Combines how precise is yield mappingIJ

[thud]

Yes a properly installed yield monitor will make up for these 'delays'. Assuming you have the correct 'unit' installed there is no problem.

Plug in your offset, swath and cal. the best you can and you'll get along with your data fine. You have to remember that yield mapping from monitors are just giving you points of relativity in that field. They are great tools but some are using them for cash rents which anybody knows cal. numbers can be used for and against your objective.

Dakota, At a combine clinic a while back they told us that on a 2388 it take a kernal of grain about 14 seconds to go from the cutter bar to the grain tank, so the yield mapping has about a 14 second delay calibrated into it. I guess each make and the size of the combine would determine how the yield mapping is calibrated. K.A

The readout on the yield monitor in the field and the data you collect and store on a memory card to make maps are two different things First the readout in the field is a 10 sec moving average (in the Agleader) of yield so that when you slow down or stop the yield doesn't to to infinity. The data stored on the card repersents snap shots at what ever data logging interval you select. 1,2,or 3 secs. This data is what the yield monitor observed in that time frame.distance traveled, time,lb. of grain harvested, width of header, gps position in the field. It is in the software where the time delay is used so that the data when placed on the map is placed backward to the position where you were when the grain was cut. The gleaner seem to be 12 sec. This can be calabrated in cereals very easy by cutting a swath across the normal harvesting direction. Then in the software you change the time delay until the swath looks like a missed section in the field with no uneven sides. Hope this explains the slow responce you see in the yield monitor readout Best of the Season Bruce
