LS makes disc harrows and rotary tillers?

[BSHfieldmaster]

I just picked up an LS catalog of equipment available from the dealer that I am buying an XR4040 from, it has mowers, rear blades, tillers, discs, rakes and harrows in category l and ll, the back of the catalog says that they are from King Cutter and they are all labeled LS and painted LS blue.
