On our 806, 1256, 1086 IH, 2590 Case, 8630 and 4450 John Deere all have ether as a start assist. Nice can holder under the hood and a button on the dash. Get the engine spinning over and give 'em a sniff and they always fire up. I'm not sure what the latest diesel tractors use.
Glow plugs, pony motors, and start on gas diesels were necessary because of a couple of things... 1.) They did not have enough compression when cranking to really ignite the diesel fuel. They were around 17:1 while newer diesels can be up to around 24:1 2.) Their injector pumps did not develop enough pressure when cranking to really atomize the fuel - also partly the fault of the injector design. Old injector systems were around 2500 to 3500 psi - new injector systems run near 25,000 psi on a common rail (maybe higher?).
The technology for building engine parts that hold up to the stress of high compression and high fuel pressures and also the accuracy of fuel injected is the reason the newer diesels start better, and run quieter.
I can tell you this much, my brother's 98 Cummins has the intake manifold heater system that kicks on when you turn the key on no matter what the temp is. It will start down to 35 below zero with no other assist.
His 06 Cummins won't even kick on the manifold heater until it's down around 5 above. I don't think he has plugged it in unless it gets below zero, and I doubt he has tried to start it unplugged at as low of a temp as the 98.

Today's Featured Article - A Lifetime of David Brown Tractors - by Samuel Kennedy. I was born in 1950 and reared on my family�s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
