BUHLER VERSATILE 2375 (01) PDF Document

Before operating your BUHLER VERSATILE 2375, you should be thoroughly familiar with the location and operation of all controls. Perform all daily lubrication and maintenance operations as outlined. After completing daily maintenance, perform a walk-around visual inspection, paying particular attention to the following items:

• Fan belt for cracks

• Engine area for accumulation of debris

• Hoses, lines, and fittings for leaks or damage

• Tires for damage

• Hardware for looseness

• Driveline and hydraulic pump areas for leaks or debris accumulation

• Ensure the tractor is ballasted properly for the work to be performed.

• Check dual or triple wheel mounting bolt torque.

Make any necessary repairs before using the tractor.

To start the engine on your BUHLER VERSATILE 2375, follow these steps:

1. Fasten your seat belt.

2. Put the transmission in neutral.

3. On tractors equipped with a PTO, put the switch to the “OFF” position. A safety switch on PTO-equipped models permits engine starting only when the PTO is off.

4. Engage the park brake. A safety switch in the park brake will not permit the tractor to start unless the park brake is engaged.

5. Check to be sure that the remote hydraulic levers are in the neutral position.

6. On tractors equipped with a 3-point hitch, make sure that the hitch controls are set to the lowest position.

7. Set the engine throttle to the lowest position.

8. Turn the ignition to “RUN” to activate the electrical accessories. Observe the warning lamps to be sure they are functioning.

9. Turn the ignition to the “START” position to crank the engine, and release when the engine starts. The switch has a starter protection feature; if you release the key to “RUN” and the engine doesn’t start, you must turn it back to “STOP” before trying again.

10. Once the engine has started, allow it to idle and warm up before adding a working load.

IMPORTANT: To prevent starter motor damage, never crank the engine for more than 30 seconds. If the engine does not start within 30 seconds, wait 2 minutes to cool the starter motor before recranking.

For cold-weather starting on your BUHLER VERSATILE 2375, follow the normal engine starting steps 1 through 10, then proceed as follows:

11. If the engine does not start within 15 seconds of cranking, depress the cold start switch for two seconds while the engine is cranking and release to inject starting fluid. If the engine does not start after 15 more seconds, release the ignition switch. Allow the starter motor to cool down for two minutes, and repeat the procedure.

12. If, after the engine starts, it runs roughly at low idle with an ambient temperature below 0° C (32° F), it is permissible to press the cold start button again to inject an additional amount of starting fluid to aid in engine warm-up.

IMPORTANT: Use only one starting fluid charge per engine crank cycle of 30 seconds. Never hold the button longer than 5 seconds, as damage to the electric solenoid valve may result. Use a maximum of three injections for initial start-up and warm-up.

NOTE: The cold start system injects a 4.8 cc metered shot of fluid with each depression of the switch. A temperature sensor prevents fluid injection if the engine temperature is above 27° C (80° F). If the engine fails to start after three attempts, use a block heater or other means to warm the engine.

1. The block heater cord is located on the right side of the engine.

2. A 3-wire 15-amp extension cord is required to connect the block heater to a grounded 115-volt electrical outlet.

3. To operate the heater, plug the heater cord in for at least four hours before attempting to start. Maximum starting ability is usually obtained within four hours.

4. Disconnect the cord when the engine has started.

WARNING: To avoid shocks or other injuries, never use an ungrounded or inadequate extension cord. Always use a grounded 3-wire extension cord with a 3-wire plug rated for at least a 15-ampere load, and protected by a suitable fuse or circuit breaker. Be sure cords are properly grounded; do not handle if wet. Do not plug the heater in if not immersed in coolant as it may overheat and burst, causing injury.

1. Set the park brake, put the transmission in neutral, and turn the PTO clutch control and all accessories OFF.

2. Attach one end of the positive booster cable to the positive terminal of the booster batteries and the other end of the same cable to the positive terminal of the center battery on the tractor.

3. Attach one end of the negative cable to the negative terminal of the booster battery, and the other end of the same cable to a ground on the tractor frame at least 305 mm (12″) from the discharged batteries. DO NOT CONNECT TO THE NEGATIVE POST OF THE DISCHARGED BATTERIES.

4. Be sure that the clamps from one cable do not touch the clamps of the other cable. Do not lean over the battery when making connections.

5. Start the tractor following normal engine starting procedures.

6. When the tractor starts, remove the booster cables. Disconnect the negative cable first, then the positive cable.

7. If the tractor fails to start, charge the batteries.

SAFETY PRECAUTIONS:

• Wear protective clothing and goggles.

• Do not smoke or expose the battery to open flame.

• Do not connect or disconnect live circuits.

Throttle Operation:

The hand throttle is located on the right console. To increase engine speed, move the lever forward (rabbit). To reduce engine speed, pull the lever backward (turtle). Rated operating speed is 2100 RPM.

Cruise Control Operation:

Cruise control maintains a specified engine RPM. It is controlled by two switches: the “CRUISE/OFF” button and the “+/–(SET)” button.

• Setting Cruise Control: Move the throttle handle higher than the desired cruise setting and press the “CRUISE” button to enter cruise operation. The engine speed will go to the last stored RPM setting. Adjust the setting with the “+/–(SET)” button. The “+/–(SET)” button changes the setting by 10 RPM per momentary push. For best results, set the cruise mode with the throttle lever at Full Throttle.

• Deceleration: Using the decelerator pedal or moving the hand throttle lower than the cruise setting will decrease the cruise RPM. When the pedal is released or the handle is moved forward again, the cruise RPM will return to the set speed.

• Exiting Cruise Mode: Pressing the “OFF” button exits cruise mode and returns the engine to the speed set by the current throttle position.

The electronic system remembers the current cruise control setting even after the cruise switch is turned off, the engine is shut off, or if the batteries are disconnected.

1. Gradually slow down the tractor. Set the throttle as low as possible.

2. Disengage the clutch, apply the brake and put the controls into neutral.

3. Reduce the engine speed to Idle. Run the engine for 3 to 5 minutes before shutdown to allow the engine to cool.

4. Shut down the engine and remove the key. Turn all electrical accessories OFF.

IMPORTANT: If the engine has overheated, allow it to idle for an extended length of time to reduce the temperature. If the temperature does not return to normal or the coolant level warning lamp is ON, shut down the tractor immediately.

The climate controls are located in an overhead panel.

Heater Operation:

1. To activate the heater, open the heater hose valve on the right side of the engine block. In hot weather, shut this valve off to prevent heated coolant from flowing into the heater core.

2. Rotate the temperature control knob counterclockwise (toward red) to increase temperature.

3. Use the pressurizer fan switch to select fan speed (low, high, purge).

4. Use the recirculation knob to control the mix between external and recirculated air.

Air Conditioning Operation:

1. Activate the air conditioning with the two-position rocker switch. An indicator light will glow when it’s on.

2. Rotate the temperature control knob clockwise (toward blue) to decrease temperature.

3. Select the desired fan speed.

4. Use the recirculation knob to control air mix.

Dehumidifying: To dehumidify the cab air during cold weather, use the heater and air conditioner together. Turn the air conditioner on and turn the recirculation knob clockwise to recirculate cab air. Set the temperature control knob to the desired heat level.

Before Operation:

1. Lock the drawbar directly behind the PTO shaft to eliminate swinging.

2. Check for proper clearance of the PTO drivelines, especially when turning.

3. Ensure the implement PTO drive shaft has a 45 mm (1-3/4”) diameter splined shaft (20 spline) yoke designed for 1000 RPM.

4. Check that PTO drive shaft halves have adequate overlap and will not separate when turning.

5. Ensure all shields are in place and in good condition.

PTO Operation Steps:

1. Stop the engine and park the tractor. Connect the drawbar to the implement hitch.

2. Attach the implement drive shaft to the tractor output shaft.

3. Start the tractor with the transmission in neutral and the PTO switch in the off (disengaged) position.

4. With the PTO disengaged, raise and lower the implement to check for proper clearance.

5. With the engine at 1000 RPM, engage the PTO. The switch is a two-motion switch; push down on the center button and lift up on the outer knob. An indicator lamp will light on the warning light bar.

6. Increase engine speed to 2100 RPM for field operation, which will result in a 1000 RPM PTO speed.

7. When making sharp turns, lower the engine RPM, disengage the PTO, and raise the implement if possible.

8. To shut off the PTO, press the PTO knob downward. If the engine is shut off with the PTO switch on, the tractor will not restart until the PTO switch is placed in the off position.

NOTE: The PTO will not engage if the engine speed is greater than 1400 RPM.

The four remote hydraulic control levers are on the right console and are color-coded to match the quick couplers at the rear.

The levers have four positions:

• Neutral: Center position.

• Extend (Raise): Pull the lever toward the operator. An adjustable pressure release detent holds the lever in this position until the cylinder reaches the end of its travel.

• Retract (Lower): Push the lever away from the operator one position. A detent also holds the lever in this position.

• Float: Push the lever to the farthest position away from the operator. This position is used for implements that need to follow the ground contour.

Lockout Levers:

Below each control lever is a lockout lever with three positions:

• Rearward position: Releases the lock and allows full travel to all positions.

• Center position: Prevents the control lever from entering the float position.

• Forward position: Locks the lever in neutral. If engaged while in the retract position, it allows for continuous flow by limiting travel between the float and retract positions.

Flow Control Adjustment:

Each valve spool has a rotary flow control knob. Rotate counterclockwise to increase flow and clockwise to decrease flow. Push the button in the center of the knob to pull it upward or push it downward to change the setting.

Proper ballasting is crucial for achieving maximum tractor efficiency. The goal is to achieve the correct tractor weight, weight distribution (front-to-rear split), and wheel slip.

Basic Rules for Ballasting:

• Wheel Slip: Aim for 8% to 15% wheel slip for drawbar work. Too little slip can increase drivetrain load and soil compaction, while too much slip wastes fuel and time.

• Operating Weight: The recommended operating weight for a BUHLER VERSATILE 2375 is 16,160 kg (35,625 lbs.). This is based on a factor of 43.1 kg (95 lbs.) per engine horsepower.

• Weight Distribution (Field Ready):

– For drawbar applications: 55% on the front axle, 45% on the rear axle.

– For 3-point hitch applications: 65% on the front axle, 35% on the rear axle.

This static distribution is designed to achieve a 50/50 dynamic weight distribution when the implement is under load in the field.

How to Ballast:

1. Weigh the Tractor: Start by weighing your tractor on a scale to get its actual unballasted shipping weight (front and rear axles separately). Do not rely on book values.

2. Calculate Total Ballast Needed: Subtract the tractor’s shipping weight from the recommended operating weight (16,160 kg for a 2375 model) to find the total amount of ballast to add.

3. Calculate Axle Weight Distribution: Multiply the recommended operating weight by the appropriate percentages (55/45 or 65/35) to determine the target weight for each axle.

4. Calculate Ballast per Axle: Subtract the initial axle weights from the target axle weights to find how much ballast to add to the front and rear axles.

5. Add Ballast: Use a combination of cast iron weights (front suitcase, rear wheel weights) and liquid ballast in the tires to achieve the target weights. It is preferable to use as much dry weight as possible before adding liquid ballast.

The correct articulation stop must be used for each tire size to prevent the tires from contacting the fuel tank. The following table lists the approved tire configurations and corresponding maximum articulation angles for the BUHLER VERSATILE 2375.

Note: Any tractor equipped with a PTO option requires a 38° articulation block kit to be installed. If the tire size requires a 33° or 31° kit, use those instead. Triple tires (⊗) can only be mounted when the tractor is equipped with heavy-duty axles.
