4.2.4PTO Safety Switch Adjustment:

a)Stop engine and wait for all moving parts to stop. Engage parking brake. Remove key or spark plug wire(s).

b)With PTO disengaged and assist arm against the front assist arm stop, adjust the blade safety switch mounting bracket (if needed) until the bellcrank depresses the plunger by 1/4” (.64 cm).

c)Be sure the bellcrank DOES NOT touch the switch body or damage to the switch could occur.

d)Retighten switch mounting bracket.

4.2.5Engine to Mower Deck Belt Adjustment:

a)Stop engine and wait for all moving parts to stop. Engage parking brake. Remove key or spark plug wire(s).

b)Engage PTO.

c)Check belt guides under rear engine and front mower deck to see that they are properly set (See Section 4.2.7).

d)Belt must be tight enough so it does not slip during heavy loads while cutting grass. Over-tensioning will reduce belt and spindle bearing life. To adjust belt tension, loosen the 5/16" whizlock nut on turnbuckle and rotate the turn buckle; rotate turnbuckle toward rear of mower to tighten, and toward front of mower to loosen belt tension (See Figure 7).

For 48” Decks: If there is no adjustment left in the turnbuckle and the belt is still loose, the rear idler pulley can be repositioned in the front hole (See Figure 7). The belt guide located next to the pulley must also be repositioned in the front hole when the pulley is moved. The turnbuckle will need to be readjusted.

Check belt tension after the first hour of operation and at least twice during the first 24 hours of operation. Adjust as necessary.

Note: After readjusting the belt tension check the belt guide adjustment Section 4.2.7 and blade brake adjustment Section 4.2.6.
