I'm lookin into a 54" power plow blade for my tractor and found a very lightly used one at the dealer off an x720 trade in. The salesman claims it was pulled right off the trade and its ready to put on my x758, but the closer I looked, I noticed it seems the hydraulic lines were about a foot and a half short. Also, I believe I need the valve to divert my hydraulics from the deck raise to the raise or angle cylinders even if the deck is off, correct? The salesman described it as a small cartridge that goes in the main valve block with a thumb wheel to turn it in and out, does that sound right? Any idea on price? He said the blade with hitch and all is $750, which is reasonable considering a new one is like $1600. But then he implied the longer hoses and the cartridge would be extra. Luckily I only live 1/2 mile from the dealer, so I'm going to drive the tractor down Saturday and test fit the plow, just wanted to get some input before I go. Thanks guys.
