My dozer blade and swing function has completely stopped working on the kubota, all other functions working as they should. Have tried changing the relief valve (a3) and after that the functions came back, but when I stopped the machine and started up again the dozer and swing where not functioning again, so back to square one. What can it be, any ideas on how to troubleshot this further? I have access to pressure testning gauges if someone can just point me in the right direction. Attach hydraulic diagram for the KX61.
Might want to ask in the mini excavator forum.
