i have seen segments on rfd-tv about case tractors, they have chain drives rear-ends, i like there idea. looks like the chains would not strip that easy or chip end of gears.....

Cockshutt 40-50

Case LA has a very big heavy rear end with very large chain drives it should hold up to almost anything. Even that puny little Chevy engine.
Why not get a big block dodge Hemi.

i got a case 2470 rearend if you want that. i got the whole tractor actually but i bet that would work with some mods. have both drive shafts as well.

Cockshutt used a Timken rearend as did Shepherd and a few others, very well built and would be my first choice.

A former neighbor of mine when I lived in Ohio ran a National Tractor Pullers Association tractor called Sassy Massy. It used a Massy 44 rear end (IIRC) and was powered by ~3000hp of two BB chevy 502CID with turbos. It didn't break the differential. Jim

I used to go to pulls and I also pulled. Watch classes with Massey's and Oliver's in them. At the big end of the pull, 9 times out of 10 a Massey will spin-out on one rear wheel. A Oliver will be spinning BOTH rear wheels at the big end. When Dad and I put a poked, stroked and injected Early Chrysler Hemi in a tractor the rear end was a 88 Oliver. We used 24.5X32 tires. This rear end also happened to be a long axle version so be were able to put TWO axle hubs on each axle. One on the inside of the rim and one on the outside. We did not have to worry about busting hubs.

For most or the majority of the multi engine pro pullers used Massey 44 rears. Two reason large tough gear,housing and they were easy to find.
Have had 400 hp in front of the massey rears with no problems but the oliver rear would also work.

that is what im find out most massy are used thanks

terrywh · Jul 24, 2011

is all the massey 44 has the same rear end or does it matter what model you use thanks

The really big tractors use the rear from a 440 AC or the small Steigert. The spider gears are the most important part. They need to be needle bearings. If not check them often, and make sure they are not galled. You need them to work free. not a locked rear. When you see any pulling tractor spin one wheel wildly, you can bet his spider gears are galled. Vic
