Safety is a primary concern in the design, manufacture, sale, and use of Post Hole Diggers. As manufacturers of Post
Hole Diggers, we want to confirm to you, our customers, our concern for safety.
Our current production machines include, as standard equipment, guards or shields for auger adapters, drivelines,
input shafts, and safety signs. Older machines can be retrofitted to add these new guards or shields and, or course,
safety signs. If you have an older machine which does not have current standard safety equipment, please contact
your dealer about bringing your machine up to the current level of safety.
SAFETY INSTRUCTIONS (continued)
MAINTENANCE SAFETY (continued)
Never work under equipment unless it is blocked securely. Never depend on hydraulic system to keep imple-
ment in raised position.
Always use two people to handle heavy, unwieldy components during assembly, installation, removal, or
moving the digger.
Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended
during assembly, installation, operation, adjustment, maintaining, repairing, removal, or moving the digger. Do
not allow long hair, loose fitting clothing or jewelry to be around moving parts.
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
Always use personal protection devices such as eye, hand and hearing protectors, when performing any
service or maintenance.
Periodically tighten all bolts, nuts and screws and check that all cotter pins are properly installed to ensure unit
is in a safe condition.
When completing a maintenance or service function, make sure all safety shields and devices are installed
before placing unit in service.
Never use your hands to locate a hydraulic leak on attachments. Use a small piece of cardboard or wood.
Hydraulic fluid escaping under pressure can penetrate the skin. Openings in the skin and minor cuts are
susceptible to infection from hydraulic fluid. If injured by escaping hydraulic fluid, see a doctor at once.
Gangrene and death can result. Without immediate medical treatment, serious infection and reactions can
occur.
Where replacement parts are necessary for periodic maintenance and servicing, genuine factory replacement
parts must be used to restore your equipment to original specifications. The manufacturer will not claim
responsibility for use of unapproved parts and/or accessories and other damages as a result of their use.
If equipment has been altered in any way from original design, the manufacturer does not accept any liability
for injury or warranty.
TROUBLESHOOTING GUIDE
PROBLEM: AUGER WILL NOT DIG
Possible Solutions:
• Shear bolt sheared – install new shearbolt.
• Teeth dull – sharpen or replace.
• Ground too dry and hard – order optional fishtail point
(#170802) or optional down force kit, or wait until it
rains.
• Auger turning too fast and bouncing – reduce speed.
• Tall grass has wrapped around auger teeth – remove.
• Auger encountering rocks, roots, or other obstruction –
lift auger from hole and inspect.
• Auger teeth improperly positioned – see operator’s
manual for proper tooth pattern.
PROBLEM: AUGER DIGS SO FAR, BUT WILL NOT
DIG DEEPER
Possible Solutions:
• See solutions for above.
• PTO assembly “bottoms out,” not allowing digger to
lower – remove auger from digger and lower digger.
Gearbox should lower to the ground; if not, PTO
driveline assembly may need to be shortened.
• PTO driveline interferes with swinging drawbar – swing
drawbar out of the way or remove.
• Tractor hydraulic system may be faulty – consult trac-
tor dealer.
• Soil could have hardpan layer 6”-10” below surface –
use optional fishtail point (#170802) or optional down
force kit (see list of optional equipment).
PROBLEM: POST HOLE DIGGER SWAYS SIDE TO
SIDE
Possible Solutions:
• No sway bars or sway blocks on tractor – add same.
• Lift arms not adjusted evenly – adjust lift arms.
• Post hole digger is mounted with excessive looseness
in the hitch connecting points – use proper size pins or
bushings.
PROBLEM: BENT AUGER FLIGHTING OR BENT
AUGER
Possible Solutions:
• Tractor moved while auger was turning in hole –
always set brakes on tractor and make sure it is out
of gear.
• Operator moved tractor with auger in hole to try and
straighten a hole being dug at an angle.
• Auger is encountering rocks or roots or other foreign
objects – remove object from hole or change location.
• Outer edge of auger flighting is bending due to contact
with rocks or roots – use heavy duty auger with thicker
flighting.
• Shear bolt has been replaced with harder bolt –
replace with Grade 2 bolt per instructions.
THIS IS A DANGEROUS SAFETY HAZARD,
CORRECT IMMEDIATELY!
PROBLEM: AUGER SCREWS ITSELF INTO THE
GROUND
Possible Solutions:
• Operator did NOT ease 3-pt. hitch to ground slowly.
• Faulty 3-pt. hitch hydraulic system on tractor.
• Draft control is not in OFF position.
• Tractor is too small to handle digger.
PROBLEM: EXCESSIVE VIBRATION
Possible Solutions:
• PTO driveline halves are mis-aligned. Pull PTO drive-
line halves apart and reassemble. Make sure end
yokes are aligned correctly.
• PTO driveline bearing cross is worn – replace.
PROBLEM: PTO DRIVELINE ASSEMBLY COMES
OFF INPUT SHAFT OF GEARBOX
WHEN SHEAR BOLT IS SHEARED.
Possible Solution:
• Roll pin missing in yoke at gearbox input shaft. Install
roll pin as per instructions.
W ARNING!
