OPERATION
2.3 Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the SE8A lift mower requires a tractor with at least 45 HP, the semi-mount requires 40 HP, and the
pull type mower requires at least 30 HP. Operating the mower with a tractor that does not have adequate
power may damage the tractor engine. Exceeding 90 HP may cause mower damage by overpowering the unit
in heavy cutting conditions.
2.4 3-Point Hitch
Lift Type Mower-The tractor 3-point hitch must be
rated to lift at least 1300 lbs. This unit supplied
standard with CAT II pins.
The Lift and Semi-Mount Type mower is designed
to be mounted on tractors with either a CAT I or II
hitch. Refer to the tractor operator’s manual for the
category of the tractor being 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 non-conforming 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 and Cat II
hitches require 1-1/8” lower and 1” upper diameter
hitch pins.
2.2 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. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
