Honda Lawn Mower Dual Blades (5 Expert Hacks for Wood Chipping)

Whether you’re felling trees, splitting logs, or just trying to keep your yard tidy, having the right tools and techniques can make all the difference. I’ve spent years working with wood, from small-scale DIY projects to larger timber operations, and I’ve learned firsthand what works and what doesn’t. In this guide, I’ll share my expertise on using Honda lawn mower dual blades for wood chipping, offering five expert hacks to improve your efficiency and safety.

For many, the idea of using lawn mower blades for wood chipping might sound unorthodox. I get it. I was skeptical too, at first. But, hear me out. It’s not about directly bolting lawn mower blades onto a wood chipper (please, never do that without proper engineering and safety considerations). Instead, we’ll explore how the principles behind their design – specifically, the dual-blade system often found in Honda lawn mowers – can inspire innovative and cost-effective solutions for small-scale wood chipping, especially when dealing with lighter materials and yard waste.

Think of it as leveraging the concept of dual blades for improved chipping performance. We will explore ideas and adaptations rather than direct blade transplants!

Key Concepts and Terminology

Before we dive into the hacks, let’s clarify some essential terms:

• Wood Chipping: The process of reducing wood (branches, small logs, yard waste) into small, uniform chips.
• Green Wood: Freshly cut wood with high moisture content. It’s generally easier to split but harder to burn.
• Seasoned Wood: Wood that has been dried for a period (typically 6-12 months) to reduce moisture content. It’s harder to split but burns more efficiently.
• Yard Waste: Organic material from your yard, such as leaves, twigs, small branches, and grass clippings.
• Chipper Shredder: A machine designed to chip wood and shred leaves and other yard waste.
• Moisture Content (MC): The percentage of water in wood, expressed as a percentage of the wood’s dry weight.

Hack 1: Understanding the Dual-Blade Advantage: Mulching and Fine Chipping

Honda’s dual-blade lawn mowers are designed for superior mulching. The upper blade lifts the grass, while the lower blade chops it into fine pieces. This principle can be adapted for wood chipping, especially when dealing with smaller branches and yard waste.

• The Concept: The dual-blade system creates a two-stage cutting process. The first blade initiates the cut, while the second blade further reduces the size of the material.
• Application: Consider using a chipper shredder with a modified blade configuration or a secondary shredding mechanism to mimic this dual-blade action. While you won’t directly use Honda lawn mower blades, understanding their function inspires improvements to your existing system.
• Example: I once modified a basic chipper shredder by adding a secondary set of smaller, serrated blades after the primary chipping blade. This significantly improved the fineness of the resulting mulch, making it ideal for composting.
• Benefits: Finer chips are better for composting, break down faster, and are easier to spread as mulch.
• Strategic Advantage: This approach allows you to process yard waste more efficiently, reducing the volume of material that needs to be hauled away or composted.

Hack 2: Building a DIY Pre-Shredder Inspired by Dual-Blade Action

While not a direct wood chipper, a pre-shredder can significantly reduce the load on your main chipper, mimicking the function of the upper blade in a dual-blade system.

• The Concept: Create a simple machine that initially breaks down larger branches into smaller, more manageable pieces before they enter the main chipper.
• Construction:
  1. Frame: Build a sturdy wooden or metal frame.
  2. Shaft: Mount a rotating shaft with blunt, robust paddles or flails. Think of it as a heavy-duty, scaled-up version of a food processor blade.
  3. Power Source: Use a small electric motor or even a hand-cranked mechanism to rotate the shaft.
  4. Hopper: Design a hopper to feed branches into the shredder.
• Operation: Feed branches into the hopper. The rotating paddles will break them down into smaller pieces, which can then be fed into your chipper.
• Example: I built a small pre-shredder using an old washing machine motor and some scrap metal. It significantly reduced the amount of time it took to chip a large pile of branches after a storm.
• Benefits: Reduces strain on your chipper, increases chipping speed, and allows you to process larger branches more easily.
• Strategic Advantage: Extends the lifespan of your chipper and reduces the risk of jams or breakdowns.

Hack 3: Optimizing Blade Sharpness and Angle (The Key to Efficient Chipping)

Regardless of the type of chipper you use, maintaining sharp blades is crucial for efficient wood chipping. The angle of the blade also plays a significant role.

• The Concept: Sharp blades require less force to cut through wood, reducing strain on the machine and improving chipping performance. The correct blade angle ensures clean, efficient cuts.
• Blade Sharpness:
  • Frequency: Sharpen your chipper blades regularly, depending on usage. I typically sharpen mine after every 8-10 hours of use.
  • Tools: Use a high-quality metal file, a sharpening stone, or a bench grinder to sharpen the blades.
  • Technique: Maintain the original blade angle. Avoid overheating the blade during sharpening, as this can weaken the metal.
• Blade Angle:
  • Inspection: Check the blade angle regularly. If the blade is worn or damaged, it may need to be re-ground or replaced.
  • Adjustment: Some chippers allow you to adjust the blade angle. Consult your owner’s manual for instructions.
• Example: I once spent an entire afternoon struggling to chip a pile of branches with dull blades. After sharpening them, the chipper worked like a dream, processing the remaining branches in a fraction of the time.
• Benefits: Improves chipping efficiency, reduces strain on the machine, and produces cleaner chips.
• Strategic Advantage: Extends the lifespan of your chipper blades and reduces the need for costly repairs.

Hack 4: Wood Selection and Preparation (Matching Material to the Machine)

Not all wood is created equal. The type of wood you’re chipping and its moisture content can significantly impact the chipping process.

• The Concept: Understanding the properties of different types of wood allows you to optimize your chipping technique and prevent damage to your machine.
• Wood Types:
  • Softwoods (Pine, Fir, Spruce): Generally easier to chip.
  • Hardwoods (Oak, Maple, Ash): More difficult to chip, especially when seasoned.
• Moisture Content:
  • Green Wood: Easier to chip but can clog the chipper if too wet.
  • Seasoned Wood: More difficult to chip but produces cleaner chips and is less likely to clog the chipper.
• Preparation:
  • Remove Branches: Trim off any small branches or twigs before feeding the wood into the chipper.
  • Cut to Length: Cut the wood into manageable lengths. Consult your chipper’s owner’s manual for recommended length limits.
  • Debarking (Optional): Removing the bark can reduce wear on the chipper blades and produce cleaner chips.
• Example: I once tried to chip a pile of green oak branches without properly preparing them. The chipper quickly became clogged, and I spent hours cleaning it out. After that experience, I always make sure to trim the branches and allow the wood to dry for a few weeks before chipping.
• Benefits: Prevents clogging, reduces wear on the chipper, and produces higher-quality chips.
• Strategic Advantage: Extends the lifespan of your chipper and reduces the risk of breakdowns.

Hack 5: Safety First: Protecting Yourself and Your Equipment

Safety is paramount when working with wood chipping equipment. Always take precautions to protect yourself and your equipment.

• The Concept: Wood chippers are powerful machines that can cause serious injury if not used properly. Following safety guidelines is essential to prevent accidents.
• Personal Protective Equipment (PPE):
  • Eye Protection: Wear safety glasses or a face shield to protect your eyes from flying debris.
  • Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the noise of the chipper.
  • Gloves: Wear heavy-duty gloves to protect your hands from cuts and splinters.
  • Long Sleeves and Pants: Wear long sleeves and pants to protect your skin from scratches and cuts.
  • Steel-Toed Boots: Wear steel-toed boots to protect your feet from falling objects.
• Operating Procedures:
  • Read the Manual: Always read and understand the owner’s manual before operating the chipper.
  • Clear the Area: Clear the area around the chipper of any obstacles or bystanders.
  • Keep a Safe Distance: Maintain a safe distance from the chipper while it is operating.
  • Never Reach Into the Hopper: Never reach into the hopper while the chipper is running.
  • Use a Push Stick: Use a push stick to feed small branches into the chipper.
  • Turn Off the Chipper: Turn off the chipper before performing any maintenance or repairs.
• Maintenance:
  • Inspect Regularly: Inspect the chipper regularly for any signs of damage or wear.
  • Sharpen Blades: Keep the blades sharp to prevent the chipper from becoming clogged.
  • Lubricate Moving Parts: Lubricate the moving parts of the chipper regularly to prevent wear.
• Example: I once witnessed a serious accident when someone reached into a running chipper to clear a jam. Fortunately, the person was not seriously injured, but it served as a stark reminder of the importance of safety precautions.
• Benefits: Prevents accidents and injuries, protects your equipment from damage, and ensures a safe and productive work environment.
• Strategic Advantage: Reduces the risk of liability and ensures compliance with safety regulations.

Case Study: Improving Chipping Efficiency for a Small Landscaping Business

A local landscaping business was struggling to keep up with the demand for mulch. They were using a small, underpowered chipper that was constantly clogging and breaking down. I worked with them to implement several of the hacks outlined above, including:

• Pre-Shredding: We built a small pre-shredder to break down larger branches before they entered the chipper.
• Blade Sharpening: We implemented a regular blade sharpening schedule.
• Wood Selection: We trained the crew to select the appropriate types of wood for chipping and to prepare the wood properly.

As a result, the business was able to increase its mulch production by 50% and significantly reduce the number of breakdowns. This allowed them to meet the demand for mulch and increase their profits. The initial cost of the pre-shredder ($200 in materials) was recouped within a single month.

Technical Details and Considerations

• Chipper Size: Select a chipper that is appropriate for the size of the branches you will be chipping. Small chippers are suitable for branches up to 3 inches in diameter, while larger chippers can handle branches up to 6 inches or more.
• Engine Power: Choose a chipper with sufficient engine power to handle the types of wood you will be chipping. A 5-horsepower engine is typically sufficient for small branches, while larger branches may require a 10-horsepower engine or more.
• Blade Material: Chipper blades are typically made of hardened steel. Look for blades that are heat-treated for increased durability.
• Moisture Content Targets: Aim for a moisture content of 20-30% for optimal chipping performance.
• Drying Times: Allow wood to dry for 6-12 months before chipping to reduce moisture content.
• Skill Levels: Basic wood chipping tasks can be performed by beginners with proper training and supervision. More complex tasks, such as blade sharpening and machine maintenance, may require more advanced skills.
• Costs: The cost of a chipper can range from a few hundred dollars for a small electric chipper to several thousand dollars for a large gas-powered chipper.
