General Operating Instructions
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, discharge tube, and grass
catcher cover.
Mowing with the Double / Triple Catcher
Always operate with throttle at full speed when
mowing.
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 discharge tube may be plugged or the
bags may be full — Disengage the blower (blades)
and remove the ignition key, wait for all parts to stop
and then empty the catcher or clear the discharge
tube.

General Operating Instructions
After Operation
For the blower:
1. The blower housing and discharge tube should be
removed for cleaning.
For the collection system:
1. Remove any accumulated debris from the inside of
the collection unit.
2. Remove any debris from the screen on the
underside of the lid.
NOTE: The lid screen can be partially removed for
easier cleaning and should be cleaned regularly.
3. Inspect the grass bags for wear or damage. Make
sure that there is a snug fit between mower deck,
blower housing, discharge tube, and grass catcher
cover.
WARNING
Disengage the blower (blades) and remove the
ignition key, wait for all parts to stop before
disconnecting or unlatching any parts attached
to blower or collection system.
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
Always wear hearing protection when
operating.
Storing the Grass Catcher
Clean the grass catcher thoroughly using a mild
detergent (other products may damage the discharge
tube). Remove any debris from 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 Collection System
To remove the blower, see the instructions in
Collector System Removal. All of the instructions
must be followed in Collector System Removal to
remove the collector, blower, collector hose, and front
weights, and the discharge chute properly installed
and and adjusted in the down position.
NOTICE
Be careful when turning away
from objects. The bagger may
collide with objects causing
damage.
NOTICE
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 the
manufacturer’s durability standards.
WARNING
Warning - Loss of traction and control hazard:
• Do not operate with only the collection system
installed.
• Do not operate with only the front counter
balance weights installed.
• Operate only with both the entire collection
system and front counter balance weights
installed and the collection system closed and
latched.

Installation
Figure 1. Upper Shock Mounting Positions
Installation
Rear Suspension Adjustment (Models
Equipped with Rear Suspension)
Many units equipped with rear suspension have
multiple upper mounting positions for the rear shock
assembly (A, Figure 1). If the unit that you are
installing the collection system on is equipped with
rear suspension, the upper mounting position of
the rear shock assembly must be re-positioned to
accommodate the additional weight of the collection
system.
Some units are equipped with two (2) upper shock
mounting positions and some units are equipped
with three (3) upper shock mounting positions. To
accommodate the additional weight of the collection
system the upper end of the shock mount assembly
must re-positioned so that the shock is in its most
vertical orientation.
If the unit that you are installing the collection system
on does not have additional upper mounting positions,
the spring’s pre-load must be adjusted. For unit’s with
additional upper mounting positions: if a stiffer ride
is desired after the rear shock is re-positioned to it’s
most vertical position, it can be achieved by adjusting
the spring’s pre-load.
To adjust the upper shock mounting position:
1. Park the machine on a flat, level surface. Engage
the parking brake, disengage the PTO, turn the
ignition switch to OFF, and remove the key from the
ignition.
2. Chock the front wheels of the unit to prevent the
machine from rolling.
3. Raise the rear of the machine and secure with jack
stands. The jack stands must be positioned under
the bumper of the unit.
4. Position the jack under the suspension cradle (or
the cross member that ties the suspension arms
together, depending on your unit) and slowly raise
the rear suspension to relieve the pressure on the
upper shock mounting bolts.
NOTE: This will require small adjustments to the
jacks position. The shock should move freely on the
mounting bolt when the pressure is relieved.
5. Remove the upper shock mounting hardware and
pivot the shock to the position that orients the
shock most vertically (position #2 for units with two
(2) upper mounting positions; position #3 for units
with three (3) upper mounting positions). Adjust
the jack to align the shock assembly to the shock
mounting hole.
6. Re-install the upper shock mounting hardware and
tighten securely.

7. Remove the jack from underneath the suspension
cradle (or suspension cross member, depending on
your unit).
8. Remove the jack stands from underneath the
machine.
To adjust the spring pre-load:
1. Park the machine on a flat, level surface. Engage
the parking brake, disengage the PTO, turn the
ignition switch to OFF, and remove the ignition key.
2. Chock the front wheels of the machine to prevent
the machine from rolling.
3. Raise the rear of the machine and secure with jack
stands.
4. Remove the rear drive tires.
5. To adjust the spring pre-load of the shock
assembly (A, Figure 2) insert the tip of the spanner
wrench (p/n 5022853) (B), that came with the zero-
turn riding mower, into the notch of the pre-load
adjuster (C). While holding the spanner wrench
in place with one hand, turn counter-clockwise
to increase the amount of pre-load. (Turning
clockwise will decrease the amount of pre-load.)
Make sure that both rear shock assemblies are
adjusted to the same pre-load position.
6. Re-install the rear drive tires. Torque the lug bolts
to 85-91 ft. lbs. (115-129 Nm). Remove the jack
stands from under the machine.
NOTE: If the spanner wrench is not located in a clamp
under the seat plate of your unit, it was included with
the publication packet for the zero-turn riding mower.

Installation
Installing the Collector Assist Spring
(IS600Z Models Only)
Due to the extra weight of the collection system, it is
necessary to install the collector assist springs (A,
Figure 3) on the IS600Z models.
1. Park the machine on a flat, level surface.
Disengage the PTO, stop the engine and engage
the parking brake.
2. Chock the front wheels to prevent the machine from
rolling. Raise the rear of the machine and secure
with jack stands. The jack stands must be under
the bumper.
This will allow the shock to be relaxed and will
allow maximum space for the installation of the
collector assist spring.
3. Install the collector assist spring to the frame of the
machine and secure using the two (2) 3/8-16 X 1”
bolts (B), 3/8 washers (C), and 3/8 nylock flange
nuts (D).
4. Repeat the process for the other side of the unit.
5. Remove the jack stands from under the machine.
6. Remove the jack from under the suspension cross
member.
