How about a no-noise, no-smoke, no crude oil, healthy way to cut grass and harvest grain crops ? Imagine being able to mow & edge grasses without goggles and earmuffs, and being able to hear the birds twitter ?
Pick up a Scythe and swing it around - a simple replacement for the mower and the whipper-snipper, and you can use it to harvest grains & control weeds. Indeed, in the mid 19th century there were over a million scythes in the USA, used to gather the harvest (no combine tractors then !).
Join the Bega Scythe users group, arrange a scythe demonstration in your area, buy a scythe, or even make one.
