9.0 Coupling up
Before operational use, the tractor front ballast needs to be checked to ensure
there is sucient stability when coupled up the Grange 6m 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
6m LDT centre of gravity)
IF,min = (IRx(c+d))-(TFxb)+(0,2 xTExb)
a+b
Please refer to the denitions in the table under
section 9.0 which identies the variables which
are required to calculate the value (kg) for the
front ballast; IF min
Please refer to Appendix 1.0 at the rear of the
manual for example calculations.
The value IF min allows to have a load on the front
axle equivalent to 20% of the un-laden mass of
the tractor.

12.0 Getting started in the field
Note the requirements 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.
i. Stop the movement controls of the tractor, apply the handbrake, stop the engine
and remove the key.
ii. Remove the tight turn pin from the wing securing position and locate in the
temporary storage position on the frame (ref Fig 3.0).
If using the Grange 6m LDT independently, locate the pin in the temporary
storage position on the frame (ref Fig 3.0).
If using the machine in combination with a trailed implement and are requiring
the tight turn feature to be operated, position the pin in the tight turn position
on the frame (ref Fig 23.0)
iii. On the machine wings, turn the hydraulic hand valves through 90° which have
locked the folding wings in the transport position.
iv. Return to the tractor, start the engine and lower the rear three point linkage
hitch to position the rear attachment hitch of the Grange 6m LDT to resemble
the same height as the tractor drawbar. Refer to the tractor operator’s 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.
v. From the tractor cab position, apply the auxiliary hydraulics to lower the wings
into the working position.
vi. There are three disc rams which are located on each wing and one placed
centrally under the headstock. There are two main beam lift rams. The disc rams
rotate 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.
vii. Stop the movement controls of the tractor, apply the handbrake, stop the
engine and remove the key. Starting with the disc rams, apply a consistent
number of spacers to each of the three rams (ref gs 19.0 and 20.0). Following
on with the main beam lift rams; apply a consistent number of spacers to both
of the main beam lift rams as illustrated in gs 21.0 and 22.0. Each spacer
is colour coded to represent dierent thicknesses. For safe and ecient
operation of the Grange 6m LDT, the set of three disc rams and two main
beam rams must be operating to an even depth. The low disturbance legs can
cultivate to a maximum depth of 300mm.
viii. 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.
ix. In the event that adjustments need to be made in the eld for the Grange
6m 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 6m LDT.
