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 re-
moved 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. Operating the mower with
a tractor that does not have adequate power may damage the tractor engine. Exceeding recommended maximum
horsepower may cause mower damage by overpowering the unit in heavy cutting conditions.
Tractor 3-Point Lift
The tractor 3-point hitch must be rated to lift at least 675 lbs if attaching a HDTH5, 740 lbs if attaching a HDTH6.
The mower is designed to be mounted on tractors with a CAT I or Quick Attach 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 I dimensions or CAT l Quick Attach 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.
CAT I Standard Hitch, 7/8” lower and 3/4” upper diameter hitch pins. (Refer to Figures 3-3 & 3-5).
CAT l Quick Attach Hitch, 1-7/16” Lower and 1-1/4” upper hitch pins diameter. (Refer to Figures 3-4 &
3-5).
Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight
carriers can be purchased through an authorized tractor dealership.
