3.2.1 DISCHARGE CHUTE REPLACEMENT INSTRUCTIONS:
1. Position mower on a flat surface.
2. Stop engine, remove key, and wait for all moving parts to stop.1.
3. Remove two (2) capscrews connecting the discharge chute to the deck. Remove
the discharge chute.
For 48" decks with Serial Nos. 203376 and lower: Verify that the unit has
discharge chute tabs that measure 4" high from the top of the deck plate before
continuing with Step 4. See Fig 4.
For 44" decks, 52" decks, or 48" decks that have deck tabs that measure 2
3/8" high: Skip to Step 15.
4. Measure the distance between the front and rear swivel blocks on the right side
deck lift mechanism. Dimension A in Figure 3. Write this measurement down for
use during re-assembly.
5. Support the mower deck on blocks so that the chains on the right side are slack
when the deck lift handle is in the 4.5" height position (also transport position).
6. Set the deck lift handle to the 4.5" height position (also transport position) and
remove all force from the right side deck lift spring by loosening the nuts at the
front of the spring. See Fig. 3.
7. The supplied oversized 2.25" outside diameter (O.D.) flatwasher (Item 21) must
replace the existing flatwasher on the right side deck lift spring at the slotted
bracket to the rear of the spring (as shown in Fig. 3). This will keep the
discharge chute from entering the slot at the deck's lowest positions when chute
is in raised position for transport.
NOTE: Make sure step "6" has been performed to relieve spring tension before
proceeding.
8. Remove E-ring and washer holding the front deck mount swivel and pull the swivel
out of the deck lift shaft lever. Remove nuts, swivel block, spring nuts, washer, and
spring from threaded rod. Remove existing flatwasher that is positioned between
the spring and frame bracket and replace with supplied 2.25" O.D. flatwasher (Item
21). Re-assemble spring, washer, nuts and swivel to rod. Reinstall the swivel to the
deck lift shaft lever. Install washer and E-ring after reattaching swivel to shaft lever.
