With respect, and I do respect your judjment and ideas!!, A standard M pinion has a splined brake shaft running out the end into the brake housing. The differential drives the pinion gear directly. The M&W pinion is hollow, and driven from the outside. In the hollow center is a shaft that is driven by the differential, and extends through the pinion to the outside. The M&W clutch locks the pinion to this shaft, driving the pinion at 1:1 with the differential. The only thing the clutch does is allow the pinion to be disconnected from the differential. When the M&W clutch is disengaged the differential turns freely (spiders tumbling M&W shaft turning, and the disconnected pinion stopped) In my "Mind's eye" setup a set of gears would allow the pinion to turn much (or a little) slower. thus reducing the total gear ratio. It could also increase the ratio. It would be nice to use pre-engineered gears to make this "box" so ratios could be changed. The down side would be the wear on the differential, because it would be turning all the time (as though having a tire 70% smaller on one side. But for pulling, or creeping, I think it would be irrelevent). Jim

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
