The STIHL RMA 453 PV Cordless Lawn Mower is a powerful and versatile battery-powered mower designed for large domestic lawns. Part of the STIHL ALLPRO/AP System, it combines a 51cm cutting width, Vario self-propelled drive, sequential dual-battery operation and a flexible 4-in-1 mowing system for outstanding performance and convenience.

The STIHL RMA 453 PV Cordless Lawn Mower is a premium battery-powered mower designed for homeowners who want professional-inspired features combined with the convenience of cordless mowing. Part of the STIHL ALLPRO/AP System, this feature-packed mower offers impressive power, quiet operation and excellent versatility, making it ideal for maintaining large domestic lawns.

Built around a robust polymer deck, the RMA 453 PV is both lightweight and highly durable. The housing is rust-proof, UV-resistant and double-layered for increased strength and longevity, making it well suited to regular use throughout the mowing season.

With a generous 51cm (20″) cutting width and centrally controlled cutting height adjustment ranging from 20mm to 100mm, the RMA 453 PV can tackle larger lawns quickly while still delivering a high-quality finish. Powered by the STIHL ALLPRO/AP System, the mower is recommended for use with the AP 300 P battery, delivering mowing coverage of up to 540m² on a single battery and up to 1080m² when operating with two AP 300 P batteries.

A key feature of the RMA 453 PV is its intelligent sequential battery discharge system. When two batteries are fitted, the mower automatically switches from the first battery to the second when required, eliminating interruptions and allowing you to continue mowing without stopping.

The versatile 4-in-1 mowing system allows you to choose the most suitable mowing method for your lawn. Grass can be collected in the catcher box, discharged from the rear, discharged from the side or mulched back into the lawn using the supplied mulching attachment.

The integrated Digital HMI display provides easy access to battery charge information, drive settings and mowing modes, while the Vario self-propelled drive allows you to adjust the mowing speed to suit your pace and lawn conditions.

A 55-litre grass collection box with fill-level indicator, comfortable mono-handlebar design and foldable construction make the RMA 453 PV practical, comfortable and easy to store when not in use.

Please note that the RMA 453 PV is only available as a tool only, the battery and charger are sold separately.

Domestic Warranty: 2 Years Standard / 5 Years Extended* (subject to registration and servicing requirements)

The mono-comfort handlebar also benefits from: 10-Year Domestic Use Warranty
