OPERATION
3. TRACTOR REQUIREMENTS
In addition to tractor horsepower and size required to operate the boom unit, the tractor must also be properly
equipped to provide operator protection, to alert approaching vehicle drivers of the tractor’s presence, and to
ensure tractor stability when mowing with the boom fully extended.
Tractor Requirements and Capabilities
• ASABE approved Roll-Over Protective Structure (ROPS) or ROPS cab and seat belt.
• Tractor Safety Devices .................... Slow Moving Vehicle (SMV) emblem, lighting
• Tractor Ballast .................................20% Minimum of total tractor weight on frot end of tractor.
• Power Take Off.................................540 RPM
3.3 Tractor Horsepower
The horsepower required to operate the mower depends on many factors including vegetation to be cut, terrain
condition, operator experience and condition of the mower and tractor. For most mowing conditions, the side
rotary works best on a tractor with at least 90 HP. Operating the mower with a tractor that does not have
adequate power may damage the tractor engine.
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.
(SG-7)
3.2 Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of
the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor
warning signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or implement. OPS-U- 0004_A
