The rover rancher auto-drive is the closest I’ve seen to yours Gizmo,
https://www.outdoorking-forum.com.au/forum/ubbthreads.php/topics/102899/rover-rancher-auto-drive-help.html is where I found some clues and the rancher auto-drive manual for service instructions.
My only problem now is I’m looking for some info on setup. I’ve changed the corks, got the clutch plates machined flat and true again, changed the drive belt and rebuilt everything. I get forward and reverse on concrete but reverse seems to slip a bit so the clutch isn’t engaging fully, so mine just needs adjusting. If there’s anyone out there that can help with setup of a Rover Rancher Auto-drive 28166 I’m interested please!
