That's pretty much what I'm finding for other types of tractors, nothing on these. My guess is that it's an adjustment overlooked by the dealer before delivery. What you suggest is pretty much what I'm planing to do on this weekend.Certainly those bolts are intended to be stops. In absence of official directions for adjusting them, I would turn the steering gently to what looks sensible to you for "max left turn," back that bolt out to just touching & thus preventing further turning. Lock the lock nut. Repeat for the right side. At the extremes there should not be anything straining hard or binding and you should be enjoying the tightest turns feasible. Somewhere buried in a shop manual there is probably a specification on max turning angles, etc.
service manual for gc2400 does not even show them on axle/spindle disassembly.There is nothing in the owners manual about these bolts, what they are for or how they should be adjusted.
