You must see something other than what I see, because it looks like 4 NOS Lawnboy wheels to me.Uh, Are you sure that's the image you were intending to post? Looks like an Exmark ad to me.
View attachment 32802 This is what I see. :confused2:
Edit: Oops, sorry about the tiny image. If you click it, it will open big.

Any time I run across some good used ones, I hoard them in my stash of parts. They may not be new, but when I drill them out and slide a bronze bushing in them, they roll good as new.
New ones are getting harder to find so buy them if you see them.
Where do you find the bronze bushings? I'm thinking of doing that.
Thanks
