Ok heres the scoop. I'm going on saturday to look at a used 255sx vib plow. The machine is @8 years old. The current owner bought it and used it mainely as a back up machine ( he does mostely large stuff) He hasnt used it in 3years and figured out that he has no use for it now. He said that everything works great except that the 4 way spool valve for the up and down on the plow is frozen. He wants $1500 for it.. A new valve coplete with linkage is 789.00 but many rebuild parts are available. so what do you guys think? what should I look for as potential problems? Any thoughts on the valve? He seems very open abouit the condition of the machine. but it remains to be seen.
