My friend and i are planning on building a racing lawn tracter. so far we know that were going to have to mess with the pullys, steering, and weld the front axle. by changing the pullies is there going to be more strain on the brake/clutch? also should i do anything with the transaxle like replace it with a motorcycle trans and a gocart axle. any ideas would be very helpful. Is the frame going to be strong enough or does that need to be modified too?
