This may be a dumb response because I'm not familiar with the tractor, but....doesn't that drive from the flywheel side? If so, it wouldn't make any difference. If you can drive it from the output side, it would reduce speed and maybe increase the torque some. It would be capable of pulling more because of the extra reduction. The reduction output doesn't come out the same spot as the normal crank so the mounting would have to change some too.

If you have a good running engine in a B10, don't try to change that. The way to reduce speed and increase torque is with a reducer pulley set on the bevel gear box(BGB) and the transaxle. The reducer set (or two speed set) was available on later models but I'm not sure for the B10(I have three B10 series but none have the two speed pulley set). Check out our manuals for what you want. The easiest option would be to find a smaller pulley for the BGB or a bigger pulley for the transaxle. Good Luck, Rick
BTW the only dumb questions are the ones that aren't asked.

So, let's change this to : if I was building a homemade garden tractor, what would using a gear reduction motor do :
- would it just slow down the tractor ...( this thing is slow as crap)
- would it increase torque in direct correlation to the respective gear ratio....( this thing is a pulling monster)
- would it both increase torque + slow down the tractor ( this thing is a pulling monster...but wow I can walk backwards faster)
- or make little change ( or this did little but it's different)
Ultimately I'm just looking for something different that at a show people would think is cool.

- IT would slow it down. Most gear reducers are about 6 to 1 so the speed would be 1/6th with the reducer.
The top speed in 3rd gear should be about 5 mph. If you want speed, put a bigger pulley on the BGB or a smaller pulley on the transaxle. I hope that this answers your questions. The B10 is a great tractor. Good Luck, Rick

Speed of the gear reduction drive would be the engine speed divided by the gear reduction ratio. If engine speed is 3600 rpm and the gear ratio of the reduction drive is 6:1, then the gear reduction output would spin at 3600/6=600 rpm.
At the same time, the torque of the gear reduction output shaft would be 6 times the torque of the crankshaft of an engine without the gear reduction.
This ignores some gear windage losses of having the gear reduction gearbox (basically there are friction losses with the gear reduction gears and bearings -- minimal.
