5.Ammeter (Figure 4-1).Indicates the condition of the charging system. When the engine is running the needle should be at the positive end of the meter. If the needle is on the negative end of the meter, this indicates a discharge condition and the machine should be taken in for service.

6.Hour Meter (Figure 4-1). Indicates the number of hours the engine has been operated. It operates whenever the ignition switch key is in the ON position. It can be used to keep track of maintenance intervals and the amount of time required to perform various tasks.

7.Fuse Holders (Figure 4-1).Two 20-amp fuses protect the mower’s electrical system. To replace fuses, pull fuse out of the socket and install a new fuse.

8.Left Steering Control (Figure 4-1).Used to control the mower's left wheel when traveling forward or reverse.

9.Right Steering Control (Figure 4-1).Used to control the mower's right wheel when traveling forward or reverse.

10.Parking Brake Control (Figure 4-1).Used to engage and disengage the parking brakes and also used to lock the cutter deck from tilting up to high while traveling. Pull the lever back and lock in place to engage the parking brakes. Push the lever forward to disengage the parking brakes and engage the deck tilt lock.

11.Fuel Tank Gauges (Figure 4-1). Indicates the amount of fuel in the fuel tanks.

12.Dump Valve Control Levers (Figure 4-2). Located under the seat, on the hydraulic pumps, used to “free-wheel” the mower. Rotating the levers clockwise until they stop allows the unit to move under hydraulic power. The levers must be in this position during operation of the mower. Rotating the levers counterclockwise, one turn, allows the mower to be moved by hand (free-wheeling).

4.2 SAFETY INTERLOCK SYSTEM

The mower is equipped with a safety interlock system that prevents the engine from starting unless the deck drive is disengaged and the speed control is in neutral and the parking brake is engaged. The interlock system shuts off the engine if the operator leaves the seat with the speed control in the neutral position and the parking brake is not engaged and/or the cutter blades are engaged. It will also shut the engine off if the cutter deck drive is engaged and the hopper is raised.
