GENERAL WARNINGS
• Know the mower controls, safety rules and how
to stop quickly. READ AND UNDERSTAND THE
MOWER OPERATOR’S MANUAL.
• Read and obey all safety decals.
• Wear appropriate ear, eye and breathing
protection.
• Only allow responsible adults, who are familiar
with the instructions, to operate the unit.
• Disengage the electric clutch (PTO). Shut off the
engine and wait for all moving parts to stop before
attaching, adjusting, or disconnecting any part of
the collection system.
• Check the collection system to make sure it is
bolted tightly to the rider.
• DO NOT operate the mower without either the
entire grass catcher or the deflector in place.
• Turn off the PTO switch to disengage the blades
when not mowing.
• DO NOT mow in reverse. Always look down and
behind before and while travelling in reverse.
• DO NOT turn sharply when travelling alongside a
building or any object. Slow down before turning.
• DO NOT carry passengers on the rider.
• When blower assembly is removed from the
mower deck, the deflector must be properly
installed.
• Collector bags are subject to deterioration
and wear during normal use. Inspect the bag
periodically for tears, holes or weak spots and
replace with a new bag that meets manufacturer’s
durability standards.
• If the mower stalls or the turbo blower chute plugs:
1. Disengage the electric clutch (PTO);
2. Stop the engine and remove the key;
3. Set the parking brake, and wait for all moving
parts to stop.
4. Remove the foreign object or clear the chute
with a piece of wood before restarting the
engine. NEVER place hands into blower
housing to clear jammed object. Blower
may rotate when object is removed.
• For added rider stability and to prevent tipping or
loss of control:
a. Use reduced speed on uneven ground and
when turning corners.
b. Reduce loads on hillsides. It is recommended
that the collection system be kept no more
than half full when negotiating any slopes. Start
mowing on slopes when the collection system
is empty.
c. Mow across the face of slopes; not up and
down.
• Never operate on slopes greater than 17.6%
(10°).
Read these safety rules and follow them closely. Failure to obey these rules could result in loss
of control of unit, severe personal injury or death to you, or bystanders, or damage to property or
equipment. This mowing deck is capable of amputating hands and feet and throwing objects.
The triangle in text signifies important cautions or warnings which must be followed.

Before Operation
Clear the lawn of all sticks, stones, wire and other
debris which may be caught or thrown by the mower
blades.
Check grass condition. If wet, wait until later in the
day. If grass is wet, the grass catcher is likely to
become plugged.
For efficient bagging, air circulation under the
mower deck, through the chute and into the bag
is very important.
For this reason, BEFORE YOU BEGIN MOWING
you should make certain the underside of the mower
and the underside of the catcher lid are free from
grass and debris.
Make sure that there is a snug fit between mower
deck, blower housing, tubes, and grass catcher
cover.
Mowing with the Double / Triple Catcher
Always operate with throttle at full speed when
mowing.
Always wear hearing protection when operating
grass catcher.
Grass should be cut often, and not too short. If grass
is too long or lush it may be necessary to keep
ground speed to a minimum or to cut only half the
width of the mower to prevent clogging. If grass is
long, operate with mower in high cutting position
for first pass, cutting again in a lower position on a
second pass.
Do not open the cover with mower engaged.
If a large amount of cut grass is spilling out from
under deck, the tube may be plugged or the bags
may be full— discontinue mowing, stop the rider,
disengage the PTO and then empty the catcher or
clear the tube.
WARNING
ALWAYS shut off the tractor. disengage
the PTO, and allow all moving parts to stop
BEFORE disconnecting or clearing tube, or
emptying catcher.
Before leaving the operator’s position for any
reason, engage the parking brake, disengage
the PTO, stop the engine and remove the key.
To reduce fire hazard, keep the engine, rider
and mower free of grass, leaves and excess
grease. Do not stop or park rider over dry
leaves, grass or combustible materials.
CAUTION
This machine produces sound levels
in excess of 85 dBA at the operator’s
ear and can cause hearing loss though
extended periods of exposure.
Wear hearing protection when operating this
machine.

After Operation
Remove any debris from the the screen on the
underside of the lid. Note: The lid screen can be
partially removed for easier cleaning and should be
cleaned regularly.
The blower housing and tube should be removed for
cleaning.
Inspect the grass bags for wear or damage. Make
sure that there is a snug fit between mower deck,
blower housing, tubes, and grass catcher cover.
Storing the Grass Catcher
Clean the grass catcher thoroughly using a mild
detergent (other products may damage the tube).
Remove any debris from the the screen on the
underside of the lid. The screen can be partially
removed for easier cleaning.
If paint has been scratched on metal parts, touch
up with paint, or apply a thin film of oil to prevent
corrosion.
Store in a dry area. Hang the catcher and catcher
bags to dry thoroughly before storing for a long period
of time. Always store away from moisture.
Mowing Without the Blower
For operation without the blower, the deflector must
be properly installed in the down position.
To remove the blower, reverse the installation steps.

INSTALLATION
Rear Suspension Adjustment
(Ferris Models Only)
For IS1500Z & IS2000Z Models:
The upper mounting position #2 (See Figure 1)
should be used when a rear-mount grass bagger
system is installed.
To adjust the upper mounting position:
1. Park machine on a flat, level surface. Disengage
the PTO, stop the engine and engage the parking
brake.
2. Raise the rear of the machine and secure with
jackstands. The jackstands must be under the
bumper. Chock the front wheels to prevent the
machine from rolling.
3. Position the jack under the cross member that ties
the suspension arms together and slowly raise
the rear suspension to relieve the pressure on the
upper shock mounting bolts.
NOTE: This will require small adjustments to the
jack’s position. The shock should move freely on the
mounting bolt when the pressure is relieved.
4. Remove the upper shock mounting hardware and
pivot the shock to the position #2 (see Figure 1).
Adjust the jack to align the shock mounts to the
shocks.
5. Reinstall the upper shock mounting hardware and
tighten securely.
6. Remove the jack from under the suspension cross
member.
7. Remove the jackstands from under the machine.
For All Other Ferris Models:
More spring pre-load should be used with heavy
weight operators.
To adjust the spring pre-load:
1. Park machine on a flat, level surface. Disengage
the PTO, stop the engine and engage the parking
brake.
2. Raise the rear of the machine and secure with
jackstands. Chock the front wheels to prevent the
machine from rolling.
3. Remove the rear drive tires.
4. See Figure 1. Using the supplied spanner
wrench (p/n 5022853), insert the tip of the wrench
into the notch in the pre-load adjuster. While
holding the wrench in place with one hand, turn
counter-clockwise to increase the pre-load, turn
clockwise to decrease the pre-load. Make sure
both shocks are set to the same amount of pre-
load.
5. Reinstall the rear drive tires. Torque the lug
bolts to 85-95 ft/lbs. (115-129 Nm). Remove the
jackstands from under the machine.
NOTE: Spanner wrench is located under the seat on
the right-hand side of the machine.
WARNING
Use two hands when adjusting the shock
springs. This will prevent the wrench from
slipping while pressure is being applied.

Ball Joint Hardware Replacement
(Ferris IS2000Z & IS2500Z Models with 52” Mower
Decks Only)
The hardware and spacers that secure the rear ball
joint (A, Figure 2) on the right hand front suspension
arm has to be replaced with the hardware and spacer
included with this kit. This change is necessary to
provide clearance for the blower unit and must be
completed before blower unit installation.
To replace the ball joint spacers and hardware:
1. Lower the front of the mower deck down onto
wooden blocks to relieve the tension on the front
deck hanger chains. Jack up the front of the
tractor frame until the weight is lifted off the front
caster wheels.
2. Remove the 3/4”-10 X 3-1/2” bolt (A, Figure 3)
and 3/4-16 nylon lock nut (B) that attaches the ball
joint (C) to the frame (D). Discard the bolt, and .75
X 1.75 X 1.00 spacer (E). Retain the .75 X 1.00 X
.25 spacer (F) and 3/4-16 nylon lock nut.
3. Install the new 3/4”-16 X 2-1/2” thin-headed bolt
(G), through the new .76 X 1.06 X .07 spacer
(H), the ball joint, the .75 X 1.00 X .25 spacer (F)
retained in step #2, the frame and secure using
