Straight Track Mode


Theory of Operation

PC9508
PC9508-UN-24OCT06

Passes are identical copies of the original pass.

Straight Track mode assists operator in driving straight parallel paths by using display and audible tones to alert operator when machine is off track.

Straight Track allows the operator to create an initial straight track using various different track 0 options. Once the Track 0 (reference path) has been defined, all passes for the field are generated. The generated passes can be used to operate Parallel Tracking or AutoTrac.

NOTE: Track 0 and A—B lines are two terms used interchangeably, we will use term Track 0.

Track 0 is the reference point from which all parallel passes in field are based. Use the following procedures to set up Track 0 and Track Spacing.

Creating Track 0

  1. Guidance Settings tab—Select Straight Track mode.

  2. View tab—Press Set Track 0.

  3. Press New button below the Current Track 0 drop-down box.

  4. Enter a name for Track 0 using the alphanumeric keypad

  5. Press Accept button.

  6. Select method to define Track 0 from Method drop-down box.

    • A + B
    • A + Heading
    • Auto B
    • Lat / Lon
    • Lat / Lon + Heading

    Methods of defining Track 0 are explained later in this section.

  7. Choose which guidance line calculation is preferred.

  8. Set Track Spacing

    Track spacing can be defined two different ways:

    • Select track spacing button from Set Track 0 dialog box
      • Enter implement width
      • Enter desired track spacing
      NOTE: A higher degree of precision can be achieved for track spacing when track spacing is entered in by rows instead of feet. More decimal places are used in the track spacing calculation when entered in by rows versus the three decimal places allowed when entered by feet. Select (ft)/(rows) button to change to rows.
    • Set track spacing from Equipment softkey > Implement 1 tab > (See Equipment softkey section.)

    NOTE: A distance of 15 m (45 ft) or longer must be driven before point B can be defined. This method calculates point B from the last five data points taken from the 15 m (45 ft) driven and runs a best fit line through the points to determine a heading.

  4. The B—point will automatically be saved after traveling 15 m (45 ft).

Guidance Line Calculation allows an operator to create new Straight Track guidance lines on their GreenStar 3 2630 display using non-John Deere calculations. Throughout the industry, there are different calculations used for creating straight tracks. This feature allows an operator to choose a calculation type.

Non-John Deere 1: Uses BEELINE calculations when creating a Straight Track.

Non-John Deere 2: Uses Trimble® calculations when creating a Straight Track.

This feature is only supported when creating new Straight Track guidance lines. All methods for creating a new straight track are supported, but A+B method is recommended when creating new guidance lines based on crop rows or beds that were previously made with a competitive system. Using the same A+ Heading as a competitive system will not result in desired performance.

Guidance Line Calculation defaults to John Deere (H). Select Non-John Deere 1 (I) or Non-John Deere 2 (J) from Guidance Line Calculation drop-down box (E) to change calculation.

NOTE: To create John Deere guidance lines, use default calculation of John Deere.

This feature does not allow an operator to import competitive guidance lines.

Guidance Line Calculation is only supported when Straight Track mode is selected.

Guidance Line Calculation feature does not affect previous guidance lines.

Guidance Line Calculation cannot be changed on previously created and saved guidance lines.
