I like the idea of the adjuster from the front wheels of an old mower, but replace the wheels with pieces of round 1/4" plate. Make them large so they don't get stuck between rocks. Alternatively, make new skids. Use a good hard steel for the bottom and they'll last almost forever. Instead of slots for adjustment, drill holes at the two heights. Since you won't have to tighten them down to stop from sliding in the slots, you can use wingnuts and hand tighten them for a tool-less change. Use lockwashers so they don't vibrate off.
