Product information & specifications
Effortlessly maintain your lawn with the STIHL RM443.3T, a powerful and versatile self-propelled lawn mower. This petrol-powered mower boasts a 16-inch cutting width, ideal for medium-sized gardens up to 1200 square meters.
Navigate slopes and uneven terrain with ease thanks to the self-propelled drive system, while the lightweight, rust-proof polymer deck ensures durability and manoeuvrability.
Choose from four mowing options:
- Collect grass clippings in the large 52-litre grass catcher for a clean finish.
- Mulch clippings back into the lawn for a natural fertilizer boost.
- Side discharge clippings for taller grass or areas you plan to compost later.
- Cut & drop clippings for quick mowing without collection.
Enjoy additional features like a single-point height adjustment, comfortable mono-handlebar, and easy-to-empty grass catcher with a fill level indicator.
The STIHL RM443.3T is a reliable and efficient choice for homeowners seeking a powerful and feature-rich lawn mower experience.
