I'm looking at a GEHL compact telehandler. The joystick movement left/right doesn't operate the bucket curl, it operates the telescopic boom. The bucket curl is controlled by a thumb control on the joystick. Is this common in the construction industry? Every tractor in the world has the bucket curl controlled by left right lever motion. It actually is really easy to control, the problem is I'm so used to the tractor style I think I'd constantly be doing the wrong motion. Any idea why they might do this?
