Fella I know has a7580 Allis, that he no longer needs , and would like to part with. Are they any good? Are there any parts that give out , and are no longer available? Did they have an Allis engine , or some other Diesel? Real interested to learn what I can , as this looks like a cheap tillage tractor , but I know nothing about them. Any , and all input welcome ,Thanks. Bruce

I have no experience with them. Hopefully someone will come along who has.

The engine is the same basic engine in the venerable D21, pushed as far as they dared, I guess. They got a power rating with speed, which doesn't excite me.

But if you know the owner and the tractor, that would mean more to me than anything.

Best of luck.

Worked on a few of them back when the were still fairly new. Weak points I remember - engine, for openers. Hopped up 426 ci. with high RPM, extra fuel, turbo, intercooler, piston coolers. Not known for great lifespan as I recall. Pivot joints were a problem as well. Then the famous PTO driveline. Poorly situated(in my opinion) with a CV joint directly between the pivot joints and operating at 2700 RPM. Even with frequent greasing, they had a limited lifespan. They were around $1200 or so back then.

I'm sorry too. The engine speed SHOULD be more like 2250 or 2300, but that's not what the "engineers" decided. Rated speed at full load is 2550, and high idle is 2750.
