I had 2 Case 830 COM, I liked them. I had a 2010 JD gas. It wasn't the best loader tractor. I think the Diesel engine was the problem, not used in anything else. The gas engine was always needing some tuning but the rest of the tractor was no problem. I went to a 2020 next, then a 2030 for loader tractor. We used a loader tractor a lot, and pulled a sprayer with harrows for Avadex on wheat. Unload flex harrows off wagon, set side by side and attach to wheel booms. Tractor pulled wagon, sprayer hooked behind, wheel booms trailing behind, down the road. I never liked the 2010 transmission, even on 10, 20, 30 series JD's. I would much rather the 2 stick German transmissions. I had a 1010, it was different all together. Never had a problem with it. It had a 3pt. fork lift on it, toting filbert boxes. Seemed built more like a JD 40 I had for running grain augers.
I didn't mind the chicken roost steering, gave a lot help to make steering easier. Grew up on a DC with a wide front way out there. A DC 4 die seem to steer OK though, turned much shorter. I had a 300. Dad had a 400. I got a 430, loved that little tractor almost as much as the 300. Had 2 830's, a 770 and a 870.
Dad was all IH but when he wanted a diesel, he knew he did not want an IH. He had a TD-9 and it was a mess to keep running, many cracked heads. He bought a slightly used 400 Case with a Case trip loader, traded a Farmall M with an old pipe loader. We had a great Case dealer+ they sold Oliver and Gehl forage equipment, Bear-cat hammermills and flail choppers. Dad stayed with case, 00 series to 30 series until he bought an IH 706 used. His last tractor was a Farmall 1256. He did not want a 70 series powershift. I liked the 2 range 8 speed Case transmissions but would have been nice to have 1 gear up or down, without clutching, but it was best they didn't make one. I never got the need for so many gears, I sized the machine to the tractor but a high low to split a gear in the tough spot or at end of row was really nice. Like Massey and IH had. But never liked the TA on the bigger tractors. I did have a 504 with the old TA, worked nice with a loader for a faster reverse. I just took that all the way to the JD 8 speed power shift, Never liked the 15 speed. Guys were always trying to shift up one more gear, but just wouldn't quite pull it. Gears were just closer together for more shifting, up and down. One gear was enough with the 8 speed most of the time but needed 2-3 on a 15 speed. 8 speed I just ran right there in 5th, perfect for speed and the equipment of the time, but could shift down without clutching....James
