old JD four cylinder engine

[grwrench]

hello,, deere guys,, a friend told me the other day that JD built a 4 cylinder engine the same style as the 2 cylinder in the A,, B,, G etc.. i assume it was experimental to get more horse power to compete with other makes,, anybody have any info about this???

If by " the same style" your friend meant horizontal pistons and crankshaft perpendicular to the tractor frame, it would have quickly become too wide to be practical in a tractor, even if the bores were significantly reduced.

If it was for some industrial application and size wasn't a limiting factor, I guess it could have been possible, but I've never heard of such. Biggest industrial engine from Deere of that era was the 'W' engine- same as the D tractor.

At the end of the letter series there was a power unit that became a combine engine called an HA 92 I believe is what he might have been referring to. It’s more of a Dubuque engine vertical instead of horizontal. Looks like an LUC but bigger. It was Deere’s first 4 cylinder I haven’t ever seen one in the wild only pictures.

Maybe he saw the one John Kizenbaw built.

hello,, he said JD engineers built 1,, but it made the tractor toooo, wide so it never went into production,, my friend said some one owns this engine and or tractor IF they ever built a tractor around it..

Urban legend , just like driving down a back road and finding a Harley Davidson for sale that Elvis used to own .
Deere did have 4 and 6 cylinders for the 1957 model year . For use in Combines etc . I wouldn’t mind having a couple of the gas six’s from the 105 .
They used the weird sleeve deck design .

I believe Hart Parr made a four cylinder horizontal opposed. Maybe that's where the confusion comes from.

I could see the JD research department creating a four cylinder by expanding the small vertical two cylinder engine like what is in my 420S.
A four cylinder based on that engine would have fit under the hood with room to spare in a 420.

You are describing what Deere did to build the 1010
