• Disengage attachments before: refuelling, removing an attachment, making adjustments (unless the adjustment can be made from the operator’s position).

• When the machine is parked, stored, or left unattended, lower the cutting means unless a positive mechanical lock is used. Slopes are a major factor related to loss-of-control and tip- over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not drive on it. Control of a ride-on machine sliding on a slope will not be regained by the application of the brake. The main reasons for loss of control are: insufficient tire grip on the ground, speed too fast, inadequate braking, the type of machine is unsuitable for it’s task, lack of awareness of the ground conditions, incorrect hitching and load distribution.

• See your authorized dealer for recommendations of availableweights to improve stability. • Mow up and down slopes, not across.• Remove obstacles such as rocks, tree limbs, etc.• Watch for holes, ruts, or bumps. Uneven terrain could overturnthe unit. Tall grass can hide obstacles.• Use slow speed. Choose a low gear so that you will not haveto stop or shift while on the slope. • Use extra care with grass catchers or other attachments.These can change the stability of the unit. • Keep all movement on the slopes slow and gradual. Do notmake sudden changes in speed or direction. Do Not

• Do not start or stop on a slope. If tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.• Do not turn on slopes unless necessary, and then, turn slowlyand gradually uphill, if possible.• Do not mow near drop-offs, ditches, or embankments. Themower could suddenly turn over if a wheel is over the edge ofa cliff or ditch, or if an edge caves in.• Do not mow on wet grass. Reduced traction could causesliding.• Do not try to stabilize the unit by putting your foot on theground.• Do not use grass catcher on steep slopes. Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. This mowing deck is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed. Never operate on slopes greater than 17,6 percent (10°)which is a rise of 1m vertically in 6m horizontally. When operating on slopes use additional wheel weights orcounterweights. See your dealer to determine which weightswhich weights are available and appropriate for your unit. Select slow ground speed before driving onto slope. Inaddition to front and rear weights, use extra caution whenoperating on slopes with rear-mounted grass catcher. Mow UP and DOWN the slope, never across the face, usecaution when changing directions and DO NOT START ORSTOP ON SLOPE. WARNING

FRONTEN - 14 Features & Controls Throttle / Choke Control The throttle controls engine speed. Move the throttle up to increase engine speed and down to decrease engine speed. Always operate at FULL throttle. Note: Moving the throttle control fully forward closes the choke. A warm engine may not require choking. CONTROL FUNCTIONS The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section. Figure 1. Tractor & Mower Controls Please take a moment and familiarize yourself with the name, location, and function of these controls so that you will better understand the safety and operating instructions provided in this manual. Trans. Release Lever on Rear of Tractor PTO Lever The PTO (Power Take-Off) lever engages and disengages the blades. To engage the PTO, move the lever forward. To disengage the PTO, move the lever all the way back. You will feel the lever lock into both the engaged and disengaged positions. Note: The operator must be seated firmly in the tractor seat for the PTO to function. Also note that the tractor will not start unless the lever is in the disengaged position. Ground Speed Control Lever The tractor’s forward & reverse ground speed is controlled by the ground speed control lever. The ground speed is selected from a continuous range. Moving the lever forward in the F range increases FORWARD tractor motion, and moving the lever back in the R range increases REVERSE tractor motion. The further the lever is moved in either range, the faster the tractor will travel in that direction. Note: Depressing the clutch/brake pedal is NOT necessary when changing speeds or directions. Placing the lever in the N position puts the transmission in NEUTRAL, and ceases tractor motion. (Apply & set the Parking Brake before leaving the operator’s position). Always mow with the engine speed at full throttle. Note: If the terrain is rough, hilly, or sloping, use a slower forward speed. If the grass is wet or over 76 mm high, use full engine speed with a low forward speed so the mower will have enough power to cut the grass.EN - 15 English Deutsch Français Features & Controls

SAFETY INTERLOCK SYSTEM TESTS

This unit is equipped with safety interlock switches and other safety devices. These safety systems are present for your safety: do not attempt to bypass safety switches, and never tamper with safety devices. Check their operation regularly.

BBEN - 22 Operating the Tractor Temporary Storage (30 Days Or Less) Remember, the fuel tank will still contain some gasoline, so never store the unit indoors or in any other area where fuel vapor could travel to any ignition source. Fuel vapor is also toxic if inhaled, so never store the unit in any structure used for human or animal habitation. Here is a checklist of things to do when storing your unit temporarily or in between uses:

• Keep the unit in an area where children will not come into contact with it. If there’s any chance of unauthorized use, remove the keys and disconnect the spark plug wires.

• If the unit can’t be stored on a reasonably level surface, chock the wheels.

• Clean all grass and dirt from the mower. Note: If storing your tractor between winter snow removal jobs in a cold area, we suggest that you fill the fuel tank at the completion of each job to prevent water condensation in the fuel tank. Wait for engine to cool before filling tank. Long Term Storage (Longer Than 30 Days) Before you store your unit for the off-season, read the Maintenance and Storage instructions in the Safety Rules section, then perform the following steps:

1. Drain crankcase oil and refill with a grade of oil that will

be required when unit is used again.

2. Prepare the mower deck for storage as follows:

a. Remove mower deck from the unit. b. Clean underside of mower deck. c. Coat all bare metal surfaces with paint or light coat of oil to prevent rusting.

3. Clean external surfaces and engine.

4. Prepare engine for storage. See engine owner’s

5. Clean any dirt or grass from cylinder head cooling fins,

engine housing and air cleaner element.

6. Cover air cleaner and exhaust outlet tightly with plastic or

other waterproof material to keep out moisture, dirt and insects.

7. Completely grease and oil unit as outlined in the Normal

8. Clean up unit and apply paint or rust preventative to any

areas where paint is chipped or damaged.

9. Be sure the battery is fully charged. Battery life will be

increased if it is removed, put in a cool, dry place and fully charged about once a month. If battery is left in unit, disconnect the negative cable.

10. Drain fuel system completely or add a gasoline

stabilizer to the fuel system. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all safety instructions and storage precautions in this manual to prevent the possibility of fire from the ignition of gasoline fumes. Remember, gasoline fumes can travel to distant sources of ignition and ignite, causing risk of explosion and fire. Note: Gasoline, if permitted to stand unused for extended periods (30 days or more), may develop gummy deposits which can adversely affect the engine carburetor and cause engine malfunction. To avoid this condition, add a gasoline stabilizer to the fuel tank and run the engine a few minutes, or drain all fuel from the unit before placing it in storage.

STARTING AFTER LONG TERM STORAGE

Before starting the unit after it has been stored for a long period of time, perform the following steps.

1. Remove any blocks from under the unit.

2. Install the battery if it was removed.

3. Unplug the exhaust outlet and air cleaner.

4. Fill the fuel tank with fresh gasoline. See engine

manual for recommendations.

5. See engine owner’s manual and follow all instructions

for preparing engine after storage.

6. Check crankcase oil level and add proper oil if

necessary. If any condensation has developed during storage, drain crankcase oil and refill.

7. Inflate tires to proper pressure. Check fluid levels.

8. Start the engine and let it run slowly. DO NOT run at

high speed immediately after starting. Be sure to run engine only outdoors or in well ventilated area. STORAGE Never store the unit, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace, water heater, clothes dryer, etc.) and cause an explosion. Handle gasoline carefully. It is highly flammable and careless use could result in serious fire damage to your person or property. Drain fuel into an approved container outdoors away from open flame or sparks.

AEN - 40 Troubleshooting, Adjustment, & Service BATTERY SERVICE Checking Battery Voltage A voltmeter can be used to determine condition of battery. When engine is off, the voltmeter shows battery voltage, which should be 12 volts. When engine is running, the voltmeter shows voltage of charging circuit which normally is 13 to 14 volts. A dead battery or one too weak to start the engine may not mean the battery needs to be replaced. For example, it may mean that the alternator is not charging the battery properly. If there is any doubt about the cause of the problem, see your dealer. If you need to replace the battery, follow the steps under Cleaning the Battery & Cables in the Regular Maintenance Section. Charging a Completely Discharged Battery

1. Be aware of all the safety precautions you should

observe during the charging operation. If you are unfamiliar with the use of a battery charger, have the battery serviced by your dealer.

2. Always unplug or turn the charger off before

attaching or removing the clamp connections.

3. Carefully attach the clamps to the battery in proper

polarity (usually red to [+] positive and black to [-] negative).

4. Charge the battery until fully charged.

Jump Starting With an Auxiliary (Booster) Battery Jump starting is not recommended. However, if it must be done, follow these directions. Both booster and dis- charged batteries should be treated carefully when using jumper cables. Follow the steps below EXACTLY, being careful not to cause sparks. Refer to Figure 40.

1. Both batteries must be of the same voltage.

2. Position the vehicle with the booster battery

adjacent to the vehicle with the discharged battery so that booster cables can be connected easily to the batteries in both vehicles. Make certain vehicles do not touch each other.

3. Wear safety glasses and shield eyes and face from

batteries at all times.

4. Connect positive (+) cable to positive post of

discharged battery (wired to starter or solenoid).

5. Connect the other end of same cable to same post

marked positive (+) on booster battery.

6. Connect the second cable negative (-) to other post

7. Make final connection on engine block of stalled

vehicle away from battery. Do not lean over batteries.

8. Start the engine of the vehicle with the booster

battery. Wait a few minutes, then attempt to start the engine of the vehicle with the discharged battery.

9. If the vehicle does not start after cranking for thirty

seconds, STOP PROCEDURE. More than thirty seconds seldom starts the engine unless some mechanical adjustment is made.

10. After starting, allow the engine to return to idle

speed. Remove the cable connection at the engine or frame. Then remove the other end of the same cable from the booster battery.

11. Remove the other cable by disconnecting at the

discharged battery first and then disconnect the opposite end from the booster battery. Keep open flames and sparks away from the battery; the gasses coming from it are highly explosive. Ventilate the battery well during charging. WARNING Do not attempt to charge a frozen battery. Allow the battery to warm to 60° F (15.5° C) before placing on charger. WARNINGEN - 41 English Deutsch Français Troubleshooting, Adjustment, & Service Any procedure other than the preceding could result in: (1) personal injury or property damage due to battery explosion, (2) damage to the charging system of the booster vehicle or of the immobilized vehicle. Do not attempt to jump start and start with jumper cables a vehicle having a frozen battery because the battery may rupture or explode. WARNING For your personal safety, use extreme care when jump starting. Never expose battery to open flame or electric spark. When removing or installing battery cables, disconnect the negative cable FIRST and reconnect it LAST. If not done in this order, the positive terminal can be shorted to the frame by a tool.
