Combines M2 size

[big_orange]

Cylinder width is 44-45",Width to outside of drive tires is 10-11',with 23.1 tires.

The M-2 has a seperator of 45" by 6" for 2 sq. ft. or area, compared to an l-2 which is 53" by 8" for a total of 3 sq. feet.

I'm quite sure the M's had a 40" cylinder. Seperator would of been a few inches wider. M's were the first of the open concaves and the previous G's (with the closed concave)had the 44" cylinder. Please correct me if I'm wrong. If anyone could possibly tell me why they named the next larger combine from a M an l please do. If you ask me the l (with 48" cylinder) should of been a N and the first rotarys should of been R's. Anyway Gleaner was so much on the right track with the conventionals, why didn't they just go wider with the down front cylinderIJIJIJIJIJIJ

Think shirt sizes Dan. M - medium l - large ;-) Ed in Montana

I had always wondered why they had labeled them like they did, but that one I had never thought of. good one... we sure are getting the rain today, havent planted any corn since last tuesday.

Alphabetical order. E3, F and G introduced together in 68 were larger with increasing letter. K with GM engine quickly replaced the E3 messing things up (skip H and I - those letters just didn't fit in). l was next model introduced in 72, followed by the M a year later. There was a narrower version in the works, but it was too expensive. Allis-Chalmers had started a numbering system for development models around 1970. N1 - 635, 63.5 inch wide separator, never made it N2 - Rotary, became the N6 N3 - l N4 - M N5 - narrower than M but l_M style, never made it N6 - G replacement, K and F sides, 53 inch separator, never made it When it came time to introduce the N6, the N was not supposed to be used, but Marketing liked it. They changed the whole nomenclature system. N5 - Class 5 N6 - Class 6 N7 - Class 7 And why no wider machine than the lIJ The N6 toasted the 635 so badly that all other large machine development stopped. Everything was focused on making the N6_N7 reliable, feed, and perform in tough crops like green stem soybeans.

Thanks for that. Your right in that the l came out first which points out my mistake above where I said the M's were the first of the open concave machines. That also helps explane the way they got lettered. I realize it doesn't always have to make sense. I wonder how the 635 would of did in the tough conditions especially if it had the down front cylinder! Seems like the tough conditions limited the sales on all rotarys and gave JD a big edge with what they had to offer, (keeping in mind many do not pay attention to crop loss as much as speed). I wish Gleaner would of advertized the channel helical kit they had in the early '80's as for tough conditions instead of just edible bean and green sunflower attachment. Thanks again.
