Unfolding
Unfold the Disk Harrow for adjustments, field operations,
maintenance, parking and storage.
1.
Unless the Disk Harrow was folded, with the
currently hitched tractor, only a short time ago, check
for evidence of oil leaks. Check the ground at hitch
connections, hose fittings and under cylinders.
Crushing Hazard:
Bystanders could be crushed under the wings or caught in the
wing fold mechanisms. To avoid serious injury or death, keep
all persons well away during Disk Harrow unfold.
2.
Be aware of vertical and horizontal clearances
needed to unfold the Disk Harrow.
3.
Put tractor in Park with parking brake engaged.
4.
Clear all persons from on or near the Disk Harrow.

position. Set tractor remote to Neutral to lock at
unfolded.
Folding
Fold the Disk Harrow for movements on public roads and
between fields with narrow clearances.
Electrocution Hazard:
Avoid overhead lines when folding and transporting. When
folded and lifted, the Disk Harrow requires clearance of at
least 14ft (4.3m) for Models 7329 & 7333 and 15ft (4.6m) for
Models 7336, which is high enough to contact low-hanging
lines. Touching the Disk Harrow or tractor completes a circuit
to ground, and can result in serious injury or death. At higher
voltages, shock can occur without direct contact.
