IMPORTANT

National Mower Safe Operation Practices

For Riding Mowers

1.Know control functions and how to stop quickly. READ THE OWNER’S MANUAL.

2.Wear approved safety glasses or goggles when operating the mower.

3.Do not allow children to operate mower. Do not allow adults to operate mower without proper instruction.

4.Do not carry passengers. Keep children and pets at a safe distance from an operating mower.

5.Clear the work place of objects which might be picked up by the blades and thrown.

6.Disengage all reel clutches and shift into neutral before attempting to start the engine (motor). Disengage main clutch before shifting reel clutches.

7.Disengage power to the reels and stop the engine (motor) before leaving the operator’s position.

8.Disengage power to the reels and stop the engine (motor) before making any repairs or adjustments.

9.Disengage power to the reels when transporting or not in use.

10.Take all possible precautions when leaving the mower unattended, such as, shifting into neutral, setting the parking brake, stopping the engine and removing the ignition key.

11.Do not stop or start suddenly when going uphill or downhill. Mow up and down the face of steep slopes – never across steep slopes. Do not exceed a slope of 25o in any direction.

12.Reduce travel speed on slopes and in sharp turns to prevent tipping or loss of control. Use extreme caution when changing direction on slopes.

13.Watch for holes in the terrain and other hidden hazards.

14.Watch for dangerous traffic when crossing or near roadways.

15.Never direct the discharge of material from operating reels toward bystanders nor allow anyone near the mower.

16.Handle gasoline (petro)l with CAUTION - it is highly flammable.

a.Use an approved gasoline (petrol) container.

b.Never remove the fuel tank cap or add gasoline (petrol) to a running or hot engine. Never fill the fuel tank indoors. Wipe spilled gasoline (petrol) immediately.

c.Open garage doors to allow ventilation if engine is run inside – exhaust fumes are dangerous. Do not run engine in any enclosed area.

17.Keep the mower in good operating condition. Make sure that all safety switches are operating properly and all safety guards are in place at all times, except during servicing.

18.Keep all nuts, bolts, and screws tight to be sure that the mower is in a safe working condition.

19.Never store the mower, with gasoline (petrol) in the tank, inside a building where fumes could reach an open flame or spark. Allow the engine to cool before storing in any enclosure.

20.Keep the engine free of grass, leaves or excessive grease to reduce a fire hazard.

21.The mower and reels should be stopped and inspected for damage after striking a foreign object. The damage should be repaired before restarting and operating the mower.

22.Do not change the engine governor settings or overspeed the engine.

23.Proceed as follows when mowing:

a.Mow only in the daylight or in good artificial light.

b.Never make a cutting height adjustment while the engine (motor) is running.

c.Shut the engine (motor) off when removing grass or unclogging reels.

24.This machine is to be used only as a grass cutter or lawn mower.

WARNING– California, USA residents are required by law (CA PRC 4442 & CA H & SC 13005) to equip their engines with spark arresters when operating in flammable vegitation. Arresters must be obtained from your engine dealer and are not available from National Mower Company.

OPERATION

The following is a description of the machine controls and their function. Refer to Figure B.

1.Steering Wheel

2.Throttle Control - Regulates mowing and travel speeds. Moving lever up and forward will increase speed. Moving lever down and back will reduce engine speed (for starting and idling engine). Never operate the mower at speeds faster than necessary to do a good, safe job.

3.Ignition Lock - Secures the machine electrical system when unattended. Insert and turn key clockwise to turn

ignition on, counterclockwise to off and key removal position.

IMPORTANT

Tractor will not start, even though ignition is on UNLESS:

A.Transport Clutch is disengaged

B.Mowing Clutch is disengaged

C.Operator is seated on the tractor

D.Wing Mower is disengaged

Page 14

NL84OMCE-1/99-6C

4.Ampmeter—Optional

5.Hourmeter—Optional

6.Choke—Control and operation is covered in the engine manual.

Moving machinery can be dangerous if not operated properly. Follow all safe operation suggestions as as listed on Safe Operation Practices, Page 10.

7. Foot Brake —Designed to stop the mower. The pedal is depressed with foot to engage. It is necessary to slow

the tractor by lowering throttle and disengaging clutch lever before applying brake to prevent excessive wear and engine overload.

8. Main Clutch—Provides power to the cutting units and tractor drive. Engage clutch by moving lever forward, disengage by moving lever back (toward operator). Use this control during all mowing and slower transporting situations–withorwithouthavingthecuttingunitsengaged.

ENGAGE SLOWLY

IMPORTANT

Advance lever slowly before full engagement. Always disengage this drive before disengaging wing or rear mower drive or when stopping or leaving machine.

9. Wing Mower Lift—Provides a convenient means of manually lifting the wing mowers a few inches temporarily while the operator remains seated on the mower. It should not be used for trailer transport or storage.

Always disengage the wing and rear mower clutches (controls 13 and 14, Page 15) when not mowing and also to minimize reel and bed knife wear.

Hooks are provided at the end of each lifting chain for securing wing mowers when transporting or storing the mower. The recommended procedure is as follows:

1.Stop Mower completely.

2.Disengage Main Clutch Control (Control 8, Page 15).

3.Engage Brake Locking Lever (Control 11, Page 15).

4.Raise Wing Mowers by pulling Lifting Lever fully rearward.

5.Leave Seat and lift the outer end of each Wing Mower by grasping Handle provided on outer ends of mowers.

6.Insert the Lift Hook on each Lifting Chain through the slotted holes in the Hook Bracket Weldment and also through the loops of each Switch Rod.

NATIONAL® 84" TRIPLEX—CE

10. Differential Shift—Provides three gear positions:

Forward, neutral (center position) and reverse. Move lever forward and to the right (toward operator) until pin is beside metal tab to lock differential in a forward gear. Pin must be located in slot of tab for the neutral position and to the left of the tab (away from operator) for the reverse gear position.

Differential does not have synchro-meshed gears so you have to feel engagement.

Do not shift gears while unit is in motion or damage to differential could result.

11.Brake Locking Lever—Locks brakes in engaged position. Depress brake pedal fully. Brake lever will lock when lever is moved forward fully so that it travels over center. Refer to Detail A of Figure B.

12.Rear Mower Lifter Handle—Raises rear mower to the transport position. Pull handle up, forward and over center to lock in an UP position.

13.Rear Mower Clutch Shift Lever—Engages drive to rear mower. Pull lever forward and away from center of machine to disengage clutch jaw. To engage, pull lever forward and toward the center of machine to engage locking pin.

14.Wing Mower Clutch—Engages drive to wing mowers.

Raise lever and spring action will move lever out to engaged position. Disengage clutch by moving lever toward center of the machine, over stop and down to lock position.

Never engage drive unless wing mowers are in the lowered, cutting position.

15. TRANSPORT CLUTCH PEDAL

FOR TRANSPORT ONLY. Use when mowers are Up and Disengaged. DO NOT USE FOR MOWING!

Disengage Main Mowing Clutch (control 8) and shift to forward gear (control 10). Slowly move left foot forward to engage and back to disengage. Control disengages automatically when left foot is lifted.
