What would cause splitting on the female end of the quick coupler?
This is twice with the same skidsteer "tree puller" implement. This is the low-flow hydraulic fitting on my Kubota SLV75. The first time it happened I was worried about it being a banged up male end (bought the tree puller used), so I replaced that too.
The device is nothing more than a single piston for moving one arm of the scissors.
I'm hoping that the answer is "pulling too hard on the line" because then I can just get a longer hose or be more careful. I'm not sure what else it could be.
I'm interested in an expert's opinion.
