so many people have talked about puting a trans infront of another one but has anyone ever got a peerless 700 or somthing like that and got a 7 speed mountain bike gear on the end of the trans and another mountain bike gear on the axle you are useing, if the 700 has 3 gears and two 7 speed gears you would have like 17 gears (has anyone done this if not i will be doing it to my craftsman ) this one, thanks

I can absolutely with out a doubt guarantee you that any and or all mountain bike sprockets are not designed to be used on a lawn mower. They are designed to be light weight and withstand normal human use as soon as you start adding the superhuman power factor of even a 10hp it'll just rip itself apart you should try building a stepped sprocket pack like those and just use regular sprockets but I dunno if that'd work or not. Or you could slam a torque converter to a 6 speed high low like I use for pulling.

Like moose said. They can't stand really heavy use. Heck I just snapped the one off my mountain bike after I rode it up a really steep hill. LOL Yeah if anything I would use an MTD vari-drive to a 700. With that you could have a load of good gear ratios.

My bike gears do fine with a 50cc engine strapped to the bike, Like you said tho I dont know how they would work with 10HP

I can't see it working out well. Not only are bicycle gears unlikely to tolerate the torque of such an engine, let's not forget that by putting the bike gears downstream of the 700. So now, you're multiplying the incoming torque by a factor of as little as 2, or as high as 9, depending on the particular gearset of your 700, and what gear you're shifted into.

To put this into perspective:

Your 15hp engine likely has a peak torque of about 25lbs/ft at 2500RPM. Assuming a 1:1 pulley ratio going into the 700, that's fine. Now- run that thru a 9:1 first gear in the 700, and you are now sending 225lbs/ft into the input side of those bike gears. Imagine what the output side is seeing.

Ive stripped gears on my bike; it wont work.

You could build a sprocket pack, but you will also have to build a derailleur as well to move the chain to the gears.

And you will need to figure out some sort of clutch system.
