Tractor Horsepower; 3-Point Hitch; Front End Weight - RHINO TW60 Operator's Manual

2.3 Tractor Horsepower

The horsepower required to operate the mower depends on several operating factors including the vegetation
to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most
mowing conditions, the CY60 mower requires a tractor with a minimum of 30 HP and the CY72 mower requires
a tractor with a minimum of 40 HP. Operating the mower with a tractor that does not have adequate power may
damage the tractor engine. Exceeding 75 HP may cause mower damage by overpowering the unit in heavy
cutting conditions.

2.4 3-Point Hitch

The tractor 3-point hitch must be rated to lift at least
850 lbs. if attaching a TW60 and 1050 lbs. if
attaching a TW72 mower..
TW60/72 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 ASAE Cat I or II
dimensions, the mower may not fit or raise properly.
Consult an authorized
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 and 3/4"
upper diameter hitch pins are used and Cat II
hitches require 1-1/8" lower and 1" upper diameter
hitch pins.

2.5 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. OPS-U- 0005
