Why Choose the RMA 448 V?
This model combines the power and convenience of cordless technology with STIHL’s build quality. Its variable-speed self-propel system makes mowing less physically demanding.

Suitable For
- ✔ Medium to large domestic lawns
- ✔ Gardeners who value quiet, eco-friendly performance
- ✔ Users needing flexible mulching, collection, or discharge options
- ✔ Anyone seeking easy handling, compact storage, and low maintenance
What’s in the Box?

Please note: Battery and charger are sold separately.

FAQs

A: ECO mode optimises blade speed depending on grass resistance, saving battery energy for longer mowing sessions.
