The other day I had my 170 out just for a few minutes, heard something pop and had hydraulic fluid running under the right rear. Did t have time to dig into, just backed it back in the shed. So today I dove in, looks like the hydraulic hoses going from the spool valve to the break away couplers have been rubbing on the rock shaft for the past 5/ years. And also petrified.

The other side came off a little easier. Don’t see any cracks but might as well replace them while I’m at it.
