I've stumbled across their site as well. It looks like handy stuff but it's insanely expensive...it seems like a recipe for debt on a small piece of
land, which is a step away from self sufficiency. Other than that, I don't think you're out of your mind at all
How much land, how many animals? There is a lot of fifteen to fifty year old farm equipment out there that is functional and tough and can be picked up really inexpensively as it's too small now and Big Ag can't use it anymore. If you have enough acreage to use it and store it, I'd go that way. An old self propelled swather can be less than a grand...if you take care of it it'll last a long long time as you'll only be running it a couple of hours a year. Depending on climate you could then swath graze with electric
fence. Or pick up an old baler too and make greenfeed (harvest while the grain is still at soft dough stage) The horse people have kept prices high on old square balers though.
On a smaller scale a scythe would be a lot simpler and more economical than the italian machines. I am scything oats right now and hand tying sheafs. They are getting piled in shooks for now, and i will probably bring them in and stack them (heads to inside) on some
pallets and throw a tarp over. Yes it will be a
mouse hotel. Yes it's quite a bit of work...not a problem in itself, but there is a narrow time window and it seems like everything needs doing at once.
I'm thinking the quinoa and amaranth would have heavy seed losses if they were ripe. Not sure what feed value they have if you put them up while they are still doughy, I've always thought of them as people food. I am also scything some hulless oats for people food and I'm losing some...I think I'll stick to hulled varieties for feed.
Have you grown flax? I tried this year and it was a disaster...my fields are not nearly clean enough to even consider it yet, they came with a crazy weed seed bank and the flax can't handle it. Oh well, lesson learned.
