i know this topic is done to death but i had another idea for a motor linkage. you put a hydraulic pump on the vert engine, run a line to a hydraulic motor geared to the motor. when you hit the lever, the motor goes and so do you! the motor would be slow, but since it is powerfull, you can use aggressive ratios to up the speed

Hydraulics are actually a good idea. You could put the hydraulic motor anywhere you want, limited only by the pipes. Good hydraulics are actually very efficient, approaching the efficiency of belts. But those are expensive. Most surplus hydraulics are simply "OK". Since hydraulic motors make great torque, you could probably just directly drive the wheel and get decent speed as well as accelleration.
As for the other question, yes, you could in theory connect the wheel directly to the engine. The problem is that with a 1:1 ratio, you would need massive amounts of torque to move the wheel. If you are going to do this, electric is your ownly choice.

well we need more info on the battries. look on the label. tell us voltage, how many you have, amp/hour number
hydraulics would be really cool. have a huge grabber arm come out from the back of your cart to tear other peoples carts to shreds hehehe

the battries will at most give you 24 volts dc. your motor most likely needs 120 volts ac. are the battries big? i would use the motor off the electric lawnmower. if you still want to use the washer motor, ether get a loooooooong extension cord, or an inverter like the one on aaron's circuts page.

ohhhh
those are engine start battries. they turn over the engines on riding lawnmowers. they are only good for high amperages for a short period of time. it would be impractical to use theese. i would use gell cell, get like 20 amp/hour units, at 12 volts you ll need ten and the motor should work. that is why i suggested the motor form a battrie powered lawnmower. powerfull and low voltage. if you do use one of theese, get a deep cycle marine battrie at the least, gel cell is the way to go.

Umm, no. If you look at gocartmaniacs most, it says they are for an ELECTRIC mower. They are not start batteries for a gas engine.

mmmmm. diesel, one of the greatest overlooked inventions of the industrial revolution.
i'm quite sure that the battries are engine start. do they have an amp/hour rating, or jst cranking amps? trust me, deep cycle battries that big wont sell for 10$ where is the site you got your information? i would suggest you get a big 12v motor, and a deep cycle marine battery. there are actually some sites (of witch i forgot) that shows you how to modify engine starters for high torque motors.

I have been using an electric lawnmower for 17 years. Clean, efficient, quiet and zero maintenance...Compared to the gas mower that my (me and my brother) lawn business used to use, it was a dream. You could actually smell freshly cut grass, and not gas...
Anyway...

The short answer is no. The motor is completely wrong. You need a motor designed for 12 or 24V. eBay has TONNES of them listed. You then need a way to control that motor. Check out the two electric scooter topics:

yeah...I just think it would be a pain to have to charge it...especially out here I could probly only mow 1/3 of the "Lawn" and then have to charge it. Im waiting for fuel cells to get cheap

i enjoy the smell of freshly cut grass accented by the fragrence of burnt gasoline. it makes everything more better better more...
i am quite sure wal mart doesn't carry those king of battries for that low of a price. buy one and try. if it doesn't work, you only be out 20$
