I just bought a set of tracks and need some info. When installing a set of steel tracks (Loegering Trailblazers brand) on my 773 Bobcat (10x16.50 tires) do I need to install a set of wheel spacers? I noticed in the owners manual it gives instructions on how to install the spacers but doesn't comment if they are necessary. Could there be a problem with them rubbing the body of the machine. I don't want that because I just painted it last summer. Thanks!
