I have a GT 3000 that I got about 2 years ago for $650 ( was asking $800) from some guy who had only a quarter acre , big tractor for such a small property I think; anyway, he was moving and wanted to get rid of it quick. The problem was it had a gas tank leak. It is a bigger riding mower with the tank under the seat.I got a new tank from Sears but does anyone have any advice on removing and replacing the tank rear fender seat etc? I was reading an earlier thread that someone said it was made by John Deere for Sears. Anyone have any info on that cross over model?
