Attaching
Discharge
Chute
All 600 Model Series
600 through 699
NOTE:
The hex flange nut has
a normal (right-handed)
thread pattern. Do NOT
attempt to force the nut
in the incorrect direction.
Doing so may damage the
nut and create a safety
hazard.
NOTE:
The retainer strap is
fitted at position B on
the discharge chute.
However, on older models
of tractors, you will have
to change the position of
the strap depending on
the location of the grass
catcher pin on the deck.
Remove the retainer strap
from position B on the
discharge chute to posi-
tion A or C corresponding
to the position of the
grass catcher pin at A,
B or C on the deck. See
Figure 24.
Attaching The Blades
1. Remove the blades from your tractor's cutting deck
as follows.
2. Remove the cutting deck from beneath the tractor,
(refer to Deck Removal in the MAINTENANCE sec-
tion of your tractor's operator's manual for detailed
instructions) then gently flip the deck over to expose
its underside.
3. Place a block of wood between the center deck
housing baffle and the cutting blade to act as a
stabilizer, keeping the blades from turning when you
loosen the hex flange nuts.
4. Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly.
NOTE: The hex flange nut has a normal (right-
handed) thread pattern. Do NOT attempt to force
the nut in the incorrect direction. Doing so may
damage the nut and create a safety hazard.
5. Install the new blades packed with the bagger. Be
sure to install the blade with the side of the blade
marked ''Bottom'' (or with a part number stamped
in it) facing the ground when the rider is in the
operating position.
6. Mount the SMALLER of the three blades to the
CENTER spindle. The remaining two blades are
interchangeable. See Figure 21.
7. Use a torque wrench to tighten the blade spindle hex
flange nut to between 70 and 90 foot-pounds.
8. Remount the cutting deck.
Attaching Discharge Chute
All 600 & 800 Model Series
1. On older models: Some older models may have a
clip already installed on the deck (See Figure 22) next
to the discharge chute opening. If this is the case, the
clip must be removed and a grass catcher pin, which is
inlcuded in your hardware pack, installed. To remove
clip, simply remove the lock nut, spring washer and hex
bolt that secure it. See Figure 23A.
2. Installing Grass Catcher Pin: A grass catcher pin
(G in Figure 4) and nut (H in Figure 4) have been
supplied in the hardware pack. Attach pin to the
deck in place of the clip just removed. Some units
may not have clip but will have an open hole for pin
installation. Follow Figure 23B for order of assem-
bly. Make sure to secure the pin tightly.
NOTE: The retainer strap is fitted at position A on
the discharge chute. However, on older models of
tractors, you will have to change the position of
the strap depending on the location of the grass
catcher pin on the deck. Remove the retainer strap
from position A on the discharge chute to position
B or C corresponding to the position of the grass
catcher pin at A, B or C on the deck. See Figure 24.
