The Ryobi 18V ONE+ Lawnmower RB18L50 delivers cordless cutting freedom with a complete lawn care solution. This kit combines a 33cm cutting width mower with a 25cm path grass trimmer.
The mower features 5-position height adjustment from 25-65mm and an EasyEdge grass comb for cutting right to garden edges. The ergonomic handle adjusts to three heights whilst the 35L collapsible grass catcher includes a mulching plug.
Both tools share the included 5.0Ah ONE+ Lithium+ battery with four-stage fuel gauge and IntelliCell monitoring. The grass trimmer features auto-feed spool technology and EasyEdge mode switching for precise edging work.
Runtime depends on grass conditions and cutting height. The 5.0Ah battery typically provides 30-45 minutes of continuous mowing on average lawns. Longer or thicker grass reduces runtime as the motor works harder. The four-stage fuel gauge helps you monitor remaining charge during use.
Yes, all Ryobi ONE+ batteries are compatible including 1.5Ah, 2.5Ah, 4.0Ah and 6.0Ah versions. Higher capacity batteries provide longer runtime whilst smaller batteries reduce weight. The mower works with both older and newer ONE+ battery generations.
With the 5.0Ah battery, this mower suits lawns up to 300-400 square metres depending on grass conditions. The 33cm cutting width covers ground efficiently whilst the battery capacity supports extended cutting sessions. Multiple batteries allow coverage of larger areas.
The grass comb extends beyond the cutting deck to guide grass stems into the blade path. This allows cutting right up to walls, fences and flower beds without leaving uncut strips. The comb prevents the mower deck from hitting obstacles whilst maintaining cutting performance at edges.
The trimmer handles light to medium weeds effectively with its 25cm cutting path. Very thick or woody stems may require multiple passes or pre-cutting with secateurs. The auto-feed spool maintains cutting line length automatically as you work through different vegetation types.
The EasyEdge feature allows quick rotation of the trimmer head from horizontal trimming to vertical edging position. Simply rotate the cutting head 90 degrees to edge along paths and borders. No tools are required for this adjustment during operation.
Regular maintenance includes cleaning the cutting deck after use and checking the blade for damage. The grass catcher should be emptied and cleaned regularly. Battery terminals need occasional cleaning whilst the blade may require sharpening or replacement after extended use depending on cutting conditions.
Yes, the included mulching plug blocks the grass catcher opening and redirects clippings back onto the lawn. The blade cuts clippings into small pieces that decompose quickly and feed the grass. Remove the grass catcher and insert the mulching plug to activate this mode.
