OPERATING SUGGESTIONS
There are some important points to remember in order to obtain the best possible results from your
McFarlane harrow.

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 on page 18.

Getting the unit ready for transport includes the following steps:
1.
Rotate the harrow sections up.
2. Swing the wings forward and lock them into the wing rests.

Getting the unit ready for field use includes the following steps:
1.
Unlock the wings from the wing rests and swing the wings out.
2. Rotate the harrow sections down while slowly moving forward, so that the sections lay out
behind the unit properly.

If the wing cables are not tight, adjust the attachment point to the Main Frame to tighten them.
Follow the instructions in the section titled Attach the Wing Cables.

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. Once traveling straight forward again,
lower the sections to the ground.
