OPERATION
RX60/72/84 03/09 Operation Section 4-6
© 2009 Alamo Group Inc.
OPERATION
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the RX60 mower requires a tractor with at least 35 HP, the RX72 mower requires a tractor with at
least 45 HP and the RX84 mower requres a tractor with at least 65 HP. Operating the mower with a tractor that
does not have adequate power may damage the tractor engine. Exceeding 90 HP (Model RX60) and 100 HP
(Model RX72 & RX84) may cause mower damage by overpowering the unit in heavy cutting conditions.
3.3 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
1000 lbs. (Model RX60), 1200 lbs. (Model RX72)
and 1500 lbs. (Model RX84). The Model RX84 is
designed to be mounted on a tractor with CAT II ir
CAT is designed to bIII 3-Point or CAT III Quick
Hitch.
Refer to the tractor operator’s manual for the
category of the tractor being used. If the hitch does
not conform to ASAE dimensions, the mower may
not fit or raise properly. Consult an authorized
dealer for possible modification procedures to
mount non-comforming 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. Quick Hitch requires 1-7/16” diameter
lower pin and 1-1/4” diameter upper pin. CAT II
hitches requirie 1-1/8” lower pins and 1 inch upper
pins. CAT III hitches require 1-7/16” lower pins and
1-1/4” upper pin diameters.
Our 3-Point Quick Hitch is designed to connect to a
Quick-Attach coupler making mounting and
dismounting your mower easier. The 3-Point Quick
Hitch is also designed to connect the mower to a
tractor’s 3-point linkage without the use of a Quick-
Attach Coupler.
3.4 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
