3.1 ROPS and Seat Belt
The tractor must be equipped with a Roll-Over-Protective-Structure (ROPS) (tractor cab or roll-bar) and seat
belt to protect the operator from falling off the tractor, especially during a roll over where the driver could be
crushed and killed. Only operate the tractor with the ROPS in the raised position and seat belt fastened.
Tractor models not equipped with a ROPS and seat belt should have these life saving features installed by an
authorized dealer. OPS-U- 0003
Operate this Equipment only with a Tractor equipped with an approved roll-
over-protective system (ROPS). Always wear seat belts. Serious injury or even
death could result from falling off the tractor, particularly during a turnover when
the operator could be pinned under the ROPS.
3.2 Tractor Horsepower
The power required to operate these implements is determined by the tractor PTO horsepower. For most
operating conditions, the Road Graders require a tractor with the maximum of 72 PTO HP- 4 wheel drive and
90 PTO HP for 2 wheel drive. Operating these implements with a tractor that does not have adequate power
may damage the tractor engine. Exceeding the recommended horsepower may cause road grader damage by
overpowering the unit in heavy operating conditions.
