John Deere Gator 6x4?

I’d put that money towards another newer sxs. I’d almost bet some parts are discontinued on that unit already.

Start with the carb parts.

My aunt and uncle had one when I was a teen, it was an absolute tank and you could stomp the throttle to the floor and it would just slowly spool up, but nothing better get in the way. We never towed with it but I’m sure it could pull a ton. Sounds just about perfect for what you’d want it for.

I wouldn’t get too discouraged over the age versus parts. Those older machines are overbuilt and just shouldn’t need much other than routine maintenance as long as they aren’t abused. Filters, fluids, and such will have equivalents that can be used. There’s knockoff parts of every major brand available for machines going back to the 80s, and in most cases the OEM will be available if you need it. Carb parts are the most likely to be needed and in most cases interchange between makes or a very wide range of years. I stripped a 1999 Yamaha to the frame and could have replaced every wear part but the decals and plastics with OEM if I’d chosen to. Call a Deere dealer and just ask if they have issues with older gators and they’re likely to tell you it’s no different than sourcing parts for anything else.
