Measuring Wheel Slip-Manually

NOTE: Tractors equipped with optional radar unit can automatically determine the percentage of wheel slip. Radar must be calibrated correctly. (See Controls and Instruments Section).

1. Mark a rear tire.

2. Mark a starting point on the ground with the tractor moving and implement lowered in the ground.

3. Follow tractor and mark the ground again where marked tire completes 10 full revolutions.

4. Repeat procedure with implement raised at the same working speed. Count revolutions between same two marks.

5. Use second count and chart to determine slippage. (8-12 percent is ideal.)

6. Adjust ballast or load to give correct slippage.
