OPERATION
Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the 260 mower requires a tractor with at least 35 HP, the 272 mower requires a tractor with at least
45 HP and the 284 mower requires a tractor with at least 65 HP. Operating the mower with a tractor that does
not have adequate power may damage the tractor engine. Exceeding 90 HP (Model 260) and 100 HP (Model
272 & 284) may cause mower damage by overpowering the unit in heavy cutting conditions.
2.3 3-Point Hitch
The tractor 3-point hitch must be rated to lift at
least 1000 lbs. (Model 260), 1200 lbs. (Model 272)
and 1500 lbs. (Model 284). The Model 284 is
designed to be mounted on a tractor with CAT II or
CAT III 3-Point or CAT II Quick Hitch.
Refer to the tractor operator’s manual for the
category of the tractor being used. If the hitch
does not conform to ASAE dimensions, the mower
may not fit or raise properly. Consult an authorized
dealer for possible modification procedures to
mount non-conforming hitches.
Depending on the hitch category, certain size pins
are used to attach the mower to the tractor. CAT I
hitches require 7/8” lower and 3/4” upper diameter
hitch pins. Quick Hitch requires 1-7/16” diameter
lower pin and 1-1/4” diameter upper pin. CAT II
hitches require 1-1/8” lower pins and 1 inch upper
pins. CAT III hitches require 1-7/16” lower pins
and 1-1/4” upper pin diameters.
Our 3-Point Quick Hitch is designed to connect to
a Quick-Attach coupler making mounting and
dismounting your mower easier. The 3-Point
Quick Hitch is also designed to connect the mower
to a tractor’s 3-point linkage without the use of a
Quick-Attach Coupler.
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
