Just order a bolt-on hitch or fabricate one. You shouldn't need front weights for those implements. I had an Exmark and now a Bob-Cat zero turn, not Scag, but same deal with them. Just stay within the weight recommendations so you don't overheat the transmission. Mostly a concern with the aerator depending on how much weight you have on it. Dump bucket, I don't know about that but the others should be fine.
