Mower Preparation - Disassembly
1. Park tractor on a hard, level surface such as a concrete
floor. Engage parking brake, disengage PTO, and stop
engine.

4. Using a pry bar, place the square end in the square hole
located in the end of the idler arm (c, Figure 2).
WARNING
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring
as the idler arm is being rotated. Injury may result if the
breaker bar is prematurely released while the spring is
under tension.
5. Carefully rotate the idler arm counter-clockwise.
6. Slide the mower drive belt (d) over the edge of the
right hand spindle pulley (e).

Operation
Before Operation
Clear the lawn of all sticks, stones, wire and other debris
which may be caught or thrown by the mower blades.
For best results, mow when the grass is dry. Wet grass
tends to clump and plug up the mower and grass catcher
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 engine running 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.
Look through the grass catcher tube to check for grass
flow. Do not open the grass catcher cover with mower
engaged.
If a large amount of cut grass is spilling out from under the
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.
WARNING
ALWAYS shut off the tractor. Disengage the PTO, and
allow all moving parts to stop BEFORE disconnecting or
clearing tube, or emptying grass bags.
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.
Mowing without the Turbo
If you need to mow without the turbo vacuum system in
place (for instance, if the grass is too wet to bag, but must
be mowed), you must remove the turbo from the mower
deck, and properly position the deflector BEFORE you
begin mowing.
WARNING
To operate without the collection system, the turbo
assembly MUST be removed and the deflector MUST be
in the down position.
The deflector is spring loaded. When removing the turbo,
hold the deflector up; then lower the deflector into the
normal operating position.
Recommended Accessories
If operating on slopes when a rear attachment is installed,
use front counterweights. Never operate on slopes greater
than 10°.
After Operation
The turbo housing and grass catcher tube should be
removed for cleaning. Remove the tube by unlatching
the lower tube rubber band from turbo housing. When
reattaching, make sure there is a snug fit between the
mower deck, turbo housing, and grass catcher.

Turbo Removal
DANGER
To operate without the collection system, the turbo
assembly MUST be removed and the deflector MUST be
in the down position.
The deflector is spring loaded. When attaching or
removing the turbo, hold the deflector up; then lower the
deflector into the normal operating position.
Removing the Turbo
For operation without turbo, the deflector must be properly
installed in the down position and retained by the spring
latch.
1. Remove the grass discharge tubes.
2. Remove knob (I, Figure 14), lockwasher (H) and flat
washer (G) from carriage bolt that secures turbo to
deck.
