That’s just cruel.

That looks fun.
One of Russian trucks that Finnish military used to have also had a
somewhat
confusing shift pattern. I think it was:
2 3
1 4

IIRC from a RCR video some military truck (deuce and a half?) had something like
R 2 5
1 3 4
With 5 up left on a dog leg because it was a front bench and if the gears were in the “proper” order nobody could sit in the middle seat too long

That’s nothing. My dad had one of these:

That pattern is REALLY common with big trucks. Almost everything heavy duty has reverse up to the left, with the low gear just below. Unless taking off with a heavy load, that gear is normally skipped, so it is shifted like a 4-speed. Big rigs with 13-speed and 18-speed transmissions will use the same pattern, just with ranges and/or splitters to multiply the total
number of combinations.

A lot of the old “twin-stick” big rigs had a U-pattern like that (usually flipped over) for the auxillary transmission.

The Soviet Union borrowed a lot of designs from the US so the idea came
probably
from these.

I’m assuming there’s a reason for having 3rd off in outer space but for the life of me I can’t think of one.

I believe the way the internals were structured, those transmissions were really 3 speeds with a hi/low range. Moving the stick from the left side to the right side switched the range selection. But, top gear in low range was taller than low gear in high range, so 4th gear is on the low range side and 3rd gear is on the high range side.
The good news is that with straight cut gears and a hand clutch, no one was going to be shifting that on the fly. Like most tractors, you stopped, selected the speed you want, and then take off.

Right, I know a dog leg granny is pretty common. But I was more surprised by the 4-5 flip.

I learned to drive on one of those! 2 cylinders for life!

2 cylinders for life!
Those old 2 cylinder motors were pretty neat. Lots of low-end torque and nearly impossible to stall. The big diesel versions were scary strong.

They were practically all my dad used on the farm when I was growing up. My first word as a baby was “putt-putt”, a.k.a. the sound a 2-cylinder makes. I love the chugging sounds the diesels made, though! I’m going back to Minnesota this August for the Butterfield Thresherman’s Association’s annual Steam and Gas Engine Show. It’s my favorite thing in the world and I probably haven’t been in nearly 15 years. So many vintage tractors!!!
This 720 was the main workhorse for years and years. Never thought the old man would sell it, but he did a couple of years ago. I sure miss it.
