Wood Chippers for Firewood Prep: 5 Pro Tips You Need

Firewood preparation can be a real chore, especially if you’re relying solely on axes and mauls. But what if I told you there’s a way to significantly reduce the effort and waste involved? Wood chippers, often thought of for landscaping, can be surprisingly effective tools for creating kindling, processing small branches, and even supplementing your primary firewood supply. Let’s dive into five essential tips to maximize your wood chipper’s potential for firewood prep.

1. Understanding Your Wood and Chipper Capabilities

Before you start feeding branches into your wood chipper, it’s crucial to understand the type of wood you’re working with and the capabilities of your machine. Not all wood chippers are created equal, and different wood species behave differently when chipped.

Wood Anatomy and Properties: A Quick Primer

Wood is a complex material with varying properties depending on the species, moisture content, and density. Understanding these properties is crucial for efficient chipping and firewood preparation.

Hardwood vs. Softwood: Hardwoods, like oak, maple, and ash, are generally denser and burn longer than softwoods like pine, fir, and spruce. However, softwoods often ignite more easily, making them excellent kindling. When chipping, hardwoods require more power and can be harder on your chipper’s blades. Softwoods, on the other hand, tend to be more fibrous and may require a sharper blade for a clean cut.
Moisture Content: Freshly cut wood, often referred to as “green” wood, has a high moisture content (over 50%). This makes it heavier, harder to ignite, and less efficient for burning. Seasoning wood involves drying it to a moisture content of 20% or less. Chipping green wood can be more challenging as it tends to clog the chipper more easily. Dry wood, while easier to chip, can produce more dust.
Density: Wood density affects both chipping efficiency and burning characteristics. Denser woods require more power to chip but produce more heat when burned. Lighter woods are easier to chip but burn faster.

My Experience: I once tried to chip a pile of freshly cut oak branches with a small electric chipper. The machine struggled, constantly clogging and overheating. I quickly learned that hardwoods, especially when green, require a more powerful chipper. On the other hand, I’ve had great success chipping dry pine branches into kindling with the same machine.

Matching Chipper to Wood Type

Choosing the right wood chipper for your needs is essential. Here’s a breakdown of different chipper types and their suitability for firewood prep:

Electric Chippers: These are typically smaller and less powerful, making them ideal for processing small branches and twigs into kindling. They’re quiet, easy to operate, and require minimal maintenance. However, they’re not suitable for hardwoods or larger branches.
- Data Point: Electric chippers typically handle branches up to 1.5 inches in diameter.
Gas-Powered Chippers: These offer more power and can handle larger branches, including hardwoods. They’re more portable than electric models, making them suitable for working in remote locations. However, they’re louder, require more maintenance, and produce emissions.
- Data Point: Gas-powered chippers can typically handle branches up to 3-4 inches in diameter, depending on the model.
PTO Chippers: These are designed to be attached to a tractor’s power take-off (PTO) and are the most powerful option. They can handle large branches and even small logs, making them suitable for processing significant volumes of wood. However, they require a tractor and are more expensive.
- Data Point: PTO chippers can handle branches up to 6 inches in diameter or more, depending on the model.

Actionable Advice: Before purchasing a wood chipper, consider the type and size of wood you’ll be processing. If you primarily need to create kindling from small branches, an electric chipper may suffice. If you plan to process larger branches and hardwoods, a gas-powered or PTO chipper is a better choice.

Understanding Chipper Mechanics

Wood chippers work by feeding wood into a rotating drum or disc equipped with blades or knives. As the wood is forced against the blades, it’s chipped into smaller pieces. The size and shape of the chips depend on the chipper’s design and blade configuration.

Blade Types: Chipper blades come in various shapes and sizes, each designed for specific tasks. Some blades are designed for chipping green wood, while others are better suited for dry wood. Some blades produce larger chips, while others create finer mulch.
Feed Mechanisms: Wood chippers use different feed mechanisms to draw wood into the blades. Some use gravity, while others use rollers or hydraulic systems. The feed mechanism affects the chipper’s efficiency and the size of wood it can handle.
Safety Features: Wood chippers are powerful machines that can be dangerous if not operated properly. Look for models with safety features like emergency shut-off switches, feed hoppers that prevent hands from reaching the blades, and safety glasses.

Case Study: A local tree service company I know uses a PTO chipper with a hydraulic feed system to process large branches and logs. They’ve found that the hydraulic feed system significantly increases their efficiency and reduces the risk of injury. They also use different blade types depending on the type of wood they’re chipping.

2. Mastering Chipping Techniques for Firewood

Once you understand your wood and chipper, it’s time to master the art of chipping for firewood. Proper technique can significantly improve your efficiency, reduce wear and tear on your machine, and produce the desired results.

Preparing Wood for Chipping

Before feeding wood into your chipper, it’s essential to prepare it properly. This involves removing any debris, cutting branches to the appropriate length, and ensuring the wood is free of metal or other foreign objects.

Removing Debris: Remove any leaves, twigs, or dirt from the wood before chipping. This will prevent clogging and ensure a cleaner chip.
Cutting to Length: Cut branches to a length that’s easy to handle and fits comfortably into the chipper’s feed hopper. Avoid feeding excessively long or short pieces of wood.
Removing Metal: Inspect the wood for any nails, screws, or other metal objects. These can damage the chipper’s blades and pose a safety hazard.

Personalized Story: I once chipped a branch that contained a hidden nail. The nail shattered one of the chipper blades and sent metal fragments flying. Fortunately, I was wearing safety glasses, but it was a close call. Always inspect your wood carefully before chipping!

Optimizing Chipping Angle and Feed Rate

The angle at which you feed wood into the chipper and the rate at which you feed it can significantly affect the quality of the chips and the efficiency of the process.

Chipping Angle: Feed the wood into the chipper at an angle that allows the blades to cut cleanly. Avoid forcing the wood straight in, as this can cause the chipper to jam.
Feed Rate: Feed the wood at a steady rate that allows the chipper to process it efficiently. Avoid overloading the chipper, as this can cause it to stall or overheat.

Unique Insight: Experiment with different chipping angles and feed rates to find what works best for your chipper and the type of wood you’re processing. A slight adjustment can often make a big difference in the quality of the chips and the efficiency of the process.

Producing Different Chip Sizes

The size of the chips you produce depends on your intended use. For kindling, you’ll want smaller, finer chips that ignite easily. For supplementing your firewood supply, you may want larger, chunkier chips that burn longer.

Adjusting Blade Settings: Some wood chippers allow you to adjust the blade settings to control the size of the chips. Consult your chipper’s manual for instructions on how to adjust the blade settings.
Varying Feed Rate: Varying the feed rate can also affect the size of the chips. Feeding the wood more slowly will generally produce smaller chips, while feeding it more quickly will produce larger chips.

Data Point: According to a study by the U.S. Forest Service, smaller wood chips (less than 1 inch) ignite more quickly and burn more efficiently than larger chips (over 2 inches).

3. Seasoning and Storing Wood Chips for Firewood

Once you’ve chipped your wood, the next step is to season and store it properly. Seasoning involves drying the wood to a moisture content of 20% or less, which makes it easier to ignite and burn more efficiently.

Understanding Moisture Content Dynamics

Moisture content is a critical factor in firewood preparation. Green wood, with its high moisture content, is difficult to ignite and produces a lot of smoke. Seasoned wood, on the other hand, ignites easily, burns cleanly, and produces more heat.

The Drying Process: Wood dries through a process called evaporation. Moisture moves from the interior of the wood to the surface, where it evaporates into the air. The rate of drying depends on factors like temperature, humidity, and airflow.
Ideal Moisture Content: The ideal moisture content for firewood is 20% or less. At this moisture content, the wood will ignite easily and burn efficiently.
Measuring Moisture Content: You can measure the moisture content of wood using a moisture meter. These devices are relatively inexpensive and easy to use.

Original Research: I conducted a small experiment to compare the drying rates of different wood chip sizes. I found that smaller chips (less than 1 inch) dried significantly faster than larger chips (over 2 inches). This is because smaller chips have a larger surface area exposed to the air.

Optimizing Seasoning Techniques

There are several techniques you can use to optimize the seasoning process:

Stacking: Stack the wood chips in a way that allows for good airflow. A common method is to stack the chips in rows, leaving gaps between the rows.
Location: Choose a sunny, well-ventilated location for seasoning. Sunlight and wind will help to evaporate moisture from the wood.
Covering: Cover the top of the wood chip pile with a tarp to protect it from rain and snow. However, leave the sides open to allow for airflow.

Practical Tip: Elevate the wood chip pile off the ground using pallets or cinder blocks. This will improve airflow and prevent the wood from absorbing moisture from the ground.

Long-Term Storage Considerations

Once the wood chips are seasoned, it’s important to store them properly to prevent them from reabsorbing moisture.

Covered Storage: Store the seasoned wood chips in a covered area, such as a shed or garage. This will protect them from rain and snow.
Ventilation: Ensure the storage area is well-ventilated to prevent moisture buildup.
Pest Control: Protect the wood chips from pests like insects and rodents. Store them off the ground and consider using pest control measures if necessary.

Real-World Example: A local firewood supplier I know stores their seasoned wood chips in large, covered bins with perforated sides. This allows for good airflow while protecting the chips from the elements and pests.
