Intelligent Hydraulic Control Holds ISO 4406 18/16/13
Closed-center load-sensing pumps meter oil to the lift arms and auxiliary circuit so a skid steer loader can run a cold planer without starving the drive motors. Factory flush logs ship with every machine, and dealers sample fluid at 250-hour intervals to keep particle counts inside ISO 4406 18/16/13 before valve spools stick on dusty landscaping sites.
