SAFETY SIGNS AND DECALS
LOCATED AT TOP OF AUGER CENTER TUBE
LOCATED ON POST HOLE DIGGER BOOM
REMEMBER: If Safety Signs have been damaged, removed, become illegible or parts replaced without Signs, new
Safety Signs must be applied. New Safety Signs are available from your authorized distributor or factory.
INSTRUCTIONS (continued)
Once the auger is digging a hole, the tractor cannot be
moved. Make sure brake is set securely. If the tractor
does move while the auger is in a hole, damage to the
gearbox or auger can result (not covered by
warranty).
Cutting edges and screw type center point are replace-
able. They should be sharpened or replaced when worn.
In hard digging conditions, a fishtail type center point is
more aggressive and is recommended.
NOTE: Be sure auger is completely retracted from
the hole before attempting to move the tractor.
NOTE: If you have a rocky or large root soil condition, it
is recommended that a heavy duty auger by used.
If you encounter rocks or roots that catch the auger and
cause shear bolts to break, then remove the auger from
the hole and use a large, heavy pry bar to break up the
obstructing rock. A large root may have to be chopped to
remove.
NOTE: Please refer to the drawings (Figures B through
F) as to the proper mounting pattern for the cutting
edges. Correct mounting of the cutting edges will assure
a complete cut of earth by the auger.
If auger becomes lodged below ground, DO NOT
attempt to lift auger out of ground by hydraulic lift power
alone. Turn tractor off and disconnect PTO driveline from
the tractor. Reverse the rotation of the auger by several
turns. This can be accomplished by using a large pipe
wrench and screwing the auger backwards until it clears.
Extreme rocking or lifting loads while trying to clear stuck
augers can cause auger, gearbox, or boom failure.
Remain on the tractor seat while operating the post
hole digger. Assisting the machine by hand can
result in possible injury or death.
W ARNING!
Do not attempt to free the auger while the PTO is
connected. Disconnect the PTO driveline from the
tractor before attempting to free the auger.
CAUTION!
Underground utilities – Contact appropriate
agencies to determine if hazardous items are buried
under the digging site BEFORE DIGGING! Be certain
underground utilities have been called to locate
underground electric, gas, telephone, and other
lines. Check your telephone book for calling instruc-
tions. Be sure post hole digger operator is properly
informed. WHEN IN DOUBT, DO NOT DIG!
CAUTION!
NOTE: Be careful when raising the auger as high
as your tractor’s 3-pt. hitch can go. This can put
the PTO shaft universal joints at an extreme
angle and cause damage to the PTO shaft! It is
best to raise the auger just enough to clear the
hole when the PTO is engaged.
It is recommended NOT to raise the auger while
it is running more than six (6) inches above the
ground.
Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped out
by a single careless act of an operator.
It has been said, “The best safety device is an
informed, careful operator.” We ask you to be that
kind of an operator.
NOTE: Never exceed the recommended auger
capacity of the post hole digger. The Model 720
heavy duty digger is designed for use with augers up
to 24-inch diameter. Use of an incorrect auger or
auger extension can cause equipment damage, loss
of operator control and personal injury.
