I've had a few more thoughts on this subject since my last post. Here in West Central Saskatchewan CAN. your John Deere SF2 Receiver is probably worth between $3,000 - 3,500 CAN. your Mobile processor between $300 - 500 CAN. your GreenStar display between $800 - 1,200 CAN. If I were you, and I'm assuming you donnot wish to sell the parts of the system on the combine (Mass flow sensor, moisture sensor and wiring),then I would not sell the GreenStar display. The reason is that it can still be used on your combine to give yield and moisture readouts making use of the combine components. Also a inexpensive devise called a DataStore can still download Field and Farm _ Yield and Moisture info and print it out using your PC. If the components ( Starfire SF2 receiver and mobile processor) were sold in this area they would probably go to someone wishing to install Autotrack or Accutrack on a Sprayer or Tractor. I hope this is clear and that I am not too longwinded.
