going back and reading my response, I realize that I sound much like a jerk. of course there is no way for anyone here to know whether or not I'm qualified to handle this project. just for giggles, allow me to put it to rest.....I am, lol.

grease, that is a pretty nice ride you've got there. i'm a junk-a-holic myself. to tell the truth, i'd rather have a pile of scrap iron and my tools as to have a blank check in an industrial supply store. i can see you've made use of nearly the entire mower while working it into a cart frame. nice job, man. I'd actually like to see what the driveline looks like from underneath if you ever get the chance.

so, back to my original question:
5 hp briggs, 702 peerless, access to differentials if i choose to use them....any ideas on pulley sizes on engine and tranny?

currently, my plan is to run a belt from engine to tranny, then from tranny output straight to drive wheel. with the creative use of some u-joints, I'm planning independent rear suspension, so at this point i'm just using the differentials for decoration in my garage.

I won't bother you folks after this, but I will give you a couple of tid-bits on my way out.

1. Thanks for the link Squidd. I'll give that a look and hopefully get some help there.

2. Your idea of "homemade" and mine are probably totally different, tgames. Being as I work in the design aspect of one of the largest manufacturers of flat-bed and drop-deck trailers in the world, I believe I am qualified to design/build a safe go cart capable of carrying a 55 LB child.

3. He was never meant to go 20-30 mph. I had intentions of making use of sliding seat rails which would allow me to drive this machine as well. For his time behind the wheel, a simple "stop" on a hinge will be latched into place that will govern how far he can push the gas pedal, thus not allowing him to turn as many rpm which will limit his speed and his potential for climbing beyond his experience.

Just an FYI.....for those of you who think a cart or even a mower for that matter is better just because you bought it...consider it was MOST LIKELY built using this thought process: "As safe as cost allows"
