Operating Instructions, Parking Brake Lever

Operation

Parking Brake Lever

Located on left side of the console (Figure 3).

The brake lever engages a parking brake on the drive wheels.

Pull the lever up and rearward to engage the brake.

Push the lever forward and down to disengage the brake.

Height-of-Cut Foot Lever

The height of cut lever allows the operator to lower and raise the deck from the seated position (Figure 3). When the lever is moved forward, away from the operator the deck is raised from the ground and when moved back, towards the operator it is lowered toward the ground. Only adjust the height of cut while machine is not moving.

Hour Meter

Located on the control panel.

The hour meter is connected to a pressure switch installed in the engine block and it records the number of hours that the engine has run ( Figure 4). If the ignition switch is left on without engine running, hour meter will not run. The hour meter is standard on the 48 and 52 inch units and optional for the 42 inch unit.

Note: This switch is not a low oil sensor and will not alert the operator if the engine oil is low.

DANGER

Mowing on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. A loss of traction is a loss of steering control.

To avoid loss of control and possibility of rollover:

•Do Not mow near drop-offs or near water.

•Do Not mow slopes greater than 15 degrees.

•Reduce speed and use extreme caution on slopes.

•When mowing slopes, gradually work from lower to higher areas on the incline.

•Avoid sudden turns or rapid speed changes.

•Turn up, into an incline when changing directions on slopes. Turning down the slope reduces traction.

•Attachments change the handling characteristics of the machine. Use extra caution when using attachments with the machine.
