Howdy folks, Just bought an old MM, mainly for the loader that came with it.I"m wondering if it has a high low range. Previous owner knows about as much as me, which ain"t much. Left of the shifter is a short lever, is that the PTO engage? Right of the shifter is a small housing that looks like a shaft has been there once and has been ground flat now. Wonder what that was? Brakes,throttle and clutch I have figured out. Reason I ask is because this thing goes like stink and maybe its due to the inline 6 in her but it would be nice to take her down a notch.
