3.2 Tractor Horsepower

The power required to operate a blade is determined by the tractor PTO horsepower. For most operating
conditions, the 300 Series rear blade requires a tractor with at least 300 HP for 12’ and 250 HP for 14.’
Operating the blade with a tractor that does not have adequate power may damage the tractor engine.
Exceeding the recommended horsepower may cause blade damage by overpowering the unit in heavy
operating conditions.

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 model 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. (SG-7)
