But if I think of it in terms of a foot-clutch tractor it seems to make sense: If I parked my Farmall M with the engine running, I'd put it in neutral and let the clutch out. So on a JD two-cylinder I'd want to conceptually do the same thing: "let the clutch out", which I think would start the belt pulley turning as Ron says.

Hi Dean:
I never "engage" the brakes. I always "apply" the brakes. :-)
You "engage" the clutch when you connect the input shaft and the output
shaft so they turn as one. This is also (at least in the olden days)
known as "throwing in" the clutch. Sometimes placing the transmission in
a gear is also called "throwing it in" gear.
"Throwing out" is used for disconnecting a hand clutch but not normally
a foot clutch. You "disengage" or "depress" a foot clutch. Sometimes
you "yank out" a hand clutch. You can also sometimes "yank" a
transmission out of gear but I have also been known to "pop" a
transmission out of gear. Maybe that comes from the fact that most
transmissions are held in gear by "poppet" balls being pushed into holes
in the shift rails. :-) Some folks "kick" a transmission into or out
of gear.
In a tight location you must "slip" or "feather" the clutch...
A John Deere hand clutch will normally "feather" very smoothly. That is
not the case (Case also used hand clutches a lot) with my MM-R hand
clutch. It is very jumpy (sensitive) and, according to a neighbor of my
uncle who bought it new, it always has been.
I don't have it handy but I believe the owners manual for my 1948 John
Deere A says pretty much what Ron said.
I became "engaged" to Diana about 46 years ago. We became married the
next year, we did not become "disengaged"... :-) We "clutched" hands
a lot and she wore the ring on her hand so I guess that was... :-)

I wouldn't mind being absent minded so bad if forgetfulness
could just be a little more selective. Just last week I
was saying so to "whats-her-name..."
