When the blade control bail is depressed, the system
senses that the operator is in the normal operator's
position.
For Units with a Blade Brake Clutch: When
the blade control bail is released, the system
senses that the operator has moved from the
normal operating position and will stop the blade.
For Units without a Blade Brake Clutch:
When the blade control bail is released, the system
senses that the operator has moved from the
normal operating position and will kill the engine.

Self-Propel Drive Bail (Self-Propelled
Units Only)
Located on the upper handle as shown in Figure 4.
When the self-propel drive bail is squeezed, the
unit will move forward based on how far the bail
is depressed toward the handle. When this bail is
released the unit will stop moving.
Throttle-Choke Lever (ECXHN21)
Located on the left side of the handle bar.
The lever is used to control engine speed. Moving
the throttle to the full forward (Choke) position will
place the lever in the choke position. The choke aids
in starting a cold engine. Moving the throttle control
forward will increase engine speed and moving it to
the rear will decrease engine speed.
Choke Control (ECXHNBBC21)
Located on the front left side of the engine as shown
in Figure 9.
The choke aids in starting a cold engine. Pulling
outward will place the control in the choke position.
Pushing the control inward shuts off the choke.
Blade Control Lock Lever (Blade
Brake Clutch Units Only)
The blade control lock lever is located on the right
side of the handle next to the Blade Control Bail as
shown in Figure 4.
Moving the blade control lock lever into the full
forward position releases the blade control bail.
Squeezing the blade control bail against the handle
engages the blade. Releasing the blade control bail
automatically disengages the blade. The blade control
lock lever will reset to lock the blade control bail.
Engine Stop Switch
Located on the left side of the engine in front of the
fuel tank as shown in Figure 5. The engine stop switch
is used on ECXHNBBC21 and ECXKABBC21 (see
Figure 9 and Figure 10 ).
Press the switch to “STOP” to kill the engine. Press
“|” before starting the engine.
