Nel, after reading the comments I sugest you get with a NH tech rep to explain it factually. I had a CR940 all last summer and had very good luck with it. Only one minor idler pulley bearing on the serpentine belt failed. I used it some 200 hours, and was very!!! happy. I was runnig along side my TR-99. If I were to buy one I would put a Ag leader yield monitor on it. Not becuase Al is better, but the NH info monitor needs to be watching machine peformance such as rotor loss, grain loss, volume of retailings, percent of power being used, etc. The Al could then monitor theyield functions. The calibration of the NH is easy and was quite accurate even with calibrating with one crop-wheat. You can e-mail tech support too for info and advise. Don
