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. This mow-
ing deck is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed.
GENERAL WARNINGS
● Know the tractor controls and how to stop quickly.
READ THE TRACTOR OPERATOR’S MANUAL.
● Read and obey all safety decals.
● 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 tractor.
● 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 tractor.
● 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 tractor 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.
On slopes over 15% (8.5°), use two rear wheel
weights in addition to front counterweight. Never
operate on slopes greater than 30% (16.7°).

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, as the grass catcher is likely to become
plugged.
For efficient grass collection, air circulation under
the mower deck, through the chute and into the
grass catcher or cart 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 TURBO
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.
To check if grass is flowing up tube, view tube. Do not
open cover with mower engaged.
If a large amount of cut grass is spilling out from under
deck, the tube may be plugged or the catcher may be
full— discontinue mowing, stop the tractor, disengage
the PTO and then empty the catcher or clear the tube.
OPERATING WITHOUT THE TURBO
If you need to mow without the turbo vacuum collector in
place (for instance, if the grass is too wet to bag, but
must be mowed)—you must remove the turbo blower
from the mower deck, and properly position the deflector
BEFORE you begin mowing.
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, tractor
and mower free of grass, leaves and excess
grease. Do not stop or park tractor over dry
leaves, grass or combustible materials.
WARNING
To operate without the collection system, the
blower assembly MUST be removed and the
deflector MUST be in the down position.
The deflector is spring loaded. when removing
the blower, hold the deflector up; then allow the
deflector to go down into the normal operating
position.
RECOMMENDED ACCESSORIES
When operating on slopes with a rear attachment, use
front counterweights. If you will be operating on slopes
over 15% (8.5°) two rear wheel weights are recommended in addition to the front counterweights. Never operate
on slopes greater than 30% (16.7°).
AFTER OPERATION
The turbo blower housing and tube should be removed
for cleaning. Remove the tube by unlatching the lower
tube rubber band from blower housing. When reattaching, make sure there is a snug fit between the mower
deck, turbo blower housing, and grass catcher.

ADJUSTMENTS
Pulley Adjustments
If the mower deck belt has stretched over time, the
stacked idler pulley (B, Figure 11) may need to be
moved to the outer hole in the mower deck to take up the
belt slack.
If the mower idler pulley (B) is mounted in the outer hole
in the deck, then the turbo idler pulley (C) should be as
far toward the front as the slot will allow. If the stacked
idler pulley (B) is mounted in the inner hole, then the
turbo idler pulley (C) should remain as installed at factory.
To adjust:
1. Loosen the back-side idler pulley (C, Figure 11) hardware.
2. Move the idler pulley forward in the adjustment slot
and then re-tighten the hardware.
Upstop Adjustment
The upstop (E, Figure 10) prevents the deflector (F)
from contacting the top of the turbo. If the upstop is not
providing sufficient clearance, shim the upstop with
washers until the deflector does not contact the turbo.
STORAGE
Remove any debris from the turbo blower housing. If you
clean the housing, use a mild detergent only (other products may damage tube). 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, away from
moisture.
