| Would the header/ throat size match up on these? Or is it an L2 that matches up with a G? |

| The model "G" is all by itself for throat width. An L is wider and M is narrower. Some of the quick-tach low profile corn heads could be changed to go F and G and maybe even L and M. |

| Was a "G" capable of an 8 row corn head, or was it closer to an "M" machine? Perhaps in the right environment, an M would support an 8 row ?? |

| In corn harvesting, the cylinder width really has very little to do with the appetite of the combine. Cleaning shoe square inches, cleaning fan volume, elevator capacity and walker square inches are what determines how many BPA can be harvested. A 1978 and newer (forget the orphan 1977 model) F2/F3 combine has as many or more square inches of cleaning shoe and walkers as a G. Cleaning fan volume must be nearly double of a G. Elevator capacity should be just a tad better because of the speed it runs. A G was available with an 8-row 20 inch head when corn was only 100 bushels per acre. The model M series was more fan volume, more cleaning shoe and walkers and elevator compared to any G and was therefore a higher capacity combine in corn and was never offered with any 8-row corn head that I remember. The model L was available with 8-row 30 inch I think. |

Thanks Doc, I realize that the corn yields today can overwhelm the "Oldies but GOODIES" , it's been slow going with the F2  . BTW, how many walkers were in a G ?

| Five, but they are 18 inches shorter than a 78 or newer F2/F3. |

| many years ago the neighbor bought a "rebuilt" G Diesel/Hydro. It was a sweet machine. In dry corn with a 6 row head that thing would flat out eat corn. It was impressive for an older machine, but when the corn was heavy 20 percent or higher it slowed it down considerbly mainly because of what was mentioned about the separation area |
