If your ground is pretty mellow then one of those drills would probably work, if it's concrete then they tend to be too light and will ride out on the disks. We had a bigger brother to that, a 2n3010 for our spring legumes. Weighted on the outside of the wings, sometimes in a firm spot and the drill was almost empty they'd ride out. It's the same lead coulter design, different seed opener set up though. Our seed openers had a parallel linkage design with poly and steel bushings, I believe it had over 5000 acres when I replaced all those. Check for any broken seed cups, I never dealt with that but I think you have to pull the entire shaft to work on one. Drive chains use plastic idler sprockets so those don't last long. Seed flutes were never an issue, the tabs that hold your feed cup bottom in place would get brittle over time, replace every 5-6 years. They're cheap though, 3 or 4 bucks I think at the last. Check the vertical straps the lead coulters are mounted on, if a bunch of them are bent back then you'll probably break a few. The springs are being ran too tight if they're bent back. Side to side play on the openers will tell you how worn out the opener bushings are. Near new you shouldn't get over 1/4" to 3/8" play over all side to side. They adjust depth easily, I never lost a press wheel bearing either. Unhook the seed tubes at the end of every season, they tend to stretch and will kink over and plug if left tight all year. Drill was a rental before we got it so that's an estimation on acres. I wouldn't call it troublesome, it's like anything mechanical, eventually you've got to replace parts. I never thought ours was hard to work on, grease every 200 acres. If your fields are pretty irregular in shape then I'd recommend the pull behind, the 3pt turning all the time will work anything that pivots more since it'll be trying to shear sideways vs tracking true behind your tractor, side shear is harder on everything and wears things prematurely. We seeded everything from CRP to garbanzos, it was our primary spring drill. If you're not going to be seeding through ponds and pure mud I do know JD makes a 10 ft 750 that would seed those crops as well. One thing we consider when looking at equipment is parts availability. If you've got a GP dealer 5 miles up the road and a Deere dealer 70 miles out, you'll either have to get your own parts inventory or lose seat time if you go JD.
