Fluid lines bent; opinions please

[cdover73]

The other day I was moving some dirt around my pond with my 4530 and box blade when the scarifirers caught the root of a small tree (about 6" x 30') and caused it to uproot. When I tried to back off the tree, the root and stump was tall enough to hang up under my tractor. I called myself looking as I was backing up, but the roots caught and bent the toolbox mounted on the side as well as the power steering lines just above it. The lines are not broken, but the bracket that holds them is bent and one of the lines is bent slightly. This isn't enough to really worry about, but I can't leave it like that. What I am wondering is would it be okay to change out the hard lines to the power steering with hydraulic hose so I can tuck them closer to the frame instead of them being stuck out in the open. I know I would have to use the same i.d. to keep the flow rate the same. Also, has anyone attempted to fab a set of skid plates to protect the underside? Pics?
