ASSEMBLY, OPERATION, & MAINTENANCE INSTRUCTIONS
•
PTO assembly “bottoms out,” not allowing
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 tractor dealer.
•
Soil could have hardpan layer 6”-10” below
surface - use optional fishtail.
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 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(s) 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.
PROBLEM: AUGER SCREWS ITSELF INTO
THE GROUND
Possible Solutions:
•
Operator did
NOT
ease 3-Point hitch to
ground slowly.
•
Faulty 3-Point hitch hydraulic system on
tractor.
•
Draft control is not in OFF position.
•
Tractor is too small to handle digger.
PROBLEM: PTO DRIVELINE ASSEMBLY
COMES OFF INPUT SHAFT OF GEARBOX
WHEN SHEAR BOLT IS SHEARED.
Possible Solutions:
THIS IS A DANGEROUS SAFETY HAZARD,
CORRECT IMMEDIATELY!
•
Roll pin missing in yoke at gearbox input
shaft. Install roll pin as per instructions.
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 shear bolt – 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.
