prime mover as it has a power out-
let source which is also called Pow-
er Take or PTO shaft.

revolution is reduced by the level
gears to drive the front wheel. The
4WD mechanism with level gears
provides wider steering and greater
durability.

5. ROPS (ROLL OvER PROTECTIvE STRUCTURES)
RK Tractors are equipped with a
frame for the protection of opera-
tors.
In the case of cab tractors the frame
is incorporated in the cab structure.
The objective of the frame or cab
structure is to protect the operator
in the event of a roll over and they
are designed to support the entire
weight of the tractor in that event.
Each RK ROPS frame or cab struc-
ture is designed and has been test-
ed to meet industry and or Govern-
ment standards.
Included in these tests were all
mounting bases and bolts or other
fasteners.
As the ROPS frame or cab togeth-
er with the seat belt was designed to
meet certain standards, they must be
maintained in good order and condi-
tion.
To achieve this objective, both the
structure and the seat belt should be
inspected on a regular basis (every
time the tractor is serviced)
In the event that the seat belt is dam-
aged or frayed, it should be replaced
and in the event that the ROPS
frame or any part of the mounting
structure is damaged or cracked, the
faulty component must be replaced
with a new unit.
Such a unit must meet all of the test
criteria of the original unit.
Fitment of an inferior item or items
affects the certification of the entire
ROPS structure and the effective-
ness of the structure in the event of
an accident. Drilling or welding of the
ROPS structure is forbidden.
ROLL OvER PROTECTIvE STRUCTURES (ROPS)►USE OF THE TRACTOR WITH
THE ROPS LOWERED CAN
CAUSE FATAL INjURIES
►
On some models the ROPS frame
has a fold down feature, which can
be used to enter low buildings etc.
Take care when lowering the upper
section of the ROPS frame and take
extreme care while driving the tractor
with the ROPS frame lowered.
Do not wear the seat belt with
the ROPS lowered and please
remember that the fold down facility
is for special circumstances only and
must not be lowered for general use.
For ROPS frames to be effec-
tive and protect the operator,
the seat belt provided must
be worn in order to keep
operators within the ROPS
protected area in the event of
a roll over. Failure to use the
seat belt can still cause seri-
ous injury or death.

GENERAL INFORMATION
R24O003A
If the tractor has rolled over or the
ROPS has damaged (such as strik-
ing an overhead object during trans-
port), It must be replaced to provide
the original protection. After an ac-
cident, check for damages to the 1.
ROPS 2. Seat 3. Seat belt & seat
mountings. Before you operate a
Tractor, replace all damaged parts.
DAMAGE OF THE ROPS►

If the ROPS is removed or re-
placed, make certain that the
proper hardware is used to re-
place the ROPS and the rec-
ommended torque values are
applied to the attaching bolts
WARNING
WARNING

Always wear your seat belt if
the tractor is equipped with
ROPS.
WARNING

Never attach chains, ropes to
the ROPS for pulling purpos-
es; this will cause the Trac-
tor to tip backwards. Always
pull from the Tractor draw-
bar. Be careful when driving
through door opening or under
low overhead objects. Make
sure there is sufficient over-
head clearance for the ROPS
to avoid fatal injuries.
DO NOT WELD, DRILL OR
STRAIGHTEN THE ROPS

PROTECTION CHILDREN►
T45O204A
Keep children and others away from
the tractor while operating.
BEFORE YOU REVERSE:

Look behind tractor for children.

Do not let children to ride on trac-
tor or any implement.
USE OF ROPS AND SEAT BELT►
T45O205A
The Roll Over Protective Struc-
ture (ROPS) has been certified to
industry and/or government stan-
dards. Any damage or alternation
to the ROPS, mounting hard-ware,
or seat belt voids the certification
and will reduce or eliminate protec-
tion for the operator in the event of
a roll-over. The ROPS, mounting
hardware, and seat belt should be
checked after the rst 100 hours of
tractor and every 500 hours there-
after for any evidence of damage,
wear or cracks. In the event of dam-
age or alteration, the ROPS must be
replaced prior to further operation of
the tractor.
The seat belt must be worn during
machine operation when the ma-
chine is equipped with a certified
ROPS.
Failure to do so will reduce or elim-
inate protection for the operator in
the event of a roll over.
