When you push the hydraulic joystick forward past the first detent the stick will snap into (and stay) in the float position. The float position connects both cylinder ports to return allowing the cylinder (or snowblower in this case) to use it's own weight to follow the contours of the ground.:good2: The snowblower will go up and down on it's own as needed while staying in contact with the ground. Essentially the joystick has four positions going from back to front. Lift, neutral, lower, then float.
