Yep, it’s the MX, and is the GB70 deluxe. Deluxe means you get the sweeps and furrowing attachment. I would mention My QH20 does not dock to the GB without modification (I think if I find a long enough pin I might be able to make it work, but it is not intended for cat 2 QH…EA told me that when I called to ask them about it pre purchase…they were helpful. I would also mention have a back ho subframe, and the link arms when set to dock to the GB has only about 1/4 a 1/2 inch clearance to the subframe….where I work a mm is a mile, so it’s fine but it’s close in my mind for something that has some sway to it. There were no assembly instructions but its very easily to figure it out. The GB is very well made (heavy gauge material…The welds aren’t very pretty, but it’s fine in my mind. I was really surprised how well the sweeps did…I’ve only ran really large stuff…actual farm stuff for friends, so this is is like a matchbox toy compared to that but it worked well and was fun like playing smash up cars. It was so much easier than hilling potatoes by hand or a wheel ho…in the first pic above I used the wheel ho…the finished pic was after the bedder. We have a clay type soil up here and the bedder was awesome. I sort of wish I had a smaller one now for my B at home (the pics are at our other place). But for money I can put it in the truck or on a trailer. It’s not something I want to lift into a truck by myself though…it’s not thin material. I would likely need to adjust the sweeps to put on a smaller machine. I am not sure my B would lift it high enough either to drive around, but maybe it would be fine? Next year I would plan to use the furrowing attachment to leave the furrow for planting…tractor was out of commission from an oops the day we planted so I used the wheel hoe for the furrow and to cover the cover the potatos. Overall I am very pleased. Compared to doing by hand or with a wheel ho it’s really helpful. A wheel how could in no way make as wide or as tall of a hill. There is no comparison there. I set the sweeps so that they are dead center of the tire track. I think with an Mx a GB60 would be fine however you would lose some adjustment room. I think the 70 is correct for a 6 ft wide tractor and the sweeps can swivel in or out if you so choose. With a 60 if you wanted to make a wider bed I think you could run out of room maybe? But I am not sure. I did not adjust the discs beyond my set up as they did what I wanted to do but that would sort of be the question I think is how wide and how to configure the discs for a raised bed….I did not try so I can’t say…I do know that I pushed the 3pt down to far in one pass and covered up more than I wanted. It would do great to create any sort of raised beds I think. It’s just trial an error. If you have any questions or want any measurements let me know. I hope this helps.
