rear tunnel baffles (Fig. 8).
2. Install the center tunnel baffle to the front tunnel
baffle. The flange on the center baffle goes over and
behind the front baffle (Fig. 8).

3. Align the cutting chamber baffle so the baffle flange is
3–1/2 in. (89 mm) from the top of the cutting chamber
(Figures 9 and 10).
Important Make sure the baffle flange is 3–1/2 in.
(89 mm) from the top of the cutting chamber and there is
blade clearance of 3/8 in. ±1/16 in. (Figures 9 and 10).
4. Clamp the baffle in place.

Installing the Discharge Tubes
Refer to the bagger operators manual for installing the
discharge tubes.
Installing the Blade
Note: In certain mowing conditions, improved bagging
performance can be achieved by using bagging blades.
Contact an Authorized Service Dealer for the proper
blades for different mowing conditions.
1. Install the blade onto the spindle shaft (Fig. 13).
Important The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.
2. Install the spring disk and blade bolt (Fig. 13). Torque
the blade bolt to 85–110 ft-lb (115–150 Nm).
3. Rotate the blades to ensure there is clearance between
the blade tips and the baffles.
4. If contact is made, do not use the mower. Check and
make sure the baffles are installed properly.
Important Do not use the mower if blades contact the
baffles.
