Hi I have a running engine for a b6000 for sale. Runs well for its age, no smoke while it's running, comes with muffler, air cleaner, dyno, starter. Does not include the hydraulic pump, radiator, fuel filter, electric fuel pump, pressure plate & clutch parts. It's still in the tractor so you can hear it run if you like. $1250.00 I prefer not to ship only because I wouldn't know where to start.
