The biggest improvement over the 8Ns , other than HP, was the live hydraulics. the 850may or may not have a live PTO, depends on the clutch setup too.
I thought the square fronts were all live PTO but not real sure about the 3000 with the Sherman in it.

The V8 in the 8N was a joke. A 60hp flat head in a 30hp tractor was not a good combination. either the trans or rearend went to shit in a hurry if you tried really working it.
Started with nothing and still have most of it left.

What do you mean by live pto? If my 850 pto is engaged it's on no matter what gear even neutral, but goes away with clutch

Here's what I found on the live PTO:
Live PTO Explanation. ... A live PTO, normally, has a 2 stage clutch. You can depress the clutch 1/2 way in and the transmission will stop but the PTO will continue to spin under a load (not just free spin). If you depress the clutch all the way the PTO will stop also.

I think that the 850 had a 4 sp. transmission and the 860 had the 5 sp.

The 5 spds had the option of being a 2 stage clutch or not. The clutch arm has two holes in it. one allows the pto to run while the tractor stops, the other has the PTO stop whenever the clutch is pressed.

The old guy who set up my 800's 2 stage clutch recommended leaving it as the 2 stage clutch.

Like he said LIVE pto(and/or hydraulics) is pto that keeps running with the clutch depressed.

Cockshutt was the first to have it.

Most of the early model were 2 stage clutch like stated. Later on they were hydraulic clutch pack applied.

5spd may have a 2 stage clutch. look at your clutch arm. does it have two holes?

What is the number on the bell housing? an 850 is 5speed no live pto. 860 has a live pto.

I think it's an 860, cool.  Not sure it really matters as I use a rotoriller and a bush hog but nice to learn.
