I am a terrible overgreaser. I believe that it is better to overgrease these open style bushings than to undergrease. I actually pump grease until I see it leave the bushing after about 5 pumps. Many pros only pump until they hear the crackle, you'll know the crackle when you hear it after about 3 pumps.
The closed bearings and bushings which have a rubber boot or seal need to be greased much more carefully. Too much grease there will blow the seal and that's no good.
Too much grease on the loader bushings makes a mess, I can handle that, too little and you wear the joint, not so good. I also grease at day's end so that the bare metal is not damaged by rain water. Also the used grease seems more likely to cake up than fresh grease.
