Re: Deere 4x4 Kinze Repowers - looking for info
Well heck, I can't find my brochure. Oh well. Someone already posted scans of it somewhere in this forum. There are at least two topics about this somewhere; they shouldn't be too hard to find.
As I understand Kinze never put Cats in them; they just used Cummins. The 855 in the 86XX family was rated at 350 horsepower. The 84XX family was 300hp, and the 8850 was 400hp. All of the tractors had the frame extended to fit the larger engine. They also moved the hydraulic pump to behind the engine, then mounted the batteries above that. They topped it off with a tilting fiberglass hood and the option of either a muffler or chromed straight pipe. The front half of the tractor was repainted as standard, but painting the back half and wheels was extra.
I've seen it stressed somewhere (either in the literature or from talking to a rep at a farm show, can't remember exactly) that the conversion wasn't designed to let you pull more than what JD intended for the tractor. It's just to let you pull what you have more efficiently. I kinda think an 855 is overkill for an 84XX or 86XX family tractor. I think an 8.3 or, at most, an L10/M11 would be a better fit. I'm not an engineer, though; just thinking out loud.
Oh, welcome btw.
