Can Someone Explain This

Yup. Starts with a blank shotgun shell. The thing he lit and put in the front was to provide hot air to the engine to aid in starting. Then he smacked the firing pin on the shotgun shell to provide a charge of compressed air to spin the engine over.

It's a single cylinder diesel. You're not going to hand crank a diesel, even an old low compression one like that. They didn't have an electric starter that could spin a diesel over fast enough to start either.

A famous use of shotgun shells to start an engine is the James Stewart movie "Flight of the Phoenix." There the shells were used to start a radial airplane engine.
 
You can hand crank them, I have done it many times. My father's
boss bought me a Field Marshall to drive to cultivate and plough
stubble after harvest, during the school holidays. Spent many
happy hours in the seat and coming home with Marshall Measles
from the oil spots coming out of the exhaust. They have a
decompressor that is automatically release as you get up to speed
with the handle.

Cartridge is a bit more powerful than a shot gun shell although
it is the same size. It is full of tiny round sticks of grey
colour. I was always told it was cordite but I do not know for
sure. I only know it goes off with a massive bang and knocks you
over if you inadvertently put one in a shotgun.
 
From Wikipedia
The Coffman device used a large blank cartridge containing Cordite that, when fired, pushed a piston forward. A screw thread driven by the piston engaged with the engine, turning it over.[2] This was in contrast with other type of cartridge starter which acted directly to drive the engine piston down and so turn the rest of the engine over, such as those used on the Field-Marshall agricultural diesel tractor.
 
When I was painting ships they would use a 1/4 stick of dinomite to start the engines, I was up 3 stories on scaffolding on a 4x8 barge one time they did it scared they bejeevers out of me
 
I have 2 series 3 field Marshalls and a Fowler VF. All 3 start with a cartridge. The load is a small amount black powder in the bottom of the shell then nearly fill the shell with a slow burning rifle pellet.People are amazed how quick it starts when you fire the shell. It crates a lot of interest at shows.Not many in our part of the world here in Kansas.

The guy was standing in the line of sight when he put the shotgun shell in at the beginning of the video, and the guy taking the video was pointing at the Ford in the corner at the time. Sometimes a "dress rehearsal" helps, figuring out where to stand, etc.
 
That one must have already been running and warm, it's usually a real ordeal to get one running! I've heard it was not good to use the blank cartridge, it put residue in the cylinder that could damage the rings.

There was also a "hot bulb" starting method on a similar model.

It involved heating the cylinder head with a blow torch.

Once hot, the engine was hand cranked, either with a crank or the steering wheel!

Looks like it starts on the compression rebound, not cranked all the way through.

The engine will run either way, no reverse in the transmission, the engine is stopped and reversed. Look at about 0:47.

They all have that type muffler.

I think it's more than just a muffler, it's some type expansion chamber, extractor. It must be necessary to run, never seen one without it.
 
As Majorman said you start them on the handle like a proper Marshall man would. You would also wear your Marshall overalls and not your Sunday best light blue shirt. Big following of Marshall men here in the UK and I live only 15 miles from were they were made at Britania Works Gainsborough. MJ
 
Must be better balanced than most of these poorly balanced old engines in the states. It just sets still while running not bouncing like a lot of those old deere do when idling.
 
"I only know it goes off with a massive bang and knocks you
over if you inadvertently put one in a shotgun"

I had to laugh because I tend to think it wasn't an inadvertent accident!

The original British Canberra bomber (US b-57 later RB-57) was started with black powder cartridges. Many engines were destroyed at starting because the fireman standing by thought the engine was on fire and doused it, Korean War stuff
