WARNING!
Always stay out from underneath a
Deep Digger unless it is resting fimly
on the ground or supported with
appropriate stands or blocks when

or jacks can cause the Deep Digger
to drop, pinning or crushing personnel
and causing serious injury.

9 Assembly Instructions
Wheel Lift control circuit
When fitting the lift control circuit, first fit the
feed hose to the bottom end of the master
cylinder located on the RHS of the machine.
Then connect the hose from the top of the
master cylinder to the bottom of the slave
cylinder on the LHS.
Finally, connect the tractor return hose into
the top of the slave cylinder on the LHS of
the machine. For phasing procedure, see the
operating instructions in the next section.
When all hoses and tubes are fitted to all the
circuits:
a) Fit shell clamps supplied.
b) Use zip ties every 300mm to tie hoses
together to keep hoses neat, tight and tidy.
c) Fit shrink wrap hose indicators near the
tractor end of the hoses when the unit is fully
plumbed.
Colour codes are:
Blue - Pitch Control circuit
Red - Lift Control circuit
Green - Crumble Roller circuit
6. Fit the tines.
7. Using a suitable lifting device (front end
loader, crane or forklift), the tine should
be positioned over the frame and then
lowered through the tine locating plates.
A small chain can be attached to the top
hook of the tine to assist lowering the tine
through the locating plates.
8.
Align the front pivot hole, fit and tighten
the pivot bolt so the plate just touches the
tine.
9. Align the rear shear pin catch of the tine
with the holes in the frame assembly. Fit
the shear pin and lock the pin into position
with the clips provided.
a) Fully extend lift control cylinders and
allow cylinders to fully phase by holding the
hydraulic lever open for about three minutes
after all cylinders are fully extended.
b) Operate the pitch control cylinder 2 or 3
times to ensure seals bed-in and all air is bled
from the circuit.
The unit is now ready to set up for operation.
10. Connect the Deep Digger to the tractor
drawbar and connect all hydraulic hoses.
Connect the hoses of both hydraulic
circuits to the tractor.
11. Operate and phase hydraulic circuits.
Operate both hydraulic circuits to test.
