Just ran into an isssue with my 455 AWS while swapping out my snow blade for the mower (spring is coming). Removed the blade, which was working fine, and mounted the mower deck. To my surprise whenever I use hydraulic levers (raise/lower deck) hyd fluid squirts out the aux valves and the deck will not raise. It does have a lockout valve on it and I have it open (quarter turn, handle inline with hyd line). What am I missing here? Seems to have all pressure diverted to the SCV's and not the lift cylinder. Those SCV's should not be squirting fluid, they should be shut. Any ideas of where to look?
I guess I can mow just cant lift the deck.
