Exmark TR23KC manual Figure Anti-Scalproller Installation, And Cutting Height Adjustment

c)Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one of the positions shown in Figure 9. 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) clearance to ground. Do Not adjust rollers to support the deck. Be sure roller bolts and nuts are installed with the spring disc washer between head of the bolt and mounting bracket.

Two types of anti-scalp roller assemblies are available. See Figure 9 to determine which assembly has been installed on the unit. Torque hardware as specified, or loss of roller may result.

Type A – Torque the 3/8 whizlock nut to 40-45 ft-lbs. (54-61 N-m) Type B – Torque the 3/8 nyloc nut to 30-35 ft-lbs. (41-47 N-m)

Torque the 3/8-24x2 Gr 8 hex capscrew to 50-55 ft-lbs (68-75 N-m)

AND CUTTING HEIGHT ADJUSTMENT

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 "c" to prevent damage to the rollers and/or bolt failure (See Figure 9).

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

6.2.2Transmission drive belt tension adjustment: No adjustment necessary.

6.2.3Mower deck drive belt: No adjustment necessary.

6.2.4Blade drive belt tension. No adjustment necessary.

6.2.5Neutral Centering Adjustment

a)The Neutral Centering Device adjustment should be made with the engine running at full throttle. First raise and securely block up the frame so that the drive wheels can rotate freely without contacting the ground.
