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: GEARBOX OVERHEATING
Possible Solutions:
•Low on lubricant – fill to proper level.
•Improper type lubricant – replace with proper lubricant.
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.
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: 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.
POST HOLE DIGGER OPTIONS
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
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.
