    How much torque is needed to pull 75 lbs
    So I'm trying to make a go kart out of a push mower engine. I weigh 75 lbs, I'm crazy light if you were wondering how I'm so not heavy. Whatever. Anyway, the kart will weigh around 15 lbs, maybe. I am wondering if its possible. The mower has 4.5 horsepower.

    Torque is dependent on the radius of the gears you will use. Check this link, it uses a gocart.
