Dear Owner,
Thank you for purchasing a HARDI®product and welcome to the ever
increasing family of HARDI®sprayer owners.
Our sprayers and accessories are rapidly becoming a familiar sight on
North American farms. We believe that this results from growers becom-
ing increasingly conscious of chemical input costs and the vital need for
cost effective chemical application equipment.
Please take the time to thoroughly read the Operator’s Manual before
using your equipment. You will find many helpful hints as well as important
safety and operation information.
Some of the features on your EAGLE 3PT boom were suggested by
growers. There is no substitute for “on farm” experience and we invite your
comments and suggestions.
Please address your correspondence to the Service Manager at one of
these branches:
Sincerely,
Tom L. Kinzenbaw
President

1.0 INTRODUCTION
The EAGLE 3-point boom is a fully suspended hydraulically operated
spray boom featuring self-stabilizing trapeze suspension with coil
springs and a shock absorber to control the rate of boom movement.
The 3-point hitch frame meets the requirements for mounting the
sprayer to a CAT II or CAT III 3 point hitch or CAT II or CAT III-N quick
hitch coupler. The Hitch frame has a pump mounting plate (for PTO
and hydraulic drive pumps) as well as provision for mounting control
units and other accessories.
The 48’ and 60’ EAGLE 3-point boom also has parking stands
attached to the center frame which allows the boom to freestand when
not in use.
Three versions of the EAGLE 3-point boom are available. The “HY”
features simultaneous boom wing folding. The “HT” features
simultaneous wing fold and individual wing tilt through three tractor
double acting outlets. The “HZ” features electric hydraulic wing fold
(same as “HY”) plus individual wing tilt. This will require two tractor
double acting outlets and a 12v power supply. The hydraulic hoses that
attach to the tractor are fitted with 1/2” NPT quick couplers.
The EAGLE 3-point boom can be equipped with either single Snap-fit
or triplet nozzle bodies. Two pump and control systems are available
as options to the 3-point EAGLE boom. The Diaphragm pump system
features a HARDI®361 Diaphragm pump and electric control unit with
HARDI-matic, a mechanical rate controller, and a self-cleaning
pressure filter. The Centrifugal pump system features a Ace 206
hydraulically driven pump with an electric control unit. Both systems
are complete with adjustable agitation, constant pressure feature, in-
cab control box, system pressure gauge, and PTO shafts.
