I personally checked this one out. It is as heavy and durable as it looks. I have one reservation, and that is, the one that I looked at closely did not have a turning main shaft, which means it does not have main shaft bearings. The cultipacker wheels turn on the fixed main shaft without lubrication. Don't have any idea how long the shaft or inner diameter of the wheel will last. Don't think about putting grease on the main shaft for a substitute, the dirt will mix with the grease and become a grinding medium. It would work better dry, for the sand particles would work their way out to the edge of the hub eventually. Old time farm implements (disks, cultipackers and other rotary tools) used wooden bearings and lasted for many years, providing the farmer didn't apply grease.
Keep the fun in hunting!
