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

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.
