SAFETY INSTRUCTIONS
SAFETY STARTING
• Do not start the engine by shorting across starter terminals or bypassing the safety start switch.
• Do not alter or remove any part of machine safety system.
• Before starting the engine, make sure that all shift levers are in neutral positions or in disengaged positions.
• Never start the engine while standing on ground. Start the engine only from operator’s seat.
SAFETY WORKING
• Do not work on the machine while under the influence of alcohol, medication, or other substances or while fatigued.
• Wear close fitting clothing and safety equipment appropriate to the job.
• Use tools appropriate to the work. Makeshift tools, parts, and procedures are not recommended.
• When servicing is performed together by two or more persons, take care to perform all work safely.
• Do not work under the machine that is supported solely by a jack. Always support the machine by safety stands.
• Do not touch the rotating or hot parts while the engine is running.
• Never remove the radiator cap while the engine is running, or immediately after stopping. Otherwise, hot water will spout out from radiator. Only remove radiator cap when cool enough to touch with bare hands. Slowly loosen the cap to first stop to relieve pressure before removing completely.
• Escaping fluid (fuel or hydraulic oil) under pressure can penetrate the skin causing serious injury. Relieve pressure before disconnecting hydraulic or fuel lines. Tighten all connections before applying pressure.
• Do not open high-pressure fuel system. High-pressure fluid remaining in fuel lines can cause serious injury. Do not disconnect or attempt repair fuel lines, sensors, or any other components between the high-pressure fuel pump and injectors on engines with high pressure common rail fuel system.
• High voltage exceeding 100 V is generated in the ECU, and is applied to the injector. Pay sufficient caution to electric shock when performing work activities.

SAFETY INSTRUCTIONS
AVOID FIRES
• Fuel is extremely flammable and explosive under certain conditions. Do not smoke or allow flames or sparks in your working area.
• To avoid sparks from an accidental short circuit, always disconnect the battery negative cable first and connect it last.
• Battery gas can explode. Keep sparks and open flame away from the top of battery, especially when charging the battery.
• Make sure that no fuel has been spilled on the engine.
VENTILATE WORK AREA
• If the engine must be running to do some work, make sure the area is well ventilated. Never run the engine in a closed area. The exhaust gas contains poisonous carbon monoxide.
PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, clothing and cause blindness if splashed into eyes. Keep electrolyte away from eyes, hands and clothing. If you spill electrolyte on yourself, flush with water, and get medical attention immediately.
DISPOSE OF FLUIDS PROPERLY
• Do not pour fluids into the ground, down a drain, or into a stream, pond, or lake. Observe relevant environmental protection regulations when disposing of oil, fuel, coolant, electrolyte and other harmful waste.

1. TIRES
WARNING
• Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper equipment.
• Always maintain the correct tire pressureìo not inflate tires above the recommended pressure shown in the operator’s manual.
IMPORTANTQ
• Do not use tires other than those approved by KUBOTA.
• Dual tires are not approved.
NOTEQ
• When optional different-diameter tires are fitted on the machine, the travel speed display mode must be changed. Otherwise the travel speed will not get correctly displayed. Such mode switching is also needed when the original tires are back on the machine. (Refer to “4. CHECKING AND ADJUSTING” at “L9. ELECTRICAL SYSTEM” section in this manual.)
[1] TIRE SIZE AND INFLATION PRESSURE
IMPORTANTQ
• Excessive wear of tires may occur due to improper gear ratio.

[3] TIRE LIQUID INJECTION
Auxiliary weights can be used to increase traction force for plowing in fields or clayey ground.
Another way is to inject water or another liquid, such as a calcium chloride solution in the tires. Water must not be used in winter since it freezes at 0 °C (32 °F). The calcium chloride solution will not freeze and moreover, affords higher effect than water since its specific gravity is higher than that of water by about 20 %. Below is an explanation of calcium chloride solution injection.
IMPORTANTQ
• Do not fill the front tires with liquid. Injection
CAUTION
• When a calcium chloride solution is used, cool it before pouring it into the tire.
• Do not fill tires with water or solution more than 75 % of full capacity (to the valve stem level).
The following four ways can be used to inject water or a calcium
chloride solution into tires.
1. Gravity injection (Fig. 1)
2. Pump injection (Fig. 2)
3. Pressure tank injection (Fig. 3)
4. Injection directly from tap (only when water is being used).
NOTEQ
• Once injection is completed, reset the air valve, and pump air into the tire to the specified pressure.

W1012704
The Bi-speed turn clutch is controlled by the combination of the solenoid valve and the hydraulic flow.
When the 4WD / Bi-speed turn switch is pushed once, the front wheel drive (4WD) is engaged. When it is pushed twice, the Bi-speed turn system works. When it is pushed once more, the 2-wheel drive is engaged. The power train are available as follows.
2-wheel drive (4WD / Bi-speed turn switch is turned to “OFF”)
• The hydraulic system pressure is fed to between the neutral cover (3) and 4WD piston (4) at 4WD switch is turned
to “OFF” and hydraulic pressure does not come from 4WD solenoid valve to actuate the 4WD piston (4). So, the
hydraulic system pressure actuate the 4WD piston (4) to the neutral position and power is not transmitted from 33T
gear (2) to DT propeller shaft (1).
• When both brake pedals are depressed together while driving in 2WD mode, 2-brake switch operate the 4WD solenoid valve and activate to the 4WD mode. 4WD mode activate the 4WD braking system and the 4WD indicator lights up.
4-wheel drive (4WD / Bi-speed turn switch is turned to “4WD”)
• The 4WD / Bi-speed turn solenoid valve switches and supply the hydraulic pressure to actuate the 4WD piston (4) to engage the clutch pack together with the spring (5) tension force. The power is transmitted as follow. 33T Gear (2) → 35T Gear (13) → Clutch Body (4WD) (12) → 4WD / Bi-speed Turn Shaft (9) → DT Propeller Shaft
(1).
Engine stop
• The 4WD piston (4) engage to 4WD mode by spring (5) tension force and maintain the 4WD mode.
Bi-speed turn drive (4WD / Bi-speed turn switch is turned to “Bi-speed turn”)
• When front wheels reach approximately 0.56 rad (32 °) turning angle, its turning angle inspection switch is pushed to “ON” position and solenoid valve is operated. As a result, the Bi-speed turn is hydraulically engaged and the front wheel is revolved 1.5 times as many revolutions as the rear one.
• Bi-speed turn operates during the 0.1 to 9.5 km/h (0.063 to 5.9 m/h) traveling speed with 480/70R-28 rear tire. When the traveling speed is not within the specified speed, Bi-speed turn does not operated. 47T Gear (6) → 33T Gear (11) → Clutch Body (Bi-speed) (10) → 4WD / Bi-speed Turn Shaft (9) → DT Propeller
Shaft (1).

Turning Angle Inspection Switch
The turning angle inspection switch is on the front
wheel case support of left side, and this switch is controlled “ON” position or “OFF” position of Bi-speed turn.
When the 4WD / Bi-speed turn switch is set at the Bi-
speed turn position, if the turning angle is less than 0.56 rad (32 °), switch is “OFF” position, and current flows from the battery to the 4WD solenoid. If the turning angle exceeds approximately 0.56 rad (32 °), switch is “ON” position, and current flows to 4WD / Bi-speed turn relay’s coil, and the relay contact is set to Bi-speed turn position by electromagnetic force. Therefore, current from the battery flows to Bi-speed turn solenoid.

Being not electrified, it is kept in neutral position. Therefore, oil is flowed to neither Bi-speed turn clutch (5) nor 4WD clutch (4) when the 4WD / Bi-speed turn switch is switched to OFF position.
Oil of the hydraulic clutch is drained to the transmission case through the 4WD clutch (4) 2WD side (b).
When the 4WD solenoid is electrified, the oil pressure from the P port to A port to 4WD clutch (4).
And the oil pressure feeds the spool (4WD priority valve) (2) to change the hydraulic line.
The spool (4WD priority valve) (2) opens Bi-speed turn clutch (5) and tank port to prevent the 4WD clutch (4) and Bi-speed clutch (5) are not engage at the same time.

3. CHECKING AND ADJUSTING
CAUTION
• To avoid accidental short circuit, be sure to attach the positive cable to the positive terminal before the negative cable is attached to the negative terminal.
• Never remove the battery cap while the engine is running.
• Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, wash it away completely with water immediately.
• Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen becomes very explosive.
IMPORTANTQ
• If the machine is to be operated for a short time without battery (using a slave battery for starting), use additional current (lights) while engine is running and insulate terminal of battery. If this advice is disregarded, damage to alternator and regulator may result.

Switch
CAUTION
• For checking of electric circuit, use the circuit tester.
• As for the checking of sensors and switches, do the following order; check the battery, fuse and grounding line first, check by the test function of meter panel next, and check the connectors of panel or related electronic switch or sensor. If any defect is found there, check individual sensors or switches to see whether the defect exists at the sensor and switch side or at the wire harness side.
• When any defect is not found for sensors, switches and harness, replace meter panel with new one.
IMPORTANTQ
• When connecting or disconnecting the connector for the purpose of checking, be sure to turn OFF the main switch before hand. Moreover, pay attention not to allow the terminal to come in contact with other terminal or chassis while checking.
• When applying the test pin of the tester to the connector terminals, use care not to damage to the connector terminal.
Checking Connector Voltage, Sensor Resistance and Switch Continuity
1. Remove the panel cover, refer to “[1] CLUTCH PEDAL” at “2. CLUTCH” section (for ROPS model).
2. Remove the meter panel (1).
