Exmark COMMERCIAL 21 manual Stopping the Engine, Operation

Operation

5.For units without a Blade Brake Clutch: Hold the blade control bail to the handle.

6.Pull the starter handle lightly until you feel resistance, then pull it sharply. Allow the rope to return slowly.

7.For ECXHNBBC21 Units: Gradually push in the choke control as the engine warms up.

8.For ECXHN21 Units: When the engine starts, move the choke/throttle control back to the fast position.

Stopping the Engine

1.Bring the unit to a full stop.

•For units without a Blade Brake Clutch: Release the blade control bail. Both the engine and the blade should stop within three seconds.

•For units with a Blade Brake Clutch: Press the switch to “STOP” to kill the engine (see Figure 5).

Note: If the blade does not stop within 3 seconds after releasing the blade control bail, contact an Authorized Service Dealer.

2.Close the fuel shut-off valve, if equipped, when the machine will not be in use for a few days, when transporting, or when the unit is parked inside a building.

Operating the Self-Propel Drive (Self-Propelled Units Only)

The lawn mower is variable speed, the more you squeeze the drive bail the faster the machine travels.

1.Start the engine.

2.Squeeze the drive bail against the handle (see Figure 4).

Note: You can vary the ground speed by increasing or decreasing the distance between the ground speed control bail and the handle. Lower the control bail to decrease the ground speed when you are making a turn or if the lawn mower is moving too fast for you. If you lower the control bail too far the lawn mower stops self-propelling. Squeeze the ground speed control bail closer to the handle to increase the ground speed. When you hold the ground speed control bail tight against the handle, the lawn mower

self-propels at the maximum ground speed. Release the drive bail to stop moving when you use the lawn mower for trimming or whenever you leave the lawn mower.

3.To disengage the self-propel drive, release the drive bail.

Note: The mower comes with freewheeling clutches which make it easier to pull the mower rearward. To disengage the clutches, you may need to push the mower forward one inch (2.5 cm) or more after you release the self-propel drive bail.

Operating the Blade Control Bail (Units Without Blade Brake Clutch)

1.Squeeze the blade control bail against the handle.

2.Start the engine.

3.When the blade control bail is squeezed against the handle, the blade should engage.

4.Release the blade control bail. Both the engine and the blade should stop.

Operating the Blade Control Lever (Blade Brake Clutch Units Only)
