I found a 2182 Super Garden Tractor I believe. I have never owned a SGT and have some questions. I have been watching it where it sat on a property for the whole summer and I left a note asking if it was for sale and got a call about it last night. It has a Kubota 3 cyl gas engine and a cat 0 3point hitch and rear Pto and a 60" Haban mower deck. There is also a tiller available with it that runs off the rear Pto. Is the 2182 a good tractor? I'm going to look at it today to acess it's condition and mabe make an offer on it. At this time it has no battery in it so I may bring one with to attemp to start it. I was told it runs and drives and works as it should when he parked it. Any special things to look for on this machine? What would be a fair value of this machine? I will have some pics in a few hours when I go look at it. I mostly am interested in the tractor and the mower deck, anyone have any idea of aproximatly what it is worth? I want it but not bad enough to overpay for it. Also what is a rear tiller that is driven off the rear Pto of the 2182 worth?? Thank you for any help and opinions.
