The company i work for has a kobelco 220 mk3. Every winter the left track quits walking forward it will go backwards and the other track works just fine. When the weather warms back up it starts working again. What would cause this i know a little bit about heavy equipment but this is above me. Thanks nate
Reverse the pilot lines and see if problem goes to reverse if so you have a restriction in the forward pilot circuit
I will have to try and remeber that. It started working again wendsday
