REAR WHEEL TREAD ADJUSTMENT
IMPORTANT: Before making any adjustment make sure that the tractor is correctly supported. Apply the park
brake and put blocks in front of and behind both front wheels and the other rear wheel. Check torques after the
first 30 minutes of operation and then every 10 hours of operation until torques stabilize. This tightening and
checking procedure is necessary after any wheel repositioning operation, see “REAR WHEEL BOLT
TORQUES” on page 184 for correct torques and tightening sequence.
