Nebraska, The land of corn and cattle | Yep, screw using oil, just put the grease in it and be done with it. Our Reinke dealer has the whole setup on a little trailer that you can come get and they charge X number of dollars per tower, or they will come do it as well. Just put the grease in, check it after the first year, and drain the water out occasionally and forget about it until the box goes bad.
Back when we used to use oil we just put 80/90 in them |
