The Izy is one of Honda’s distinct line of four-wheeled rotary mowers. The HRG 466 offers the same exceptionally high levels of performance as the other mowers in the series, but the main advantage comes in the form of versatility, i.e., the mulching kit.
The HRG 466 comes with two cutting modes, the traditional cut and collection and the mulching feature. Its mulching function cuts and re-cuts grass grass to an extremely fine extent, allowing accurate redistribution. The grass is then embedded deep within the soil, acting as a natural fertiliser.
The mulching kit comes as a fitted standard and also allows you flexibility with regards to the height of cut. The setting allows you to choose between six different height settings, ranging from 20mm to 74mm, ensuring fine finishing for all grass types.

Main Benefits:

  • The 46cm steel cutting deck, primed to resist rust, UV abrasion and general wear and tear
  • A 55 litre grass bag designed with high airflow ventilation allows for large cut storage and performance
  • Mulching kit allows for grass redistribution and natural fertiliser
  • Easy starter thanks to the auto-choke system
  • Cut adjustment height allows for precision cutting
