I am trying to find info on the eagle hitch on this tractor. I have a strange bump rise going on whenever I lift the brush hog it will continue until it blows out the return line flooding the trans tunnel with hy-trans? I can not seem to find any info on how to remove the piston to replace the seal? Searched on line and I have three manuals ~ Op. manual,I&T shop & service and Case shop manual C-202 from I&T none of these cover the eagle hitch disassembly or re-assembly? Not a single video on youtube either. If it had the end with the bolts like the 430 I would have it done already!! Very frustrating!!
