This is what mine looks like, pulls very easy with my Craftsman. If you turn them out you can tear down rows. I was using a screw jack with a power window motor to lift it at that time. I have now replaced it with a $49.95 winch from Harbor Freight. Works Great!
I used the KK middlebuster, Lowered down, make a trench, come back in the other direction with the front tire of the tractor next to the soil raised up from the trench, it makes like a W. You just nock down the tips ow the W , with a sweep of a garden rake. I did see a Bed Shaper by Buckeye tractor co, looks nice.
I've been making and sell this Disc Hiller locally. It takes the work out of gardening.
I posted the wrong pic of the beds but can't figure out how to remove it. It does a similar job of making beds.
I bought the 2 gang assembly with brackets for $250.00 from Stevens Tractor Co. 800.333.9143. I added the toolbar I got locally and also the sleeve hitch.
With shipping I have about $315 tied up in it. If you call they will send you a catalog, they have tons of stuff and most of it they build themselves.
If you check with some of the big farms in your area you can locate some old 4 row equipment real cheap. I got an old john deere 4 row cultivator with the guage wheel and cut the tool bar in half and moved each gang of harrows down to make it a two row to go behind a 75 horse tractor. With that size tractor you would lose alot of garden space with a one row. I use small sweeps on the back harrow to make my rows, then when I cultivate or lay my corn by I just put the big sweeps on the back and it makes the rows bigger. I have mine set at 32" centers. If you want some pic let me know. Most of the 4 row equipment can be had a local equipment auctions for less than $200.
What a great thread to find! I wanted to build this with plate, rather than a rotating disc, to form each side of the hill and create 2 hills at a time. Now the disc makes so much sense, esp. if your depth of loose soil varies as the plate model would see some pretty hard work if you went below the tilled/plowed/harrowed soil.
Most of the ones I see here are single row - 2 row should be easy enough, no? Dirtydusty - you suggested taking a 4 row and cutting it down?
I think back in the 80's 4 rows where the thing, now they have 21 row equipment. Most big farms have these laying around in the weeds. you can also find some old 4 row planters that you can do the same with too. There is 6 and 8 row equipment available, but they are more expensive.
