G and GM differences

[clampdaddy]

I have a styled G but I always liked the looks of the pan seat of the GM. I've thought about switching mine over to a pan seat but I got to thinking, did any pan seat tractors come without embossed axle housings? If they did I'd consider doing the swap even though it wouldn't be "correct" for the year of my tractor, but if it wouldn't look "correct" at a glance I wouldn't want to do it.

The generally accepted serial number break for the elimination
of "John Deere" on the rear axle housing is 26,000 up, July 30,
1947.
As explained in the Nov-Dec issue of Two-Cylinder magazine,
page 42, eliminating the embossing was coupled with a
domino effect of engineering changes which included the
battery box seat, different platform, and changes to the power
lift housing, to name a few. All covered in factory order C-
9933. These decisions were made in view of the upcoming
"GN", and concerns about front end stability.
Yeah, I really like GM"s too.

Yes there were a few in 1947 after the GM that carried the pan seat, that were authentic G"s.

So I'd need a new rear end cover for sure. Will the platform from an A or B work on a G?

The GM Series was in production from 1942-1947 with a serial number range of 13,000 to 22,122. The G Series started in 1947 with serial number 23,000. However, the same configuration was retained until serial number 26,000 when the battery was moved under the seat. This small window from serial number 23,000 to 26,000 created some of the most rare G series tractors. GN only 47 were built; GW only 120 were built

My G is a 1950 model and it has a tool tray between the valve cover and the radiator. Was the same tray used for the batteries on the earlier pan seat models or was a larger tray used?

Deere did not install a tool tray on the Gs. they had a tool box much like you find on 60s and 70s it mounted on top of the crankcase you must have an old battery tray on there farmer riged

If the tractor is a 50 model the only item in the frame would be a tool box. The GM battery set up is easy to identify by the lower water pipe. The late model water pipe is round. The water pipe on a GM will be flat and almost twice as wide, other wise it would not have cleared the battery tray.

Mine actually does have the flat lower pipe. makes me wonder if Deere used some old left over parts on my tractor. I seriously doubt a farmer would go through the trouble to change that lower pipe just so he could install the tray. I sure wish these old irons could talk.
