MAINTENANCE AND SERVICE SCHEDULE

Prior to each use, check for loose bolts and replace lost or worn parts.

Grease hinge pins before each use when necessary.
Note: Clean grease fittings and replace those that are broken or missing.

Inspect and repack wheel bearings at the beginning of each year.

Remove dirt and debris from the harrow sections before storage.

Parts diagrams and listings for service and repair references may be found in appendix B.
OPERATING SUGGESTIONS

To maximize the harrow’s performance, it should be towed at speeds ranging from six to nine (6
- 9) mph. This keeps the field debris moving through the harrow sections and avoids clogging.
The best results will be obtained after the paint has been scoured from the teeth.

Choose the angle of attack of the harrow teeth based on field conditions. For more information
see the section titled Angle of Attack.

Getting the unit ready for field use includes the following steps:
1.
Move the cylinder lock bars to storage position. See Figure 5 on page 18.
2. Disconnect the tie-bar on the left side and swing it forward and pin it to the stow bracket.
3. Using the transport hydraulics rotate the transport wheels half way into field position,
approximately 45°. Slowly back up until the wings are even with the center bar and the pull
tube contacts the lock arm. As you back up, be sure the wings open evenly. Rotate the
transport wheels fully into the field position.
4. Rotate the toolbar down into field position only until the lock arm engages the pull tube and
locks it into place.
5. Drive forward and lower the unit into the field position.

Getting the unit ready for transport includes the following steps:
1.
Rotate the harrows to the upright position.
2. Using the transport hydraulics rotate the transport wheels half way into field position,
approximately 45°. Slowly drive forward until the wings are straight back behind the unit.
3. Rotate the transport wheels fully into the transport position.
4. Rotate the cylinder lock bars back into the lock position. Same as number 1 above.
5. Connect the tie-bar between the two wings.

Field Operation - while turning on the headlands (field ends) slow down and rotate the toolbar up
so the harrow sections begin to lift off the ground. Be sure not to rotate the toolbar too far,
otherwise the pull tube lock will disengage and the wings will fold backwards resulting in severe
damage. Once traveling straight forward again, lower the sections to the ground.
