The Best Firewood Processors Reviewed 2021

If you’re in need of a piece of equipment that will help you cut and split logs into manageable sized firewood, you may benefit from investing in a firewood processor. We looked at some of the very best firewood processors available in 2021 and put our firewood cutting, seasoning, storage ideas and usage expertise to use. Here, we’ve chosen the five best firewood processors available today. If you’re new to firewood, no worries! We also explain what a firewood processor is, what to look for in a firewood processor, and how one works.

What Is a Firewood Processor?

A firewood processor is a piece of equipment made exclusively for cutting and splitting firewood with as little manual labor as possible. Generally, firewood processors consist of four parts: a log deck, saw station, splitting chamber, and outfeed.

Most firewood processors are designed to work with logs up to 12 feet long, though measurements may vary. All you need to do before feeding your logs into the processor is de-limb them.

Firewood processors are used both professionally, for creating stacks upon stacks of firewood for sale, and privately, for splitting a few logs into enough firewood to heat a home all winter.

How Do Firewood Processors Work?

Log deck

The log deck is the part of the firewood processor onto which you feed the logs. This section of the machine is generally made of heavy-duty steel. Log decks usually support hundreds of pounds of weight.

Once logs are placed onto the log deck, they are pulled into the machine by a conveyor belt or similar mechanism by some mechanical help like an excavator or skid steer.

At this point, the logs are ready to pass through onto the saw station and become “rounds” (firewood-length pieces).

Saw station

The saw station of a firewood processor cuts the log into rounds. The process takes a matter of seconds in most cases. Some saw stations cut logs up to 15 or 16 inches in diameter in as little as 5 seconds or less.

Depending on the make and model, saw stations consist of one of three types of saws that cut the logs after being placed on the log deck and pulled into the machine. These are hydraulic chainsaw harvester bars, large slasher saw blades (industrial size circular saw blades), or guillotines powered by hydraulics or PTO from a tractor or an engine.

After the log passes through the saw station, now called a “round,” it moves on to the splitting chamber. Once the round makes it past this next step, it will be correctly sized for firewood use. In guillotine-style firewood processors, the log is split and cut in one step.

Splitting chamber

The second to last stop for logs headed through a firewood processor is the splitting chamber. After the wood has been fed into the machine and cut, it passes through this unit section. Typically, the round is forced to split by being driven into a wedge. Most wedges are designed to split rounds into 2, 4, 6, or 8 pieces. However, some variations split firewood into as many as 16 pieces.

After being split, rounds are now fully processed firewood ready to be loaded, stacked, seasoned, or delivered once they pass through the machine’s final section.

The outfeed is the last stop for logs going through a firewood processor. Most outfeed sections consist of a conveyor belt, or multiple conveyor belts, to carry the wood out and away from the processor.

Where the firewood goes after passing through the outfeed depends on you. If processing firewood for commercial purposes, the wood can be transferred directly to a truck or trailer. On the other hand, if processing firewood for your home, the wood can be sent to a pile for stacking, seasoning, and racking.

A firewood processor’s output capacity can be measured by how many cords of cut and split firewood it puts out per hour. This number ranges between one and five for most machines. It is also a determining factor in the price of a firewood processor.

Best Firewood Processors of 2020

Now that we know what firewood processors do, how they work, and what to look for in one before making a purchase, here are our picks for the best units of 2020. In choosing these particular firewood processors to review, we kept all of the considerations mentioned above in mind and more.

Best Premium Custom Firewood Processor

The Cord King CS Series is readily acknowledged around the world as one of the very best firewood processors for the money. Few units compare to the power and precision the Cord King CS Series provides.

Equipped with a tough carbide-tooth slasher saw (circular saw), the CS Series firewood processors make short work of logs. This firewood series has an industry-leading cut-to-cut time of under 5 seconds. That means you can produce between four and ten full cords of firewood per hour.

Even more, the firewood processors in the CS Series also require less frequent maintenance than other processors in the same category. CS Series saws only need sharpening after producing 1,000 to 1,500 cords of firewood.

    Cord King CS Series firewood processors are available with 50 to 127 HP diesel engines. They also include optional 3 phase electric power or tractor driven PTO. The best part about the CS Series? Cord King will custom-build your unit to be tailored to all of your specific needs.



Best Small Firewood Processor

The HFP160 Firewood Pro is, without doubt, one of the best small firewood processors available in 2020. This mounted fully functioning firewood processor is designed with high production in mind. The machine cuts logs into 20in and 28in rounds and then splits them into 4, 6, or 8 pieces of firewood.

Extremely mobile, this firewood processor allows the operator to easily deposit the finished product into neat piles for stacking and into bins, trucks, trailers, and more. Also, the processor is small and efficient enough only to require a single operator.

Weighing in at 2050lbs, the firewood processor may be smaller than others, but it does not lack any larger machines’ power. The unit measures 52in wide and 43 in high and is feedable with logs up to 16in in diameter.

This processor is designed with skid steer log mounting in mind. However, it can quickly and easily be customized to be compatible with small excavators and wheel loaders.

Best Circular Saw Firewood Processor

Posch’s S-375 is a joystick-controlled high-speed firewood processor equipped with a large 35.4in tungsten tipped slasher-type circular saw. In comparison to older and clunkier firewood processors, the Posch S-375 requires little manual labor to operate.

The machine works with logs up to 14.5in in diameter. After cutting the logs, the unit splits the rounds into your choice of 2, 4, 6, or 8 pieces of firewood. The splitter has a force of 12 tons. The length of finished firewood can be pre-set for up to 19.6in.

The majority of the machine’s functions are all controllable from a joystick. Also, there are half-stroke and only-cut settings for round-production and splitting speeds.

The processor uses two conveyor belts and a hydraulic timber infeed for feeding logs into the machine, transporting the logs through the various cycles, and depositing the finished firewood out and away from the unit.

One of the sweetest parts about these particular firewood processors is that the manufacturer produces several add-ons that increase your overall production with the unit. The add-ons are made possible by external hydraulic ports. Among others, many firewood producers find the powered log table and the PackFix log wrapping machine useful.
