Machine down
Skid steer and attachment circuits: the couplers are the weak point
A skid steer changes attachments several times a day, and every change is a chance to connect a dirty coupler. On these machines the failure is more often contamination than a burst hose.

What splits a female coupler half
A cracked female coupler body is not a manufacturing defect and it is not bad luck. It is almost always one of three things, and two of them are avoidable for nothing.

Mini excavator hose and coupler maintenance: the items nobody schedules
Service schedules cover oil, filters and greasing. They rarely mention the hoses, which is why a machine on a perfect service record still strands a crew on a Thursday.
