How to Use Harley Rake: PTO Power Capabilities Explained (Wood Prep)
Well, folks, it’s been a scorcher lately, hasn’t it? The kind of weather that makes you sweat just thinking about going outside. Ironically, it’s also the kind of weather that makes you think about firewood – because you know those chilly nights are coming, and you’ll want a nice fire crackling in the hearth. And that, my friends, brings us to the Harley Rake.
I’ve spent a good chunk of my life out in the woods, from felling trees to splitting logs, and I’ve learned a thing or two about making the whole process more efficient and less back-breaking.
Let’s dive deep into how to use a Harley Rake, focusing on its PTO power capabilities for wood prep. I’ll share my experiences, shed light on the technical aspects, and give you some practical tips to get the most out of this powerful tool.
Harley Rake for Wood Prep: PTO Power Capabilities Explained
The Harley Rake, also known as a power box rake or landscape rake, isn’t just for landscaping. With the right setup and technique, it can be an invaluable asset for preparing your woodlot for logging, clearing debris, and even leveling ground for wood storage. The PTO is the key to unleashing its full potential.
What is a PTO and Why is it Important?
PTO stands for Power Take-Off. It’s a mechanical system that allows an implement, in this case, the Harley Rake, to draw power directly from the tractor’s engine. Instead of relying on hydraulic power alone, the PTO provides a direct, robust connection for turning the rake’s rotor. This is incredibly important for wood prep because it allows the rake to aggressively till the soil, remove rocks and roots, and level the ground with greater efficiency than hydraulically powered models.
My Experience: I remember the first time I used a PTO-powered Harley Rake. Before that, I was using a hydraulic version, and the difference was night and day. The PTO model chewed through tough roots and compacted soil like it was nothing, while the hydraulic one would often bog down. It saved me hours of work and a lot of frustration.
Understanding PTO Specifications for Harley Rakes
Before you hook up your Harley Rake, it’s crucial to understand the PTO specifications of both your tractor and the rake itself. Mismatched PTO speeds or horsepower ratings can lead to equipment damage or even injury.
- PTO Speed: PTO speed is measured in revolutions per minute (RPM). The most common PTO speeds are 540 RPM and 1000 RPM. Make sure your tractor and Harley Rake are compatible. Running a 540 RPM implement on a 1000 RPM PTO (or vice versa) is a recipe for disaster.
- Horsepower Requirements: Harley Rakes require a certain amount of horsepower to operate effectively. This will vary depending on the size of the rake and the type of material you’re working with. Consult the manufacturer’s specifications for your specific model. Generally, you’ll need at least 30-40 horsepower for a smaller Harley Rake and 50+ horsepower for larger models.
- PTO Shaft Size and Type: PTO shafts come in different sizes and types (e.g., 1 3/8″ 6-spline, 1 3/8″ 21-spline, 1 3/4″ 20-spline). Make sure the PTO shaft on your Harley Rake matches the PTO output shaft on your tractor.
Data Point: According to a study by the American Society of Agricultural and Biological Engineers (ASABE), using the correct PTO speed and horsepower can increase the efficiency of PTO-driven implements by up to 25%.
Technical Requirement: Always use a PTO shaft that is the correct length for your setup. A shaft that is too long can bottom out and cause damage, while a shaft that is too short can disconnect and cause the implement to lose power or even detach.
Preparing Your Woodlot with a Harley Rake
Here’s where the rubber meets the road (or, more accurately, where the rotor meets the dirt). Using a Harley Rake for wood prep involves several key steps:
- Clearing Initial Debris: Before you even think about using the Harley Rake, you need to remove any large debris like fallen trees, large branches, and rocks. This will prevent damage to the rake and make the job much easier. A chainsaw, skid steer, or even a good old-fashioned axe can be helpful here.
- Adjusting Rake Settings: Harley Rakes have several adjustable settings that allow you to customize the rake’s performance. These settings typically include:
- Rotor Depth: This controls how deep the rake tills into the soil. For wood prep, you’ll generally want a moderate depth to remove roots and rocks without disturbing the soil too much.
- Rotor Speed: Some Harley Rakes allow you to adjust the rotor speed independently of the PTO speed. Slower speeds are better for removing rocks and debris, while faster speeds are better for leveling the ground.
- End Plates/Side Shields: These plates control the width of the area that the rake covers. You can adjust them to create a wider or narrower path, depending on your needs.
- Operating the Rake: Once you’ve adjusted the settings, it’s time to start raking. Here are a few tips for operating the Harley Rake effectively:
- Start Slow: Begin by driving slowly and gradually increasing your speed as you get a feel for how the rake is performing.
- Overlap Passes: Overlap each pass by about 6-12 inches to ensure that you’re covering the entire area.
- Adjust Depth as Needed: If you’re encountering a lot of rocks or roots, you may need to increase the rotor depth. If the rake is bogging down, you may need to reduce the depth or slow down.
- Be Mindful of Obstacles: Watch out for any hidden obstacles like tree stumps or buried pipes. Hitting one of these can damage the rake or your tractor.
- Collecting Debris: As the Harley Rake tills the soil, it will collect rocks, roots, and other debris. You’ll need to collect this debris periodically and dispose of it properly. A skid steer with a grapple bucket or a tractor with a front-end loader can be very helpful for this task.
Case Study: I once helped a friend clear a heavily wooded area for firewood production. The area was full of rocks, roots, and stumps. Using a PTO-powered Harley Rake, we were able to clear the entire area in just a few days. We then used a skid steer to remove the debris and level the ground. The result was a clean, level area that was perfect for stacking and storing firewood. The key was adjusting the rotor depth and speed to match the conditions, and overlapping our passes to ensure complete coverage.
Leveling Ground for Wood Storage
One of the most valuable uses of a Harley Rake in wood prep is leveling the ground for wood storage. A level surface is essential for stacking firewood properly, preventing it from tipping over and creating a safety hazard. It also promotes better air circulation, which helps the wood dry faster.
- Grading: Use the Harley Rake to grade the area, filling in any low spots and removing any high spots.
- Compacting: After grading, compact the soil with a roller or a tractor to create a firm, stable surface.
- Adding Drainage: If the area is prone to flooding, consider adding drainage to prevent the wood from getting waterlogged. This could involve installing drainage pipes or creating a slight slope to allow water to run off.
Technical Detail: A well-drained wood storage area should have a slope of at least 1% to allow for proper water runoff.
Selecting the Right Harley Rake for Wood Prep
Not all Harley Rakes are created equal. When selecting a Harley Rake for wood prep, consider the following factors:
- Size: Choose a rake that is the right size for your tractor and the area you’ll be working in. A rake that is too small will take longer to cover the area, while a rake that is too large may be too difficult to maneuver.
- Construction Quality: Look for a rake that is made from high-quality materials and is built to withstand the rigors of wood prep. Heavy-duty steel and reinforced welds are essential.
- Adjustability: Choose a rake that has adjustable rotor depth, rotor speed, and end plates. This will allow you to customize the rake’s performance to match the conditions.
- PTO Compatibility: Make sure the rake is compatible with your tractor’s PTO speed and horsepower.
- Weight: A heavier rake will generally be more effective at tilling the soil and removing debris. However, a rake that is too heavy may be difficult to lift and maneuver.
Practical Tip: Before buying a Harley Rake, ask for a demonstration. This will allow you to see the rake in action and get a feel for how it performs.

Wood Selection Criteria for Firewood Production
Once you’ve prepped your woodlot, it’s time to start thinking about the wood itself. The type of wood you choose will have a significant impact on the quality of your firewood.
- Hardwoods vs. Softwoods: Hardwoods like oak, maple, and ash are denser and burn longer than softwoods like pine and fir. Hardwoods also produce more heat and less smoke.
- Moisture Content: The moisture content of the wood is critical. Green wood (freshly cut wood) has a high moisture content and is difficult to burn. It also produces a lot of smoke and creosote, which can be a fire hazard. Seasoned wood (wood that has been dried for at least six months) has a lower moisture content and burns much more efficiently.
- Species: Different species of wood have different burning characteristics. For example, oak is known for its long burn time, while birch is known for its bright flame.
- Size: The size of the logs will affect how easily they burn. Smaller logs will ignite more quickly, while larger logs will burn longer.
Technical Detail: The ideal moisture content for firewood is between 15% and 20%. You can measure the moisture content of wood using a moisture meter.
Data Point: According to the U.S. Department of Energy, burning seasoned wood can reduce emissions by up to 50% compared to burning green wood.
Tool Calibration Standards: Chainsaw Sharpening
A sharp chainsaw is essential for efficient and safe wood processing. Regular chainsaw sharpening is crucial.
- File Size: Use the correct file size for your chainsaw chain. The file size is typically stamped on the chain.
- Filing Angle: Maintain the correct filing angle when sharpening the chain. The correct angle is typically specified in the owner’s manual.
- Depth Gauges: Check the depth gauges regularly and file them down as needed. The depth gauges control how much wood the chain removes with each pass.
- Chain Tension: Maintain the correct chain tension. A chain that is too loose can come off the bar, while a chain that is too tight can overheat and break.
Technical Requirement: A properly sharpened chainsaw should cut straight and produce uniform wood chips.
Wood Drying Tolerances and Techniques
Proper wood drying is essential for producing high-quality firewood.
- Air Drying: The most common method of drying wood is air drying. This involves stacking the wood in a well-ventilated area and allowing it to dry naturally.
- Kiln Drying: Kiln drying is a faster method of drying wood that involves using a kiln to heat the wood and remove the moisture.
- Stacking: Stack the wood in a way that allows for good air circulation. This typically involves stacking the wood in rows with gaps between the rows.
- Covering: Cover the wood with a tarp to protect it from rain and snow. However, make sure to leave the sides open to allow for air circulation.
Data Point: Air drying wood typically takes 6-12 months, depending on the species of wood, the climate, and the stacking method.
Technical Detail: The rate of wood drying is affected by temperature, humidity, and air velocity.
Measuring Log Dimensions and Cord Volumes
Accurately measuring log dimensions and cord volumes is important for pricing and selling firewood.
- Log Diameter: Measure the diameter of the log at the small end.
- Log Length: Measure the length of the log.
- Cord Volume: A cord is a unit of measurement for firewood that is equal to 128 cubic feet. A standard cord is typically stacked 4 feet high, 4 feet wide, and 8 feet long.
- Face Cord: A face cord (also known as a rick or a pile) is a stack of firewood that is 4 feet high and 8 feet long, but the width can vary.
Technical Requirement: When measuring cord volume, make sure the wood is tightly stacked to avoid air gaps.
Material Specifications: Wood Moisture Content
Maintaining the correct wood moisture content is critical for efficient burning and reducing emissions.
- Green Wood: Green wood typically has a moisture content of 50% or higher.
- Seasoned Wood: Seasoned wood typically has a moisture content of 15% to 20%.
- Moisture Meter: Use a moisture meter to accurately measure the moisture content of wood.
Practical Tip: Split firewood dries faster than unsplit logs.
Wood Strength and Drying Tolerances
Understanding wood strength and drying tolerances is important for selecting the right wood for different applications.
- Wood Strength: Different species of wood have different strength characteristics. For example, oak is stronger than pine.
- Drying Tolerances: Some species of wood are more prone to cracking and warping during drying than others.
Technical Detail: Wood strength is measured in terms of bending strength, compressive strength, and shear strength.
Industry Standards and Forestry Regulations
Always be aware of and comply with industry standards and forestry regulations.
- Logging Regulations: Follow all logging regulations regarding tree harvesting, erosion control, and wildlife protection.
