It is very important to follow the instructions and operate the controls properly. _ _ F G H A B \ C K L Figure 4 A PTO (Blade Engage) Lever H Cruise Control Button B Choke Control (Super Bronco only) I Ignition Switch C D Parking Brake
ThrottleControlLever _ The throttle control lever controls the speed of the engine. When set in a given position, the throttle wilt maintain a uniform engine speed. .=_Choke ChokeControl Bronco: Moving the throttle lever all the way forward activates the engine's choke control. (M°_deFI°slY_J Super Bronco: The choke control knob is on the left side of the dash panel and is activated by pulling outward. Activating the choke control closes the choke plate on the carburetor and aids in starting the engine.
Headlights To turn on the headlights, rotate the same ignition key from ON position to ON/LIGHTS position of the ignition switch. To turn off the headlights, rotate the ignition key from ON/LIGHTS position to either ON position (to leave the engine running) or OFF position (to shut the engine off). _ WARNING: Never move the key into the Start position while the engine is running. Doing so may cause damage to your engine s starter.
NOTE:Cruise control cannot be engaged at the tractor's fastest ground speed. If the operator should attempt to de so, the tractor will automatically decelerate to the fastest optimal mowing ground speed. To disengage the cruise control, lightly depress either the brake pedal or the drive pedal. To change to the reverse direction when operating with cruise control, depress the brake pedal to disengage the cruise control and bring the tractor to a complete stop.
NOTE: Refer to the TRACTOR SET-UPon page 7 manual for gasoline and oil tiff-up instructions. 1. 2. 3. 4. 5. Insert the tractor key into the ignition switch. Place the PTO (Blade Engage) Lever in the disengaged (Blade Stop) position. Engage the tractor's parking brake. Move the throttle control lever into the CHOKE position (a warm engine may not require choking). Turn the ignitionkey clockwise to the START position. After the engine starts, release the key. It will return to the ON position.
Do not mow at high ground speed, especially if a mulch kit or grass collector is installed. For best results it is recommended that the first two laps be cut with the discharge thrown towards the center. After the first two laps, reverse the direction to throw the discharge to the outside for the balance of cutting. This will give a better appearance to the lawn. Do not cut the grass too short. Short grass invites weed growth and yellows quickly in dry weather.
