Measurements Tab

Note:  Measurements for pull-type implements are entered on the General Information tab. Refer to General Information Tab for details on measurements for these implements.

To view the Measurements tab:

  1. Select the Machine Panel icon in the bottom left corner of the Street Maps view to display the available machine configurations.

  2. Select any of the profile buttons for the machine or implements that are desired to be configured.

  3. Select the larger machine icon near the top of the screen. The General Information tab of the selected machine or implement will display.

    Note:  Use the page navigation at the bottom of the prompt, or swipe across the screen, to access other information for profiles assigned to the selected machine configuration.

  4. Select the Measurements tab to view the Profile Measurements prompt.

GPS Measurements

To provide accurate guidance during field operations, calibrate the ROS for the position of the GPS antenna on the machine relative to the center of the pivot point. Refer to the following sections for assistance with measuring and setting the GPS measurements on the ROS device.

Note:  The pivot point for a conventional tractor or self-propelled sprayer is the center of the rear axle.

Note:  The pivot point for a tracked tractor is the center of the track length between the tracks.

Note:  The pivot point for an articulated tractor is the point of articulation.

Select the left/right offset direction drop-down and select the position of the GPS antenna from the center-line of the machine.

Select the GPS offset distance field and enter the distance from the center-line of the machine to the GPS antenna in inches [centimeters]. The left/right offset distance must be measured perpendicular to the direction of travel.

Select the fore/aft offset direction drop down and select the position of the GPS antenna from the machine pivot point.

Select the GPS offset distance field and enter the distance from the pivot point to the GPS antenna in inches [centimeters]. The fore/aft offset distance must be measured parallel with the direction of travel.

Note:  If offset distance is not correct, there may be line A/B guidance movement on the screen.

The GPS Height value is the measurement from the ground to the bottom of the GPS antenna. The height value will only be necessary if a tilt corrected DGPSClosed Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. signal is provided to the field computer.

Machine and Hitch Measurements

The machine measurement settings provide information about the machine geometry used by ROS to map the vehicle position during field operations and create coverage or as-applied data for field operations.

Select the left/right offset direction drop down and select the position of the machine hitch from the center-line of the machine.

Select the offset distance field and enter the distance from the center-line of the machine to the hitch in inches [centimeters]. Measure the left/right offset distance perpendicular to the direction of travel.

Select the fore/aft offset direction drop down and select the position of the hitch from the machine pivot point.

Select the offset distance field and enter the distance from the pivot point to the hitch in inches [centimeters]. The fore/aft offset distance must be measured parallel with the direction of travel.

The wheel base value is used by ROS to map coverage of the implement during field operations. Enter the distance between the front and rear “axle” in inches [centimeters]. The wheel base must be measured parallel with the direction of travel.

For articulated vehicles, measure the distance from the pivot point to the front axle.

For articulated vehicles, measure the distance from the pivot point to the rear axle.
