The 40V 40cm cordless lawn mower from Yard Force suits medium to large gardens. It runs on two 20V lithium-ion batteries giving 40V combined power and both battery and charger are included. The brushless motor runs quieter than standard brushed motors, uses less energy and lasts longer under regular use.
A 40cm steel deck covers more ground per pass. Seven cutting heights run from 25mm to 75mm, changed through a Push & Adjust system. Torque Sensing Boost technology raises power automatically when grass thickens, keeping the cut even across the lawn.
A rear roller presses grass down as you mow, creating striped lines and adding stability near edges. The 45-litre grass bag means fewer stops to empty. Cut-to-edge blade design lets you mow right up to borders, walls and flower beds.
This mower works best on medium to large gardens. The 40cm cutting width covers more ground per pass than smaller mowers, so you spend less time going back and forth. If your lawn is small with lots of tight corners, a narrower mower might suit better. But for an average-sized or larger lawn, the wider deck cuts mowing time down noticeably.
The mower runs on 40V power drawn from two 20V lithium-ion batteries working together. Battery and charger come included in the box. Yard Force offers a few configurations depending on which model pack you buy - including 2 x 20V/4.0Ah 1 x 20V/4.0Ah 1 x 20V/5.0Ah and 2 x 20V/2.5Ah. Higher Ah ratings mean longer runtime per charge. Since both batteries are part of the CR20 range they can also power other compatible Yard Force 20V tools.
There are 7 cutting height positions ranging from 25mm up to 75mm. Height is changed using Yard Force's Push & Adjust system which is a single lever mechanism rather than fiddling with separate wheel adjusters. Want a close summer cut or a longer shaded lawn look? Both are easy to dial in without tools.
Yes. It has a rear roller built in which presses grass down as you mow to create the classic striped lawn effect seen on cricket pitches and formal gardens. The roller also adds stability when mowing along edges so the mower tracks straighter near borders and walls.
The brushless motor runs quieter than typical brushed motors found on budget mowers. It's also more energy efficient which means better use of your battery charge per session. Yard Force says motor life is longer too since there's no brush friction wearing parts down over time. On top of that, Torque Sensing Boost technology automatically increases power when it senses thicker or longer grass, so the cut stays consistent instead of bogging down.
The grass bag holds 45 litres, which is on the larger side for a cordless mower in this class. A bigger box means fewer stops to empty it during a mowing session, particularly useful on bigger lawns where constant stopping slows you down. If you'd rather not collect clippings at all, a mulching plug is also available so clippings get broken down and returned to the lawn as a natural feed.
Yes. It has a cut-to-edge design with front and side combs that guide grass toward the blade right at the mower's edge. This means less need for separate edge trimming after mowing near flower beds, walls or fence lines. The blade itself is steel built for durability under regular use.
The box includes the mower body battery charger and grass collection bag. It weighs 14.1kg and measures 102cm deep 46cm wide and 131cm high in its assembled state. Yard Force supports this 40V 40cm cordless lawn mower with 5 years of EU spare part availability so parts shouldn't be hard to find down the line. Amazon's standard 30-day return policy also applies if the mower doesn't suit your needs once it arrives.
