Rich, I had in mind about what you suggested but was overcome by a brief random heavy duty gust of lazy and other extenuating corcumstances. (See post to Bird). I had the trippple valve kit with TnT installed when I bought this beast. One goes to extra aux outlets in back for hydraulic scarifiers, cement mixer, etc. The three valves are mounted as one and in a hard to get to position. One of the hoses to the rear aux quick connects had to be replaced with one bent more sharply for clearance as it hit the cab while trying to plug something in and it couldn't be used without partial dissasembly and a helper. Not convenient. I basically don't like to accept coincidence as the reason for much of anything. I figure the odds are in favor of that changed hose going to that valve as being the culprit as that is the only thing on that trippple valve assy that was changed at the 50 hr.
One day I am going to have to pour a set of ramps with safety curbs to drive the tractor onto for easy access to the underside. Anybody out there done this, seen this, know of any reason it souldn't be done? Speak now or forever hold your peace. I might come up with something that would work safely and conveniently for other vehicles as well. Don't want a "Grease pit", would likely fill with water, dirt, debris, distracted people, whatever.
