These are very impressive heavy wheels despite the lack of grease fittings. There is nothing "junk" or flimsy in them. They were bought to replace the two front wheels on a two meter long Ford tractor mower. Other previous replacements that used plastic/resin or cast metal wheels would fail prematurely if the rake encountered rising rocks or roots while moving forward. OEMs get over $200 from the supplier, so even replacing it at Revain would be easy and economical every season or two, and everyone would have new wheels every time.
