Using Implement Codes

IMPORTANT: Use a scale to check static weight, especially with heavy implements. Static weight remaining on the front wheels with the implement lifted should always be at least 50 percent of the weight with the implement resting on the ground.

Determine the following:

  • Two-wheel drive, MFWD, or MFWD with Independent Link Suspension
  • Front tires with or without liquid

Find implement code in John Deere implement operator's manual.

To find implement code for non-John Deere implements use the following procedure:

1. Estimate implement center of gravity (find or estimate fore-and-aft balance point)

2. Measure distance from implement hitch point to center of gravity. Record the distance (inches). Add 37 to this figure.

3. Determine the implement weight (fully loaded). Record the weight (pounds).

4. Multiply Step 2 by Step 3. Divide by 1000.

5. Resulting number is the implement code.

Use the prior information and refer to the appropriate chart to determine how many QUIK-TATCH ™ weights are required.

causym CAUTION: Do not attempt to transport an implement without adequate front ballast. Loss of steering control may result. With maximum front ballast, do not attempt to transport an implement whose code exceeds:

  • 530 for Two-Wheel Drive

  • 650 for MFWD

  • 835 for 8120, 8220, and 8320 with ILS (Standard Frame)

  • 865 for 8120, 8220, and 8320 with ILS (Long Frame)

  • 865 for 8420 and 8520 with ILS

NOTE: If no quick-coupler is used, add 15 to code.
