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 1660
boom mower requires a tractor with at least 60 HP PTO. Operating the mower with a tractor that does not have
adequate power may damage the tractor engine.
3.7 3-Point Hitch
1660 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.

Width from outside to outside A-frame.........32-3/8”

3.8 Hydraulics
The 1660 is available with a Totally Independent Hydraulic System complete with Rotor Rotation Control. The
rotor can be started, stopped, or reversed by operating a lever on the Control Console.
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. Never operate the tractor PTO
with the PTO master shield missing or in the raised position.
