The 440 and 435 Series
I can always use help, email me with any information.

First the 440, if you want to go down to the 435, click here.

The 440
The 440 was built from 1958-1960. It was the first John Deere tractor designed from the start for industrial work.

It had a total production of 21928 tractors(according to an old posting). Not rare at all, but that means plenty of parts are avaliable.

Pictures of 440 Crawlers are here.
Pictures of 440 Wheel tractors are here.
I have heard that the 440 was produced into the 1960s, till about 1963. I don't know if this is true, but it is very possible, since the New Generation industrials weren't really produced until 1961. If anyone has more information about this, let me know.

The 440 was made in a few versions:
440I (Wheel Tractor-Gas) 2341 made.
440ID (Wheel-Diesel) 971 made.
440IC (Crawler-Gas) 9845 made
440IC (Crawler-All Fuel) 10 made, I'd say it wasn't popular!!
440ICD (Crawler-Diesel) 6679 made
440 Serial Numbers

Note for people with a 440 gas tractor: In the early 440s the gas engine was the same as the type used in the 420s. At serial number 448001 the gas engines of the 440 were modified to produce more power. The rated RPM was raised from 1850 to 2000 and the compression was bumped up with a new cylinder head. The 420/430 (which used the same basic engine) never recieved these improvements.

The 435
Built from 1959-1960
The 435 was an attempt by Deere to get more diesel engines into the agricultural market. The tractor was based on the 440 frame and a GM 2-53 diesel engine. Although it was supposed to be for agricultural applications, there were some industrial tractors made.
A total of FOUR were made.

Their Serial numbers were:
438582 (equipped with a four-speed transmission)

The only difference from the agricultural versions was an industrial yellow paint job. The above serial numbers had a Custom Job number 265 (C.J. 265). If anyone can tell me any other differences, Email me. Do any of these still exsist? Are there any differences I don't know about? Email me!

I couldn't have included the 435 without Green Magazine.
