c)
Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one
of the positions shown in Figure 10. 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 10 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)

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 10.
NOTE:
When anti-scalp rollers are placed in these positions, reduced deck
flotation will result.

Hydro Drive Linkage Adjustment:
a)
Adjust Speed Control Linkage and Neutral Safety Switch
1. Stop engine and wait for all moving parts to stop.
2. Move speed control lever (located on console) to the full forward position
and check orientation of tabs on the ends of the speed control crank. See
Figure 11. These tabs should be pointing straight down at the 6 o’clock
position or slightly forward. Adjust threaded yoke at the bottom of speed
control linkage until tabs are positioned correctly. See Figure 11.
3. Pull speed control lever back to neutral. Check that the neutral safety
switch actuating tab has depressed the plunger of the switch so that
there is about 5/16” between the tab and the switch. See Figure 11. If
necessary, move the switch fore and aft.
