9.0 Coupling up
Before operational use, the tractor front ballast needs to be checked to ensure
there is sucient stability when coupled up the Grange 3m LDT and any 2nd stage
cultivation/seeding equipment. The diagram and example calculation in Fig 4.0
demonstrates the values which need to be established. Note the value d [m] is taken
from the centre of the linkage balls to the centre of the lifting eyes (e.g. the Grange
3m LDT centre of gravity)
Please refer to the denitions in the table in section
9.0 which identies the variables which are required
to calculate the value (kg) for the front ballast; IF min
The value IF min allows to have a load on the front
axle equivalent to 20% of the un-laden mass of
the tractor.
Please refer to Appendix 1.0 at the rear of the manual
for example calculations.

FIG 5.0 CORRECT LINKAGE CONFIGURATION IN WORKING POSITION
10.0 Setting up machine for work
When setting up the tractor for connection to the Grange 3m LDT, rstly adjust the
lower link check chains to reduce the lateral sway as much as possible (ideally less
than 20mm). Ensure that the linkage balls are not corroded and can turn on the pins.
The correct top link setting is important to ensure the Grange 3m LDT is safe and
ecient in operation, ref Fig 5.0. Fig 6.0 shows a correctly congured Grange 3m LDT
coupled up to 2nd stage cultivation / seeding equipment via the link arm hitch.
The lower link arms should remain locked in position during all work and transport
mode operations. Minimal adjustment of the link arms can provide additional
clearance over obstacles. Activate the auxiliary hydraulics to raise the cutting discs
and legs to their top position to clear any surface obstacles. This setting then
provides a consistent coupling height for 2nd stage cultivation/seeding equipment
connected to the clevis hitch.

When connecting 2nd stage cultivation/seeding equipment; activate the
tractor auxiliary hydraulics to lift the Grange 3m LDT main beam and
cutting discs to the top of their travel. This provides suitable clearance
to lower the main frame on the tractors three point linkage to couple
up with the Grange 3m LDT with the 2nd stage cultivation/seeding
equipment using either clevis or link arm attachment.
Ensure that the 2nd stage cultivation/seeding equipment is safely
attached the rear of the Grange 3m LDT along with hydraulic and
electrical connections.
10.1 Clevis hitch
The mass of the rear clevis hitch on the Grange 3m LDT equipment
has a mass of 45kg. Therefore the safe working procedure is to put
the coupling pin through the clevis hitch and secure in place, with a
washer and nut and bolt. Use a workshop crane or other approved
lifting systems to take the weight before removing the locating pin.
Readjust and relocate securing pin with the appropriate lynch pin
before releasing from the lifting equipment. Fig 7.0 and 8.0 illustrates
the component and securing method.
TOWING PIN AND ALSO USED FOR
ATTACHING THE LIFTING EQUIPMENT
Connect the hydraulic couplings to the tractor double acting services.
Be-aware of the hazards associated with hydraulic hoses under pressure. FIG 10.0 LINK ARM HITCH REMOVED FROM
REAR OF GRANGE 3M LDT
10.2 link arm hitch
The mass of the rear link arm hitch has a mass of approximately 100kg.
Removal of the rear link arm hitch will require the use of mechanical
handling equipment with adequate lift capacity and counterbalance,
with the use of compliant strops or chains and lifting hook. Fig 9.0

11.1 Road Vehicles (Construction
and Use) Regulations 1986
The legislation which covers the transportation of the Grange 3m LDT
equipment on the UK public highway when coupled to the tractor
is The Construction and Road Use Regulations (C&U) 1986. The
requirements to apply are as follows;
i) Check the dimensions (width and length) and mass (kg) of and 2nd
stage cultivation/seeding equipment which are coupled to the
Grange 3m LDT equipment.
The maximum permitted masses and vehicle dimensions for
transporting the Grange 3m LDT and associated 2nd stage
cultivation/seeding equipment is as follows (Not including
the tractor);
i) The maximum permitted mass of a trailed implement is
14,230kg. The operator’s manual for the 2nd stage cultivation/
seeding equipment must be checked to verify its mass, including
any restrictions on transportation on the public highway with
material in a seed hopper.
ii) A maximum width of 2.55m
iii) A maximum length of 15m.
The speed limit and required notication to the authorities
are as follows;
i) If the overhang of the Grange 3m LDT equipment in the transport
position exceeds 305mm from the widest point of the tractor wheel
/ tyre setting, a width marker board is required.
ii) As the transport width of the 3.0m LDT equipment is between
3.0m and 3.5m with or without any 2nd stage cultivation / seeding
equipment coupled up, the maximum speed limit of the tractor and
the Grange 3m LDT equipment is 20mph. If the planned journey
exceeds 5 miles, or the speed limit on any of the public highway is
40mph or less, the operator must notify the Police in advance of
the journey.
12.0 Getting started in the field
Note the requirement for the use of appropriate PPE (gloves, overalls and safety
boots) as components such as cutting discs have sharp edges.
Once arriving in the eld, the machine must be set-up correctly for the cultivation
routines. Stop the movement controls of the tractor, apply the handbrake,
stop the engine
i) Using the tractor hydraulics lower the three point linkage to position the rear
attachment of the hitch of the Grange 3m LDT to resemble the same height
as the tractor drawbar. Refer to the tractors operators’ manual for the safe
operation of externally mounted hydraulic controls. Please note the three
point linkage of the tractor now needs to be locked in position. The
Grange 3m LDT is now setup in the working position, ref g 11.0. Stop the
movement controls of the tractor, apply the handbrake, stop the engine and
remove the key.
ii) There is one disc ram located centrally under the headstock. There are two
main beam lift rams. The disc ram rotates the cutting discs out of work,
whereas the main beam rams elevate the low disturbance legs out of the
ground eliminating the need to raise the tractor three point linkage on the
headland turns.
iii) Assess the soil conditions and starting with the single disc ram apply the
required number of spacers, ref g 12.0. Following on with the main beam lift
rams; apply a consistent number of spacers to each ram as illustrated in g
13.0. Each spacer is colour coded to represent dierent thicknesses. For safe
and ecient operation of the Grange 3m LDT, the two main beam rams must
be operating to an even depth. The low disturbance legs can cultivate to a
depth of 300mm.
iv) When commencing work the cutting discs need to enter the ground between
50mm and 75mm.
v) Return to the tractor, restart the engine and activate the tractor auxiliary
hydraulics to engage the discs and lower the main beam to the ground whilst
engaging a slow forward speed.
vi) In the event that adjustments need to be made in the eld for the Grange
3m LDT working depth, apply the following procedure; Firstly raise the main
beam fully and rotate the discs out of work. Stop the movement controls
of the tractor, apply the handbrake, stop the engine and remove the key.
The adjustment of the spacers can be performed safely with the operator
positioning themselves at the front of the Grange 3m LDT.
11.0 Transport safety
Before undertaking transport of the Grange 3m LDT equipment
on the public highway refer to the details in section 11.1 with
regards to road legislation.
Please refer to section 9.0 for the correct tractor front counterbalance
when connecting 2nd stage cultivation / seeding equipment.

13.1 Replacing shear bolts
FIG 15.0 SHEAR BOLT WITH SHEAR PLANE
RED LINE – LOWER LEG (15MM)
YELLOW LINE – UPPER LEG (20MM)
FIG 16.0 SHEAR BOLT LOCATION
When replacing the points use suitable solid level
ground e.g. concrete/tarmac, to avoid the risk of
sinking and potential injuries whilst changing the
points as well as potential damage to tungsten
tipped points. The implement must be raised on the
tractor linkage and the tractor engine turned o and
handbrake applied.
It is important to support the weight of the Grange
3m LDT with appropriate axle stands to enable safe
access to the points. Please be aware it is forbidden
to work under a suspended load without the
adequate support.
Wear appropriate PPE which is safety glasses and
gloves. In addition the use of a safety bump cap will
prevent any inadvertent contact by your head with
the frame.
Once you are condent that you have met the safety
standards required you can proceed.
Unbolt the single xing (M10 x 40mm long bolt) from
the worn point to free the point. A new point can
then be replaced into the same position using the
same size xing. Ensure the bolt is fully tightened,
ref Fig 17.0.
When you have nished replacing the points,
remove the axle stands supports/chocks in order
to proceed.

Appendix 1.0: Example calculations: Ref Fig 4.0
IR
Please note these are indicative calculations
using industry examples for typical 200hp
tractor specications. Due to the combination
of the Grange 3m LDT and 2nd stage cultivation/
seeding equipment the tractor machine
combination can become unstable. The following
expression can be applied for the calculation
of the minimum ballasting at the front (IF
min) which allows to have a load on the front
axle equal to 20% of the unladen mass of the
tractor. The operator of the Grange 3m LDT and
and coupled 2nd stage cultivation / seeding
equipment must input the relevant values for
the tractor and 2nd stage cultivation / seeding
equipment they are using. In addition variables
such as tractor tyre pressures also need to be
checked and set to suit operational conditions.
Key Denition Values inputted
TE [kg] Mass of un-laden tractor 7300Kg
TF [kg] Front axle load of un-laden tractor 2701Kg
TR [kg] Rear axle load of un-laden tractor 4599Kg
