Guys, I have a question. Not to experienced on tractor Hydraulics, so I am asking the more experienced. I had a couple of hoses get cut when a plowing snow and my hydraulic blade's left/right angle mechanisms (valves and release valves) lost a lot of fluid before I figured there was a problem, to the point where, when not hooked up to the tractor I can move the blade left and right with ease - never tried that before so I was kinda surprised I could do that. I think i will need to hook up the tractor and get the fluid back in and then top off the tractor, is that all I have to do or am i missing something?
