I-6 4th and 5th slider won't work for 5th speed on a M input shaft. M locks onto 20 teeth and the I-6 locks onto 23 teeth. If you use the I-6 transmission input shaft it uses a different constant mesh gear than a M. That speeds all gears up along with the PTO speed. Sixes use a ring and pinion that gives faster ground speeds in a M. But if you need a standard low gear ground speed you won't have it. Try a 9 speed transmission. They speed the PTO also in high range.

For a ground driven rake no problem.
