction which counteracts manoeuvring.

The chassis of this machine is very solid and durable. In case of particularly rocky or rough terrain it is possible to retrofit the ENGINE PROTECTION CONE as an option.

V.I.P. very important part
Optional and accessories

Have you ever accidentally hit a stone with your lawn mower and damaged the crankshaft?

Being distraction or due to just bad luck, small “accidents” may happen, which may lead to damaging the lawnmower’s mechanics.

Grin has introduced a device called ENGINE PROTECTION CONE to minimise these risks.
