Any idea what the contraption is at the front of the tractor, below the radiator?

I don't know what the Europeans call it, but I would call it the cylinder head. For the huge single cylinder behind it.

That is a hot bulb engine sometimes called a semi diesel. The head must be hot to run and will not will not start from cold unless the head is heated or a starting wick is used. What you are looking at is the cylinder head. At the top is the fuel injector. The tee handled plug in the middle is where a starting wick is lit on fire and inserted. Partially visable at the bottom is the hot bulb, this can be heated with a torch to start the tractor. The engine does not have enough compression to ignite the fuel. The injector introduces fuel to the hot bulb early in the compression stroke where it is turned into steam. As the compression comes up the steam is ignited by the extra heat created.

Thanks for your explanation, Butch. I assume it had to do with the hot bulb engine; I didn't realize that it is the actual cylinder head.

They are interesting engines, I own 3 of them. Most were 2 cycle like that tractor but there are also 4 cycle versions. They were mostly a European deal for unknown reason but there were some built and used here, mainly very large stationary engines. Fairbanks Morse was the primary builder here.

Here is a video of the Lanz start up. Usually there is a proper blow lamp thet goes in a holder under the head. On the HSCS you can see the elbow where it fits, with the paint burnt off.
