3.3 Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the TW84 mower requires a tractor with at least 60 HP for a lift unit and 30 HP for a pull type.
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.
3.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
1215 lbs.
The TW84 mower is designed to be mounted on a
tractor with a CAT II or III 3-point hitch. Refer to the
tractor operator’s manual for the category of the
tractor being used. If the hitch does not conform to
ASAE CAT II or III dimensions, the mower may not
fit or raise properly. Consult an authorized dealer
for possible modification procedures to mount
nonconforming hitches.
Depending on the hitch category, certain size pins
are used to attach the mower to the tractor. CAT II
hitches require 7/8” lower and 3/4” upper diameter
hitch pins. CAT III hitches require 1-7/16” lower and
1-1/4” upper diameter size pins.

3.2 Tractor Safety Devices
If transporting or operating the tractor and mower 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 mower. Never operate the tractor PTO with
the PTO master shield missing or in the raised position. OPS-U- 0004
