• Needle Retention: The dense foliage can clog chipper intakes and reduce airflow, further hindering efficiency.
• Volume: Leylandii hedges often produce a substantial amount of material, requiring efficient processing methods.

These factors combine to make Leylandii a less-than-ideal material for traditional wood chippers. Manually feeding branches into a standard chipper can be time-consuming, physically demanding, and potentially dangerous.

The Crane-Fed Chipper Advantage

Enter the crane-fed chipper. This powerful machine revolutionizes the processing of brashy materials like Leylandii, offering several key advantages:

• Increased Efficiency: The crane allows you to grab large bundles of branches and feed them directly into the chipper, significantly reducing manual handling time.
• Reduced Labor Costs: With a crane-fed chipper, one operator can often handle the entire chipping process, minimizing the need for multiple workers.
• Improved Safety: By eliminating the need to manually feed small branches, the risk of hand injuries is greatly reduced.
• Higher Throughput: The continuous feeding action of the crane allows the chipper to operate at its maximum capacity, resulting in a higher overall throughput.
• Handling Awkward Material: Leylandii often grows into strange shapes, with multiple stems and tangled branches. A crane can easily manipulate these awkward pieces, ensuring they are fed into the chipper efficiently.

For example, I’ve seen operations increase their daily Leylandii processing capacity by as much as 60% by switching from manual feeding to a crane-fed system. The initial investment in the equipment is quickly recouped through increased productivity and reduced labor costs.

Choosing the Right Crane-Fed Chipper

Selecting the right crane-fed chipper is crucial for maximizing efficiency and minimizing downtime. Here are some key factors to consider:

• Chipper Capacity: The chipper’s capacity should be matched to the size and volume of the material you’ll be processing. Consider the maximum diameter of branches the chipper can handle and the horsepower of the engine.
• Crane Reach and Lifting Capacity: The crane’s reach should be sufficient to access the piles of Leylandii you’ll be working with. The lifting capacity should be adequate to handle the weight of the bundles you’ll be lifting.
• Feeding System: Look for a chipper with an aggressive feeding system that can handle the stringy texture of Leylandii. A system with multiple feed rollers and adjustable pressure is ideal.
• Blade Design and Material: The blades are the heart of the chipper. Choose blades made from high-quality steel that can withstand the rigors of processing brashy material. Consider blades with a self-sharpening design to reduce maintenance.
• Safety Features: Ensure the chipper is equipped with essential safety features, such as emergency stop buttons, safety guards, and interlocks to prevent accidental operation.
• Manufacturer Reputation and Support: Choose a reputable manufacturer with a proven track record of producing reliable and durable equipment. Ensure they offer adequate technical support and spare parts availability.

I’ve personally had good experiences with brands like Bandit and Vermeer, known for their robust chippers and excellent customer support. However, it’s essential to research different models and find one that best suits your specific needs and budget.

Optimizing Chipper Performance for Leylandii

Even with the right equipment, optimizing chipper performance for Leylandii requires careful attention to detail. Here are some key strategies I’ve found effective:

Blade Maintenance: The Key to Clean Chips

• Sharpening Frequency: Leylandii’s high moisture content and abrasive nature dull chipper blades quickly. Sharpening the blades more frequently than you would for hardwood is essential. I recommend sharpening after every 4-6 hours of continuous use, depending on the condition of the material.
• Sharpening Technique: Use a high-quality grinding wheel and follow the manufacturer’s instructions carefully. Maintain the original blade angle and avoid overheating the steel, which can weaken it.
• Blade Alignment: Proper blade alignment is crucial for consistent chip quality and reduced vibration. Use a dial indicator to check alignment and make adjustments as needed.
• Blade Replacement: Even with regular sharpening, blades will eventually wear out. Replace them when they become too thin or damaged. Using worn blades can lead to poor chip quality and increased fuel consumption.

A study by the Forest Products Laboratory found that dull chipper blades can reduce chipping efficiency by as much as 20% and increase fuel consumption by 15%. Investing in proper blade maintenance is a small price to pay for improved performance and reduced operating costs.

Feeding Techniques: Mastering the Art of the Crane

• Strategic Stacking: Stack the Leylandii in a way that allows easy access for the crane. Orient the branches with the thicker ends facing the chipper to ensure a consistent feed rate.
• Bundle Size: Experiment with different bundle sizes to find the optimal balance between efficiency and chipper performance. Overloading the chipper can lead to jams, while feeding too little material can reduce throughput.
• Feeding Angle: Adjust the feeding angle to match the chipper’s intake. Feeding the material at an angle that is too steep or too shallow can cause jams and uneven chipping.
• Continuous Feeding: Maintain a continuous flow of material into the chipper to maximize throughput. Avoid stop-and-go feeding, which can reduce efficiency and increase fuel consumption.
• Debris Management: Remove any large debris, such as rocks or metal, from the Leylandii before feeding it into the chipper. These objects can damage the chipper blades and cause serious injury.

I’ve found that using a grapple saw attachment on the crane can be particularly helpful for processing large, tangled Leylandii branches. The saw allows you to cut the branches into manageable pieces before feeding them into the chipper.

Chipper Settings: Fine-Tuning for Leylandii

• Feed Roller Pressure: Adjust the feed roller pressure to match the density and moisture content of the Leylandii. Higher pressure may be needed for wet, dense material, while lower pressure may be sufficient for dry, less dense material.
• Knife Gap: The gap between the chipper knives and the anvil should be adjusted according to the manufacturer’s recommendations. A wider gap may be needed for processing larger branches, while a narrower gap may be more suitable for smaller branches.
• Engine Speed: Operate the chipper at the recommended engine speed for optimal performance. Running the engine at too low a speed can reduce chipping efficiency, while running it at too high a speed can damage the engine.
• Discharge Chute Angle: Adjust the discharge chute angle to direct the chips to the desired location. Avoid directing the chips into areas where they could create a hazard or interfere with operations.

Regularly inspect the chipper for any signs of wear or damage and make repairs as needed. A well-maintained chipper will operate more efficiently and safely.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including:
  • Safety Glasses or Face Shield: To protect your eyes from flying debris.
  • Hearing Protection: To protect your ears from the loud noise of the chipper.
  • Gloves: To protect your hands from cuts and abrasions.
