3.5 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.

3.6 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 condition, the 1600
boom mower requires a tractor with at least 60 HP. Operating the mower with a tractor that does not have
adequate power may damage the tractor engine.

3.7 3-Point Hitch

RMB 1865 boom mowers can attach to tractors
with a CAT II hitch. Refer to the tractor operator's
manual for the category of the tractor used. If the
hitch does not conform to ASABE Cat II
dimensions, the mower may not fit or raise
properly. Consult an authorized dealer for possible
modification procedures to mount nonconforming
hitches.
Use the correct hitch pins for the hitch category
being used. For Cat II hitches it requires 1-1/8"
lower and 1" upper diameter hitch pins.
