Service Interval: Yearly
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). Use a wooden block to prevent blade rotation while tightening the capscrew (A) 30 +/- 3 Nm.
