A Diesel. Riiiiiight.... After you. Bring friends.

International UD9 - got one - it crank starts just fine with one person
jumping on the crank.

Google "Lanz Bulldog" and "Field Marshall" tractors.

The early Cat scrapers were hand cranked - the small
gas pony motor that is. It was then run for awhile
to heat up the diesel then clutched in to start it.

The UD9 is more interesting. Diesel injectors, spark plugs, gas carb,
switchable compression ratio.

There was no starting them by hand though. They were the same set up as the
early IH diesel tractors.....they worked but there was a better way, as
Oliver proved at least in the farm tractors.

Baloney, I've started a UD9 by hand a number of times and it works fine.


I've heard of a lot of the dodges used to get antique tractors and
implements running. While it is possible to hand-crank small diesels
in the Under 10 HP range (Hatz has several one-lung horizontal shaft
engines) anything bigger you start playing with multi-fuel, and pony
engines, and compression release shifts, and lighting a big wad of
newspaper in front of the air inlet in lieu of glowplugs, and other
dodges old and new...


The UD9 is ~50 HP, and indeed has the multi fuel and dual compression
ratio. Pretty neat really since there are no glow plugs and if you were
to bypass the diesel shutoff solenoid you don't need any electrical
power to get it started.


Not all that safe, not all that reliable, and while a technically
inclined person could do it no problem it certainly is not something
you want your wife or mother trying at 3 AM in a snowstorm.


Seems safe and reliable on the UD9. As for the later issue, anything
short of a "start" button on the wall in the house tends to be a problem
there.


That's the time you need something roughly as simple as driving a
modern car, or someone is going to get hurt.

It needs to be all hooked up and ready to go, and easily done
following a short checklist.

And shutdown is the same in the reverse.

A fully automatic start and transfer switch would be ideal, but you
can't turn a housewife into a competent field engineer. So you have
to pick one that doesn't involve Technical Stuff like swinging a dead
chicken over the engine (Counterclockwise only!) to get started.
