Combine Calculator

The John Deere combine calculator

helps you to bring light into the shadow when it comes to getting facts on the table to optimize your business. It helps you:

to find opportunities to reduce costs (e.g. for wear parts)
increase your profit (e.g. thanks to reduced losses, more grain quality or more straw bales gathered per hectare).

Just select what you want to investigate and follow the instructions.

Your John Deere dealer

is ready to help you to identify margin improvement opportunities for your business in providing professional demonstrations using tools to measure the difference John Deere combines make to your local operation in the field!

What do you want to calculate?

If you calculate the straw yield in tons per hectare this calculator is meant for you. Find out the value of the straw lying on your fields in Euro per hectare. Enter the area you usually bale, the straw yield and the price per ton. After a demo of a John Deere combine you might have noticed that the John Deere combine left more straw behind than your current combine thanks to the unique crop flow concept. If you want to understand what for example 20% more straw means in Euro per hectare just enter “20” next to the respective box. The calculator tells you the additional profit you can have in your pocket in Euro per hectare or on your entire baled area per year!

If you are baling your straw and calculate its value in the number of bales per hectare this calculator is meant for you. Find out the value of the straw lying on your fields in Euro per hectare. Enter the area you usually bale, straw yield and price per bale and the average weight per bale. After a demo of a John Deere combine you might have noticed that the John Deere combine left more straw behind than your current combine thanks to the unique crop flow concept. Simply count the amount of bales on the area harvested by the John Deere combine compared to the area harvested by your current combine. If you want to understand what for example 20% more bales means in Euro per hectare just enter “20” next to the respective box. The calculator tells you the additional profit you can have in your pocket in Euro per hectare or on your entire baled area per year!

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.

The amount of broken grain generated by different combines can be determined using the broken kernel measurement box available at the John Deere dealer. For small grain this tool does follow the norm VO (EG) No. 824/2000 and Norm EN 15587 and for corn it does follow the norm VO (EG) No. 824/2000. All sieves sizes meet the ISO-NF 5223 standard.

How to use the calculator: Enter the type of crop, the area you harvest, grain yield and grain price. Next enter the loss level in percent you do accept. Losses can be measured using e.g. a loss pan provided by Feiffer consult or by following the instructions given in your combines´ s operator manual. Your John Deere dealer is ready to help you determining losses and optimizing your combine as well.

Enter the loss levels of two different combines (for example your current combine and a John Deere combine you had on demonstration) and 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.

For measuring losses we follow the recommendations given on the Feiffer loss measurement system available under www.feiffer-consult.de

Combines are subject to a lot of regular wear on crop engaging parts such as knifes and fingers but also drive chains or belts. The University of Stuttgart Hohenheim has done a combine wear parts cost study published in the German Magazine Bauernblatt to find out how much wear parts costs different combine concepts cause.

According to the above mentioned article the Claas combines in this study had wear parts costs per hectare of 4,03 Euro, the New Holland combines 3,93 Euro and the John Deere combines 2,43 Euro.

Based on your own records or the findings of the study you can compare the costs per hectares and calculate that for the whole lifetime of a combine.
