Combine Calculator

Grain quality and specifically the amount of broken grain in the sample is not only an important factor for seed producers or those who have get deductions for excessive broken grain amounts at the elevator. Research in Germany done by Feiffer consult in 2004 in Hungary in wheat has shown that out of the total amount of broken grain a combine is generating only up to 50 % can be found in the grain tank and 50 % end up as losses in the field. As broken kernels do not germinate anymore those losses cannot anymore identified as green stripes of germinated grain losses later in the season.

That means if you have 3% broken grain identified in the grain tank up to 3% can be found in the field as well.

How to use the calculator:

Enter the type of crop, the area you harvest, grain yield and grain price. Next enter the amount of broken grain in a sample. This can be identified at the local elevator or using a special box available at your John Deere dealer to analyze the amount of broken grain according to international standards.

Under the assumption that 50% of broken grain ends up in the grain tank and 50% is left on the ground the calculator gives you the profit you leave in the field in Euro per hectare and on the total area per year for that crop. It also tells you the difference between two samples. This can be for example a sample of your current combine and a sample of a John Deere combine you had on demonstration.
