Yeah, that's the JD squeegee, and it works great on my asphalt and concrete. You don't have to pay the big JD $ for one, though. Go to Tractor Supply, or another Ag store and buy a rubber "Cow Mat." Cow mats are typically 4' x 6' and are 5/8" thick, or so. It will cost you $40 to $50 bucks for a cow mat and at least that much for the JD stock squeegee.
Unbolt your blade cutting edge, lay it on the cow mat, and mark the length and width adding about 1-2" to the width. You can cut the rubber with a utility knife and elbow grease, or use a linoleum blade. After you cut the squeege to size, lay the cutting edge back on the newly cut squeegee and mark the holes for the bolts. Drill the holes for the bolts. You will need longer bolts than stock to re-assemble the squeege, which is sandwiched between the cutting edge and the moldboard.
