5.2.6 Secondary belt

(48" only)

Stop engine and remove spark plug wire(s).

The secondary drive belt is adjusted via the belt tension

rod (See Figure 16). The 5/16" nyloc adjustment nut is

located at the rear, right corner of engine deck.

Proper belt tension (for the secondary belt) will require

about 10 lbs. side pull on belt, halfway between pulleys

(See Figure 16, Point B) to deflect belt 1/2”.

5.2.7 Belt Guide Adjustment

a) Stop engine and remove spark plug wire(s).

b) Engage the blade drive belt.

c) Check belt guide clearance on the mower deck. The

four welded belt guides on the mower deck should be

located 1/8" from belt. Adjust if necessary.

Check belt guides under the engine deck for proper

adjustment (See Figures 17 and 18). Adjust as necessary.

The disengaged belt should not drag or fall off

pulley when guides are properly adjusted.

NOTE: Belt guides are not installed on the same bolts on

the 32" and 36" models as on the 48" models.

NOTE

: These drawings are viewed from

underneath engine deck.
