The New Holland RB560 round baler is a workhorse on many farms, known for its ability to produce dense, uniform bales of hay, straw, and silage. However, like any complex piece of machinery, the RB560 isn't immune to problems. Understanding common issues, their causes, and potential solutions can save you valuable time and money, especially during the crucial haying season. Let's dive into some of the challenges RB560 owners often face and how to tackle them.
Bale Formation Issues: When Round Isn't Round Enough
One of the most frustrating issues with any round baler is inconsistent bale formation. This can manifest as loosely packed bales, misshapen bales (like "barrel" bales), or bales that simply won't start forming correctly.
Inconsistent Bale Density: Several factors contribute to this. First, check your belt tension. Belts that are too loose will allow the crop to slip, resulting in a loosely packed core. The RB560's belt tensioning system should be regularly inspected and adjusted according to the manufacturer's specifications. Second, consider your ground speed and crop feed rate. If you're driving too fast or feeding too much material, the baler may not be able to properly compress the crop. Slowing down and adjusting your swath width can often resolve this. Finally, examine the pickup teeth for wear or damage. Broken or missing teeth will negatively affect how efficiently the crop is fed into the baler.
Misshapen Bales (Barrel Bales): This usually indicates an uneven distribution of crop within the chamber. This is frequently caused by driving with the pickup offset from the windrow. Ensure you're driving directly over the windrow, feeding the crop evenly across the width of the baler. The bale shape indicators (if equipped) can be helpful in monitoring bale formation and making minor steering adjustments. Also, check the bale density sensors; a malfunctioning sensor can lead to uneven pressure and an oddly shaped bale.
Bale Won't Start: Sometimes, the baler simply refuses to initiate a bale. This can be due to several reasons. Check that the crop is dry enough. Excessively wet hay is difficult to start a bale with. Secondly, ensure the starter roller (if equipped) is functioning correctly. This roller helps initiate the bale core and get the process rolling. Finally, confirm that the net wrap or twine system is properly loaded and functioning. If the baler can't apply the binding material, it won't be able to complete the bale formation process.
Pickup Problems: Getting the Crop Off the Ground
The pickup is the first point of contact between the baler and the crop, so its proper function is crucial.
Crop Wrapping Around the Pickup: This is a common problem, especially in damp conditions or with certain types of hay. Ensure the stripper bars are properly adjusted and clean. These bars prevent the crop from wrapping around the pickup tines. Also, consider using a pickup reel or a crop press if you consistently experience this issue. These attachments help feed the crop more smoothly into the baler.
Broken or Bent Pickup Teeth: This is usually a result of contact with rocks or other debris. Regularly inspect the pickup teeth and replace any that are damaged. Consider using a windrow merger or a rock picker to remove debris from the field before baling.
Pickup Height Adjustment Issues: The pickup height should be adjusted to match the crop conditions. If the pickup is too low, it will dig into the ground and pick up dirt and rocks. If it's too high, it may miss some of the crop. Ensure the pickup height adjustment mechanism is functioning smoothly and that you are adjusting it correctly based on the field conditions.
Net Wrap/Twine Issues: Binding Woes
Problems with the net wrap or twine system can lead to wasted material, poorly secured bales, and downtime.
Net Wrap Not Cutting: This is a frustrating problem that can halt your baling operation. First, ensure the net wrap knife is sharp and properly adjusted. A dull or misaligned knife will struggle to cut the net wrap cleanly. Also, check the net wrap tension. If the tension is too high, the net wrap may tear instead of cutting. Finally, inspect the net wrap brake to ensure it's functioning correctly.
Twine Not Tying: Similar to net wrap issues, problems with twine can prevent the baler from completing the tying process. Ensure the twine arms are moving freely and that the twine knives are sharp. Also, check the twine tension and adjust as needed. Some balers also have sensors that detect twine breakage or empty spools. Make sure these sensors are clean and functioning properly.
Net Wrap/Twine Slipping: This can result in loose bales that fall apart easily. Ensure the net wrap/twine rollers are clean and free of debris. Also, check the tension settings and adjust them as needed. Different types of net wrap and twine may require different tension settings.
Electrical Issues: When the Baler Goes Dark
Electrical problems can range from minor annoyances to complete system failures.
Monitor Not Working: This is often caused by a blown fuse or a loose connection. Check the fuses associated with the monitor and the wiring harness for any signs of damage or corrosion. Also, ensure the monitor is properly calibrated and that the software is up to date.
Sensors Malfunctioning: The RB560 relies on various sensors to monitor bale formation, density, and other parameters. If a sensor malfunctions, it can lead to inaccurate readings and incorrect baler operation. Use a multimeter to test the sensors and replace any that are faulty.
Wiring Problems: Rodents can often damage wiring harnesses, leading to electrical problems. Inspect the wiring harness for any signs of damage and repair or replace as needed. Consider using rodent repellent to prevent future damage.
Hydraulic Issues: Loss of Power
Hydraulic problems can affect various functions of the baler, such as bale ejection, belt tensioning, and pickup height adjustment.
Slow or Weak Hydraulic Functions: This is often caused by a low hydraulic fluid level or a worn hydraulic pump. Check the hydraulic fluid level and add fluid as needed. If the problem persists, have the hydraulic pump inspected and repaired or replaced.
Hydraulic Leaks: Leaks can lead to a loss of hydraulic pressure and inefficient operation. Inspect the hydraulic hoses, fittings, and cylinders for any signs of leaks. Replace any damaged components.
Hydraulic Valve Problems: Malfunctioning hydraulic valves can prevent certain functions from working correctly. Have the hydraulic valves inspected and repaired or replaced by a qualified technician.
General Maintenance: Prevention is Key
Regular maintenance is crucial for preventing problems and extending the life of your RB560.
- Greasing: Regularly grease all grease fittings according to the manufacturer's recommendations. This will help prevent wear and tear on moving parts.
- Chain Lubrication: Keep the chains lubricated to prevent rust and wear.
- Belt Inspection: Regularly inspect the belts for wear, cracks, and damage. Replace belts as needed.
- Tire Pressure: Maintain the correct tire pressure to ensure proper baler operation and prevent tire damage.
- Storage: Store the baler in a dry, sheltered location when not in use. This will help prevent rust and corrosion.
Frequently Asked Questions
- Why is my baler making loose bales? Check your belt tension and ground speed. Loose belts or driving too fast can prevent proper compaction.
- What causes net wrap not to cut properly? A dull net wrap knife or incorrect tension settings are the most common causes.
- Why is my pickup wrapping crop? Ensure your stripper bars are adjusted correctly and consider using a pickup reel.
- What should I do if my monitor isn't working? Check the fuses and wiring harness for any signs of damage or loose connections.
- How often should I grease my baler? Grease all fittings according to the manufacturer’s recommended schedule, typically daily or after a set number of bales.
Conclusion
The New Holland RB560 is a reliable baler, but understanding potential problems and practicing preventative maintenance are key to maximizing its performance and longevity. By addressing issues promptly and maintaining your baler regularly, you can minimize downtime and ensure a smooth and productive haying season.
