OPERATION
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
435 lbs.
The SE4 mower is designed to be mounted on a
tractor with a CAT I 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 I 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.

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
