Hitching Disk Harrow to Tractor
Hitch to a tractor for highway transport or field opera-
tions. Hitch to a leading implement only for field opera-
tions. Do not transport behind another implement.
Before hitching, check the compatibility and capability of
the towing tractor or implement:
• The 3323-4336DH Disk Harrow is a pull-type imple-
ment equipped with a standard Category IV single
tang hitch. It may be converted to a Category III or
clevis hitch using supplied accessory parts.
To prevent soil compaction on rows, set tractor wheels
between rows. For hillsides and steep slopes, set tractor
wheels as wide as possible for maximum stability.
1.
Raise tractor three-point arms (if equipped) clear up
to clear Disk Harrow.
2.
For TWO-WHEEL DRIVE and MFWD tractors, pin
drawbar in fixed center position for field and trans-
port. For FOUR-WHEEL DRIVE and TRAC-DRIVE
tractors, leave one hole clearance on each side of
drawbar for field position, hitch damage may occur if
pinned solid. Pin in center position for transport to
maintain maximum steering control.

Negative Tongue Weight Hazard:

tor or leading implement before unfolding. An unhitched disk
harrow can tip over backwards during folding and unfolding
if the tongue is not secured.
6.
Secure safety chain to an anchor on the tractor.
