ANTI-SCALP ROLLER BOLT INSTALLATION

ANTI-SCALP ROLLER AND CUTTING HEIGHT ADJUSTMENT

c)Adjust anti-scalp rollers for Normal Operating Conditions. Stop engine and wait for all moving parts to stop. Place rollers in one of the positions shown in Figure 13. Rollers will maintain 3/4 in. (19 mm) clearance to the ground to minimize gouging and roller wear or damage. For Maximum Deck Flotation, place rollers one hole position lower. Rollers should maintain 1/4 in. (6.4 mm) minimum clearance to ground. Do Not adjust rollers to support the deck. Be sure the spring disc washer is installed with the cone towards the nut. Tighten nuts properly.

d)When operating in extremely rough conditions it may be necessary to position the anti-scalp rollers one or two holes higher than described in "b" to prevent damage to the rollers and/or bolt failure (See Figure 13).

NOTE: When anti-scalp rollers are placed in these positions, reduced deck flotation will result.

5.2.2PTO engagement Linkage: Located between the PTO engagement lever on the left handle and the left rear corner of the engine deck.

a)Stop engine and wait for all moving parts to stop.

b)With PTO engaged, adjust the linkage length by loosening the lock nut on the turnbuckle and adjusting the turnbuckle so that the bolt on the bellcrank and the indicator arm align with each other within 1/16” (1.6 mm). See Figure 14. Tighten locknut against turnbuckle.

5.2.3PTO Safety Switch: Mounted to a tab on the inside left side of the fuel tank support.

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

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

d)Retighten PTO switch mounting hardware.
