Measuring Rear Wheel Slip

LX000402-UN-15AUG94

1. Mark tire (A).

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

3. Drive tractor forward with implement lowered until ten revolutions of the rear wheel have been made (C).

4. Again place a marker on the ground (D).

5. Now raise implement and again drive between the two markers on the ground. Note number of revolutions made between the two markers (E).

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

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