I hear you on that one , Bobcat in their great wisdom made the bushing that drives into the chromed rod end with a grease journal machined in the OD of the bushing , and then when they install the bushing they don't line up the journal holes of the bushing with the grease zerk , from not greasing the machine frequently enough the grease gets hard in that grease jounal "track" and /or it gets mixed with dirt if the pin and bushing is a loose fit ------------the easiest way I have found to clear such a clogg is to remove the pin and use a tourch to heat the bushing right in the middle all the way around , it don't have to be cherry red just enough to make it start to smoke and you may see grease start to worm out the holes , " TAKE THE GREASE FITTING OUT BEFORE DOING THIS " < as the little ball in the end will shoot out like a shotgun when heated , if you don't have an acctylene torch then a MAPP gas torch like the plumbers use will surfice , once hot put the grease fitting back in and pump it with a good quailty grease gun that will produce 10,000 psi and not one of the Auto Zone $9.99 specials , if it don't clear out then do it again with a little more heat ----------------- grease the machine every 8 hours of use with quaility grease and this won't happen
