• Check brakes, clutch, linkage pins and other mechanical parts for improper adjustment and wear. Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (See MAINTENANCE on page 91.)

• Keep your tractor clean. Dirt, grease, and trash build up may contribute to fires and lead to personal injury.

• Use only implements meeting the specifications listed in this manual or implements approved by KUBOTA. (See IMPLEMENT LIMITATIONS on page 25.)

• Use proper weights on the front or rear of the tractor to reduce the risk of upsets. Follow the safe operating procedures specified in the implement or attachment manual.

not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.

2. CAB and ROPS

• KUBOTA recommends the use of a CAB or roll over protective almost all applications. This combination will reduce the risk of serious injury or death, should the tractor be upset. Check for overhead clearance which may interfere with a CAB or ROPS.

• Set the parking brake and stop the engine. Remove any obstructions that may prevent the ROPS from rising or folding. Do not allow any bystanders near the tractor. Always perform the adjustment from a stable position at the rear of the tractor. Hold the top of the ROPS securely when raising or folding. Make sure that all pins are installed and locked.

• If the CAB or ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the tractor.

• Never modify or repair any structural member of a CAB or ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure.

• A damaged CAB or ROPS structure must be replaced, not repaired or revised.

• If any structural member of the CAB or ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.

the tractor is equipped with a foldable ROPS, it may be temporarily lowered only when absolutely necessary for areas with height constraints. There is no operator protection provided by the ROPS in the lowered position. For operator safety, the ROPS should be placed in the upright and locked position and the seat belt fastened for all other operations.

OPERATING THE TRACTOR

Operator safety is a priority. Safe operation, specifically with understanding the equipment and environmental conditions at the time of use. Some prohibited uses which can affect overturning hazards include traveling and turning with implements, loads carried too high and so on. This manual sets forth some of the obvious risks, but the list is not, and cannot be, exhaustive. It is the operator's responsibility to be alert for any equipment or environmental condition that could compromise safe operation.

1. Starting to operate the tractor

respect to overturning hazards, entails

• Always engine or operating levers or controls. Adjust seat per instructions in the operating the tractor section. Never start engine while standing on the ground.

• Before starting the engine, make sure that all levers (including auxiliary control levers) are in their neutral positions, that the parking brake is engaged, and that both the clutch and the power take-off (PTO) are disengaged or “OFF”. Fasten the seat belt if the tractor has a CAB, a fixed ROPS or a foldable ROPS in the upright and locked position.

84.)

Follow the recommendations for proper ballasting.

• To avoid free wheeling: – Do not shift the shuttle lever while on a slope. – Stop completely by using the brakes and by

depressing the clutch pedal, then shift the shuttle lever.

– Start off after selecting shuttle direction, by

releasing the clutch pedal.

• When driving down a slope, ensure that 4-wheel

drive is engaged to increase traction.

5. Driving the tractor on the road

• Lock

the 2 brake pedals together to help assure straight-line stops. Uneven braking at road speeds could cause the tractor to tip over.

4. Operating on slopes

Slopes are a major factor related to loss-of-control and tip-over death. All slopes require extra caution.

• To avoid upsets, always back up steep slopes. If

• Observe all local traffic and safety regulations.

• Turn the headlights on. Dim them when meeting another vehicle.

• Drive at speeds that allow you to maintain control at all times.

• Do not apply the differential lock while traveling at road speeds. The tractor may run out of control.

• Avoid sudden motions of the steering wheel as they can lead to a dangerous loss of stability. The risk is especially great when the tractor is traveling at road speeds.

• Keep the ROPS in the upright position and wear the seat belt when driving the tractor on the road. Otherwise, you will not be protected in the event of a tractor roll-over.

• Do not operate an implement while the tractor is on the road. Lock the 3-point hitch in the raised position.

• Do not ride or stand on the step during operation. Riding or standing there could result in being crushed under the rear tire due to slippage or the step fracturing or being displaced by the unintended load.

WARNING

To avoid personal injury or death:

• During diesel particulate filter (DPF) regenerating operations, exhaust gases and exhaust filter components reach temperatures hot enough to burn people, or ignite or melt common materials.

• Keep tractor away from people, animals or structures which may be susceptible to harm or damage from hot exhaust gases.

• During regeneration, white exhaust gases may be visible. Do not allow regeneration in a non ventilated garage or confined area.

• During regeneration, do not leave the tractor.

1. Handling points

When a specific amount of particulate matter (PM) has accumulated refresh the DPF muffler by burning the PM inside it. This burning off work is called “Regeneration”. To extend operating time to reach this regeneration, and to avoid DPF muffler trouble, make sure to observe the following handling matters.

Fuel

Be sure to use ultra low sulfur fuel (S15).

IMPORTANT :

• Use of diesel fuel other than ultra low sulfur fuel may adversely affect the engine and DPF performance. Use of fuels other than ultra low sulfur fuel (S15) may not meet regulations for your region.

Engine oil

Use DPF-compatible oil (CJ-4) for the engine.

IMPORT

• If any engine oil other than CJ-4 is used, the DPF may become clogged earlier than expected and the fuel economy may drop.

2. DPF regeneration process

regeneration process can be performed by

DPF choosing “Auto regeneration” or “Regeneration inhibit” mode according to your job conditions. For jobs not affected by hot gases emitted during regeneration, “Auto regeneration” is advisable.

Auto regeneration mode

When starting the engine (switch operation is unnecessary), the “Auto regeneration” mode is automatically activated. With the auto regeneration mode on, when a specific amount of PM has accumulated, and the regeneration conditions are satisfied, the DPF will be automatically regenerated whether the tractor is in motion or parked. (See 6. Tips on diesel particulate filter (DPF)

regeneration on page 38.)

In this way, work efficiency is improved. For more details, read the “Auto regeneration” section of this manual. (See 3. Operating procedure for auto regeneration

mode on page 33.)

Regeneration inhibit mode

After starting the engine, if the “DPF inhibit switch” is pressed to turn on the switch lamp, the “Regeneration inhibit” mode will be activated. With “Regeneration inhibit” mode on, the PM which has accumulated inside the DPF will not be burnt, unless the operator performs the regeneration work manually. The “Regeneration inhibit” mode is effective for work in poorly ventilated work spaces. For more details, read the regeneration prohibition section of this manual. (See 4. Operating procedure for regeneration inhibit

mode on page 35.)

NOTE :

the engine is stopped once, the “Auto

• If regeneration” mode will be activated.

Prohibition of unnecessary idling operation

Generally exhaust gas temperature is, so the PM contained in exhaust gas will not be burnt, and begins to accumulate. Therefore, do not idle unnecessarily.

6. Tips on diesel particulate filter (DPF) regeneration

• Operation

higher in speed or load the engine operates,

The the higher the exhaust temperature rises. As a result, particulate matter (PM) inside the DPF is consumed and the regeneration process is required less frequently over time. The lower in speed or load the engine operates, the lower the exhaust temperature. Accordingly, less particulate matter (PM) inside the DPF is consumed and more accumulation of PM will occur, which requires frequent regeneration. Therefore, avoid prolonged idling if possible.

• Necessary conditions for “Regeneration”

When the conditions below are all satisfied, regeneration will start. However, if even one condition is deviated from during the process, the regeneration will be interrupted.

– The engine coolant temperature. – The DPF temperature. – The engine speed is 1200 rpm or higher.

• Usually it takes 15-20 minutes to complete the regeneration cycle. Actual regeneration time may depend on ambient temperature, exhaust temperature and engine speed.

• It is recommended to do the regenerating while the engine is warm.

• Do not unnecessarily start and interrupt the regeneration process. Otherwise, a small amount of fuel becomes mixed with the engine oil, which degrades the oil quality.

• While the DPF is being regenerated, the engine air flow rate is automatically limited to keep up the exhaust temperature. Because of this, the engine may sound differently, but this is normal for this engine.

• Just after the regeneration has ended, the DPF muffler remains hot. It is advisable to keep the engine running for about 5 minutes to allow cooling of the exhaust components.

2. DEF/AdBlue

CAUTION

o avoid personal injury:

• The urea aqueous solution (DEF/AdBlue®) is colorless, odorless and harmless. If the solution gets on your skin, immediately wash it away with water.

The DEF/AdBlue®, used as reducing agent of SCR, is a

32.5% urea aqueous solution. No qualification for handling the urea aqueous solution is needed. As well, the solution is not designated as a hazardous material. The product is available at gas stations, truck stops and specialty shops. Be sure to use the genuine product only. Do not use any poor-quality products, or the engine may have trouble and be damaged.

SELECTIVE CATALYTIC REDUCTION (SCR) MUFFLER

1. Outline of the SCR

The injector jets urea aqueous solution (DEF/AdBlue®) into

the muffler, and the solution is hydrolyzed with the heat of exhaust gas to generate ammonia (NH3). The ammonia generated thus is mixed with exhaust gas by the SCR muffler. In this way, nitrogen oxides (NOx) contained in exhaust gases are reduced by ammonia and decomposed into nitrogen and water vapor.

NOTE :

• On

the North American market, the high-grade NOx reducing agent called urea aqueous solution is sold in the name of diesel exhaust fluid (DEF). On the European and Japanese

markets, it is on sale under the trade name of AdBlue®.

3. Warning indication and countermeasures

Before starting the day's job, check the fluid level with the DEF/AdBlue® gauge on the instrument panel. If the fluid runs short during operation, the warning indicator lights up. If you continue running the machine as it is, the engine output will be limited by 50% or so. If running is continued, the engine will be limited to idling. (See 3.3 SCR system inducement display and

measures on page 40.)

These limitations are stipulated in conformity with the emission controls of each country and territory.

DTC can be used to diagnose the problem in engine and SCR muf For example “ENG P-208B”: The code beginning with the letter “P” or “U” is the DTC. If a DTC appears, immediately contact your local KUBOTA Dealer.

NOTE :

• When operating in cold weather, the DEF/ AdBlue® is automatically thawed while the engine is running. However, in weather conditions of under -30 ℃ (- 22 ℉), the DEF/ AdBlue® cannot be completely thawed and thus, a DTC (“ENG P-208B”) appears on the instrument panel's LCD screen. If the DTC (“ENG P-208B”) appears on the screen, stop the engine and restart it after 10 seconds. After restarting the engine, the DTC (“ENG P-208B”) will disappear and the thawing of the DEF/AdBlue® will resume. In case the DTC (“ENG P-208B”) remains on the screen even after restarting the engine several times, contact your local KUBOTA Dealer.

The limited engine output level:

• “Lv.1” (Level 1): Within 50% of max torque and 60% of engine speed. “Lv.2” (Level 2): Within engine near idling speed.

• After an error has occurred, it may be necessary for the engine output to become limited to “Lv.2”. Depending on trouble spots and contents, the indicator-prompted warnings and the engine output limits and timings may vary accordingly. The SCR warning status (from 1 to 3) represents the severity order of the engine output limitation. If the SCR system experiences abnormalities, an error code will be displayed, and it may be necessary to limit the engine output to idle status (“Lv.2”). For example, when a “ENG P-204F” error code is displayed, the engine output changes from unrestricted to “Lv.2” limited.

• Points after taking measures. After the engine has stopped and the DEF/AdBlue® has drained, if the amount that was refueled is less than the pre-drain amount, the SCR system may experience a malfunction (“P20F5” error code is displayed). When the error occurs, turn the key switch to “OFF”, wait for the SCR system to complete the purge process (this may take several minutes) and then turn the key switch to “ON” again in order to clear the SCR system malfunction.

For 5 minutes after engine start-up, allow the engine to warm up without applying any load; this is to allow oil to reach every engine part. If load should be applied to the engine without this warm-up period, trouble such as seizure, breakage or premature wear may develop.

1. Warm-up and transmission fluid at low temperature range

Hydraulic oil serves as transmission fluid. In cold weather This can cause delayed oil circulation or abnormally low hydraulic pressure for some time after engine startup. This in turn can result in trouble in the hydraulic system. To prevent the above, observe the following instructions: Warm up the engine at about 50% of rated rpm according to the following table:

OPERATING THE TRACTOR

OPERATING NEW TRACTOR

a new tractor is handled and maintained

How determines the life of the tractor. A new tractor just off the factory production line has been, of course, tested, but the various parts are not accustomed to each other, so care should be taken to operate the tractor for the first 50 hours at a slower speed and avoid excessive work or operation until the various parts become “broken-in”. The manner in which the tractor is handled during the “breaking-in” period greatly affects the life of your tractor. Therefore, to obtain the maximum performance and the longest life of the tractor, it is very important to properly break-in your tractor. In handling a new tractor, the following precautions should be observed.

1. Do not operate the tractor at full speed for the first 50 hours

• Do not start quickly nor apply the brakes suddenly.

• In

winter, operate the tractor after fully warming up

the engine.

• Do not run the engine at speeds faster than necessary.

• On rough roads, slow down to suitable speeds. Do not operate the tractor at high speed.

The above precautions are not limited only to new tractors, but to all tractors. However, they should be especially observed in the case of new tractors.

• Face

• Always keep steps and floor clean to avoid slippery

OPERATING FOLDABLE ROPS

WARNING

o avoid personal injury or death:

• When raising or folding the ROPS, apply the parking brake, stop the engine, and remove the key. Always perform the adjustment from the operator's seat.

• Fold the ROPS down only when absolutely necessary and raise it up and lock it again as soon as possible.

• Before proceeding to fold the ROPS, check for any possible interference with installed implements and attachments. If interference occurs, contact your KUBOTA dealer.

1. Folding the ROPS

1. Remove both lock pins.

2. Changing lubricating oil for new tractors

The lubricating oil is especially important in the case of a

new tractor. The various parts are not “broken-in” and are not accustomed to each other; small metal grit may develop during the operation of the tractor; and this may wear out or damage the parts. Therefore, care should be taken to change the lubricating oil a little earlier than would ordinarily be required. For more details, read the maintenance section of this manual.

WARNING

o avoid personal injury or death:

• Do not engage the front-wheel drive when traveling at road speed.

• When driving on icy, wet, or loose surfaces, make sure the tractor is correctly ballasted to avoid skidding and loss of steering control. Operate at reduced speed and engage frontwheel drive.

• 4WD model tractor is equipped with 4-wheel braking and appropriate care should be taken during hard braking.

• Do not brake suddenly. An accident may occur as a result of a heavy towed load shifting forward or loss of control.

• The braking characteristics are different between 2 and 4-wheel drive tractor models. Be aware of the difference and use carefully.

• Do not use Bi-speed turn at high speed.

• Bi-speed turn enables short and fast turns, therefore, become familiar with its performance before operating in close or confined areas.

PARKING THE TRACTOR

WARNING

o avoid personal injury or death:

T Before dismounting tractor

• Always set parking brake and lower all implements to the ground. Leaving the transmission in gear with the engine stopped will not prevent the tractor from accidental rolling.

• Stop the engine and remove the key.

1. Before lower all implements, place all control levers in their neutral positions, pull the parking brake lever to parking position, stop the engine and remove the key.

2. If it is necessary to park on an incline, be sure to chock the wheels to prevent accidental rolling of the tractor.

getting off the tractor, disengage the PTO,

(1) Constant RPM Management switch with indicator

NOTE :

• In

a mechanically-controlled engine, the engine speed changes according to increases and decreases in the load. For example, when working in a hilly area, the load increases and engine speed drops while ascending a slope, and conversely the engine speed increase and the load drops when descending. These changes in engine speed affect the travel speed and PTO-driven implements. In order to minimize these effects, the operator must make fine adjustments to the travel speed and hand throttle lever. When the Constant RPM Management switch in this tractor with its electronically controlled engine is turned “ON”, the engine speed will be kept nearly constant in response to a certain level of load fluctuations. This improves the accuracy of work without the need for troublesome manipulation of the travel speed and hand throttle lever.

• There is a limit to the range within which a constant speed can be maintained. If a load exceeding the engine performance is applied, the engine speed will drop.

• The purpose of Constant RPM Management is not to increase the engine power.

3. Operating on slopes and rough terrain

WARNING

o avoid personal injury or death:

• Always back up when going up a steep slope. Driving forward could cause the tractor to tip over backward. Stay off hills and slopes too steep for safe operation.

• Avoid changing gears when climbing or descending a slope.

• If operating on a slope, never disengage the clutch or shift levers to neutral. Doing so could cause loss of control.

• Do not drive the tractor close to the edges of ditches or banks which may collapse under the weight of the tractor, especially when the ground is loose or wet.

5. Directions for use of power steering

• Power running. Slow engine speeds make the steering a little heavier. While the engine is stopped, the tractor functions in the same manner as tractors without power steering.

• When the steering wheel is turned all the way to the stop, the relief valve is activated. Do not hold the steering wheel in this position for a long period of time.

• Avoid turning the steering wheel while the tractor is stopped, or tires may wear out sooner.

• The power steering mechanism makes the steering easier. Be careful when driving on a road at high speeds.

WARNING

o avoid personal injury or death:

• Before jacking up the tractor, park it on a firm and level ground and chock the front wheels.

• Fix the front axle to keep it from pivoting.

• Select a jack that withstands the machine weight and set it up as follows.

(1) Front end weights (2) Bumper

IMPORTANT :

•

Do not overload tires.

• Add no more weight than indicated in chart.

(1) Jack point

BALLAST

WARNING

o avoid personal injury or death:

• Additional ballast will be needed for transporting heavy implements. When the implement is raised, drive slowly over rough ground, regardless of how much ballast is used.

• Do not fill the front wheels with liquid to maintain steering control.

1. Front ballast

Add weights if needed for stability and improve traction. Heavy tend to lift front wheels. Add enough ballast to maintain steering control and to prevent tipping over. Remove the weight when it is no longer needed.

pulling and heavy rear mounted implements

Maximum weight

45 kg x 10 pieces

(1036 lbs.)

2. Rear ballast

Add weight to rear wheels if needed to improve traction or for stability. The amount of rear ballast should be matched to job and the ballast should be removed when it is not needed. The weight should be added to the tractor in the form of liquid ballast, rear wheel weights or a combination of both.

2.1 Rear wheel weights (option)

Rear wheel weights can be attached to the rear wheel. See

your implement operator's manual for required number of weights or consult your local KUBOTA Dealer about their usage.

1.1 Front end weights (option)

Front end weights can be attached to the bumper. See

your implement operator's manual for required number of weights or consult your local KUBOTA Dealer about their usage.

(1) Rear wheel weights

IMPORTANT :

•

Do not overload the tires.

• Add no more weight than indicated in the chart.

2.2 Liquid ballast in rear tires

A water and calcium chloride solution provides safe

economical ballast. Used properly, it will not

and damage tires, tubes or rims. The addition of calcium chloride is recommended to prevent the water from freezing. Use of this method of weighting the wheels has the full approval of the tire companies. See your tire dealer for this service.
