Re: JD 4 Way 54" Blade
Frank, A 318 is an H2 system...meaning 2 separate hydraulic system, kinda. Your inner lever controls your front right (as siting on the tractor) outlets and your outer lever controls the front left outlets and the deck plus the 3-pt. A lockout valve on the cylinder for raising & lowering deck & 3-pt (located on the back left side of the tractor looking at it from the rear) will prevent movement of the deck & 3-pt when the outer lever is moved, like if you've got a blade on the front and want to angle it.
As far as the deck & the back blade lowering at the same time, they're moved by the same cylinder. You need to remove the deck when using the back blade or the blade when using the deck.
As far as kitchen table or 2 tractors, don't let wifey read this post and just say it can't be done and you just gotta have 2 tractors! Bob
