New Holland Br740 Problems

The New Holland BR740 round baler, known for its reliability and ability to produce dense, uniform bales, is a workhorse on many farms. However, like any complex piece of machinery, it's not immune to problems. Understanding these potential issues, and how to address them, can save you valuable time and money during the crucial haying season. This article dives into the common challenges faced by BR740 owners, offering insights and solutions to keep your baler running smoothly.

It All Starts with Understanding Your BR740

Before we jump into specific problems, let's acknowledge the BR740's strengths. It's a robust machine designed for high-volume hay production. Its auto-wrap feature, adjustable bale density, and relatively simple design contribute to its popularity. Recognizing its capabilities allows you to better diagnose when something is amiss. Familiarize yourself with the operator's manual; it's your first line of defense when troubleshooting. Knowing the machine's normal operating sounds, pressures, and speeds will help you quickly identify deviations. Regular maintenance is key to preventing many problems before they even start.

Uh Oh, My Bale Won't Start! What's Going On?

One of the most frustrating issues with any round baler, including the BR740, is the inability to start a bale. Several factors can contribute to this:

Insufficient Hay Intake: This is the most common culprit. If the windrows are too small, or the ground speed is too fast, the baler won't receive enough material to initiate a bale. Slow down, adjust your windrow size if possible, and ensure the pickup teeth are properly adjusted to gather all the hay.
Slipping Pickup: The pickup reel is responsible for lifting the hay off the ground and feeding it into the baler. If it's slipping, it won't be able to deliver enough material. Check the pickup drive belt for wear and proper tension. Also, inspect the pickup teeth for damage or excessive wear. Replace worn teeth promptly.
Moisture Content: Hay that's too dry or too wet can be difficult to bale. Extremely dry hay tends to shatter and blow away, making it hard to form a core. Overly wet hay is heavy and sticky, preventing proper bale formation and potentially causing plugging. Aim for the ideal moisture content for your region and hay type. Using a moisture tester can save you a lot of headaches.
Belt Issues: The belts are essential for turning the hay and forming the bale. Worn, stretched, or damaged belts can slip or fail to grip the hay properly. Inspect the belts regularly for cracks, fraying, or excessive wear. Maintain proper belt tension according to the operator's manual.
Plugged Bale Chamber: If the bale chamber is already partially full of hay due to a previous plugging issue, it can be difficult to start a new bale. Clear the chamber completely before attempting to start another bale.

My Bales Are Coming Out Loose and Uneven!

Another common complaint is the production of loose, poorly shaped bales. This often points to problems with bale density or hay distribution:

Incorrect Bale Density Settings: The BR740 allows you to adjust the bale density to match the type of hay and your desired bale weight. If the density is set too low, the bales will be loose. Increase the density setting gradually until you achieve the desired firmness. Consult the operator's manual for recommended settings.
Uneven Windrows: If the windrows are uneven in size or density, the baler will struggle to distribute the hay evenly across the bale. This can result in bales that are lopsided or have soft spots. Try to create uniform windrows with consistent density.
Worn Bale Tension Springs: The bale tension springs apply pressure to the belts, which in turn controls the bale density. Over time, these springs can weaken or break, resulting in loose bales. Inspect the springs for damage and replace them if necessary.
Faulty Hydraulic System: The hydraulic system controls the tension on the belts and the overall bale density. If there's a leak or a problem with the hydraulic pump or cylinders, it can affect the bale density. Check the hydraulic fluid level and inspect the system for leaks. Consult a qualified mechanic for hydraulic repairs.
Sticking Bale Shape Indicators: The bale shape indicators can sometimes stick, leading to improper hay distribution. Ensure these indicators are moving freely and are properly lubricated.

The Dreaded Plug: Clearing Those Hay Jams

Plugging is an inevitable part of baling, but frequent plugging can be a sign of a problem. Here's what to look for:

Overfeeding: Trying to bale too much hay at once can overwhelm the baler and cause a plug. Reduce your ground speed and allow the baler to process the hay at a manageable rate.
Wet Hay: As mentioned earlier, wet hay is a major cause of plugging. Avoid baling hay that's too wet. If you must bale slightly damp hay, reduce your ground speed and bale smaller bales.
Poor Pickup Adjustment: If the pickup teeth are not properly adjusted, they may not be feeding the hay evenly into the baler, leading to a plug. Adjust the pickup teeth according to the operator's manual.
Foreign Objects: Rocks, sticks, and other debris can get caught in the baler and cause a plug. Carefully inspect the windrows for foreign objects before baling.
Belt Slippage (Again!): Slipping belts can cause hay to accumulate in the wrong areas, leading to plugging. Ensure the belts are properly tensioned and in good condition.

When clearing a plug, always disengage the PTO and shut off the tractor before attempting to remove the obstruction. Use caution and wear gloves to protect your hands.

Net Wrap Nightmares: Tying Troubles

The automatic net wrap system is a great time-saver, but it can also be a source of frustration if it malfunctions. Here's how to troubleshoot common net wrap problems:

Incorrect Net Wrap Tension: If the net wrap is too loose, it won't properly secure the bale. If it's too tight, it can break or cause the bale to distort. Adjust the net wrap tension according to the operator's manual.
Improper Net Wrap Loading: Make sure the net wrap roll is loaded correctly and that the net is feeding smoothly through the system. Follow the instructions in the operator's manual.
Worn Net Wrap Knives: The knives that cut the net wrap can become dull or damaged over time, leading to incomplete cuts or frayed edges. Replace the knives as needed.
Sensor Malfunctions: The net wrap system relies on sensors to detect when the bale is ready for wrapping. If these sensors are dirty or malfunctioning, the system may not operate correctly. Clean the sensors regularly and inspect them for damage.
Hydraulic Issues (Yes, Again!): The net wrap system is often hydraulically powered. Low hydraulic pressure or a faulty cylinder can prevent the system from working properly. Check the hydraulic fluid level and inspect the system for leaks.

Keeping the BR740 Healthy: Preventative Maintenance is Key

As mentioned earlier, preventative maintenance is crucial for keeping your BR740 running smoothly. Here are some key maintenance tasks:

Greasing: Grease all the grease fittings regularly, as specified in the operator's manual. This will help to prevent wear and tear on moving parts.
Oiling Chains: Keep the chains properly oiled to prevent rust and ensure smooth operation.
Checking Belts: Inspect the belts regularly for wear, cracks, and proper tension. Replace worn belts promptly.
Sharpening Knives: Keep the knives sharp to ensure clean cuts and efficient operation.
Checking Bearings: Inspect the bearings for wear and replace them as needed.
Hydraulic System Maintenance: Check the hydraulic fluid level regularly and inspect the system for leaks. Change the hydraulic fluid and filter as recommended by the manufacturer.
Tire Pressure: Maintain proper tire pressure for optimal performance and safety.
Storage: When storing the baler for the off-season, clean it thoroughly, lubricate all moving parts, and store it in a dry place.
