Most Common Problems Found in the New Holland BR740

Many possible problems can crop up depending on how the baler is utilized and maintained. However, in the case of an aging New Holand BR740, here are the main problems that usually plague its users:

1. Baler Not Feeding

The New Holland BR740 can experience issues with its baler not feeding properly, leading to a disruption in the process. To diagnose the issue, it is important to look at potential causes and their associated symptoms.

Manual checks should be performed first, as this may reveal an obvious obstruction or malfunctioning part that is preventing the baler from functioning correctly. If manual checks do not yield any results, checking with tools such as a multimeter can be done to further inspect specific parts of the machine.

The common reasons for the baler not feeding include a jammed bale chamber, faulty clutch engagement system, worn flywheel teeth on the drive shaft, damaged chain drive system, blocked feed roller chain sprocket, or broken belt on the pick-up mechanism. If the bale chamber is jammed, it should be cleared and inspected to ensure that nothing can impede its performance.

Meanwhile, the clutch engagement system may need adjustment if it is not engaging properly. If the flywheel teeth on the drive shaft are worn, they should be replaced to restore the baler's functionality. The chain drive system should also be checked for any obstructions or wear and tear that can disrupt its effectiveness. This includes checking for a blocked feed roller chain sprocket or a broken belt on the pick-up mechanism.

2. Straw Breaks

The most common cause of having only straw breaks and no bales in the New Holland BR740 is due to issues with the baler drive system. This can manifest itself through a variety of symptoms, such as difficulty engaging the power take-off (PTO), inability to move drive belts, or even grinding noises while trying to engage the PTO.

These symptoms are often indicative of problems with worn-out bearings, bad sprockets or chains, or other wear and tear on moving parts in the baler drive system.

To properly diagnose the source of this issue requires more than just observation. Manual checks such as checking for visible signs of damage like rust or wear should be done before proceeding further. Likewise, using tools such as a dial indicator or stethoscope can help pinpoint the source of the issue.

Once a symptom has been identified, it is then necessary to identify the parts that need to be replaced to resolve the problem. This often includes replacing bad bearings with new ones and replacing sprockets, chains, and other drive-related components. It is also important to make sure all components are properly sized and tensioned before they are put back into service. Following these steps should restore normal baler operation and allow for bales to be produced again.

3. Knotting Twine

Knotted twine getting stuck in the New Holland BR740 baler is a common problem. To assess its source, symptoms should be identified and manual checks conducted to identify any worn or malfunctioning parts. Furthermore, tools can be used to check the functionality of different components such as belts, pulleys, and shafts.

The most common causes of knotting issues include improper tension on the drive belt, excessively large bales, jammed plunger mechanism, bent guide arms or forks, worn bushings or bearings in rotary components, and misalignment of front-end components. To prevent further damage to the baler due to these knots it is important to address the issue promptly by checking for these potential causes.

In some cases, worn or damaged parts may need to be replaced in order to solve the problem. This could include replacing the drive belt, bearings, bushings, rollers, and/or rotary components. It is also crucial to ensure that all components are correctly aligned and tension levels are adequate for optimal baler performance.

Moreover, checking for loose bolts and nuts can help ensure a secure connection between different baler parts which helps reduce knotting problems.

Knotted twine getting stuck in the New Holland BR740 baler is a common issue that should be addressed promptly to prevent further damage due to excessive strain on various components of the machine.

4. Engine Stalling

Engine stalling issues in the New Holland BR740 baler could be caused by a variety of factors. Many problems can be traced to fuel-related issues, such as dirty fuel, clogged filters or lines, low fuel pressure, and incorrect carburetor adjustment.

Electrical issues are also common causes of engine stalling, including poor spark plug connections, corroded wires and terminals, faulty ignition coils and modules, and weak or dead batteries. Mechanical failures can occur due to worn piston rings or cylinders that need replacing. Excessive vacuum leaks from intake manifold gaskets or hoses can cause the engine to stall when under load as well.

To evaluate the cause of the engine stalling problem with the New Holland BR740 baler, the operator should consult the service manual for proper diagnostic procedures and troubleshooting steps.

The engine should be inspected for visible signs of damage or leakage. Additionally, a full scan with a code scanner can detect any stored codes that may provide insight into the cause of the stalling issue. Further diagnosis can involve performing compression tests or checking various electrical components to verify their operation.

The solution to engine stalling issues with the New Holland BR740 baler will depend on what has been identified as causing the problem. Generally speaking, fuel-related issues are usually solved by cleaning or replacing filters and lines, adjusting carburetors, or changing fuel pressure regulators in order to restore correct levels of fuel delivery to the combustion chambers.

Electrical problems are often traced to worn spark plugs, bad connections, or faulty ignition components that need to be replaced. Mechanical problems should be addressed by replacing any damaged parts and ensuring the engines has proper compression. If a vacuum leak is suspected, all intake gaskets and hoses should be checked for leaks and replaced if necessary.

Once all the necessary repairs have been completed, it may be beneficial to run the engine at idle for several minutes in order to ensure normal operation before continuing use of the baler.

5. Baler Not Starting

The New Holland BR740 baler may fail to start due to a variety of reasons. Among the most common causes are insufficient fuel supply, incorrect spark plug connections, faulty ignition coils or modules, low battery charge, and worn-out starter motor. It is important to diagnose the exact cause of the problem in order to ensure that corrective measures can be taken to restore proper operation.

To troubleshoot starting issues with the New Holland BR740 baler, it is necessary to first check the fuel supply system for any blockages or air leaks that could prevent sufficient fuel from reaching the engine.

Additionally, all electrical components such as spark plugs and wires should be inspected for corrosion or damage that could prevent them from sparking correctly when cranking the engine. The battery should be tested to ensure that it has enough charge, and the starter motor should also be inspected for any signs of wear or damage.

If all of the above issues have been addressed and the engine still fails to start, further diagnostic tests may need to be performed in order to isolate the cause of the problem. A compression test is often recommended in this case as it can pinpoint any mechanical issues such as worn piston rings or cylinders which may be preventing the engine from starting.

Lastly, a scan with a code scanner may reveal any stored codes that could help identify what is causing the issue. Once the cause has been identified and corrected, cranking and starting procedures should then be followed to restore normal operation of the baler.

Recommendation

It is recommended that operators regularly check their balers for any signs of wear or damage as this can reduce the likelihood of mechanical failures occurring in the future and lengthen the usable life of their machinery. With proper maintenance and regular inspections, operators should be able to enjoy long-term productivity from their New Holland BR740 baler.
