The Kärcher LMO 18-36 is a lightweight cordless lawn mower designed for gardens up to 350m². This battery-powered machine weighs just 13.27kg making it easy to manoeuvre across uneven terrain.
What makes this mower special? The 2-in-1 cutting system lets you collect grass in the 45-litre box or mulch directly onto your lawn as natural fertiliser. The 36cm cutting width handles most domestic lawns efficiently.
Key features include four adjustable cutting heights from 30-70mm, foldable handles for compact storage and lawn combs for precise edge cutting. The included 18V 5.0Ah battery provides up to 24 minutes runtime with the fast charger ensuring minimal downtime between cuts.
The included 18V 5.0Ah battery provides up to 24 minutes continuous runtime, covering approximately 350m² on a single charge. Battery life depends on grass conditions, cutting height and terrain. Longer grass or wet conditions will reduce runtime, whilst regular cutting on dry lawns maximises coverage. The fast charger restores full power in under 90 minutes.
Yes, the 2-in-1 system includes a mulching plug that blocks the chute to the grass box. When fitted, the mower finely chops clippings and distributes them back onto the lawn as natural fertiliser. This eliminates emptying the grass box and provides nutrients to your lawn. Simply remove the plug when you want to collect clippings instead.
The 36cm model (LMO 18-36) has a wider cutting deck than the 33cm version, reducing mowing time on larger lawns. Both use the same 18V battery system and offer identical cutting height ranges. The 36cm version is slightly heavier but covers more ground per pass, making it more efficient for gardens over 200m².
The lightweight 13.27kg design and low centre of gravity make this mower stable on gentle slopes and uneven terrain. The compact wheelbase helps navigate bumps and dips. However, avoid using on steep inclines over 15 degrees for safety. The mower performs best on relatively level ground with occasional undulations.
A single lever beside the rear wheels adjusts cutting height across four positions: 30mm, 45mm, 60mm and 70mm. Simply lift the lever, slide to your preferred position and release. Lower settings suit fine grasses and formal lawns, whilst higher cuts help during dry periods or for meadow-style gardens.
Clean the cutting deck after each use to prevent grass buildup. Check the blade sharpness monthly - replace when cutting becomes ragged. Keep air vents clear of debris for proper motor cooling. Store the battery indoors during winter and charge every 3 months when not in use. The plastic deck won't rust but inspect for cracks or damage regularly.
Yes, additional 18V batteries are available separately and compatible with the entire Kärcher Battery Power platform. A second 5.0Ah battery effectively doubles your mowing capacity to 700m² without waiting for charging. Smaller 2.5Ah batteries are cheaper but provide roughly half the runtime and coverage area.
With handles folded, the mower measures approximately 51.5cm deep, 41cm high and 15.7cm wide. This compact footprint fits in most garden sheds, garages, or even large cupboards. The foldable handle design reduces storage space by over 50% compared to fixed-handle mowers, making it ideal for homes with limited storage space.
