Makes you wonder what impeller/blade configurations they tried, i.e., how many failures preceded the current design. Did they try a lift-blade?

Mower Trimmer Mash-up

Ya know, I assumed (and ya know what happens when ya do that) the Flymo blades both cut the grass and provided lift. Then I turned the mower over.

Flymo Hovering Mowers

Came home Saturday evening to find a strange lawnmower on the lawn next to my driveway. This is not a normal occurrence in my world. It was a walk-behind with a bright orange deck, had no wheels and...

Lawn Theory

Perhaps your landlord could be persuaded that a “test bed” of native grasses in one corner of the back yard is reasonable. You might even segregate the test bed from the lawn with some type of border...

The AC Mower Essay

I replaced the cranky, leaky, noisy ICE on this walk-behind mower with a motor from a washing machine. Now I can mow without earplugs, hear the birds chirping and the cicadas droning, and even listen...
