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

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

aQuick-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.
