The Ryobi RLM18X33B40 lawn mower delivers cordless freedom for small to medium gardens up to 100 square metres. This lightweight 11.09kg mower features a 33cm cutting path that makes manoeuvring around obstacles simple.
The EasyEdge grass comb draws grass from the side into the blade path. This lets you cut right up to fences and walls without needing a separate trimmer. Single-point height adjustment offers five cutting positions from 25mm to 65mm.
The ergonomic handle adjusts to five different heights for user comfort. Folding handles and a collapsible grass catcher make storage compact. The 4.0Ah battery provides sufficient power for typical small garden cuts in one charge.
Battery runtime depends on grass conditions and cutting height settings. For typical small gardens up to 100 square metres, the 4.0Ah battery provides sufficient power for a complete cut. In longer or thicker grass, you may need 10-15 minutes of cutting time. Using higher cutting positions extends battery life significantly. Many users report completing their entire lawn on one charge, though having a spare battery ensures uninterrupted mowing for larger areas.
This mower works best for small to medium gardens up to 100 square metres. The 33cm cutting width makes it ideal for gardens with flower beds, trees, or other obstacles requiring careful navigation. For larger open lawns, you might prefer a wider cutting deck model. The lightweight design and compact size make it perfect for terraced houses, small suburban gardens, or courtyard spaces.
Yes, all Ryobi ONE+ 18V batteries work with this mower. Higher capacity batteries like 5.0Ah or 6.0Ah provide longer runtime for larger gardens. The intelligent battery management system protects against overheating and extends battery life. You can interchange batteries between all Ryobi ONE+ tools, making it cost-effective if you already own other tools in the range.
The EasyEdge grass comb extends from the mower's side to guide grass toward the cutting blade. This eliminates the typical 2-3cm gap between the blade and mower edge. You can cut flush against walls, fences and borders without needing separate trimming. The comb is particularly effective on longer grass that would normally bend away from the blade.
Assembly takes approximately 5-10 minutes and requires only basic tools. You need to attach the handle using four bolts, which are included. The grass catcher clips on without tools. The battery comes pre-charged in most cases, so you can start mowing immediately after assembly. The instruction manual uses clear pictorial guides for each step.
Insert the battery and ensure it clicks securely into place. Hold down the safety release button while squeezing both handle levers simultaneously. The dual-safety system prevents accidental starting. Release either lever to stop the mower immediately. The safety key system means the mower cannot operate without a properly inserted battery.
Maintenance is minimal compared to petrol mowers. Clean the deck after each use to prevent grass buildup. Check the blade periodically for sharpness and damage. The blade can be removed and sharpened or replaced when necessary. Keep the battery contacts clean and store batteries in a dry location. No oil changes, spark plugs, or air filters to maintain.
The grass catcher holds a substantial amount of clippings and has good airflow for efficient collection. The collection rate depends on grass conditions - dry grass collects better than wet grass. The catcher has clear sides so you can see when it needs emptying. It detaches easily for disposal and cleaning. Some users prefer to mulch by removing the catcher for natural lawn fertilisation.
