OPERATION
3.3 Tractor Horsepower
The horsepower required to operate the mower depends on many factors including the vegetation to be cut,
terrain condition, operator experience, and condition of the mower and tractor. For most mowing condition, the
RHD62 mower requires a tractor with at least 25HP, RHD74-30HP, RHD-88-40HP and RHD96-50HP.
Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
3.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
815 lbs. If attaching a RHD62, 930 lbs. if attaching a
RHD74, 1035 lbs. if attaching RHD88, and 1170
lbs. if attaching a RHD96 flail.
RHD mowers can attach to tractor’s with either a
CAT I or II hitch. Refer to the tractor operator’s
manual for the category of the tractor used. If the
hitch does not conform to ASABE CAT I or II
dimensions, the mower may not fit or raise properly.
Consult an authorized dealer for possible
modification procedures to mount nonconforming
hitches.
Use the correct hitch pins for the hitch category
being used. For a CAT I hitch, 7/8” lower can 3/4”
upper diameter hitch pins are used and CAT II
hitches require 1-1/8” lower and 1” upper diameter
hitch pins.
3.2 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
