Safety Rules
& Information
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. The triangle in text signifies important cautions or warnings which must be followed.
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.
• 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 only half full when
negotiating any slopes. Start mowing on slopes
when the collection system is empty.
c. Mow up and down the face of slopes; never
across the face of any slope.
• When operating on slopes, use front counterweights.
Never operate on slopes greater than 17.6% (10°).
SAFETY DECALS
This unit has been designed and manufactured to provide you with the safety and reliability you would expect
from an industry leader in outdoor power equipment
manufacturing.
Although reading this manual and the safety instructions
it contains will provide you with the necessary basic
knowledge to operate this equipment safely and effectively, we have placed several safety labels on the unit
to remind you of this important information while you are
operating your unit.
All DANGER, WARNING, CAUTION and instructional
messages on your rider and mower should be carefully
read and obeyed. Personal bodily injury can result when
these instructions are not followed. The information is for
your safety and it is important! The safety decals below
are on your rider and mower.
If any of these decals are lost or damaged, replace them
at once. See your local dealer for replacements.
These labels are easily applied and will act as a constant visual reminder to you, and others who may use
the equipment, to follow the safety instructions necessary for safe, effective operation.
DANGER
ROTATING CUTTING BLADE
Do not operate mower
without deflector or entire
grass catcher in place.
1704277

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.
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.
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.
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 and retained by
the spring latch (Derby models only).
To remove the blower, reverse the installation steps.

1. Install the blower assembly onto the mount bar (B,
Figure 31). Push on the blower from the outside to
obtain a tight fit between the blower housing and
mower deck. Tighten the 3/8” x 1” bolts (C) that fasten the mount bar to the mower deck.
2. Drill a 3/8” hole through the mount flange of the
blower mount bar and secure with a 3/8-16 x 1” bolt
(E) and 3/8-16 flange nut (D).
3. Adjust the blower brace until approximately 1/8”
clearance is obtained between the brace and the
chute mount bar. Tighten the 3/8-16 x 1” bolts (A).
4. Install the 3/8” x 4” clevis pin (A, Figure 32) and hair
pin clip (C) as shown.
5. Install the plastic cap (B) in the end of the blower
mount bar.
6. Pull the idler arm lever against the spring to install
the drive belt on the spindle pulley. The tension idler
should be approximately 3/4” - 1” away from the
blower housing when belt in installed. If not, remove
the drive belt and reposition the top idler pulley in the
inside row of holes until the measurement is
achieved.
7. Install the blower belt shield and secure with the
hardware previously removed.
8. Install the deck belt shield (D) and secure with the

Discharge Chute Reattachment
MOWING WITHOUT THE BLOWER
For operation without the blower, the deflector must be
properly installed in the down position and retained by
the spring latch (Derby models only).
To remove the blower, reverse the installation steps.
Reattaching the Discharge Chute
See Figure 33. Using the retainer pin and hair pin clip,
secure the discharge chute to the mower deck. Make
sure the chute mount tabs are in front of the tabs on the
mower deck. For the Derby mowers, you must also
reinstall the torsion springs and spacer to properly retain
the discharge chute.

Standard Hardware Sizing
When a washer or nut is identified as 1/2”, this is the
Nominal size
, meaning the
inside diameter
is 1/2 inch; if a
second number is present it represent the
threads per inch
When bolt or capscrew is identified as 1/2 - 16 x 2”, this
means the
Nominal size
, or
body diameter
is 1/2 inch; the
second number represents the
threads per inch
(16 in this
example, and the final number is the
body length
of the
bolt or screw (in this example 2 inches long).
