This is a 1940 model as is evidenced by base mount mag and inline generator, as well as 6 bolt rear wheels. Case made both CH and CC4 as well as DH and DC4 with 6 bolt wheels. It did not have anything to do with sliding axles. If the dyno operator did not pull the engine down further, it is likely because the power was already dropping off.

i think this is a 1950 DC-4

That is a straight model "D" being that it is an early one. Also the guys running the dyno should have put more of a load on the tractor. If you listen it doesnt even pull the engine speed down. I have a DC that has the bigger 4 inch pistons in it and it dynos at about 40 hp.

Don't think Case called these DC4's in 1940, more likely is a DH. DC4's had the sliding rear wheels like the DC's (what use that was I don't know since the front axle was fixed on them).
