The hydraulic control valves for the front loader on our 1967 International 2504 Industrial Tractor is leaking from the font. Hydraulic fluid is dripping from where the control levers connect to the valves and is leaking all over the brake pedals making them very slippery. This most likely means the o-rings have gone bad which happens when they are old and getting stiff. So, we'll need to take it all apart to remove the bad o-rings and install some new ones. Hopefully that will stop that pesky leak for good.
