CHAPTER 1
Operation
- The transmitter has two joysticks and a toggle switch. The
right joystick moves the mower in all directions while the left
joystick starts and stops the engine. The toggle switch is for
high or low speed. Use slow gentle movements with the right
joystick and avoid sudden full throttle movements keeping a
finger on the joystick at all times. You do not want to "flick"
the spring loaded joystick.
-The transmitter has a green and red mark on the left
joysitck. Red will stop the engine and green will start the
engine. Avoid starting the engine while the engine is running
by glancing down at your transmitter when starting and
stopping your engine.

- When powering up the system, it is best to always power on
the transmitter first and last when powering the system off so
the transmitter will always be able to communicate with your
mower.
-The transmitter has "trim control" to make small
adjustments to each joystick's "center". Example: If your
mower is pulling to the right when driving straight, adjust the
bottom trim control on the right joystick to the left until it
drives straight.
-The transmitter has "servo reversing". These are set and
configured from the factory to operate your mower properly.
If for some reason these are tampered with, you will need to
set them so the mower does what you tell it to do. The top
two switches relate to the movement control of your mower.
-The transmitter is equipped with "channel mixing". This
allows you to control movement with one joystick instead of
"tank steer" with two joysticks. If you ever replace the
transmitter, holding both joysticks down and out while turning
the new transmitter on will activate channel mixing. It will
give 3 beeps indicating channel mixing is enabled.
-The power switch on the rear of your mower will power on
your mower's electronics. Always remember to turn it off
while not in use.

-The deck height adjustment is a manual design allowing you
to raise and lower the deck from 2-6 inches. Never raise or
lower the deck while the engine is on and always shut the
engine off before approaching your mower.

Chapter 2
Safety
1) NEVER operate or allow someone to operate your mower
under the influence of drugs or alcohol.
2) NEVER place your hands or feet near moving parts.
Always allow the engine to cool before servicing.
3) NEVER approach your mower while the engine is running.
Always shut off the engine before approaching the mower.
4) NEVER adjust the deck height adjustment while the engine
is running.
5) NEVER operate your mower out of range. Always be at a
safe distance to observe the mower's surroundings. Be aware

of any objects that may be on the ground before mowing.
NEVER "test" the mower's 300 ft range of operation.
6) NEVER allow children to operate your mower. It is not a
toy.
7) ALWAYS make sure the batteries are charged before
operation. A weak mower battery can cause the on-board
electronics to have poor response characteristics. If the
battery struggles to start the mower, STOP! It is too weak to
safely operate the on-board electronics.
8) NEVER use a transmitter that has been dropped or may
have been subject to water damage. If your transmitter tells
your mower to do something, it WILL do it. Always know it is
telling your mower to do what you tell it to do.
9) In the event the electronics compartment is submerged or
exposed to excessive amounts of water, do not "test" the
mower to see if it works. Replace the electronic components
that were exposed to water.
10) When servicing the cutting blades from underneath the
mower, always remove the engine's spark plug first. It doesn't
take much to start the engine by turning the blade.
13) When mowing steep slopes, use caution not to lose
footing. NEVER attempt a zero-turn maneuver on a steep
slope.

14) When mowing steep slopes, NEVER keep the mower on
one side for long periods at a time. While the engine is
equipped with pressurized filtration, it is still better to alternate
sides when slope mowing.
15) For slopes too steep to maintain control, and going down
hill only is the only option, keep the spark plug side of the
engine up and this should only be used for short periods and
NEVER a continuous duty technique.

Chapter 3
Service and Maintenance
Blade Maintenance
Sharpening or replacing the blade on your mower is best
performed with the mower on the ground. For blade
replacement, use a 22" mulching blade with 3/8" center hole
and blade adapter slots. ALWAYS replace the lock washer and
use an impact/torque wrench to torque to 70-ft-lbs.
*CAUTION*
If hoisting the front end of your mower for easy acces to the
blade, use extra caution as serious injury or death may occur
from droppng the mower on you.

*DANGER*
When servicing the blade, ALWAYS remove the engine's spark
plug wire to prevent accidental engine start up from turning the
blade manually.
*DANGER*
Improper blade installation can result in serious injury,death or
property damage. ALWAYS install the blade with the proper
torque and new lock washer.
Sharpening the blades is easiest using a 60 grit flap disk
attachment on an angle grinder. A 45 degree edge is the best
balance between cut quality and blade durability.
Leveling the Deck
To level the deck, add/remove 3/8" flat washers
(shims)between the deck and linkage posts. Start with the

mower on a flat surface and measure from the ground to the
bottom edge of the deck making sure to gage from the same
edge on all four points.
NOTE:
Refer to the Engine owner's manual for regular service
recommendations for the engine. When slope mowing on a
regular basis, you will want to keep the engine oil topped off at
all times and change the oil and filter every 10 hours.
Battery Maintenance
Always start out with a fully charged battery bank. The
ZTR-22-SE and ZTR-22 use 2ea 12V 22ah SLA (Sealed Lead Acid)
AGM (Absorbant Glass Mat) batteries to make up the 24V DC
battery bank. You can charge them with a 24V battery
charger or wire them parallel and us a standard 12V auto
charger.
*CAUTION*
The ZTR-22-SE and ZTR-22 use very high current electronics.
NEVER allow the battery to short out or serious injury and/or
permenant damage to the battery bank may occur. Use extra
caution with metal tools or other objects near the battery bank.
Alternator Belt
To tighten the belt on the alternator, loosen the alternator
adjustment bolt (U.S. passenger side) 1/2 - 3/4 turn and pull
back on the alternator while re-tightening the bolt from the
bottom of the deck. If replacing the belt, use a 26" X 1/2"

V-belt from your local auto parts retailer.
TIP:
Use a block of wood and a hammer to gently tap the alternator
adjustment bolt back while in a snug fit position and then
tighten the adjustement bolt hands free.

Troubleshooting
1) Mower turns over but will not start.
a) Check fuel level and spark plug. You can spray one small
mist of engine starting fluid on the air filter.
b) Check engine shut off wires and relay to make sure the
electronics is not trying to turn off the engine as you are
attempting to start the engine. The relay should "tick" when
giving the command to shut off or start.
d) For other engine starting solutions, see the Engine owner's
manual.
2) The mower pulls to one side or tries to go by itself.
a) Adjust the trim controls on the side and under the right
joystick on the transmitter.

3) The mower will not power on.
a) Make sure the battery bank is charged and holding a
charge by using a volt meter to test the battery.
b) Make sure the battery posts are not lose and the cables
are firmly connected.
c) Make sure all wires and connections coming from the
electronics compartment are all in good shape.
4) I replaced the transmitter and now the mower does not
obey my commands.
a) You will need to configure the transmitter to the receiver.
First, enable channel mixing by holding the two joysticks out
and down before turning the transmitter on. The transmitter
will sound 3 beeps indicating channel mixing is enabled. Next
(with engine off) set the top two servo reversing switches on
the bottom of your transmitter. Swap the Ch1 and Ch2 wires
on the receiver if moving the joystick forward causes a left or
right movement on the mower.
5) All functions on the transmitter work except for one
a) Test the receiver by pulling the problem channel and try
using another channel. If this "fixes" the problem, you will
need to replace the receiver.
b) Switch the devices on the problem channel to see if the
device is bad. For example, if one of the engine start relays is
unresponsive, switch channels 1 & 2 to determine if the relay
board needs to be replaced.
*CAUTION* Remove the engine's spark plug wire before

troubleshooting engine starting problems.
c) If the engine will not try to start, and the above does not
resolve the problem, test the engine's starter with a volt meter
on the lead going to the engine starter.
d) If the engine will not try to start, also test the corresponding
relay for the engine start to hear it "tick" when giving the
command to start.
**Refer to the Engine owner's manual for more engine related
troubleshooting solutions.
