Mow more lawn with less effort using the RYOBI 2x18V ONE+ Brushless 51cm (20”) Self-Propelled Lawn Mower. Its HP brushless motor produces more power for cutting thick lawns with broad-leaf grass types. WHISPER series Cross Cut blades leave a crisp finish on lawns while emitting less noise than standard blades. Self-propelled speed drive takes the hard work out of mowing up slopes or for extended periods. Mow at your own pace by using the variable speed slider on the handle to adjust driving speed. The 51cm-wide deck reduces the number of passes required for mowing lawns. The 3-in-1 discharge system gives you the option to catch, mulch or side-discharge. Choose your preferred cutting height (25-90mm) using the 7-step height adjustment. Quick-release handles make it easy to store the mower vertically. The mower has 4 battery ports – two active 18V battery ports are used to power the mower and two for on-board storage, making it easy to swap over batteries on the go and extend runtimes. Get up to 40 minutes of runtime with two 18V ONE+ 4.0Ah batteries* connected. This Mower runs on the same 18V ONE+ batteries that power more than 120 tools from RYOBI’s ONE+ range. So, there are no pull cords, petrol top-ups or nasty exhaust fumes to deal with. It’s part of RYOBI’s ONE+ HP series of tools that utilise advanced technologies, like brushless motors that deliver higher performance, extended battery runtimes and longer motor life. These tools are ideal for tough conditions and larger gardens with mature plants. They also have superior ergonomics for a premium user experience. *18V ONE+ 4.0Ah batteries not included.
