Your right, they are sold under many names. Closest I can find to this is a Husqvana LT2216 I think. Twin deck, solid cutters not swing backs, steers good, hydrostatic 6 speed. Not a bad machine. But I know what she's been through. I have fond memories of a 4" galvanised pipe socket flying out the discharge chute one day and the ensueing speed wobbles from the blades once they were mangled to near irreparable!!
I wouldn't say no to the machine, but I'd definitely make them pay for all the parts spent on the greenfield if they did want to trade!
