Transporting the Disk
Harrow
Loss of Control Hazard:
Do not tow the disk harrow behind another implement on
public roads. Tow the disk harrow to the field with a separate
vehicle. The leading implement may not provide sufficient
lateral control of a trailing implement at highway speeds. The
total weight of the train can also exceed the steering and/or
braking capability of the tractor. The resulting accident could
cause serious injury or death.
Loss of Control Hazard:
Use an adequate towing vehicle. Never tow an implement that
weights more than 150% of the towing vehicle (transport
vehicle must weight at least 67% of implement). Ensure that
the towing vehicle is adequate for the task. Using an
inadequate tow vehicle is extremely unsafe, and can result in
loss of control, serious injury and death.
Note: See tables on page 31 for Disk Harrow transport
weights.
Braking and Loss of Control Hazard:
Do not exceed 25/30 mph (40/48 km/h) when driving straight.
Slow down on rough roads.
Do not exceed 13 mph (21 km/h) in turns. The weight of the
Disk Harrow can cause under-steer, and the height of the Disk
Harrow is a tipping hazard.
Transport Checklist
Know your implement weight. If tractor capabilities are
marginal, chack actual weight of implement at a scale.
Before transporting the Disk Harrow check the following
items.
1. Check that implement is securely hitched to a suffi-
cient tractor (page 13).
2. Always use a locking-style hitch pin sized to match
holes in hitch and draw-bar, and rated for the load.
3. Attach safety chain to tractor with enough slack to
permit turning (page 13).
4. Verify correct operation of lights.
5. Check that tires are properly inflated (page 33).
6. Plan the route. Avoid steep hills.
7. Always have lights on for highway operation.
8. Do not exceed 20 mph (32 kph). Comply with all
national, regional and local laws when traveling on
public roads.
9. Remember that the implement may be wider than
the towing vehicle. Allow safe clearance.
