The tractor has 25 PTO horsepower, about 30 engine HP. There are many low gear speeds (1st Low is verrrrry slow).
I mean, I guess the cheapskate option is to scythe everything (I already have a scythe), and if I need the material on the beds chopped up more, I can use the landowner's lawnmower after it's died back for a couple days. It's just that everyone who's knows anything about cover crops for vegetables agrees that flail mowers work the best for chopping it up into even-sized pieces and not leaving windrows or scattering everywhere. Some people just moldboard plow it in, but I've read The Plowman's Folly. I have a chisel plow that will get caught up in the trash easily - it needs everything chopped up. And obviously there's the all-too-popular herbicide method, which I will not do.
The Caroni website actually was more helpful than I expected, showing the hydraulic shifting positions. I'll need to go out and measure again, but it looks like having 800 mm sticking out from the PTO shaft still might be a little too much. Only the TL1200 (48") has a shifting position that allows less than 800 mm sticking out. But it's still gonna be wonky with only 450 mm being cut on the other side of the PTO shaft. *sigh*
The weed badger... does not look like the right tool for the job. Yes I can see how it would be useful maintaining fencelines and orchards. But I don't need to spend that much money on something that only maintains my fencelines. I don't see anywhere on the website where it explains how wide the tiller is, but it looks like it can't be more than 12 inches or so, so to till the whole bed would require multiple passes.
The
woodmaxx looks like it might work. I will consider it. It's too bad that flail mowers, and specifically flail mowers less than 72+", are not more common used/craigslist.
I like looking through the Italian agricultural websites, thank you for those suggestions. It looks like Maschio has an American importer in Iowa. Not sure if Peruzzo has an importer.
