Gleaner G vs L

L had more cleaning capasity; for sure.   I've ran them both.

G could thresh it but struggled to collect it they say.My A2 was a narrow version of a G.Never had any complaints on collecting grian it threshed.

For threshing and separator/cleaning capacity, the Models E-E3-K are the same and 3 walkers wide.   The model F and short F2 are 4 walkers wide.....the model G is 5 walkers wide. The model M actually replaced the model G, but was in reality bigger in all respects. An F-3 or late F-2 with wide tooth cylinder bars will make a G look pretty stupid in corn and soybeans.

A and C and G were similar in mainshaft designs, but you can remove a walker from a G and install it in a K or F. The A and C walkers were an inch or two wider.

Lots of guys claim lots of things. My Uncle Bob had a G and it was a great combine for him.

Which L? Difference between first and last models fairly significant. Trev.

Doc....the reason for mentioning the 7700 deere combine, was the square inch cleaning capacity was larger on the "G"s than the early 7700 combines, you will find the comparison on file in the charts of that era.

i'm not sure what year 7700's, but a dealer told me this, and I didn't believe it until I saw it personally in print of the camparisons of brands of combines! not that it really makes much difference now, nor did it to me back then! just a tid bit of info from that era.  

Creston, the L was 48 inch, the G was 44. way more cleaning capacity, and most importantly, the open grate concave and front raddle, so the L was supposed to be much bigger.

The F and G were the same family, F was a narrow G with quite a few powertrain differences.

The A and C and A2 and C2 has the same relationship the F and G had, the G replaced the C2, F replaced A2.

The G was slightly challenged on airflow in the cleaning system. If you new how to set it, it was not an issue. I guess it has a pretty even airflow pattern at slower speeds, in talking to a guy, he said there is a grass seed company down there somewhere in OK that has 3 G diesel hydros that they do all their grass seed harvest with.

Dad allways did pinto beans with them and they did well. the F would usually outclean it though.

They were the first series of combine available with a hydro, IIRC first offered in 69 (G launched in 68) and the hydro setup had a simple mainshaft that would never have issues, unlike the gear drive with tapered splines which loved coming loose and taking a dump, so essentially the worst part about a G was not even present on a G hydro.

Little known fact, the black frame cornheaders widest width is to match the G, even though the G had been out of production for 5 years before the first black header was sold. 
During production, the biggest cornheaders offered were the 6R30 and 8R20. They get a little light with those and had frame weights available, as well as the "fat back" full cast rim and hub unitized assembly.
