Installing the Upper Baffle
Complete the following procedure to convert to a mulching
mower.
1. Remove the lock nut (3/8 inch) securing the discharge
chute retaining rod to the deck. The lock nut is located
on the underside of the deck. Save the fastener for later
use.
2. Remove the bolts and flange nuts from the front side of
the deck that line up with the three tabs of the upper
baffle as shown in Figure 1.
Important The tabs in the upper baffle will line up with
existing hardware on some decks. For example, the
fasteners on the anti-scalp roller brackets may need to be
removed to accommodate the upper baffle.
