I've always been taught to grease my rotary cutter u-joints every time I grease my tractor and other places on my cutter (about every couple of days of use). For this reason I have always removed the plastic guards from the shaft. It's just too much hassle to move this crap every time to grease the joints. I know, it's there for my safety but having run cutters for 60 years without getting tangled up in a rotating shaft I feel pretty confident that I can continue down that path if I choose to. All other safeguards are in place and operational.
That being said, I am now wondering if I have been foolish in greasing the joints as often as I have. In all the years of running a brush cutter I have only had to replace one U-joint. I think that's a direct result of my greasing schedule but mayhaps I have been overdoing it. I have a neighbor that never greases his and he has to change out his U-joints pretty regularly. He has replaced his entire shaft at least twice. I have NEVER had to do that.
Back to my question: How often do YOU grease your U-joints?
