1.0 INTRODUCTION

® *
The HARDI Navigator 550M, 800M and 1000M centrifugal models
consist of a hydraulic pump or P.T.O. driven pump with P.T.O. shaft,
frame with tank, ESC controls (Electric Control) and Manifold System.
The Navigator 550M model is available with either the hydraulic folding
Eagle™ SPB series spray boom available in 45', 50', 60' or 66' widths
or a manual fold boom (MB) available in 35', 40', 42', 45' or 50' widths.
*
The Navigator 800M /1000M model is available with the hydraulic
folding Eagle™ SPC series spray boom available in 80' 88' or 90'
widths.
The tanks, made of impact proof and chemical resistant poly eth ylene,
have a purposeful design with rounded contours which allows for
efficient cleaning and draining. The tanks are designed with a large
deep sump, so that they can be completely emptied even when the
sprayer is used on slopes up to 15% inclination. A remote operated
valve drain is fi tted for effi cient draining.
The ESC control unit consists of: ON/OFF control, pressure regulating
1
valve, 2 / " pressure gauge and distribution valves with pressure
2
equalization.
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 centralized location.
The Eagle™ coil spring suspended 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 with a 'joystick' control handle. An optional electrical 'DH'
control for closed center hydraulics is available. Both versions require
single and double acting hy drau lic outlets on the tractor as well as a
12V connection for the HZ model. The MB (manual fold boom) offers
hydraulic height adjustment and hydraulic wing tilt as options.
