I do not think this plow, which I have had for a year, has ever been greased. The two zerks are totally clogged. I have not decided if it is worthwhile for me to replace the zerks with new ones, even though the Ford recommended lube interval is every four hours. I only plow, on average, 5 acres per year, for food plots and in other areas for fire protection. My soil is sand.
I am 67 years old and have some inflammation in both elbow and shoulder, so fitting all those heavy, close fitting, pinned, parts back together will be a heavy task. I do have PLENTY OF TIME.
