I just purchased a Zetor 6745 on the basic of a brief description and two sketchy photos for $NZ2000 ($US1400). The shipping is going to cost around $500 since it is 400km away.
Apparently there is a broken PTO shaft and it comes with a spare.
I am planning on using it for baling hay along with the Welger AP71 baler that I own, which is 2 tonnes worth of German engineering.
Before hay season (January - March) I will need to fix the clutch and brakes, change all of the fluids and fix the PTO.
