COBRA MX51S40VX Cordless Lawnmower Review
I test mowers to find practical, real-world answers for homeowners deciding whether to switch to battery power. The Cobra MX51S40VX caught my eye because it’s a 51 cm (20″) mower with a steel deck, self-propelled drive, and a twin 40V Max+ battery system. On paper it looks like a genuine petrol alternative, so I wanted to know how it performs when the conditions are far from perfect—wet grass, long growth and leaf-strewn lawns.
