John Deere Firsts

[Ted in NE-OH]

I am writing an article for my club's newsletter . What are some of the firsts that John Deere introduced?
 

[David G]

None until new generation.
 

[Greenday]

Roll-a-Matic front end

The modern telescopic PTO shield first introduced on the No8 mower. Exploded parts illistrations introduced as part of the war effort during ww2. Both of these were unpatented because they felt the industry should adopt them as soon as possible.

Good grief, the steel plow!

Don't forget the obvious, the self scouring steel plow.

Then there was the Gilpin Sulky Plow that took the farmer off his feet and into a seat.

In 1980 JD introduced the 4 row cotton picker, an industry first.
 

[Roger in Iowa]

Hay Cuber, both self propelled and stationary.

I believe the GP was the first tractor with power lift of any type.
 

[NY 986]

I think the 435 might have been the first tractor with dual speed PTO.

A Deere book I have claims the Model A was the first tractor with adjustable wheel tread. I can't say whether that is accurate or not, though.

Closed-Center-Hydraulic system with the radial piston type pump that varied volume based on demand...which was an industry leading advancement that held JD hydraulic systems in the industry lead for 20 plus years over their competition...1961

Direct injection diesel engine standard on their tractors...others had tried and decided to use other injection systems utilizing pre-combustion chambers. This began in 1949 on the R- diesel and continues to this day. It was one reason for their successes in claiming the top fuel efficiency records at Nebraska that held for over 30 years until not being beaten but by another JD product in the early 80's.

there are other things...just a sampling here.

Um, Im going to say the first with syncronized transmissions, first with the full powershift trans I believe, First with a great factory cab ( In my opinion)
