I am a very big fan of the older JD crawlers and very much enjoy this web site devoted to these dozers and reading all the questions people have and looking at the pictures that have been sent in. My dad has had several dozers over the years, but he never had a 420 or a 440. I am trying to learn all I can about all the different models and stuff, so my questions today are what is the main difference between a 420 and a 430, which one is better if any and what does the IC and ICD stand for for the 440's and what are the pros and con's between a 440 and a 1010 and which one is better overall. Look forward to the future questions and pictures that people will be sending in.
Thank You, Dan

IC and ICD
Dan,
The only questions I can answer are IC stands for Industrial Crawler and ICD stands for Industrial Crawler Diesel.
I two would like to know the differences between the 40, 420, 430, 440 and 1010. Not much of that is available from my searches of the web.

This will be kind of a long winded answer, but here goes.
There are 3 phases of the 420:
Phase 1, 1956, was the same color as the 40, has more power, and was beefed up in a few areas, but was quite similar.
Phase 2, 1957 saw the introduction of the 5 spd transmission, the 3PT hitch, the two tone paint scheme, heavier clutch housings, heavier finals, different transmission, and a few other updates.
Phase 3, 1958, transmissions changed to fine spline pinion shaft, 55 tooth bull gears instead of 63, and some other minor changes with one exception. The 420 crawlers built after serial number 131,308 used the long transmission input shaft of the 430, and consequently could be optioned with the clutch type reverser like in the 430 and 440. Other than outward appearance and the engine block with the oil fill hole on the block itself, these 420 crawlers were identical to 430 crawlers.
The 430 crawlers were for all intents and purposes the same as the late Phase 3 420 crawlers. There were some minor mechanical changes to the extremely late 430's, but not really earthshaking.
The 440 crawler was introduced in 1958, and was built the same time as the Phase 3 420 crawlers, which is most likely why the production figures for 1958 420's is so low. It was a heavier built crawler, and was Deere's first true purpose built "industrial" crawler. Up to this time, all of the other crawlers were just a farm crawler with a yellow paint job. The 440 has heavier finals and trackframes, full length sideframes that go all the way forward to a heavy cast iron grille, and some integral mounting points for putting on various attachments.
A 1010 is kind of a 4 cylinder 440, they are similar in many ways, but the 1010 uses a completely new transmission, and has a true hydraulic reverser as opposed to the earlier clutch type unit.
Both a 440 and a 1010 have their strong points. The hydraulic reverser is a fantastic option, much faster and easier to use than the clutch type unit. A 1010 gas probably has more power, but has very little torque, and is just not able to hang in there like the old 2 banger, and has a harder time recovering when the load lessens. Parts availability will be better on the 440.
Which to buy is purely a personal choice, and may kind of run towards your taste in the engine dept. If you like the old two banger sound, it is hard to get used to a 1010.
