(ROPS) Roll Over Protective Structures
Roll Over Protective Structures (ROPS)
TYM Tractors are equipped with a frame for the protection of operators.
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 TYM ROPS frame or cab structure is designed and has been tested to meet industry and or
Government standards.
Included in these tests were all mounting bases and bolts or other fasteners.
DANGER
For ROPS frames to be effective 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 serious injury or death.
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
9
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.
Use of the tractor with the ROPS lowered can cause fatal injuries.
As the ROPS frame or cab together with the seat belt was designed to meet certain standards,
they must be maintained in good order and condition.
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 damaged 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
effectiveness of the structure in the event of an accident.
Drilling or welding of the ROPS structure is forbidden.

Damage of the ROPS
If the tractor has rolled over or the ROPS has damaged (such as striking an overhead object during
transport), It must be replaced to provide the original protection. After an accident, check for damages
to the 1.ROPS.2.Seat 3.seat belt & seat mountings. Before you operate a Tractor, replace all damaged
parts.
10
DO NOT WELD, DRILL OR STRAIGHTEN THE ROPS
Warning
Never attach chains, ropes to the ROPS for pulling purposes; this will
cause the Tractor to tip backwards. Always pull from the Tractor drawbar.
Be careful when driving through door opening or under low overhead
objects. Make sure there is sufficient overhead clearance for the ROPS
fatal injuries
Warning
If the ROPS is removed or replaced, make certain that the proper hardware
is used to replace the ROPS and the recommended torque values are
applied to the attaching bolts
Warning
Always wear your seat belt if the tractor is equipped with ROPS

NOTE: Do not use solvents to clean the seat. Use warm water with a little detergent added.
Before operating a Tractor it is important to adjust the seat to the most comfortable position & check
whether it is properly locked in its position. Figure 1 identifies the seat fitted to your Tractor.
FOR Sliding seat
To select Seat position, move Adjusting lever and slide Seat closer to or away from Dash panel and

USE OF ROPS AND SEAT BELT
The Roll Over Protective Structure(ROPS) has been certified to
industry and/or government standards. Any damage or alternation to
the ROPS, mounting hard-ware, or seat belt voids the certification
and will reduce or eliminate protection for the operator in the event
of a roll-over. The ROPS, mounting hardware, and seat belt should
be checked after the first 100 hours of Tractor and every 500 hours
thereafter for any evidence of damage, wear or cracks. In the event
of damage 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
machine is equipped with a certified ROPS.
Failure to do so will reduce or eliminate protection for the operator
in the event of a roll over.
PRECAUTION TO AVOID TIPPING
Do not drive where the Tractor could slip or tip.
Stay alert for holes and rocks in the terrain, and other hidden
hazards.
