6.4 Tracking adjustment
Before proceeding with this adjustment, be sure that the tire pressures are correct and the neutral adjustment and the steering control rod adjustment have been completed.
1.With the machine on a flat level surface, start the engine, release the parking brake and place the speed control lever into the speed that will most often be used.
2.Squeeze the steering control levers and release the neutral latch. Slowly release the steering control levers, allowing the machine to move forward.
WARNING
Before attempting to make any tracking adjustments, move the speed control lever to the neutral position, place the blade engagement switch in the off position, apply the parking brake, and move the steering control levers into the neutral position.
3.If the machine pulls to one side, stop the mower by placing the steering control levers in the neutral position. Using the adjustment wrench located on the left side of the machine, turn the tracking adjustment nut on the slower side counter clockwise until the machine tracks straight.
4.Bring the steering control levers back to the neutral lock position and check to see that the machine does not creep forward on the adjusted wheel.
5.If the machine creeps in neutral, you have moved out of the neutral band and will have to turn the tracking adjustment nut clockwise until the machine does not creep.
6.Repeat steps 1 and 2. If the machine continues to pull to one side, stop the mower by placing the steering control levers in the neutral position. Turn the tracking adjustment nut on the faster side clockwise until the machine tracks straight.
7.If tracking cannot be acheived, contact your Scag servicing dealer.
