Hi Rox, how goes it?
Well, you're the first systems analyst-turned-olive farmer I've talked to all day. /forums/images/graemlins/smile.gif Congratulations on your bold move, I think that's great.
One product that no one has mentioned, but that I find invaluable, is penetrating grease. It sprays on thin like a penetrant, seeps into tight places, then thickens up into a grease. Super stuff to have around.
Lots of other good ideas here too of course; taking all the linkages apart, cleaning them well with solvents and scrubbing, then either greasing them up or coating them with anti-seize compound, or, if you're operating in really dirty, dusty conditions, maybe using a "dry" type of lubricant like graphite powder, spray-on molybdenum disulfide, or the silicone spray (I guess maybe JD knows a little bit about tractors). /forums/images/graemlins/smile.gif
Bon chance, John
