Hagen Brothers farms,Goodrich ND | For what it is worth, My old drills had the type 1 and type 2 wheels like Jim describes below. I found I could greatly increase the life of the type 1 ( bolt through the wheel with a HD sealed bearing on the exposed side) closer wheel. I found that removing the two flat washers next to the wheel and replace them with an IH disc drill, opener disc seal assy (metal spacer with rubber washer) . Adding this IH drill disc seal in effect double sealed the bearing against dirt /water and increased bearing life several times over the stock setup. Those IH seals are cheap and easy to install.
For the type 2 wheels with the extra 3-4 lip seal, I found that packing the grooves in the seal with JD poly urea grease and making sure the seal and wear ring were smooth and clean with a coating of Poly urea grease made them last several years.
I now have aftermarket spiked closing wheels with a single large ball bearing in each wheel. I was a bit suspicious of a single bearing running with a side load, but have had no failures in 5 ? years, and they do an excellent closing job in wet, long term, no till soil.. |
