Refer to the layout diagrams in appendix C
for the locations of the different lengths of stabilizer
angles. Bolt the stabilizer angles to the bolt plates near the rear end of the lift arms. Refer to
Figure 14.
Use 7/16” x 1 1/4” bolts, lock washers, flat washers and hex nuts.
Figure 14
Angle of Attack
Before actually placing the harrows, you many want to determine the ‘angle of attack’ desired for
your particular application. Refer to Figure 15 to help clarify what is meant by ‘angle of attack.’
McFarlane flexible harrow sections have a built-in system which allows the harrow owner a choice
between a steep or shallow angle of attack. To change the angle of attack, simply reverse the harrow
section and pull it from the other end.
Each angle has its advantages and disadvantages. The steeper angle of attack is for more aggressive
harrowing. However, the steeper the angle, the greater the tendency there is for the sections to clog
with field debris.
Be sure all adjoining harrow sections are set to the same angle. Each section is matched to the one
next to it and may become entangled if the angle settings do not match. It may be desirable to set the
front sections (8-bar on a 16-bar harrow) aggressive and the rear sections less aggressive.
