CompanyProle
Australia’s largest manufacturer and exporter
of Disc ploughs, Grizzly Engineering Pty
Ltd is an Australian owned and operated
manufacturing company based at Swan Hill in
Victoria.
Like many other Australian icons of ingenuity,
the Grizzly plough was founded on need.
The Grizzly name was established in the
early 1980’s by country people with the will to
construct a better o󰀨set disc plough.
In 1983, a unique three gang, tandem o󰀨set
disc design was patented and released. This
innovative Grizzly plough provided complete
ploughing out (no unworked ridges), less
working draught, elimination of side draught
and longer disc life. Other new features, at
that time, included self phasing wheel lift and
improved scrapers.
Grizzly’s broad range of versatile ploughs
suit a wide variety of agricultural applications.
Sizes vary from 1.4 metres to 15.6 metres
working width.
Grizzly also manufacture Bankers,
Renovators, and a large range of subsoil and
row crop Rippers from 1 tine.
Advantages of Grizzly technology include
lower power requirements, signicant fuel
savings, reduced stress on components,
reduced maintenance costs, and greater
operator control allowing e󰀨ortless
adjustments for better performance.
The Grizzly product has earned a reputation
of uncompromising strength, performance and
reliability.
Each model is designed with inbuilt durability,
and accuracy, E󰀩ciency and easy operation
for sustainable farming practices.
Continued investment into research and
development plays a key role in the success
of the company’s product range
The company has a very successful and
loyal dealer network throughout Australia.
All dealers are backed by Grizzly training,
technical support and rapid delivery parts
replacement anywhere in Australia.

3 The Right Machine
The Grizzly Deep Digger is a heavy duty, fuel
e󰀩cient, deep ripping machine for breaking
up sub-soil hard pans. It is also used for deep
cultivation applications and in conjunction with
Agricultural architects where land forming,
laser levelling and sub-soil ripping is required.
The action of the Deep Digger tine fractures
the structure of the sub-soil so that drainage,
root growth and the process of mineral
osmosis is enhanced. This leads to better
growth and higher crop yields in most
compacted soils. The Deep Digger is also
used to bring small stumps and roots, to
the surface, ie grape vines to prepare for
cultivation or laser levelling. All tasks or
applications are performed with minimal
disturbance to the soil surface.
The Deep Digger features parabolic tines
congured in a “V” formation for ease of
penetration, better traction and greater
implement strength. Tines are constructed
of 350 grade steel plate for excellent wear
resistance. A rounded edge spring steel
wear bar and replaceable point increase the
e󰀨ective action and life of the tine. All tines
are tted with shear pins to prevent damage
to the frame in rough conditions. Tines can
be individually locked up in a non-working
position for narrower working width or wider
tine spacing.
The Grizzly Deep Digger is available in either
linkage models ranging in size from one to
nine tines or We trust the Deep Digger will
play an important part in your farming program
for many years to come.

Specications are subject to change without prior noticationDecember 2019
yTake care when hitching to tractor,
never stand between tractor and
machine.
yNever leave the machine in a raised
position when not in use. Accidental
release of control levers or hydraulic
hose failure will cause implement to drop
down. This can cause serious injury or
death to someone near or under the
machine.
yDo not transport at speeds in excess
of 30 kph. Transporting at faster speeds
may result in loss of implement control
and serious damage or injury. Speed
must be reduced when travelling on
uneven ground or inclined terrain. Do not
transport a fully loaded commodity cart
on public roads.
yDo not transport with a vehicle with
a gross mass less than that of the
Machine. Use a tractor large enough to
maintain control. Latch brakes together.

ramp, the truck must have a deck widener to
do this.
1. The Deep Digger has 4 sling points as
indicated, check the specications in
section 8 for the total weight, ensure
crane, slings, etc. are capable of doing the
job before lifting.
Flat Packed
To assemble
1. Unpack the at pack. Using a crane,
unstack the at pack and place the
components in a convenient place on the
oor or ground. Use a plan view of the
machine shown in the operator’s manual
under Deep Digger frame assemblies
to familiarise yourself with location of
machine components.
2. Raise the frame, place it on support
stands and bolt the frame together.
3. Fit wheels to the main frame axles. Fit
wheels to the main frame axles and fully
tighten wheel nuts to 320ft/lb.
Grizzly Deep Diggers are designed
for agricultural usage only. They are
not suitable for land clearing (stump
mining) operations or tillage at high
speed.
If damage occurs from clearing or
tillage at high speed.
IMPORTANT!
4. Assemble the hitch pull onto the main
frame:
• a) Align the main pull frame and t the two
pins.
• b) Fit the pitch control ram using the pins
provided.
5. Assemble all hydraulic hoses onto the
Deep Digger. There are three circuits on
the trailed Deep Digger models - pitch
control ram, wheel lift and an optional
crumble roller. All hoses and tubes are
custom made and numbered.

WARNING!
Always stay out from underneath a
Deep Digger unless it is resting mly
on the ground or supported with
appropriate stands or blocks when
raised. Failure of hydraulic systems
or jacks can cause the Deep Digger
to drop, pinning or crushing personnel
and causing serious injury.

Wheel Lift control circuit
When tting the lift control circuit, rst t 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 tted 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, t 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.

9:3 Pull Height
The Deep Digger pull features hydraulic pitch
control for precision operation. However the
pull and the pitch control mechanism must be
set up to work in the optimum position so that
full adjustment is available to the operator.
When the ripper is working at the required
depth, the optimum position of the pull is
sloping up towards the tractor.
There is an adjustment available to achieve
this.
9 Assembly Instructions
9:4 Pull Tongue Height
It may be necessary to move the tongue up
or down to achieve a level pull. To set the
correct working position of the pull, follow the
instructions below:
1. Choose a level site for the ripper and
tractor for adjusting the pull tongue.
2. Lower the ripper so that the tynes are
resting on the ground, and the wheels are
resting on the ground.
3. Disconnect the pull from the tractor, using
the Pitch control hydraulics raise the
pull to clear the tractor, move the tractor
forward so that the tractor drawbar clears
the pull. Raise / lower the pull so that is is
sloping slightly down towards the tractor.
4. 4 Remove the pull tongue and replace at
the height of the tractor draw bar tighten
the bolts to 274 ft/lbs
5. 5 Reconnect the tractor.
6. Test at working depth the pull should be
sloping up towards the tractor.
Whenever a different tractor is used
with the Deep Digger, it is absolutely
essential to check the pull height
is correctly adjusted. Failure to
adjust the pull height correctly may
adversely affect ripping performance.
The initial setting up of your ripper
behind a tractor is critical to its
correct performance.
IMPORTANT!
Pull Tongue adjustment
Always use a torque wrench on wheel nuts and
gang bolts, over-tightening will damage threads.
