some answers to combine quiz

1. What company was the first to introduce electrohydraulics in combines? Gleaner was first in 1972 with the M & L.

2. Who was first with hydrostatic drive? Gleaner was not first but started producing Hydro drives in 1968 for the F & G.

3. Variable control ground speed? From what I can tell Gleaner offered a variable speed in 1951 with the A. Hydraulically controled from the operators platform.

4. Auger-type header? Gleaner was first in 1923.

5. Variable control for cylinder speed? Allis-Chalmers model "All-Crop" in 1935. By variable I mean being able to change speed with out adding or removing spacers in the pulley.

6. Stone protection? By at least 1961 Gleaner offered as standard equipment the stone door on the E.

7. Yield monitor? I found a brochure offering a yeild monitor on the K dated 1974. The larger L & M might have had it with their 1972 intro.

8. Shaft monitors? The earliest for Gleaner that I found was 1972 L.

9. Rasp bars in lue of spike tooth cylinders? Gleaner was first in N. America in 1923.

10. 12 row corn head? (who was first with 6 & 8 row also?) Gleaner again in 1979 with the 12 row and N6. It appears the C Gleaner had a 6 row available in 1961 or 62(not positive), and the CII offered an 8 row in 1965 or 66.

Some other info:
Allis-Chalmers introduced Rub-bar cylinder bars in 1935 on the All-Crop. This made it capable of harvesting more than 100 different crops. Also flax rollers helped reach that 100 crop capability and kept stones from entering the cylinder area.

The All-Crop is widely thought of as the successor to the binder and thresher as the first combine to be sold in great numbers.

By at least 1961 quick attach heads were offer by Gleaner though not as handy as todays quick attach it turned an all day effort into about a 30 minute job.

I'll do some more research on torque sensing drives and variable speed corn heads and other innovations. I believe Gleaner will also be at or near the forefront of these innovations judging by the history I have found.

PS With the abundance of Gleaner info I have found I probably will give my speech for Ag class focusing on Gleaner. Thanks for the info and any additional info you may add to this project.

On question 2: This book states that IH had the first pioneered hydrostat drives in 1964.

I'll find some more later....
Other combine trivia...

JD claimed to be first in "successfully" marketing a combine corn head in 1954 first tested in 1953 marketed along with a "cornbelt combine" model 45.

Who had the first "patented" quick tach header system ??? John Deere had a 1965 patent or their "Quik-Tatch" header mounting system.

Who had the first electric header lift? Not electro/hydraulic, just electric. MH - MF ??

Grain Harvesters book shows AC's earliest corn head "attachment" was in 1957 on a AC all crop 60 and 1957 model A Gleaner and development was not begun until 1955 at La Porte. Gleaner Baldwin did have some type of corn harvesting combine way back before then but was not an "attachment" combine header but a harvesting machine just for corn with a sickle type cutter and large reels to push the whole corn plant in. The snapping roll type headers came later.

JD patented a "Quik Tach" system in 64 according to the GH book and it was licensed to other manufacturers also in North American and around the world after 65. No mention of "quick" attach headers in the Gleaner Baldwin chapter of the GH book.
