A G Gleaner was an enlarged CII and the F was a slightly shrunk CII. Due to several problems within the G, it was replaced with a much better M. The F stayed until the end of the conventionals. The G has more capacity than the F but also more weak points. The G replacement M is a much heavier built machine and lasted to the end of the conventionals too.

Do you know what were some of the weak points on the "G" and do you know of any updates or any good fixesIJ Is there a fix for the very weak cutter bar that has the two foot bar that attaches to the gearbox. Do the "G" have the heavy duty transmissionIJ If I'm correct weren't there 2 different trans. that were put in.

G had a lightweight header w_20" auger. l and M were first with 24" auger, strong header frame. Rockwell tranny in G -- l and M started w_Rockwell, changed to Gleaner design in 74. l is same walker width as G (53"). l was first production Gleaner with open concave (higher capacity, less grain damage),introduced in 72. M followed 1 walker narrower and 1 year later. E3, F and G were introduced in 68 at 32", 42.5" and 53" separator (walker) width. K with GM engine replaced Allis engined E3. Gleaner had 63.5" proto at same time but didn't make production (too big for the time). Many of the high capacity features (open concave for example) that were developed for the 635 were incorporated in the l.

The G's around here all had severe problems with shaft, crank and bearing failure on a regular basis. Dealer told me that the enlarged CII design didn't get any heavier cranks, shafts or bearings and were carrying more width and weight. The l_M cranks, shafts and bearings are noticably heavier_larger than the G. One neighbor broke 3 walker cranks and several bearings in 1 year under normal use and traded for a NH. He later returned to the Gleaners but has nothing good to say for the G series. We both had CII's and loved them, he went G, I went F.

Hey MHarryE, Do you know if the walker cranks out of a l will fit if a GIJ Couldn't they be just changed out. What year were the G's made betweenIJ Thanks for the info.

a g is a 6 row machine a f3 is a 4 row machine if you are looking for a older combine pick up a m or a l some of them are getting cheep the open concaves make a lot better grain quality and electric header control works a lot better not been around a g but owned a e3,k f and now a m2 and those two quality is what i really like
