Rachet jack -- 40 hour intervals
Grease zerks
Electrode coulters
Pivot -- In all but the most extremely rocky conditions, the coulter electrodes should
not flex in the field, thus minimal movement will be realized at the pivot.
80-hour intervals should be sufficient.
Grease zerk
Hubs -- Use good quality wheel bearing or lithium grease for lubrication, but we
suggest that you grease the hubs sparingly. Over-lubricating the hub
will result in pre-mature seal failure, and an excessive amount of grease
in the hub cap/commutator. On an interval of 150 hours, 1-2 strokes of
grease should be sufficient.
