Section 1 Safety Rules

Section 1 Safety Rules

Most accidents are the result of negligence and care­lessness, usually caused by failure of the operator to
follow simple but necessary safety precautions. The fol­lowingsafetyprecautions are suggested to help prevent
such accidents. The safeoperation of any machinery is
a big concern to consumers and manufactures.Your All
SeedsHitch has beendesignedwithmany built-insafety
features. However, no one should operate this product
before carefully reading this Operators Manual.

!

General Operation & Repair

1. Never permit anyone to ride on or walk beside the drill,
planter, or tillage equipment when moving.

2. Never permit anyone to ride on tractor, drill, planter or
hitch when they are being moved.

3. Never allow anyone to be near the drill or planter when
performing operating functions with the drill, planter,
hitch, or tractor.

4. Never load the drill or planter without being hooked up
to a tractor.

5. Always make sure the drill and planter are securely
locked in the quick hitch before raising.

6. Always put the transport lock lever into the transport
“Road” position and make sure transport lock blocks
havesnapped intotheir locked positionimmediately after
raising the unit for transporting and before making
adjustments.

7. Nevertransport the AllSeeds Hitch withoutthe pivot lock
tubes (correctly adjusted), and in the horizontal (locked)
position. The pivot lock tubes are located above and out­side of the leaf springs. The lock tubes will lock automat­ically when the unit is raised, unless they are manually
pinned in the vertical position.

8. Extra care should be taken when transporting with seed
in the box or hoppers.

9. Reduce speed of the tractor when transporting over un­even or rough terrain, hills or steep slopes. Avoid all
chuck holes and washboard areas in roads.

10. Do not pull the All Seeds Hitch faster than 20 miles per
hour.

11. Never turn a shorter radiusthan the All SeedsHitch pivot
stops will allow.

12. When in transport, use accessory lights and devices for
adequate warning to operators of other vehicles and use
safety hitch chain. Comply with all federal, state and lo­cal laws when traveling on public roads.

13. Use “slow moving vehicle” emblem for warning vehicles
approaching from the rear.

14. When transporting, remember the All Seeds Hitch is wid­er than your tractor and extreme care must be taken to
allow for safe clearance.

15. Never back up with the drill openers, planter openers or
coulters in the ground.

16. Always set the drill or planter in the field position before
lubrication, making adjustments, or servicing. Periodi­cally check bolts for tightness and lubricate all fittings.

17. Do not lubricate or adjust the drill or planter while it is
in operation.

18. Do not permit smoking, sparks, or an open flame where
combustible lubricants or liquids are being used.

19. When using treated seed, avoid direct contact with the
seed. Do not breath or ingest chemicals.

20. When using compressed air to clean the drill boxes or
planter hoppers wear safety glasses.

21. Never unhook hitch from tractor when attached to a
raised drill or planter.

22. Escaping fluid under pressure can have sufficient force
to penetrate the skin. Check all hydraulic lines and hoses
before applying pressure. Fluid escaping from a very
small hole can be almost invisible. Use paper or card­board, not body parts, to check for suspected leaks. If in­jured, seek medical assistance from a doctor that is
familiar with this type of injury. Foreign fluids in the tis­sue must be surgically removed within a few hours or
gangrene will result.

23. Do not allow anyone to operate the machine who has not
been properly trained in its safe operation.

24. Consult your drill operator’s manual for safe drill oper­ation.

25. Consult your planter operator’s manual for safe planter
operation.

26. Do not operate equipment while under the influence of
drugs or alcohol.

27. Keep hands, feet, hair, and clothing away from all mov­ing parts.

28. Clear the area of bystanders, especially small children
and animals before moving or operating equipment.

29. Support implement with blocks or safety stands when
changing tires or working on equipment.

30. Review the Safety instructions annually.

Safety Decals

1. Your All Seeds Hitch comes equipped with all safety de­cals in place. They were designed to help you safely op­erate your All Seeds Hitch. Read and follow their
directions.

2. Keep safety decals clean and legible.

3. Replace all damaged or missing safety decals. To order
new safety decals go to your Great Plains Dealer and or­derpart no. 148-179A. Refer tothe parts section for Allde­cals package part numbers.

4. Replace these decals whenever they become worn or un­readable. To instal new safety decals:

a. Clean the area the decal is to be placed
b. Peel backing from the decal. Press firmly on to sur-

face being careful not to cause air bubbles under the
decal.
