I spotted the Greenworks G-MAX 50Li-40V Lithium-Ion 3-in-1 Twin-Force Cordless Lawnmower for sale on the MowDirect web site.
This Greenworks lawnmower is a high end rechargeable machine designed to be a viable alternative to petrol lawnmowers.
- 49cm cutting width
- Twin blade cutting system
- Cutting height 35-85mm (5 positions)
- Supplied with two 40V Li-ion batteries
- 60 litre grass collector
I found a couple of video reviews of what seems to be a slightly different version of the Greenworks Twin-Force cordless lawnmower, the second from the same person as the first is a quick update after having the mower for a year.
