General Operating Instructions
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.
GENERAL OPERATIONG
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, 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.
After Operation
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.
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 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
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.
WARNING
Use two hands when adjusting the shock
assembly springs. The will prevent the wrench
from slipping while pressure is being applied.
