Measuring Track Slip -MANUALLY

1. Mark drive wheel.

2. With the tractor working, mark a starting point on the ground.

causym CAUTION: Avoid possible personal injury. Stay clear of moving tractor/implement during this procedure.

3. Have an assistant follow tractor and mark ground where drive wheel completes 10 full revolutions.

4. At same working speed go back with implement raised. Line up the drive wheel mark with ground mark, or make a new mark on the drive wheel.

5. With tractor proceeding in a straight line with implement raised, count the revolutions of the drive wheel between the two marks on the ground to the nearest 1/4 track revolution.

6. Use the second count and the chart to determine slippage.

7. Adjust ballast to give 2 to 5 percent slippage.
