trivia question

John Deere D. Trev.

I'm going with, dang I hate to even say this, but the IHC T-6 and TD-6 they where built from 1940 to 1969if I did the math right that's 29 years. Yes they where sold as farm tractors back in the day.

Fordson had the largest number of any one model . Fordsons Model F Made in US 1917 to 1928, Total...........747,681 units. It just took JD 30 years to figure out they were still building new antique tractors

That Fordson put many tractor companies out of business because it sold for $375 a unit where the makers of much bigger tractors were trying to get a few thousand per tractor.

While Deere made the D for 30 years, I'm sure there were enough significant changes that most parts for the last one didn't fit the early years. They had troubles with the early flywheels and many were updated in the field.

Deere had a tendency to keep the same model number though lots changed. I know there were at least 4 versions of the 4020 op manual, and two versions of the parts book and shop manual. The side console 4020 shared so little with the early 4020 that they had the separate books. In the preside console 4020 there were three versions of the operator's manual because of changes in how it was started and changes from oil to dry air cleaners and probably several others. For sure the wiring harnesses changed at least three times. The side console 4020 moved the remote hydraulic valves from the dash to the back of the tractor and the controls from the dash to the side console. Almost nothing in the hydraulics was the same in the side console version.  Diesel engine parts from the later version will go in the early block but its hard to start because the late block was a quarter inch shorter than the early block and that hurt the compression ratio.

Farmall Cubs were sold for a pretty good while.

Gerald is right. The R, A, B etc were vastly different from the early to the late models. Almost nothing from an early A will fit a late A and so on.

Take a WD and a WC. Virtually every thing from a WC engine will fit into a WD engine. Same with most of the sheet metal. Even the tranny gears will swap but the WC's had softer gears than the WD or late WD. Not sure when the harder gears were put into production but they'll swap as a set.

To me the A and B Deere should have each been renamed into 3 different models. While the WC, using Deere's model designation philosophy, could have remained a WC into 1957 and never ever used the model designations WD or WD45 for that matter. That would have given the WC a 24 year production span with well over 400,000 units produced. It would have been more justifiable than the Deere model A, B or D production designations.

We Burnett's have to stick together!
The Farmall/International Cub ran from 1947-1979
