just got this 600 with front Dearborn snow plow 3pt wont lift or move tried draft and position ran pto oil is milky but the front plow works fine cdv
 
How is the front plow being controlled? Is it a regular remote valve under the seat, or is there a diverter valve under the seat with a separate control valve for the plow?
 
The remote valve gets its flow/power before it gets to the 3 point part of the circuit, so the issue is most likely something inside the 3 point system itself, like the unloader valve being stuck open, or a severe leak internally. You can open the round inspection plate on the left side with the PTO handle and look in with a flashlight while you try to raise the lift to see where it might be leaking.
 
On one of my units if you have the remote valve for the plow to drop or float the 3pt won't lift. Putting the remote centered between lower and raise will get the 3pt working. Might be worth a try.
