Haulmaster Connect
Business
Free
Designed for use with an Elmer's Haulmaster Grain Cart equipped with Haulmaster Connect or Haulmaster PRO. Some features of the app are not available until the device is connected to the Haulmaster controller's Wi-Fi.
While connected to your cart, you can:
* See the weight of your cart
* Edit the active field, truck, bin, and crop
* See various machine parameters like individual load cell readings (HM CONNECT or PRO), machine sensor readings (HM PRO only), and auger hours (HM PRO only)
* Control the hydraulic functions on the grain cart (HM PRO only)
* Calibrate and customize the hydraulic flow and angle sensors (HM PRO only)
Anytime, you can:
* View unload history for the last cart you were connected to, including field totals and past season information
* Queue edits to/creation of farm information and unloads that will be applied next time you connect to your cart
* Import farm data from John Deere Operations Center or a .csv file that will be applied next time you connect to your cart
