5. Voltmeter (Figure 4-1). Indicates the condition of the charging system. When the engine is running, in normal operating conditions, the needle should be in the 12 to 14 volt range.
6. Oil Pressure (Figure 4-1). Indicates engine oil pressure. Reference the engine operator's manual for further information.
7. Hourmeter (Figure 4-1). Indicates the number of hours the engine has been operated. It operates whenever the engine is running. It can be used to keep track of maintenance intervals and the amount of time required to perform various tasks.
8. Fuse Holders (Figure 4-1). There are two 20- amp fuses and one 40-amp fuse that protect the mower’s electrical system. To replace fuses, pull fuse out of the socket and install a new fuse.
9. Left Steering Control (Figure 4-1). Used to
control the mower's left wheel when traveling forward or reverse.
10.Right Steering Control (Figure 4-1). Used to control the mower's right wheel when traveling forward or reverse.
11.Parking Brake Control (Figure 4-1). Used to engage and disengage the parking brakes. Pull the lever back to engage the parking brakes. Push the lever forward to disengage the parking brakes.
12.Fuel Tank Gauge (Figure 4-1). Indicates the amount of fuel in the fuel tank.
13.Dump Valve Control Levers (Figure 4-2). Located 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 and torqued to 10ft/lbs during operation of the mower. Rotating the levers counter-clockwise allows the mower to be moved by hand (free- wheeling).
14.Deck Lift Foot Lever (Figure 4-1). Used to raise and lower the cutter deck.

15.Cutting Height Adjustment (Figure 4-1). Used to set the cutter deck at the desired cutting height.
16.Deck Release Lever (Figure 4-1). Used to lock the cutter deck in the transport position. Push the foot pedal forward and lift up on the release lever to release the cutter deck for normal mowing.
17.Temperature Gauge (Figure 4-1). Indicates the operating temperature of the engine.
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, the parking brake is engaged, the steering control levers are in the neutral position and the operator is in the seat. The interlock system shuts off the engine if the operator leaves the seat with the steering control levers not in the neutral position and/or the cutter blades engaged and the parking brake not engaged.
WARNING:
Never operate the mower with the interlock system disconnected or malfunctioning. Do not disengage or bypass any switch; injury to yourself and others or property damage could result.
