Hagen Brothers farms,Goodrich ND | I looked at a tube of the SD poly urea grease that worked so well for me, it's green. I understand about the steel wear ring, in the off season any moisture /dirt will form corrosion on the ring that grinds up the seal when you put it back in service. the poly urea grease may better coat the wear ring the way it creeps and lessen off season corrosion. Odd they would use steel when many JD wheel bearings with that multi lip seal use a plastic wear ring ???
Also the dust issue, my drills only plant soil that has not seem a tillage tool in over a dozen years, and it is damp spring seeding. I never have a dust layer on the drill box lids. comparing that to seeding dry tilled soil would have to make a huge difference. |
