I don't grease my hoe as often as I should and no way would I ever do it daily. In the past it would begin to squeak or squawk before I would get around to it. November of last year I ordered a case of Amalie Pro Tac+ with 5% Moly. This stuff is far better than the off the shelf moly grease I was using. It seems to remain in place and protect better. I have only greased the machine 3 or 4 times since getting it and have never heard a squeak. It seems like most of the fittings take less pumping before it emerges around the pivots or joints but I still go through a couple of tubes each time.
I've had one fitting that would never take grease and it really worried me because it was the bottom swing pivot for the boom. I would always try and would end up prying the coupling off because it would become stuck from the back pressure. I kept thinking I would buy or build one of those things to hammer some penetrating fluid into it and try to get it open but never did. Today when I got to that fitting I had just changed the grease tube. I hooked the coupling on and pulled the trigger. The DeWalt pumped up then grunted, pushed a little grease out of the relief then then started pumping normal. Low and behold the pivot started taking grease which is a huge relief.
I still have a ball joint fitting that won't take grease so the penetrant pounder may yet be in my future. I have removed the fitting and made sure it was open which they always are. The problem is a deeper restriction.
