The 40V 37cm Cordless Lawnmower LM G37A from Yard Force is built for lawns up to 400m². It runs on a 40V 2.5Ah lithium-ion battery with a quick charger included. The brushless motor uses Torque Sense Boost Technology to adjust power output as grass thickness changes. No petrol and no cables to trip over.
Cutting height adjusts from 25mm to 75mm across 7 positions using a single central lever. The 37cm cutting width suits small to medium gardens. A rear roller presses the lawn as you mow, leaving classic stripes behind.
Grass goes into a 40 litre hybrid collection bag with a full level indicator. The bag design compresses clippings so you empty it less often. At 16kg the mower is light enough to lift and store. It comes with a 2 year warranty, extendable to 3 years on registration.
Battery life depends on grass length and lawn size. Customer reports vary widely. One reviewer with a 295m² lawn got 39 minutes of cutting time before needing a recharge. Another with an 85m² lawn managed the full area with charge to spare in around 30 minutes. The 2.5Ah lithium-ion battery takes roughly 40-60 minutes to fully recharge using the included quick charger. Keep in mind that battery performance can decline over time. Some long-term owners reported reduced capacity after 18 months to 2 years of regular use, so factor this into your buying decision if you have a larger lawn.
Yard Force states this mower suits lawns up to 400m². However real-world reviews suggest this figure may be optimistic for a single charge, especially with longer grass. Several users with lawns under 300m² needed to recharge mid-mow. If your lawn is on the larger end of this range, consider buying a second battery so you're not stuck halfway through mowing. The battery and charger are interchangeable with other products in the Yard Force GR40 range.
Assembly experiences differ quite a bit among buyers. Some found it straightforward, taking under 5 minutes once the handle was attached. Others found the process more fiddly, particularly when fitting the grass collection bag and handle bars. One common complaint was that the included instructions don't always match the actual cabling and parts in the box. Budget around 20-25 minutes for assembly to be safe. The basic steps involve attaching the handle, connecting the cables and fitting the grass bag.
The mower has 7 cutting height positions ranging from 25mm to 75mm. Adjustment is done using a single central lever, which most reviewers found quick and easy to use. This range suits most lawn types, from a close cut for a tidy finish to a longer cut during dry summer months when grass needs more length to stay healthy.
Yes. The mower has a rear roller specifically designed to create a striped finish on your lawn. Multiple reviewers confirmed this feature works well, with one describing the results as giving "better looking lawns." The front and side combs also help achieve a cleaner edge cut around borders and obstacles.
The mower weighs 16kg and measures 140cm deep, 106cm wide and 41cm high. Most reviewers describe it as lightweight and easy to push, even for people with health issues or back problems. One reviewer specifically noted it allowed single-handed use in awkward spots thanks to the handle design. It folds down for storage, with several owners mentioning it fits into small storage spaces like under a work bench.
The mower comes with a 40 litre hybrid grass collection bag designed for optimal airflow. This compresses clippings, meaning fewer trips to empty it compared to standard bags. A grass full level indicator shows when the bag needs emptying. That said, some reviews mention the indicator doesn't always work accurately, staying down even when the bag is full. A mulching plug is also included if you'd rather leave clippings on the lawn instead of collecting them, though this isn't always mentioned clearly in the instructions.
Yard Force offers a standard 2 year manufacturer warranty. If you register your purchase within 28 days, you get an additional year, bringing total coverage to 3 years. Yard Force also provides after-sales support 7 days a week. Given that some reviewers reported battery and build quality issues after 1-2 years, registering promptly for the extended warranty is worth doing as soon as you unbox the mower.
