Steering
 

Based on comments, at first glance the steering is not always obvious. A tractor steering wheel is mounted vertically next to the front left seat. The steering wheel is attached to trimmed front bicycle forks. Rear sprockets welded to the forks link by chain to a bicycle crank. One pedal from the crank is used as a pitman arm and connects by a steering rod to the left golf cart spindle. The first design tensioner used for the steering chain was a rear derailer, which worked well when turning right... but not left! A second crank set was eventually used to tighten the chain. Spindles link to each other by a front mounted tie rod. Similar in design again, to a model "A" or hot-rod.
 
Getting the correct ackerman angle took some trial and error. The ackerman angle is the angle that the spindle arms, that are connected by the tie rod, make to the front axle. This angle controls the amount each tire turns in relation to each other during a turn. On a four wheel vehicle the inside front tire needs to turn more sharply than the outside tire. The angles are supposed to, for a front mounted tie rod, meet at the centerline in front of the front axle at a distance equal to the distance between the front and rear axles. Some inaccurate measuring required a few tacked on additions to the spindle arms to get everything to align at least close to correct.
