Ryobi 18V ONE+ Cordless Lawnmower And Grass Trimmer Twin Kit (RLM1833BLT1825M)

How long does the 4.0Ah battery last during mowing?

Battery runtime varies significantly based on grass conditions and cutting height settings. For typical small gardens up to 100 square metres, the 4.0Ah battery provides 15-20 minutes of continuous mowing. Longer grass or lower cutting heights reduce runtime to 10-15 minutes. The battery performs best on dry grass at higher cutting positions. Many users find one battery sufficient for gardens up to 25-30 metres in length, though having a spare battery ensures uninterrupted cutting for larger areas.

What cutting width does the lawnmower have and is it suitable for narrow spaces?

The lawnmower features a 33cm cutting width, making it ideal for small to medium gardens with narrow pathways or tight spaces. This width allows easy manoeuvrability around garden furniture, flower beds and between closely planted areas. The compact design means you can navigate gates as narrow as 40cm whilst still maintaining efficient cutting coverage. For very large open lawns, the 33cm width may require more passes compared to wider mowers.

Can I use other Ryobi 18V batteries with this mower?

Yes, the mower accepts all Ryobi 18V ONE+ batteries including 2.0Ah, 3.0Ah, 4.0Ah, 5.0Ah and 6.0Ah capacities. Higher capacity batteries like the 5.0Ah or 6.0Ah provide longer runtime and maintain power better under load. The mower automatically adjusts to different battery capacities. Third-party compatible batteries also work, though performance may vary. The battery slides in securely and includes charge level indicators to monitor remaining power during use.

How do I adjust the cutting height and what heights are available?

The single-point height adjustment lever is located centrally and operates all four wheels simultaneously. Five positions range from 25mm (position 1) through to 65mm (position 5). Position 1 creates a close, formal lawn finish whilst position 5 handles longer grass and reduces battery drain. The adjustment requires no tools and can be changed between cutting sessions. Most users find positions 2-3 ideal for regular weekly cutting of established lawns.

Does the grass trimmer work effectively for edging along pathways?

The 25cm grass trimmer includes EasyEdge functionality that rotates the cutting head 90 degrees for precise edging work. The auto-feed spool releases cutting line automatically as it wears down, maintaining consistent cutting performance. The lightweight design reduces fatigue during extended edging sessions. The trimmer handles grass edges, light weeds and overgrown areas around paths, driveways and fence lines effectively. Battery life typically provides 20-30 minutes of trimming depending on vegetation thickness.

How much storage space does the mower require when folded?

With handles folded and grass catcher collapsed, the mower measures approximately 72cm deep, 51cm wide and 40.8cm high. The compact folded size fits in most garden sheds, garages or storage cupboards. The grass catcher folds completely flat, reducing storage volume significantly. Handle removal is possible for even more compact storage if required. The lightweight construction makes lifting onto shelves or storage hooks manageable for most users.

What maintenance does the mower require and how often?

Regular maintenance includes cleaning grass debris from the cutting deck after each use and checking blade sharpness monthly. The metal blade may require sharpening or replacement annually depending on usage frequency and ground conditions. Battery terminals should be kept clean and dry. The grass catcher requires occasional washing to maintain airflow. No oil changes, spark plug replacements or fuel system maintenance are required unlike petrol mowers, significantly reducing ongoing maintenance requirements.

Is the mower suitable for wet grass cutting?

The mower can handle slightly damp grass better than corded electric mowers due to the cordless design eliminating electrical safety concerns. However, very wet grass clogs the cutting deck and reduces battery life significantly. The plastic construction resists moisture damage but wet grass clippings stick to surfaces requiring more frequent cleaning. For best results, wait until grass is dry or only slightly damp. The mower's performance and battery runtime improve dramatically on dry grass compared to wet conditions.
