The Ryobi OLM1833B lawnmower delivers cordless convenience for gardens up to 250m². This 18V ONE+ system mower eliminates dangerous mains cables and messy petrol engines.
Features a 33cm cutting path with five adjustable height settings from 25-65mm. The innovative edge grass comb lets you mow right to lawn perimeters without additional trimming tools.
Includes the RC18150 5.0A battery charger which powers 5.0Ah batteries in just one hour. The 3-position telescopic handle adjusts for comfortable operation while the lightweight design reduces fatigue during extended use.
The Ryobi OLM1833B handles gardens up to 250m² when paired with a 5.0Ah ONE+ battery. The 33cm cutting width makes it ideal for small to medium-sized lawns. For larger areas, you may need additional batteries or consider a wider cutting deck model.
Battery runtime depends on grass conditions and cutting height settings. A 5.0Ah battery typically provides 30-45 minutes of continuous mowing. Dense or wet grass reduces runtime whilst lighter conditions extend operating time. The included charger restores full power in 60 minutes.
Yes, all Ryobi ONE+ 18V batteries work with this lawnmower. The system supports battery capacities from 1.5Ah to 9.0Ah. Higher capacity batteries provide longer runtime whilst smaller batteries reduce overall weight. This compatibility maximises your existing battery investment.
The edge grass comb guides grass into the cutting blades right to lawn perimeters. This feature works effectively along straight edges like pathways and borders. However, complex shapes around curved flower beds or intricate landscaping may still require some manual trimming for perfect results.
Regular blade cleaning after each use prevents grass buildup and maintains cutting performance. Check blade sharpness monthly and replace when worn. The battery requires no maintenance beyond proper charging cycles. Store the mower in dry conditions and clean the deck periodically to prevent corrosion.
The five cutting height positions adjust from 25mm to 65mm using a single lever mechanism. Each position clicks securely into place for consistent cutting depth. The adjustment works quickly without tools, allowing height changes between different lawn areas during the same mowing session.
Like most electric mowers, performance decreases in wet conditions. Wet grass clogs the deck more easily and requires more battery power. For best results, mow when grass is dry. If you must cut damp grass, use higher cutting settings and clean the deck frequently during operation.
The bundle includes the OLM1833B lawnmower body and the RC18150 5.0A battery charger. You'll need to purchase an 18V ONE+ battery separately to operate the mower. The charger features LED indicators and maintenance functions to optimise battery performance and lifespan.
