Joe L., Wayne is correct, the wide tires were optional, as were attachments like mower decks. No way to tell what it came with unless you have the original bill of sale. Other optional items are lights, electric lift, the rear lift, wheel weights and cigarette lighter. The 1000 would be the same chassis as an 800 and a 1200 except for the engine and of course, decals. The drive line should be the same for all three. Attachments from a 1x8/9 and any Quiet Line series (800 through the 1650) should fit it. BTW I did get your email I will respond on Monday from my work PC rather than from webmail.
