5. OPERATION
This digger is designed for use only on tractors with a 540-RPM power takes off. The auger is
designed to operate just above idle speed. Clear the work area of objects that might be picked up
and thrown or entangled in the auger such as vines, tree limbs, wire, etc.
The auger is of the pendulum swinging type and should hang in a vertical position when
raised clear of the ground. On the ETA 6900 and ETA Compact there is an
Optional
directing
rod (#15) attached to the gearbox to control the swing of the gearbox. It can be moved in or out
by loosening the setscrew on the side of the gearbox. This allows the tractor operator, from his
seat to straighten the angle of the auger to dig a straight hole. Due to the design of the ETA
6900-HD gearboxes, the directing rod is not required. To prevent possible instantaneous
driveline failure, never move digger from hole to hole or transport it while auger is rotating. This
could lead to injury from flying pieces of the failed driveline. With auger raised clear of ground
drive into position and engage PTO with tractor idling; lower digger slowly and permit it to dig
one foot (1ft.) deep. Raise digger and allow auger to clear itself by operating PTO, lower digger
and dig another foot deep. Repeat this until hole is to desired depth. To prevent entanglement and
possible serious injury or death all persons except for the operator seated on the tractor, should
maintain a minimum safe distance of twenty five (25’) feet from the auger at all times. In loose
and sandy soil, you get a cleaner hole by stopping rotation of the auger before lifting it from the
hole and starting it just before it clears the hole to throw the soil on the auger out and away from
the hole. DO NOT SHOVEL dirt away from a rotating auger as the shovel can be caught and
thrown by the auger causing serious personal injury. In wet clay, be very careful not to let the
auger go too deep as it may get stuck If the auger is stuck either in wet clay, roots, or stones,
DISENGAGE PTO, shut off tractor engine and use large wrench on auger and reverse rotation of
the digger. One complete turn of the auger will usually free the auger. Then gently lift the auger
with the tractor lift. If it is not free, continue reversing procedure until it can be lifted clear.
Do not operate digger on steep hillsides. When digging on uneven or hilly terrain, position the
tractor with the posthole digger uphill. If the posthole digger is pointed downhill, the tractor
could tip over when attempting to pull the auger from its hole.
!!!!WORK SAFELY-FOLLOW THESE RULES!!!!
6. DAILY CHECK LIST
- Check that digger is properly and securely attached to tractor.
- During inspection, check that all nuts and bolts are secure.
- Check conditions of auger Cutting edges and security of attachment.
- Check that all safety shields are in place.
7. MAINTENANCE
*keep tractor and digger in good operating condition and all safety devices in
place.
*Periodically tighten all bolts, nuts and screws to ensure digger is in a safe
condition to operate.
*The shear bolt is where the PTO (power take off) shaft yoke fits to the gearbox
