What are Felling Dogs and Why are They Important?

Felling dogs are the toothed metal protrusions located near the base of your chainsaw bar. They serve as a pivot point and leverage tool during cutting operations. To understand their importance, let’s define a couple of key concepts:

Felling: The act of cutting down a tree.
Bucking: Cutting a felled tree into manageable logs.
Limbing: Removing branches from a felled tree.

While seemingly simple, these processes can be dangerous and physically demanding. Felling dogs significantly improve control, reduce strain, and enhance precision in all three. Without them, you’re relying solely on your strength to hold the saw steady and maintain the correct cutting angle, which can lead to fatigue, errors, and potential kickback.

Tip 1: Understanding the Two-Point Contact System

The foundation of effective felling dog use is understanding the two-point contact system. This involves using both the felling dogs and the saw’s chain to create a stable and controlled cutting motion.

How it works:

Initial Placement: Position the felling dogs against the wood before engaging the chain. This provides a secure anchor point.
Pivot and Cut: As you begin cutting, use the felling dogs as a pivot point to smoothly guide the saw through the wood.
Maintain Contact: Keep the felling dogs firmly pressed against the wood throughout the cut. This prevents the saw from bouncing or kicking back.

My experience:

I remember a time when I was felling a large oak without properly using the felling dogs. The saw kept jumping and vibrating, making it difficult to maintain a straight cut. Not only was it exhausting, but it also created a dangerous situation. Once I focused on establishing and maintaining two-point contact, the difference was night and day. The saw felt more stable, the cuts were cleaner, and I was able to work much more efficiently.

Tip 2: Choosing the Right Felling Dog Size

The Husqvarna 572xp typically comes with a standard-sized felling dog, but you can often upgrade to larger or smaller ones depending on your needs. The “right” size depends primarily on the diameter of the trees you’re typically felling.

Small Felling Dogs: Ideal for smaller trees (under 12 inches in diameter) and limbing operations. They offer greater maneuverability and precision in tight spaces.
Standard Felling Dogs: A good all-around choice for trees in the 12-24 inch diameter range. They provide a balance of leverage and control.
Large Felling Dogs: Best suited for large trees (over 24 inches in diameter). They offer maximum leverage and stability, making it easier to control the saw when cutting through thick wood.

Data and Insights:

In my own experience, using larger felling dogs on bigger trees reduces cutting time by approximately 15-20% and significantly lowers the risk of kickback. I have also noticed reduced wear and tear on the chain because the saw maintains a more consistent cutting angle.

Example:

I was recently working on a project clearing a plot of land overgrown with poplar trees ranging from 8 to 30 inches in diameter. I started with the standard felling dogs, but quickly realized I needed more leverage for the larger trees. Switching to a larger set of dogs made a noticeable difference in the saw’s stability and cutting efficiency.

Tip 3: Mastering Different Cutting Techniques with Felling Dogs

Felling dogs are not just for straight cuts. They can be used effectively in a variety of cutting techniques, including:

Boring Cuts: Used for felling large trees to relieve tension and control the direction of the fall. Involves plunging the saw nose into the tree. The felling dogs provide a stable anchor point, allowing you to carefully control the depth and angle of the cut.
Hinge Cuts: A critical part of felling, creating a “hinge” of wood that guides the tree’s fall. The felling dogs help maintain the correct cutting angle and prevent the saw from binding.
Slab Cuts: Used for milling logs into lumber. The felling dogs provide a stable platform for making long, straight cuts.

Case Study:

I once had to fell a leaning oak tree that was threatening a nearby building. The tree was heavily stressed, and I knew that a standard felling technique could be dangerous. I used a combination of boring cuts and hinge cuts, relying heavily on the felling dogs to maintain control and guide the tree away from the building. The felling dogs enabled me to make precise, controlled cuts, ensuring the tree fell exactly where I wanted it to.

Step-by-step example of boring cut:

Make a standard face cut, ensuring the notch is at the desired direction of fall.
Position the felling dogs firmly against the tree, slightly above the notch.
Carefully plunge the nose of the saw into the tree, using the felling dogs as a pivot point.
Maintain a consistent cutting angle and depth, using the felling dogs to prevent the saw from binding.
Once the desired depth is reached, carefully withdraw the saw and complete the back cut, leaving the hinge intact.

Tip 4: Maintaining Your Felling Dogs

Like any tool, felling dogs require regular maintenance to ensure optimal performance.

Sharpening: The teeth of the felling dogs can become dull over time, especially if they come into contact with rocks or dirt. Use a file or grinder to sharpen them regularly. A sharp set of felling dogs will grip the wood more effectively, providing better control and stability.
Cleaning: Keep the felling dogs free from debris, such as sawdust and sap. Use a wire brush or scraper to remove any buildup.
Tightening: Check the bolts that secure the felling dogs to the saw body regularly. Loose felling dogs can be dangerous and reduce cutting efficiency. Use a wrench to tighten them as needed.
Replacement: If the felling dogs become damaged or worn beyond repair, replace them immediately. Worn felling dogs can compromise safety and reduce cutting performance.

Cost Analysis:

A new set of felling dogs for a Husqvarna 572xp typically costs between $20 and $50. The cost of sharpening tools (files, grinders) can range from $10 to $100, depending on the quality and type of tools you choose. Regular maintenance, including sharpening and cleaning, can extend the lifespan of your felling dogs and save you money in the long run.

Wear appropriate safety gear: Always wear a helmet, eye protection, hearing protection, gloves, and chainsaw chaps when operating a chainsaw.
Maintain a safe working distance: Keep bystanders at least two tree lengths away from the cutting area.
Be aware of your surroundings: Scan the area for hazards, such as power lines, fences, and other obstacles.
Plan your escape route: Before felling a tree, identify a clear escape route in case the tree falls in an unexpected direction.
Never work alone: Always work with a partner who can provide assistance in case of an emergency.
Understand the wood: Knowing if the wood is green wood (freshly cut) or seasoned wood (dried) is crucial. Green wood is heavier and more prone to binding, while seasoned wood is lighter and easier to cut. The moisture content also affects the cutting process. A moisture meter can help you determine the moisture content of the wood. The ideal moisture content for firewood is typically below 20%.
Consider the wood type: Different wood types have different densities and cutting characteristics. For example, hardwoods like oak and maple are denser and require more power to cut than softwoods like pine and fir. Adjust your cutting technique accordingly.

Personal Story:

I once witnessed a near-fatal accident when a tree fell unexpectedly and struck a logger who was not paying attention to his surroundings. Thankfully, he was wearing a helmet and chaps, which likely saved his life. This incident reinforced the importance of always being vigilant and following safety protocols.

Safety statistics:

According to the Occupational Safety and Health Administration (OSHA), chainsaw-related injuries are a significant concern in the logging industry. Common injuries include cuts, lacerations, and fractures. Proper training and the use of safety equipment can significantly reduce the risk of these injuries.
