Combines loup Yield MonitorIJ

[Ilnewholland]

I went ahead and got the yield monitor today, so I will see how it works. To measure the grain right the company guy said they send a small T.W. scale to check the TW. If you change numbers of corn and the TW changes you have to enter it into the unit. You don't have to weigh loads of grain, just check the TW. Wish me luck in putting this thing on the combine, any helpersIJ Ilnh

To properly calibrate this type_brand (same as the lexion) of volumetric yield monitor, you will first need to zero out the yield sensor (measure the thickness the of the elevator paddles at full speed),zero out the slope sensor on zero grade, weigh a batch (a part of or a whole grain tank load or even a truck load) and enter the difference, in wet yield only, to reset the calibration factor. The test weight, measured with the hand-held scale and graduated cylinder, is of no use until the full calibration, described above, is performed (need to have a base to operate from). To maintain accuracy, periodic checks of the grain's test weight with the scale and cylinder is necessary. Test weight can change between: varieties, tillage practices, time of day, humidity, etc. I check test weight a minimum of 4 times per day (takes only seconds to do). However, if you perform the full calibration and at the same time adjust the test weight, you will void the accuracy of the full calibration since you accounted for it when you entered the difference in bushels. The test weight procedure is for maintenance checks only. The lope, RDS and ClAAS yield monitors are all the same, with the same calibration and off-set procedures.

As I discussed further down the page, this is a volumetric monitor. I quess I should have said if they have a way to input TW when it changes it should be fairly accurate. The adjustment is a simple formula and inputing the correct TW will greatly improve accuracy. Good luck. I am fully supportive of producers who spet up and try new things. This will force Al and OEM to keep prices in line. BTW- I purchased one of the first 100 Al on the market his first year and have been following this niche market since then. The NH radio and AGCO radioactive unit, if ever perfected in the US will be the best.

The elevator paddles need to be flat and rigid for this type of light beam volumetric sensor to be most accurate. If paddles deflect or curl downward under load, this will disrupt light beam and be interpreted as "more grain" on each paddle. Hence the lexion elevator paddles are stiffer and backed up by a steel plate around 2_3s of the back side of each. Also, accuracy is enhanced by having a relatively narrow elevator with a relatively tall pile of grain, hence the relatively narrow elevators on lexions. Same principle as applied to rain guages with an enlarged funnel on top filling into a smaller beaker. The graduations are further apart and actual volume can be read more accurately. landsurfer, I do think the method of measuring yield does have a large impact on final yield data. A worn impact sensor on JD, CIH etc, or a dirty or damaged lens on a light sensor will cause errors in the measurement and correlated errors in yield data reports. AGV

JD, Are you thinking of the RDS systemIJ They were at a local farmshow a few years ago. Agleader is the big system here unless you use Greenstar or AFS. thanks Peter
