STEP 2:  
IMPORTANT: Clutch cable adjustments are made to the  
machine at the factory. The following adjustments are  
provided for reference only. Complete all items on the  
Pre-Operation Checklist as instructed.  
Check the clearance between the clutch cable and  
clutch spring. NOTE: Clearance between spring and  
cable is very important. Excessive clearance will cause  
drive system NOT to operate when wheel drive control  
handle is depressed. No clearance at all will cause  
mower to continue to propel itself when wheel drive  
control handle is released to stop mower movement.  
Slide vinyl spring cover (located at the end of clutch  
cable) up clutch cable to gain access to the end of  
spring and cable loop. With wheel drive control handle  
released, clearance between spring hook and cable  
loop should be 1/16” to 1/8”. If clearance is more or less  
than specified, unhook spring from clutch cable eye,  
then adjust by turning inner spring in an opposite  
direction than the outer spring. Rehook spring to clutch  
cable eye. Slide vinyl cover over the spring when  
correct clearance is reached. See Figure 13.

DISCHARGE ASSEMBLY  
NOTE: Discharge assemblies vary by model. Some  
assembly steps shown may not apply to your model.  
(Optional Accessory on Some Models)  
1: Install grass bag adapter to the deck in place of  
recycling cover. See Figure 16. Refer to side discharge  
deflector installation instructions.  
Your mower comes with a recycling cover already  
installed, and is ready for use as a recycling mower.  
The recycling cover is designed to remain on the  
machine at all times, unless alternate discharge  
operations are desired, such as side discharging or  
bagging. Recycling cover can be removed to  
accommodate alternate discharge components.  
ROUTE RECOIL ROPE  
AROUND PULLEY  
TO CHANGE DISCHARGE COMPONENTS:  
STEP 1: Remove knob nuts and internal/external tooth  
lock washers securing rear of recycling cover to mower  
deck. Remove cover. See Figure 14.

WASHERS  
A. Remove right rear bolt from engine recoil cover.  
B. Remove torx screw and nut securing rope guide  
pulley to bracket on bag adapter.  
C. Lay standoff between bolt holes in engine recoil  
cover and bag adapter pulley bracket. NOTE:  
position standoff so that bent end is toward engine  
recoil cover.  
FIGURE 14  
STEP 2: Install desired discharge component /  
assembly.  
D. Flip pulley over so that flange of steel bushing is  
under pulley. (The bushing will act as a washer  
between the pulley and standoff.)  
E. Reassemble pulley to bag adapter, and install  
supplied replacement bolt, fitted with thread sleeve,  
into recoil cover. Tighten all hardware securely.  
A. SIDE DISCHARGE DEFLECTOR  
Install deflector to deck in place of recycling cover, making  
sure that: 1) hole on outside front of deflector fits onto stud  
in front of discharge opening where front of recycling  
cover was originally installed, 2) slot on inside front of  
deflector slips under restraining nut on top of deck (under  
right front corner of engine), and 3) slot on inside rear of  
deflector slips onto stud behind rear of discharge opening,  
where rear of recycling cover was originally secured. See  
Figure 15. Install internal/external tooth lock washers and  
knob nuts on studs and tighten securely.

the top wire. Fold bag opening into a "Z" and install  
slider. See Figure 17.

the underside of the cutting blade. Remove foam shipping  
block from cutting blade. This must be removed before  
starting the engine.  
BAG  
SLIDER  
IMPORTANT: DO NOT tip machine with carburetor or  
spark plug down. Oil from crankcase will saturate the air  
filter and cause the engine to be hard to start or not start  
at all. If contamination does occur, the air filter will have  
to be replaced.  
“Z” FOLD BAG  
AS SHOWN  
Assembly is complete. Complete all items on the  
Pre-Operation Checklist as instructed.
