1. Turn the PTO OFF, engage the parking brake, turn
the engine off, and remove the key. Remove the
mower deck (see “Mower Deck Removal”).
2. Turn the mower deck over and check the position of
the blades. The blades must be positioned
perpendicular to each other as shown in Figure 25.
If not, proceed to step 3.
3. See Figure 22. Use a block of wood to prevent blade
rotation while loosening the capscrew.
4. Remove the capscrew (A, Figure 24), spring washer
(B), and spline washer (E).
5. Remove the alignment pin (C). Rotate the blade (D)
manually until the blades are perpendicular to each
other as shown in Figure 25. It may be necessary to
remove and rotate the blade adapter (F) to align the
blade hole and adapter hole.
6. Reinstall the alignment pin (C, Figure 24), spline
washer (E), spring washer (B) and capscrew (A).
