I have a max 2 with 14 hp briggs. I am very new to the 6 x 6 world, so this may be a easy question. It seems that my driver clutch is stuck open, or i think it is open. The belt is laying down at the bottom of the shaft. When the engine is throttled up should i be able to see the clutch close up and the belt ride to the top? If so, what should I try to do to free it up?
