Description
Patented Grin Mowing System – No Grass Bag, Zero Waste
The GRIN HM46 mulching lawn mower is one of the most popular petrol-powered machines in the GRIN range. Built on the proven GRIN chassis, it features the powerful and reliable Briggs & Stratton 675 Series, 163 cc engine with READY START, ensuring effortless start-up every time.
Compact and Manoeuvrable Mulching Mowers for Any Lawn Size
This mulching mower excels in tight spaces thanks to its compact chassis, double ball bearing wheels, and lightweight 27 kg frame. It easily navigates around trees, flowerbeds, garden lanes, and other obstacles.
For lawns with rocky or uneven terrain, an optional engine protection cone ensures consistent performance while keeping your mower safe.
46 cm Cutting Width – Quick Lawn Maintenance
With a 46 cm cutting width, this mower allows fast and efficient maintenance for lawns up to 800 m². Because it is a mulching lawn mower with no grass bag, the weight remains low, ensuring smooth operation on flat surfaces without added effort from collected clippings
Effortless Handling – Lightweight and Comfortable
Pushing the GRIN HM46 is easy and comfortable for users of all abilities. The absence of traction systems prevents any resistance during operation, and the solid, durable chassis provides long-term reliability.
Mow N’ Stow – Space Saving Storage for Mulching Mowers
The GRIN HM46 supports the Mow N’ Stow feature, allowing vertical storage to save space and protect your mower when not in use.
