TROUBLE-SHOOTING GUIDE
(continued)
PROBLEM: HYDRAULIC HOSE FAILURE
Possible Solutions:
• Hydraulic relief pressure setting is very high and may
cause hydraulic hose failure.
• Hoses are worn or frayed – replace hose.
• Hose rating may be too low for hydraulic system
pressure. Replace with higher rated hoses.
• Hose being pinched – reroute hose and refasten.
PROBLEM: AUGER VEERS OFF AT AN ANGLE
WHILE DIGGING.
Possible Solutions:
• Auger may have encountered a rock or large root. Hole
may have to be relocated.
• Post hole digger mount may not be properly latched on
tractor or skid steer loader. Check lock pins.
• Operator has moved slightly while digging hole. Always
set brakes and use extra care on slopes.
• Operator applied excessive down pressure with loader
causing front of power unit to raise off ground and then
shifted sideways
PROBLEM: GEARBOX FAILURE
Possible Solutions:
• No oil in gearbox.
• Oil not changed per instructions.
• Bent output shaft is due to operator moving power
unit when auger is in hole.
PROBLEM: AUGER ROTATES TOO SLOW
Possible Solutions:
• Hydraulic system on power unit too small for hydraulic
post hole digger model being used.
• Hydraulic system may not be delivering its rated
volume of oil due to wear. Hydraulic pump may need to
be repaired.
PROBLEM: AUGER ROTATES TOO FAST
Possible Solutions:
• Hydraulic system of tractor or skid steer too large for
hydraulic post hole digger unit. Use slower engine
speed.
PROBLEM: GEARBOX OVERHEATING
Possible Solutions:
• Low on lubricant – fill to proper level.
• Improper type lubricant – replace with proper lubricant.
PROBLEM: AUGER STALLS
Possible Solutions:
• Auger is encountering rocks or roots or other foreign
object – remove object or change hole location.
• Hydraulic system may not be supplying rated pressure
(usually 1500 to 2250 PSI). Consult your dealer.
PROBLEM: AUGER BOLTS SHEAR ON GEARBOX
OUTPUT SHAFT
Possible Solutions:
• Auger is encountering rocks, roots or other obstruction.
• Bolts were not tightened properly.
• Operator is rapidly reversing hydraulic control valve –
putting excessive shock loads on bolts.
PROBLEM: 3 PT. POST HOLE DIGGER WON’T LIFT
HIGH ENOUGH
Possible Solution:
• 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.
