b) Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in
one of the positions shown in Fig. 7. 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. Torque to 40-45 ft-lbs, or loss of roller may result.
c) 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 7).
NOTE: When anti-scalp rollers are placed in these positions, reduced
deck floatation will result.
5.2.2 Pump drive belt tension adjustment:
No adjustment necessary.
5.2.3 Cutter deck drive belt:
No adjustment necessary.
5.2.4 Blade drive belt tension:
No adjustment necessary.
5.2.5 Hydro Drive Linkage Adjustment:
a) Adjust Speed Control Linkage and Neutral Safety Switch
1. Stop engine.
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 (fig. 8). 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 (fig. 8) until tabs are positioned correctly.
3. Pull speed control lever back to neutral. Check that the dimension
between the bottom forward tip of neutral switch actuating tab
(located at the left hand rear corner of fuel tank) and the top of the
fuel tank support is 7/8" (fig. 8). If it is not, bend tab on speed control
crank to attain 7/8" dimension.
SPEED CONTROL LINKAGE LENGTH
ADJUSTMENT OF 7/8" DIMENSION
b) Adjust Neutral Control Linkages
1. Raise the rear of the machine up onto jack stands high enough to
raise the drive wheels off of the ground.
2. Start the engine and move the throttle ahead to the full throttle position.
Place the neutral lock latches in the drive position as shown in Figure 4
and move the speed control lever to the "mid-speed" position.
