IH and some aftermarket had some faster 4th gears, but hard to find now. Some of the 6 series had a 4th with gears one tooth bigger driving a one tooth smaller 4th and 5th slider compared to the M. Problem is the transmission has 3 gear sets that are one piece with a different size gear on each end. So sometimes when changing one top and bottom set of gears it gets more involved. Since all SM gears except first is a different ratio and the counter shaft is a different diameter where the gears go. When installing in a M you need all the SM gears, counter shaft and the reverse idler gear. Aftermarket 9 speed may be a option, but they also speed up the pto. So if needing the pto and running the tractor at a higher speed you need to be pulling a light enough load to run at less engine RPM. Also some gear boxes are around that go where the belt pulley gear box is to give another speed between 4th and 5th. Not very common. If you never need a slow first a W6 ring and pinion gear can be used to speed all gears up.

IH put a high speed 4th in at the factory in H's, at least, the serial number tag would be an X1F, F, as in Faster 4th. I Have an H that my dad ordered that way.I love it.

Interesting. That would make 5th gear faster also? Wow Kent
