Would someone please give me some features, other than serial number, that would distinguish a '41 from a '42 H? Thanks.

Where was the serial # tag located? This helps narrow it down. Also tall or short shift quadrant and 3 or 4 bolts in flywheel side cam bearing? These are things that would be almost impossible to change. HMan

Leon, the short answer is "there are no visible differences between '41 and'42 H's". The long answer is a lot uglier. First of all, out of 23 significant serial number breaks indentified in parts books as to when components were changed, only one or two actually correspond to a model year change. (There were many more changes that aren't listed in the current parts books because the change didn't interfere with retrofitting. That is, if a part changed, but it would still work on the earliest models, that NEW part would be identified as applicable back to the beginning serial number. An example is the hood end cap where the gauges are mounted. There were at least three significant changes in that design, but you can't tell it from the later parts books. The latest end cap, with a provision for three gauges (temp, oil, amps) will bolt up perfectly with the very first tractor, which had only two gauge openings. And, the parts books say the latest end cap applies back to the original s/n of 1000.) And then, you also have to decide what you believe is the actual model year. There is an original list of beginning serial numbers that goes back to 1976, and everybody copied it. Then, around 1996 or so, the beginning serial numbers changed to the "new list". The "new list" is what Two Cylinder and Green Magazine now endorse as "correct". But, a lot of the old lists are still floating around. Changes that actually coincide with new model years are s/n 47796, steel front wheels instead of cast iron. That serial number is the beginning of the 1944 model year (old list), but just happens to be the beginning of the 1945 model year in the new list! S/n 10000, (lots of changes, including a new main crankcase, short shifter tower, 4-bolt left cam bearing cover instead of 3-bolt, etc.) corresponds to the beginning of the 1940 model year (new list), but that was a late 1939 model if you believe the old list. Another possible visible change has to do with decals. Travis Jorde shows different decals for between the 1941 and 1942 models. Travis happens to use the "old list". I haven't had a chance to discuss with him whether he has accurately dated changes against serial numbers, or if he has used sales and marketing data describing "model years". Anyway, I find it pretty useless to describe H's by model years because of all the conflicting information. I'd much rather use actual serial numbers to describe changes.

Leon, there isn't much. There were some changes at S/N 27000 but that was in 1941 so even if we could use that if wouldn't tell a 41 from a 42.
~Does it have electric start?

No electric start nor lights. Didn't the choke operate one way on the '41, and the opposite on the 42?

Leon, you asked " Didn't the choke operate one way on the '41, and the opposite on the 42?". No, the change in chokes with electric start occurred at S/N 27000 & that was in the early part of 31. Even then I'm not sure as I have seen supposedly original later hand starts with the early choke carburetors. The possibility that carbs have been swapped around on those H's is pretty high & to use a carb to determine the date of a tractor is like using a wedding ring to determine the age of a women.

Leon, the DLTX 26 carburator was furnished on serial numbers 1000-26999. The choke on that model rotated down, and had a plain handle. Then, s/n 27000 and later (when electrics started being offered) had the DLTX 46 carb. The choke handle on those units rotated up, and had a provision in the handle to accept the choke knob rod. With electric start, you needed to control the choke while sitting on the seat. Again, serial number 27000 was another one of those mid 1941 model year changes, and does not distinguish a 1941 from a 1942 tractor.
