Machinery Sizing

Quickly estimate tractor horsepower to pull various implements. No more standing at farm auctions wondering if your tractor could pull an implement for sale. The application has a built in list of many common implements. You can select ground and soil conditions, tractor type, pulling speed, working depth and size of the implement. Then hit calculate and the application will provide an estimate for the required drawbar and PTO horsepower.

Note:
This app provides two horsepower measurements. Drawbar horsepower is the horsepower to pull the implement. PTO horsepower is the actual tractor horsepower you need based on tractor type and soil. Use PTO horsepower to match tractors to implements.

How to use:
Select implement, tractor, and soil details from the menus. After changing values any selection, please hit select to make sure the horsepower is updated. It will try to update as you type numbers, but this may not work consistently every time, so hit calculate to make sure the app knows you changed something.

This application and its information are based on a spreadsheet maintained by Dr. Randy Price of the Biological and Agricultural Engineering Department for the Research and Extension Service of Kansas State University.
