This operator’s manual is for retention with the
machine during all times of operation. If the
machine is to be sold onto other users, please
provide the manual as part of the transaction.
In the event that the manual becomes damaged
beyond eective use, please contact the
manufacturer for updated copies, stating the
machine specication and serial number.
The contents of this operator manual are correct
at the time of print but may be subject to additions
and change at any time in the future.
This manual refers to the following Grange Machinery
Ltd equipment;
1.0 Identification of manual
MACHINE TYPE WORKING WIDTH SERIAL NO’S
6m LDT 6m
The serial plate is located on the headstock of the Grange 6m LDT, as detailed in the photo below.
SERIAL PLATE LOCATION
The Grange 6m LDT is designed for primary
cultivation practices where soil pans need to be
removed to allow root penetration and water
inltration. The discs cut through any surface
trash and allow the legs to alleviate the subsurface
compaction with minimal disturbance to the top soil
and reducing moisture loss.
The Grange 6m LDT incorporates both a lower
linkage arm assembly and a clevis hitch on the
rear to allow secondary cultivation or seed drill
equipment to be attached. Hence providing the
solution for one pass seed establishment.
1.1 Introduction to the Grange 6m LDT
1.2 Meanings and definitions
Throughout the manual various denitions are used.
Their meanings are referred to here;
REFERENCE TERM MEANING
2nd stage cultivation / seeding
equipment
Cultivation or seeding equipment coupled to the Grange 6m LDT
machine via the clevis hitch or 2 point linkage.
Ballast Additional weights or other equipment to ensure tractor stability
when the Grange 6m LDT equipment is in operation.
Qualied and experienced
A person (operator) who has received appropriate instruction
and where necessary undertaken a qualication for operating the
relevant machinery. The operator understands the health and safety
procedures for use of the Grange 6m LDT.

1.3: Declaration of Conformity
The Grange 6m LDT is designed to high quality
engineering principles. However there are potential
hazards which the operator must be aware of during
use. The owner of the Grange 6m LDT equipment
is responsible for ensuring that all operators
familiarise themselves with the contents of the
manual before use.
Non-compliance with safety instructions can lead
to warranty claims becoming invalid. Grange
Machinery Ltd shall not be responsible for any
damage caused by the use of spare parts or
accessories and ancillary equipment not supplied or
approved by Grange Machinery Ltd
2.0 Safety considerations during the machines life cycle
3.0 Check your own working systems!
i. Ensure only qualied and experienced tractor operators are given permission to
use the Grange 6m LDT.
ii. Ensure the operator has the correct Personal Protective Equipment (PPE) when
working with the Grange 6m LDT. The recommendation is safety boots, close
tting coveralls and wear required work gloves.
iii. Does the operator understand the principles of operation for the Grange 6m
LDT? For example, the 3 point linkage settings, depth control and replacement
parts such as shear bolts and points.
iv. Is the operator aware of the safe equipment conguration for the Grange 6m
LDT and 2nd stage cultivation/seeding systems when coupled to the tractor on
the public highway? Refer to section 11.0 in this manual.
v. Can the operator seek advice on operational parameters for the Grange 6m LDT
equipment from other persons when working remotely in the eld?
vi. When performing any adjustments to the Grange 6m LDT and any 2nd stage
cultivation/seeding equipment, the tractor engine must be turned o, the key
removed and handbrake applied to prevent the hydraulics from operating.
