1998 D5C Hystat-- Was running the dozer and caught the edge of tree with the bottom edge of the blade, which slowed the dozer momentarily, and burst one of the supply hoses to the opposite side cylinder that angles the 6 way--- would this happen even with a hose in good condition? or is it more likely that the hose was just old ? ( original 1998 hose) - just wondering if this type of problem occurs regularly- still fairly new to running a dozer.
