HARDI MEGA 230 / 350 CENTRIFUGAL OPERATORS MANUAL
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
becoming increasingly conscious of crop protection input costs and the
vital need for cost effective spray 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 HARDI sprayer 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 HARDI MEGA models consist of a pump, frame with a tank that has
either 230 or 350 gallon capacities, ESC-Controls (Electric Control),
Manifold system, P.T.O. shaft and a 60' hydraulic folding Eagle series
spray boom. The 230 gallon model will mount directly to a category II & III
3-point hitch as well as to a category II and category III quick hitch. The
350 gallon model will mount directly to a category III 3-point hitch and
category III & category IIIN quick hitch. A pin kit is available for mounting
the 350 gallon to category II 3-point link arms.
The tank, made of impact-proof and chemical resistant polyethylene, has
a purposeful design with no sharp corners, for easy cleaning. A large,
easy to read tank contents indicator is placed in front of the tank. A step
and platform is placed at the right hand side of the sprayer for easy
access to the tank filling hole.
The ESC (electric control) unit consists of: on/off control valve, pressure
regulating valve, pressure gauge and distribution valves with pressure
equalization feature.
The "Manifold System" features color coded three way valves on suction
and pressure sides of the liquid control system. It allows for safe and
simple use of the sprayer and accessories from one position.
The Self-Cleaning Filter screens out impurities from the spray solution
which are recirculated back to the main tank while clean solution is
constantly being supplied to the boom.
The Eagle hydraulic series boom is available with either 3(HY model) or 5
(HZ model) hydraulic cylinders. The base version being the HY model,
includes boom height adjustment and fold/unfold features all controlled
from the tractor. The HZ model has all the same features as the HY
model but also includes individual wing tilt and fold as added features.
Both versions require single and double acting hydraulic outlets on the
tractor as well as a 12V connection for the HZ model.
