HD25 and HD35 Hydraulic Post Hole Diggers 317-076M
Refer to Figure 1-8:
1.
Remove tractor top center 3-point link (not shown).
Keep hitch pin and retaining pin for future use.
2.
Ensure lower 3-point lift arms are stabilized to
prevent excessive side movement.
3.
Slowly back tractor to the Post Hole Digger while
using 3-point hydraulic control to align hitch holes in
lower 3-point lift arms with hitch pins on yoke.
4.
Set tractor transmission in park or engage tractor
park brake, shut tractor engine off, and remove
switch key before dismounting tractor.
5.
Slide lower lift arm hitch holes onto yoke hitch pins.
6.
Secure lower 3-point lift arms to yoke hitch pins by
inserting customer supplied linchpins through hitch
pins holes and rotating linchpin snap rings down.
7.
Connect center 3-point hitch hole in boom to tractor
center 3-point hitch holes using customer supplied
clevis pin and linchpin.
8.
Attach hydraulic hoses to tractor duplex outlet. Refer
to
“Hydraulic Hook-Up to Tractor”
on page 16 for
detailed instructions.
9.
Using tractor lift control lever, lift Post Hole Digger up
until auger is off the ground 1 to 2 inches.
10. With tractor set at an idle, engage hydraulics to view
auger rotation. The auger should rotate clockwise
when looking down from above. If auger rotates
counterclockwise, switch couplers at the duplex out
as follows:
a. Disengage hydraulics, set tractor in park or set
park brake, lower Post Hole Digger until auger is
resting on the ground, shut tractor engine off, and
remove switch key before dismounting tractor.
b. Switch quick release couplers at the duplex outlet
on the tractor.
c. Return to the tractor and repeat steps 9-10 to
verify auger is rotating properly.
Unhooking 3-Point Mount
Refer to Figure 1-8:
1.
Park tractor and Post Hole Digger on a flat, solid
surface.
2.
If available, use Land Pride’s storage stand to unhook
and store the Post Hole Digger. Refer to
on page 29 for detailed unhooking
instructions. Continue with step 3 below if storage
stand is not available.
3.
Lower Post Hole Digger down. Make sure Post Hole
Digger is secured with post and bracing so that it
cannot twist and/or fall while unhooking the unit.
4.
Disconnect hydraulic hoses and wrap them around
the boom to keep fittings out of the dirt.
5.
Pull lower 3-point linchpins and pull arms off the yoke
hitch pins. Keep linchpins for reuse.
6.
Remove center 3-point hitch pin and lower Post Hole
Digger yoke and boom down onto the ground or
support blocks. Keep hitch pin and retaining pin for
reuse.
7.
Once post hole digger is disconnected and tractor’s
3-point arms are clear of the digger, drive tractor
away being careful not to catch on the Post Hole
Digger and supports.
NOTE:
It is easier to unhook and hook-up to the
Post Hole Digger if it is supported upright. Land
Pride offers an accessory storage stand to aid in
storing, unhooking and hooking-up to the unit. See
