PRODUCT OVERVIEW
How do you bring the cost of irrigating
large turf areas down to Earth? Install
gear-driven rotors that perform at low
pressures with low precipitation rates
while creating the most highly efficient
water distribution profile. The full-circle
I-60-36S and the 40˚ to 360˚ adjustable arc
I-60-ADS will provide these valuable
benefits through Hunter’s patented
innovative nozzling system—Precision
Distribution Control®. With Precision
Distribution Control®, our single nozzle
design reduces pressure requirements
while creating larger droplets that fight the
wind and maximize radius. For excellent
close-in coverage, gear driven diffuser
pins intermittently distribute the stream.
The result? Reduced system maintenance
and operating costs from large turf rotors
engineered to meet the most demanding
water and energy conservation needs.
Great for low pressure retrofit applications
as well. The I-60 rotor is setting new
standards for the landscape irrigation
industry, as no other 40-65 foot radius
rotor can match its outstanding performance
at lower operating pressures.
An Easy Choice for Installers
Irrigation installers prefer the I-60 rotor for
four simple reasons: it’s easy to install, it’s
easy to adjust, it’s guaranteed reliable and
it’s the best value money can buy.
Installation is easy because of the “through
the top” adjustment mechanism allowing
modifications to be made quickly and
precisely whether the sprinkler is on or
off, while the rubber cover protects the
adjustment sockets from the intrusion of
debris. The industry’s #1 continuously
improved gear-drive system, coupled with
the 3-spring reversing technology, guarantees
reliable operation and optimum performance.

There’s no better value on the market than
the Hunter I-60 and, with its patented
Precision Distribution Control®features
and Hunter’s years of experience in
gear-drive technology, it’s no wonder the
I-60 rotor has established itself as the
professional’s choice.

PRODUCT FEATURES
AND BENEFITS
Patented Precision Distribution
Control®…
Assures even coverage at low pressures
The rotor’s single nozzle design features
Precision Distribution Control®for reduced
turbulence and maximum radius. With
gear driven pins that intermittently diffuse
the stream, Precision Distribution Control®
creates water-efficient performance while
it minimizes runoff and waste.
Operates with Lower Working Pressure...
The most power efficient rotor in the
industry
Because of its unique nozzle design based
on mechanical diffusion, only the I-60 can
make the claim that it operates efficiently
at low pressures. Large radius rotors
(50-65') (15-19.8 m) designed for large
turf or landscaped areas require a base
pressure in the range of 60-90 psi
(3.5-6.2 bars) to reach radius’ in the 60
foot (18.2 meter) range. At 40 psi (2.8 bar)
the I-60 is able to reach 62' (18.9 m)
making it the clear winner for systems
without the luxury of higher pressures or
for retrofits into systems that have had a
reduction in operating pressure over time.

Six Interchangeable Nozzles…
Truly uniform coverage and fast
identification
With every sprinkler in the I-60 group you
get six free interchangeable nozzles that
accurately go the distance. The nozzles
range from 50-66 feet (15.2-20.1 m) and
from 6.5-20.4 gpm (1.48 - 4.63 m3/hr)
(24.6 - 77.2 l/min.). Each nozzle is
color-coded and numbered for quick and
easy identification. The nozzle number
indicates the approximate flow rate for the
nozzle at 60 psi. The I-60 comes with the
#18 nozzle as the standard factory installed
nozzle, but can be ordered with any
pre-inserted nozzle for convenience and
timesaving installation.
Dual Flange I-60-36S Nozzles
Single Flange I-60-ADS Nozzles
Integral Rubber Cover with Membrane
Covered Sockets…
Keeps dirt out, permanently installed
The I-60 combines a small 13/4" (10 cm)
diameter exposed surface area with a soft
rubber cover to make the rotor ideal for
play areas. Because
the cover is securely
attached, it will
always give the
adjustment sockets
the protection of a
flexible membrane
to keep dirt out.

5
Heavy Duty Spring…
Positive retraction in the harshest conditions
Any turf area is unsafe
when sprinklers stay up
long after they’ve quit
running. Not only can
someone trip over a
sprinkler and injure him
or herself or break the
head that fails to retract,
but also rotors like this
can become easy targets
for vandalism. Because
of the extra beefy
stainless steel spring,
the I-60 rotors retract
every time, all the time.
Easy Arc Adjustment…
For fastest, hassle-free adjustment, wet or
dry, up or down
Because of its reversing full circle and
part-circle operation in one unit, the I-60
Adjustable Arc Rotor (I-60-ADS) is an
“all-in-one” sprinkler. With its 40˚ to 360˚
Adjustable Arc, most odd shaped areas can
be irrigated with a quick turn of the Hunter
wrench. The I-60 can be adjusted up or
down, wet or dry, for maximum convenience.
The 8:1 adjustment ratio changes the arc
45˚ for each full turn of the wrench and
the arrows on the rubber cover clearly
define the adjustment direction with plus
(+) and minus (-) symbols. Only one rotor
is needed to cover those curving walkways
and odd-angled turf areas.
Anti-Drain Check Valve…
Saves water, reduces liability
The built-in anti-drain check valve is
standard on I-60 rotors. The check valve is
designed to keep back a maximum of 10'
(3 m) of water pressure. Preventing low
head drainage eliminates washouts and
wasted water, and may also prevent
accidents from occurring and pests from
showing up. Also, due to water staying in
the pipes, installers may benefit from the
reduction of potential surge damage.
Heavy-duty Water Lubricated Gear
Drive…
Enduring reliability, year after year
First introduced about 20 years ago and
still being continuously improved, the
water lubricated gear drive system in the
I-60 is patterned after one of Hunter’s
famous heavy-duty golf rotors, ensuring
you with reliability and time proven
optimum performance.

6
Patented V-Stat Self-adjusting Stator…
Drives more power and adds years to
sprinkler life
The I-60 requires no specially installed
parts or adjustments to ensure constant
speed of rotation. With the self-adjusting
VStat™, the I-60 is provided up to twice the
driving force to the gear drive while adding
years to the sprinkler’s life. This is
accomplished through the stator’s patented
turbine isolation technology, a breakthrough
that all but eliminates gearbox wear due to
upward and lateral water thrust.
Standard Stainless Steel Riser…
Reliable retraction; longer riser seal life
The I-60's standard stainless steel riser
protects the riser and riser seal from
scratches and wear due to the increased
durability of stainless steel in harsh and
sandy soil conditions. Stainless steel
eliminates possible scoring on the riser and
riser seal, which can lead to premature
leaking and unsafe riser “stick-ups.”
PRODUCT FEATURES
AND BENEFITS (CONT.)
3-Spring Reversing Mechanism…
Reliability when it’s needed
Installers and end-users will have no
worries with the most reliable adjustable
arc reversing mechanism in the industry.
Our patented 3-spring, reversing technology
won’t hang up and get locked at the
critical directional shift point.
5 Year Warranty…
Hunter Industries backs up the products
A full five-year warranty by Hunter
communicates to our customers that
the I-60 is a rotor that stands up to the
environment. The end-user can be
assured of a quality product with a
guarantee of dependable operation.
Date Coding…
The easy way to identify exactly when your
rotor was manufactured
All the Institutional Series Rotors including
the I-60 have the manufactured date code
stamped on the bottom of the riser stem.
The I-60’s heavy-duty filter must be
removed first to read the code (a flat-blade
screwdriver works well for this). The date
is stamped with a 4-digit code – the first
two digits representing the month, the last
two digits indicating the year (e.g., 05 00
stands for May 2000).
