Measure Rear Wheel Slip

LX000402-UN-15AUG94

1. Mark tire (A).

2. Mark starting point on the ground (B).

3. With the implement lowered, drive until the rear wheel has completed 10 revolutions (C).

4. Place a marker on the ground at that point (D).

5. Drive the distance between the ground markings again with implement raised and count the revolutions of the rear wheels (E).

   The number of revolutions gives the following percentage of wheel slip:

   • 10.0 revolutions = 0% wheel slip
   • 9.5 revolutions = 5% wheel slip
   • 9.0 revolutions = 10% wheel slip
   • 8.5 revolutions = 15% wheel slip
   • 8.0 revolutions = 20% wheel slip
   • 7.5 revolutions = 25% wheel slip
   • 7.0 revolutions = 30% wheel slip
   
   

NOTE: On tractors with GPS or radar sensor, the slip indicator in the display can be used. The calibration of the radar sensor needs to be observed.
