Welcome snowboss! Congrads on the sixbysix!
If your gonna be using for landscaping, i'd say 4 stoke it! lol or get that techumshe fixed up! I'd start with cleaning like you said. Check your wheelbearings, and after that if you say the chains are ok, i'd run em till they give ya problems. Get some more pictures for us all to check it out and maybe tell ya things to address or look at. As for the picture you posted, a little sanding and im sure the body's color will come back. Now..one thing i DID notice in the picture...the front right wheel looks to be "Cocked" a little?..is this an optical illusion?...or is it really cocked? just look down the side of it from out front or back behind and see if they all seem to be lined up.
as for year of your machine, you'll have to call Recreatives Industries and give them your model number, then they can tell you what year the machine is. Either way, you got yourself a machine with a T20 trans, you'll enjoy it regardless of what you decide to do first. Keep us up to speed on what you do!! Cant wait to see some "Build" pictures! Muhaha!
