Understood. I was speaking in general terms. The OP I think has MTD but some with other brands have joined in.Not all splitters have ejector arms...
Another thought I had was to split a heavywall pipe in two lengthwise, line it with rubber to be kind to the ram, piano hinge one side and pin the other. It doesn't have to be pipe... could be two sections of angle iron. Just need to be sure the face of the cylinder that holds the seal can take the abuse.
