Grass Cutting with Scythe & Moisture

For some reason mowing your lawn with a scythe is spectacularly efficient only when the grass is wet (talking about cutting the grass down to essentially ground level, a regular short mowing). The cutting is done with a razor-sharp edge that advances mostly along its length but somewhat across the grass as well, so it's a slicing like slicing bread. Two things make it not work very well. 1, the grass simply bends out of the way and so is not cut. 2, the grass cuts partly but sticks on the edge, forming a clump of grass, which stops the slicing action and the blade goes unstable (if it's a long one), generally burying its point very quickly. When the grass is wet, what happens instead? One possibility is that wet grass has more momentum and so doesn't bend out of the way when it encounters the blade. Another is that wet grass is softer or somehow more sliceable. A third, which I suspect is true, is that the grass is slippery when wet, and doesn't clump on the edge, so the whole length of the edge works on all the blades without their being torn out by the root first. Various blade styles work differently but all seem to work best when it's wet. http://www.scythesupply.com I'm using the 36" grass blade, mostly. It's unuseable when the grass is dry owing to going unstable, but it turns you into a regular John Henry cutting out 7' swaths of lawn in the wet, shovelling huge heaps of grass clippings into a pile at one side with each stroke. Shorter grass blades don't go unstable in the dry, so are useable, but don't cut very quickly. This is all talking about regular lawn grass, not standing wheat or anything. Tall grass is another hobby. -- Ron Hardin On the internet, nobody knows you're a jerk. Wet grass is more rigid. Rigid things slice easier.

For some reason mowing your lawn with a scythe [snip] Socks lives in a condo. The building staff look after that. Odd thing. I've lived in the same building for ten years and can't say I've ever seen them cut the lawn. I've seen them shovel snow, trim the hedges, wash the windows, etc. etc. But never cut the grass. Yet it is obviously cut. Hmmm... Socks |
