60in TITAN® HD 2000 Series Riding Mower

Before starting the machine each day, perform the Each Use/Daily procedures listed in .

New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.

The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 11).

Figure 11

The MyRide™ suspension system adjusts to provide a smooth and comfortable ride. You can adjust the rear 2-shock assemblies to quickly and easily change the suspension system. Position the suspension system where you are most comfortable.

The slots for the rear-shock assemblies have detent positions for reference. You can position the rear-shock assemblies anywhere in the slot, not just in the detent positions. The following graphic shows the position for a soft or firm ride and the different detent positions (Figure 12).

Figure 12

2. Softest position
3. Detents in the slots

Note: Ensure that the left and right rear-shock assemblies are always adjusted to the same positions.

Adjust the rear-shock assemblies (Figure 13).

Figure 13

You can change the location of the lights on the roll bar as shown in Figure 14.

To change the mounting location, perform the following:

1. Remove the screw (5/16 x 3/4 inch), locknut (5/16 inch), and tube clamp securing each light.

2. Install the 2 tube clamps to the roll bar in the desired location (Figure 14)

3. Secure each light to the tube clamps using the previously removed screw (5/16 x 3/4 inch) and locknut (5/16 inch).

   Note: Do not install the light in a location where it covers any roll bar decal.

Figure 14
