OPERATION
3.4 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 PT5
sickle bar requires a tractor with at least 15 HP. Operating the mower with a tractor that does not have
adequate power may damage the tractor engine.
3.5 3-Point Hitch
PT5 sickle bar can attach to tractors with a CAT I
three-point hitch. Refer to the tractor operator’s
manual for the category of the tractor used. If the
hitch does not conform to ASABE Cat I or 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 a Cat I hitch, 7/8” lower and 3/4”
upper diameter hitch pins are used.

ground or from overhead trimming. Stop mowing if workers or passersby
are within 300 feet.

3.3 Tractor Lighting and SMV Emblem
If the tractor will be operated near or traveled on a
public roadway it must be equipped with proper
warning lighting and a Slow Moving Vehicle (SMV)
emblem which are clearly visible from the rear of
the unit. Most tractor’s have different settings for
operating and transporting lighting. Refer to the
tractor operator’s manual for using the tractor’s
light switch and operating the turn signals.
