JOHN DEERE 3025D (01) PDF Document

The State of California requires the following two warnings for the JOHN DEERE 3025D tractor:

Proposition 65 Warning for Diesel Engines:

Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.

Warning for Gasoline Engines (if applicable):

The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

To operate your JOHN DEERE 3025D tractor safely, please follow these precautions:

Prepare for Emergencies: Be prepared for a fire. Keep a first aid kit and fire extinguisher handy. Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.

Wear Protective Clothing: Wear close-fitting clothing and appropriate safety equipment. Do not wear radio or music headphones while operating the machine.

Protect Against Noise: Always wear hearing protection, such as earmuffs or earplugs, to protect against loud noises.

Follow Safety Instructions: Carefully read all safety messages in the manual and on the machine. Keep safety signs in good condition and replace them if they are missing or damaged.

Handling Fuel Safely:

1. Handle fuel with care as it is highly flammable. Do not refuel while smoking or near open flames or sparks.

2. Always stop the engine before refueling. Fill the fuel tank outdoors.

3. Prevent fires by keeping the machine clean of accumulated trash, grease, and debris. Always clean up spilled fuel.

4. Never fill a fuel container in a pickup truck with a plastic bed liner. Always place the fuel container on the ground before refueling.

Handling Starting Fluid Safely:

1. Starting fluid is highly flammable. Keep all sparks and flames away when using it. Keep it away from batteries and cables.

2. To prevent accidental discharge, keep the cap on the container when storing it and store it in a cool, protected location.

3. Do not incinerate or puncture a starting fluid container. Do not use starting fluid on an engine equipped with glow plugs or an air intake heater.

In case of a fire, follow these steps:

1. Stop the machine immediately at the first sign of fire (smell of smoke or sight of flames).

2. Get off the machine immediately and move safely away from the fire. Do not return to the machine. Your safety is the number one priority.

3. Call the fire department.

4. If you attempt to use a portable fire extinguisher, do so only for a small fire and ensure your safety first. Keep your back to the wind with an unobstructed escape path.

5. If using an extinguisher, pull the pin, aim low at the base of the fire, squeeze the lever slowly, and sweep the nozzle from side-to-side.

The removal of sulfur in Ultra-Low Sulfur Diesel (ULSD) fuel increases its ability to store a static charge. To avoid a fire or explosion from a static electricity discharge, it is important to ensure that the entire system used to refuel your machine (fuel supply tank, transfer pump, transfer hose, nozzle, etc.) is properly grounded and bonded. Consult with your fuel or fuel system supplier to ensure the delivery system is in compliance with fueling standards for proper grounding and bonding practices.

To avoid crushing injury or death during a rollover:

1. Keep the foldable rollover protective structure (ROPS) in the fully extended and locked position.

2. USE a seat belt when you operate with the ROPS in the fully extended position. To fasten the seat belt: hold the latch, pull the belt across your body, insert the latch into the buckle until it clicks, and tug on the belt to ensure it is secure. Snug the seat belt across your hips.

3. If you must operate with the ROPS folded (e.g., to enter a low building), drive with extreme caution and DO NOT USE a seat belt.

4. Return the ROPS to the raised, fully extended position as soon as the machine is operated under normal conditions.

You can reduce the risk of accidents by following these simple precautions:

General Operation:

1. Use your tractor only for jobs it was designed to perform.

2. Operators must be mentally and physically capable of operating the machine safely.

3. Never operate when distracted, fatigued, or impaired.

4. Make sure that everyone is clear of the machine and work area before starting.

5. Keep hands, feet, and clothing away from power-driven parts.

Driving Concerns:

1. Never get on or off a moving tractor.

2. Never ride on a tractor unless seated on a John Deere approved seat with a seat belt.

3. Keep all shields/guards in place.

4. Reduce speed when turning or applying individual brakes.

5. Couple brake pedals together for road travel.

Towing Loads:

1. Be careful when towing and stopping heavy loads. Stopping distance increases with speed and weight.

2. Hitch towed loads only to approved couplings to avoid rearward upset.

Parking and Leaving the Tractor:

1. Before dismounting, shut off SCVs, disengage PTO, stop the engine, lower implements to the ground, and securely engage the park mechanism.

2. If the tractor is left unattended, remove the key.

3. Leaving the transmission in gear with the engine off will NOT prevent the tractor from moving.

Before moving the JOHN DEERE 3025D, be sure that all persons are clear of the machine path. Turn around and look directly for the best visibility. Use a signal person when backing if your view is obstructed or when in close quarters. Do not rely on a camera to determine if personnel or obstacles are behind the machine.

Follow these guidelines when transporting towed equipment with your JOHN DEERE 3025D:

1. Do not exceed the maximum transport speed specified in the implement’s operator manual. Exceeding this speed can result in loss of control, reduced braking ability, tire failure, or damage to the implement.

2. Implements without brakes: Do not transport at speeds greater than 32 km/h (20 mph).

3. Implements with brakes: If the manufacturer does not specify a maximum speed, do not tow at speeds greater than 40 km/h (25 mph). Weight restrictions also apply based on speed, so consult the manual for specific ratios.

Operating on slopes, uneven terrain, or rough ground requires extra caution to prevent loss-of-control and tip-over accidents. Follow these precautions:

1. Avoid holes, ditches, and obstructions that could cause the tractor to tip.

2. Avoid sharp uphill turns.

3. Driving forward out of a ditch or up a steep slope could cause a rearward tip-over. Back out of these situations if possible.

4. Choose a low ground speed so you will not have to stop or shift while on a slope.

5. Avoid starting, stopping, or turning on a slope. If tires lose traction, disengage the PTO and proceed slowly, straight down the slope.

6. Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.

7. Never drive near the edge of a gully, drop-off, or steep embankment.

If your JOHN DEERE 3025D becomes mired (stuck), follow these steps to free it safely:

1. Attempt to back the tractor out. Unhitch any towed implements.

2. Dig mud from behind the rear wheels.

3. Place boards behind the wheels to provide a solid base and try to back out slowly.

4. If necessary to tow with another unit, use a tow bar or a long chain (a cable is not recommended). Inspect the chain for flaws.

5. Always hitch to the drawbar of the towing unit. Do not hitch to the front pushbar attachment point.

6. Clear the area of people. Apply power smoothly to take up the slack; a sudden pull could snap the towing device.

Follow these practices for safe maintenance:

1. Understand the service procedure before starting work. Keep the area clean and dry.

2. Never lubricate, service, or adjust the machine while it is moving. Disengage all power, lower equipment to the ground, stop the engine, remove the key, and allow the machine to cool.

3. Securely support any machine elements that must be raised for service work.

4. Keep all parts in good condition and properly installed. Fix damage immediately.

5. Disconnect the battery ground cable (-) before making adjustments on electrical systems or welding on the machine.

6. Avoid contact with hot exhaust gases and components. They can reach temperatures hot enough to burn people or ignite materials.

Before working on the JOHN DEERE 3025D, park it safely by following these steps:

1. Lower all equipment to the ground.

2. Stop the engine and remove the key.

3. Disconnect the battery ground strap.

4. Hang a “DO NOT OPERATE” tag in the operator station.

Explosive separation of a tire and rim can cause serious injury or death. Follow these safety precautions:

1. Do not attempt to mount a tire unless you have the proper equipment and experience.

2. Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure.

3. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure, resulting in a tire explosion.

4. When inflating tires, use a clip-on chuck and an extension hose long enough to allow you to stand to one side, NOT in front of or over the tire assembly. Use a safety cage if available.

5. Check wheels for low pressure, cuts, bubbles, damaged rims, or missing lug bolts and nuts.

Escaping fluid under pressure can penetrate the skin, causing serious injury. To avoid this hazard:

1. Relieve pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.

2. Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids.

3. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours, or gangrene may result.

4. Do not disconnect or attempt to repair fuel lines, sensors, or other components between the high-pressure fuel pump and nozzles on engines with a High Pressure Common Rail (HPCR) fuel system. Only technicians familiar with this type of system should perform repairs.

The safety decals on your JOHN DEERE 3025D provide important warnings:

1. ROPS – Rear Implements Decal (AVOID AMPUTATION): Warns that hands or fingers may be pinched between the folded ROPS and rear implements. Do not place hands or fingers near foldable ROPS when implements are raised.

2. PTO Shield Decal (AVOID INJURY FROM PTO): Warns to keep all shields in place and to keep hands, feet, and clothing away from the PTO.

3. Avoid Crushing Decal: Provides instructions for rollover protection. Keep the Rollover Protective Structure fully extended, do not jump if the machine tips, and use the seat belt. When the structure must be down, DO NOT use the seat belt and drive with extra care.

4. Safety Instructions Decal: A comprehensive list of 13 safety rules, including reading the manual, keeping shields in place, hitching loads correctly, keeping riders off, reducing speed, and parking safely.

IMPORTANT: Ensure polarity is correct before making connections. Do not connect the negative booster cable to the machine frame, only to the engine block.

Your JOHN DEERE 3025D is equipped with an emission-compliant engine that cleans and filters the exhaust. The system operates in different modes:

Automatic (AUTO) Exhaust Filter Cleaning:

This is the normal mode of operation. When soot in the exhaust filter reaches a certain level, an automatic cleaning is initiated without any operator intervention. The High Exhaust Temperature Indicator will illuminate during this process. Do not disable this mode unless absolutely necessary.

Disabled Exhaust Filter Cleaning:

If the tractor must be used in a situation not suited for the higher temperatures of filter cleaning, you can press the exhaust filter cleaning disable switch to temporarily disable the system. The LED above the switch will illuminate. If the Exhaust Filter Indicator (restriction) comes on while in disabled mode, you must press the switch again to return to AUTO mode to allow cleaning.

Parked Exhaust Filter Cleaning:

If you disregard indicators and do not allow an automatic cleaning, engine performance will be reduced and a parked cleaning procedure is required. To perform a parked cleaning, the following criteria must be met:

1. Engine at low idle

2. Coolant temperature above 60°C (140°F)

3. Transmission in neutral

4. Park brake engaged

5. PTO turned off

Press and hold the exhaust filter cleaning switch in the parked cleaning position to start the process. During cleaning, the high exhaust temperature indicator and the switch’s LED will illuminate. The process is complete when the LED turns off.

Service Exhaust Filter Cleaning:

If you repeatedly cancel or ignore indicators for a parked cleaning, additional engine power limitations will occur, and the STOP indicator will illuminate. At this point, you must contact your John Deere dealer for a required service cleaning.

To operate the transmission on your JOHN DEERE 3025D:

1. Depress the clutch pedal and stop the tractor before shifting the range shift lever, gearshift lever, or forward-reverse lever.

2. Forward-Reverse Lever: With the tractor at rest, select the desired travel direction (forward or reverse).

3. Range Shift: Select the desired speed range (A or B).

4. Gear (speed) Shift:

1. Select the desired speed (1, 2, 3, or 4).

2. Slowly release the clutch pedal to gradually take up the load.

3. Increase engine speed once shifting is complete.

4. With the tractor in motion, you can change gears by depressing the clutch pedal fully, selecting the desired speed, and slowly releasing the clutch to take up the load.

CAUTION: To prevent transmission damage, DO NOT use the forward-reverse lever on-the-go. The tractor must be at rest.

To stop the JOHN DEERE 3025D tractor:

1. Stop the tractor and place the forward-reverse lever, gear shift lever, and range shift lever in their NEUTRAL positions.

When one wheel starts to lose traction, engage the differential lock by pressing the differential lock pedal down. The tractor wheels must be turning before engaging the lock. If possible, engage the differential lock before entering conditions where tires can slip. The lock will disengage by spring action when traction equalizes. If it does not disengage, depress one brake pedal and then the other.

CAUTION: Do not operate the tractor at high speed or attempt to turn with the differential lock engaged.

IMPORTANT: To prevent drivetrain damage, do not engage the differential lock when one wheel is spinning and the other is at rest.

Use the MFWD for better traction when needed. The front-wheel drive can be engaged and disengaged while the tractor is in motion.

1. To engage: Pull up on the MFWD lever.

2. To disengage: Push the lever back down.

If the lever resists disengagement while towing an implement, the load must first be relieved from the power train. To relieve the load, you can either reduce speed and drive straight for a few feet, or stop the tractor and operate in reverse for a short distance.

IMPORTANT: To extend front tire life, engage MFWD only when needed in the field. Do not engage MFWD when driving on hard surfaces unless necessary.

Engaging the PTO:

1. Sit on the operator seat.

2. Stop the machine if it is in motion.

3. Depress the clutch pedal.

4. Reduce the throttle setting to low idle speed.

5. To engage the PTO at 540 rpm, slide the PTO lever toward the right and then rearward. Set the engine rpm to 2400 rpm for the 3025D model.

6. Release the clutch pedal to begin PTO operation.

Disengaging the PTO:

1. Depress the clutch pedal.

2. To disengage, move the PTO lever to the NEUTRAL position from its engaged position.

IMPORTANT: Use rear-mounted equipment rated for 540 rpm. Do not operate the PTO over the rated rpm mark on the tachometer.

1. Be sure the drawbar does not interfere. Move or remove it if necessary.

2. Back the tractor up to the implement so the hitch points align. Place the transmission in NEUTRAL, stop the engine, and engage the park brake before leaving the seat.

3. Slip the draft links over the implement hitch pins and retain them with quick-lock pins.

4. Attach the center link to the implement top mast.

5. Adjust the center link and lift links as necessary to level the implement.

6. Using the position control lever, slowly lower or raise the implement and check the full range of operation for any interference, binding, or PTO separation.

1. Lower the implement to take its weight off the hitch.

2. Adjust the center link to level the implement from front-to-rear. Unlatch the self-locking spring. Rotate the center link body clockwise to lengthen the link or counterclockwise to shorten it. Be sure to re-latch the self-locking spring.

3. The right-hand lift link is also adjustable to accommodate different tire sizes. To change its length, loosen the nut and rotate the turnbuckle assembly clockwise to shorten or counterclockwise to lengthen, then tighten the nut.

Checking Toe-In:

1. Park the machine on a flat, level surface with the front wheels in the straight-ahead position.

2. Measure the center-to-center distance between the front tires at hub level in front of the axle. Record this measurement and mark the tires.

3. Move the tractor back about 1 m (3 ft) so the mark is at hub level behind the axle. Measure the distance between the tires at the same point again.

4. The difference between the front and rear measurements should be less than 3 mm (1/8 in). If the front measurement is smaller, it is “toe-in.” If the rear is smaller, it is “toe-out.”

Adjusting Toe-In:

1. Loosen the tie rod jam nut on both ball joints.

2. Rotate the tie rod tube clockwise or counterclockwise to adjust the toe-in until it is set to 0–3 mm.

3. Tighten the tie rod jam nut to specification. Do not overtighten.

4. Re-check the toe-in setting and repeat if necessary.

A disabled JOHN DEERE 3025D is best transported on a flatbed carrier. Chain the tractor to the carrier securely. Drive the carrier slowly. IMPORTANT: Seal the exhaust to prevent dirt from entering and damaging the engine.

To tow the JOHN DEERE 3025D tractor:

1. IMPORTANT: NEVER tow the tractor faster than 16 km/h (10 mph). Have an operator steer and brake the tractor.

2. Be sure the transmission-hydraulic system oil is at the full level line on the dipstick.

3. Make sure that the gearshift lever, range shift lever, forward-reverse lever, and PTO lever are in neutral. Also ensure the MFWD lever is disengaged.
