Combines Fieldstar yield sensor

[land_Surfer]

AGCO does use a mass flow system like Ag leader, however, Ag leader uses a "strike" plate attached to a forced transducer (strain gauge),where as the AGCO Fieldstar yield monitoring system uses a two pronged (fork like) attachment to a stran gauge to measure mass flow. Wheaterh one is better over the other remains to be seen. What is more important is the quality of programming that goes into every yield monitoring system to provide the most accurate estimation of yield possible. Remember, a yield monitor is not absolute and nore can they be certified. I think all manufacturers do an admirable job in design and programming to be able to allow all of their systems to competitively reach a consistent 3-5% range margin of error when properly calibrated. Whether you have a system that requires calibrating multiple loads to simulate flow rates, multiple times in opposing conditions, or single loads, the bottom line is it has to be done and if new designs and programming support single load calibration to reach 3-5% error rates consistently to illustrate the critical trends only within a field or part field, then the manufacturer is par for the course. Often times too many folks expect their yield monitors to do too much (i.e., be too accurate = absolute). I have witnessed the frustrated few calibrating their systems daily with auger carts and scales to find out that one too may calibrations puts you back at ground zero, so to say. I have also witnessed those who expect accuracy right off the bat without any calibration and then complain about a faulty_poor quality system.

I've used the 3 prong sensor for 5 years but they are in the process of up dating with a pressure plate similar to Ag leaders with one calibration point.

It's a impact plate design but that's where the similarity ends. It is mounted at the first turn of the grain at the top of the elevator. This combines to make it very linear, allowing a single point calibration, and practically eliminates hillside effects. The story is that it's probably not any more accurate than a well calibrated competitive sensor but should be much easier to calibrate and you shouldn't need to calibrate it very much.

Thanks, very much for your response looks like a good choice for update.
