IMPORTANT: Make sure that tire pressures are set for axle loads before measuring wheel slip.

  1. Mark a rear tire.

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

  3. Follow machine and mark ground again where marked tire completes ten full revolutions.

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

  5. Use second count and chart to determine slippage.

    NOTE: Ideal slippage is 8—12% (machines with MFWD).

  6. Adjust ballast or load to give correct slippage.

    NOTE: Available horsepower is greatly reduced when wheel slip drops below minimum percent.
