Power, Precision, and Perfect Stripes

Turn your lawn into a masterpiece with the Mountfield Empress 46 Roller Li lawnmower. Designed for gardeners who demand the best, this cordless roller mower combines cutting-edge battery technology with robust features to deliver a stunning, professional-looking striped finish on lawns up to 550m².

Cleaner, Quieter, and Packed with Power

The Empress 46 Roller Li is powered by two 48V STIGA ePower Lithium-Ion batteries working in unison to drive a powerful 1500W brushless motor. This advanced system delivers performance comparable to a petrol engine but without the noise, emissions, or hassle of fuel and oil. Enjoy a quieter, more pleasant mowing experience that’s better for you and your neighbours. With no spark plugs or filters to worry about, maintenance is virtually zero.

Effortless Mowing and a Flawless Finish

The self-propelled rear-roller drive makes mowing larger areas a breeze, moving at a comfortable fixed speed of 4.1 Km/h. The 46cm cutting width covers ground efficiently, while the robust steel deck ensures durability. The full-width rear roller is the key to achieving that quintessential striped effect, pressing the turf after cutting for a crisp, defined look. Adjusting the cutting height is simple, with a single central lever offering five positions from 20mm to 70mm, allowing you to handle everything from a light trim to longer grass.

Designed for Convenience

This mower is packed with user-friendly features. The generous 55-litre hybrid grass collector includes a handy ‘bag full’ indicator, letting you know exactly when it’s time to empty, reducing guesswork and unnecessary stops. The ergonomic handlebar features a double hand switch for comfortable operation and can be adjusted and folded down for compact storage. A front bumper handle provides protection and makes the mower easier to lift and move.

Frequently Asked Questions

What size lawn is the Mountfield EMPRESS 46 Roller Li suitable for?

This model is ideally suited for lawns up to 550 square metres, which is typical for many medium-sized British gardens. Its 46cm (18″) cutting width provides a good balance between coverage and manoeuvrability.

Does this mower come with everything I need to get started?

Yes. This is the ‘Kit’ version, which means it comes complete with two 48V 4Ah STIGA ePower batteries and a dual battery charger. Everything you need to charge up and start mowing is included in the box.

How do I get the best striped finish with this mower?

The full-width rear roller is the key component for creating stripes. For the best effect, mow in straight, parallel lines, slightly overlapping each pass. At the end of each line, lift the mower and turn before starting the next line in the opposite direction.

What maintenance does this cordless lawnmower require?

Compared to a petrol mower, maintenance is minimal. The main tasks are to keep the underside of the deck clean and free of grass clippings, ensure the blade remains sharp, and keep the batteries charged. For annual check-ups and blade sharpening, you can book a service with our trained technicians through our servicing page.
