The casting that attaches to the tractor to feed the hydraulic lines has one round hole and 2 slotted holes. It also has a plate machined with the same hole pattern with O rings for seals. No mater what I do I have a small leak in this area which makes the floor board slippery. Any suggestions????? <!-- s:( --><img src="{SMILIES_PATH}/icon_sad.gif" alt=":(" title="Sad" /><!-- s:( -->
