Here’s a quick walk around of the tractor.
I’m very happy with how good of shape it’s in despite its age. A few little things to cure, but over all, excellent shape. I can’t wait to get the loader for it! You can bet I’ll be researching these forums to figure out how it goes on

The shift decal is accurate, it duplicates numbers cast into the top of the transmission.

The decal looks strange but that's because top gear in each range is 'road gear', much higher geared than what you expect for normal intervals between gears. In low range, shifting 1235 ends up in a higher gear than the lowest gear available in high range. Its intuitive while operating the tractor it just looks funny.

My issue is with 5th gear being in low range and 4th gear being in high range.
It seems overly strange that to go from 3rd to 4th gear you would change ranges then to go to 5th gear from 4th you go back to low range.
There is no mechanical way to get 2 separated gear speeds without changing ranges.

No, you stay in high or low range.

Maybe this describes it better: You use gears 123R for whatever you are doing. 5/8 is much higher, its only for when you want to zoom over to another location to work on something over there. Especially in high range, 8 is the 'road gear' for maximum speed going down the road. It's geared too high to start off if you are pulling something uphill etc.

You never need to go 3 to 4. These have so much torque that it doesn't make much difference if you are one gear away from optimum. The lower gears are mostly for choosing a suitable ground speed.

On last point: This is a severely non-syncro transmission. Every gear selection must be done at a full stop. You choose a suitable gear for your project. Then you start off.

The decal looks non-intuitive but operating the tractor it all makes sense.

Kinda funny.
I didn’t even notice the weird shift pattern on the decal or casting.
I just glanced over it for 1st, 2nd and reverse.
That was enough for me to get an idea of its pattern.
Shifting it was intuitive.
1st, 2nd, 3rd, then apparently 5th. ��*
I’m sure with implements on the machine, and I was trying to achieve a specific speed, I Would have noticed the odd placement, but the machine speeds moved as I expected in each gear.

Sorry CA, but you contradict your self!
It is a 4 speed transmission, use 123R, never use 3
5/8 to get there quick.

Bottom line you agree that the shift pattern is screwed up. Perhaps by a factory engineer, but none the less screwed up!
Shift pattern suggest 1-2-3-5-4-6-7-8. Seems like a screw up to me. For an 80’s model tractor that kind of counting was wrong!

You're simply wrong.

To begin, the parts manual says for 1975 and later.

I use high 3 probably more than any other.

Everything else.

You're thinking like in an automobile where you go up through the gears sequentially as you gain speed.

With no syncros in these, you have to start in every gear from a standstill. You select an appropriate gear for the task then go. There's no reason to shift 3 to 4 like you would in a car.

I am quite aware of how a non sync tractor transmission works than you kindly. And how else do you label a 4 slot transmission with Reverse than either as a 4 speed/2 ranges or as 8 speed within 2 ranges (half dozen of one and 6 of the other)
It is also not logical to have “5th gear” slower speed than “4th gear” even it the tractor world.
You seem to be stuck in a rut and continue to contradict yourself. In a previous comment you stated ‘don’t use 3’ and now you say you use it most!
Are you by chance the engineer that designed that mislabeled transmission and can not as mist engineers admit an error?
Can you at a minimum agree that the same slot in the transmission can not have 2 speeds without changing ranges?

In a previous comment you stated 'Don't use 3'

I did?

Plonk.

Plonk.

You did! I went back and reread what was printed before typing the statement!
