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 respon-
sibility 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.
TROUBLE-SHOOTING GUIDE
(continued)
PROBLEM: PTO DRIVELINE FAILURE
Possible Solutions:
• Operator raising post hole digger too high above
ground when PTO is engaged – causes excessive PTO
joint operating angle.
• PTO is engaged while moving between holes. (Auger
swings, which causes excessive PTO joint operating
angle.)
• Improper use of a hard shearbolt – use Grade 2 bolt
per instructions.
• Driveline has not been properly lubricated.
• Engaging tractor PTO with engine at high rpm.
• Digging holes too deep so that PTO driveline contacts
ground.
• Operating at high rpm.
• Use of auger extension can require post hole digger to
be lifted high, which can cause excessive PTO joint
operating angle.
• Tractor is a “low profile model” (one that is low to the
ground). Due to the low height of the tractor, the digger
must be raised higher to have the bottom of the auger
clear the ground. Generally, low profile model tractors
can only use 30 inch long augers (standard auger
length is 42”). Use a different tractor or purchase 30”
long augers.
PROBLEM: PTO DRIVELINE “GALLS” OR “FRIC-
TION WELDS” TO INPUT SHAFT OF
GEARBOX
Possible Solution:
• No lubrication on input shaft of gearbox to allow yoke
of PTO driveline to turn freely on input shaft when
shear bolt is sheared. Always keep input shaft greased.
PROBLEM: GEARBOX FAILURE
Possible Solutions:
• No oil in gearbox.
• Oil not changed per instructions.
• Shear bolt has been replaced with a harder bolt –
replace with Grade 2 per instructions.
• Bent output shaft is due to operator moving tractor
when auger is in hole.
PROBLEM: GEARBOX OVERHEATING
Possible Solutions:
• Low on lubricant – fill to proper level.
• Improper type lubricant – replace with proper lubricant.
PROBLEM: TRACTOR STALLS
Possible Solutions:
• Auger is encountering rocks or roots or other foreign
object – remove object or change hole location.
• Tractor idle is not set correctly – tune tractor engine.
PROBLEM: AUGER BOLTS SHEAR ON GEARBOX
OUTPUT SHAFT
Possible Solutions:
• Shearbolt on input shaft has been replaced with a
harder bolt – replace with Grade 2 bolt as per instruc-
tions.
1. Heavy Duty Fishtail Center Point: Recommended
for tough or rocky soil conditions. The fishtail point will
work around smaller rocks. Order part #170802.
2. 12” Auger Extension: Available for situations where
deeper holes are required. NOTE: Smaller tractors
may not raise auger high enough to clear hole when
12” auger extension is used. Order part #170705.
3. Hydraulic Down Force Kit: For tough, hard soil con-
ditions. This will allow operator to put 300-400 lbs. of
down force on the auger to force cutting edges into
tough or hard ground. Tractor must have auxiliary
hydraulic outlet. Order part #170810 for Model 300
Post Hole Diggers.
4. Parking Stand Kit: This kit allows the post hole
digger to be stored in an upright position. Makes
connecting and disconnecting from tractor an easy
one man operation. Order part #102160.
