CHECK MOWER BLADE TIMING -

40" MOWERS
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 perpen-
dicular to each other as shown in Figure 31. If not,
proceed to step 3.
3. Use a block of wood (B, Figure 28) to prevent blade
rotation while loosening the capscrew.
4. Remove the capscrew (A, Figure 32), spring washer
(F), and spline washer (G).
5. Remove the alignment pin (E, Figure 32). Rotate the
blade (D) manually until the blades are perpendicular
to each other as shown in Figure 33. It may be nec-
essary to remove and rotate the blade adapter (C) to
align the blade hole and adapter hole.
6. Reinstall the alignment pin (E), spline washer (G),
spring washer (F) and capscrew (A). Use a wooden
block (B) to prevent blade rotation while tightening
the capscrew (A) to 61-75 N.m (45-55 ft. lbs.).
