I"m new to sickle mowers so please bear with me. I got my J.D No. 5 sickle mower operational. I mowed a little and noticed smoke coming from around the metal on the end of the pittman that connects to the place on the machine that causes the whole thing to move back and forth. I didn"t know what else to do but shut it off. Upon inspection (after it cooled), there is a little play on that end of the pittman connection. I had this part greased and it appears to me that there really needs to be a bearing because of the number of turns this part makes and the speed which it makes them but it"s clear that it was not designed for one and there is not room for one. Should I just continue to grease (how often) and press on or is there something else that I need to do. I sure didn"t like the looks of it smoking and how hot it appeared to be. I have no idea what is "normal" on these things since this is the first one I"ve been around. Any help/suggestions would be appreciated. I know there are lots of seasoned users on here so I thought I"d see what the experts had to say. Thanks Before it started smoking, it sure cut like a dream though. I was impressed.
