5.2.4Blade drive belt tension: No adjustment necessary.
5.2.5Hydro 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.

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 “forward” position as shown in Figures 4 & 5 and move the speed control lever to the
Note: The park brake must be disengaged and the OPC levers must be held down whenever the speed control lever is out of the neutral position or the engine will kill.
3.Squeeze the respective drive lever until an increased resistance is felt; this is where neutral should be.
For Standard Pistol Grip Models: Make sure you have not reached the end of the neutral lock latch slot. If you have, shorten the drive lever linkage.
If the wheel turns while holding the drive lever in neutral, the neutral control linkages need to be adjusted. If wheels stop then go to step 7.
