The 3407 is a 20-ton skid-steer-powered splitter designed around two-way splitting. It removes the need for a separate engine and reservoir, and its production potential depends heavily on the carrier’s hydraulic flow, pressure and material-handling workflow.

1. Two-way splitting changes cylinder utilization
The core Split-Fire design keeps the knife working in both directions. Instead of treating return travel as dead time, the operator can position the next round and split again as the cylinder moves back.
That design is most valuable when material staging keeps pace with the machine. If the operator spends the cycle walking for the next log, the theoretical advantage disappears. Tables, a log lift or loader support can therefore have a direct effect on realized output.
2. Hydraulic flow controls speed
The 3407 is not a self-contained splitter. Cycle speed depends on the skid steer’s auxiliary flow. Split-Fire publishes examples showing faster cycles as flow increases, which makes carrier compatibility central to the purchase.
Pressure and flow are different. Pressure determines available force; flow determines speed. A high-flow carrier does not automatically mean the attachment should be run at the maximum setting. Confirm the manufacturer’s permitted range for the exact carrier and couplers.
3. 20 tons and the 4-way wedge
Twenty tons can handle a wide range of firewood, while the interchangeable 4-way wedge can increase output on straight, consistent rounds. A 4-way wedge creates more resistance because the machine is making several splits at once.
Knotty, twisted or oversized wood may be more efficient with the 2-way knife. Commercial operators benefit from treating wedge choice as a productivity setting rather than assuming four-way is always faster.
4. Why a skid steer attachment can simplify a yard
If a skid steer is already handling logs, pallets or finished wood, powering the splitter from the same machine reduces the number of engines and hydraulic systems in the yard. The carrier also provides mobility for moving the attachment between piles.
The tradeoff is that the skid steer is committed to the splitter while it is operating. A business that needs the carrier simultaneously for loading may prefer a self-contained tow-behind splitter.
5. Quick couplers and setup
The base product does not include quick couplers, so buyers should plan the hydraulic connection for their carrier. Coupler size, type, cleanliness and pressure rating affect both performance and reliability.
A partially connected or restrictive coupler can create heat and slow cycle time. Hydraulic compatibility should be confirmed before delivery rather than after the attachment is sitting in the yard.
6. Production options and 36-inch stroke
Split-Fire offers options such as log handling accessories and an extended stroke. Those upgrades should be chosen around the actual log supply. A longer stroke adds flexibility for long rounds but can also add travel time when most pieces are shorter.
For a commercial firewood workflow, measure normal log length and round diameter before selecting options. The goal is to reduce handling, not simply maximize specifications.
7. Who should consider the 3407
The strongest buyer is an operation that already owns a compatible skid steer and wants the attachment integrated into a mechanized firewood process. Farms, tree services and firewood businesses can all fit that profile.
It is less attractive if the only skid steer is needed elsewhere during splitting or if the carrier hydraulic system falls outside the attachment’s requirements.
Pre-Purchase and First-Use Checks
Before ordering a splitter, measure typical round length and diameter, identify the hardest species you process and map how logs will reach the beam. Confirm towing or carrier requirements, hydraulic compatibility where applicable, storage space and whether optional tables, log lifts or wedge configurations would remove a real handling bottleneck. The best configuration is the one that reduces touches around the machine, not the one with the longest option list.
At first use, inspect hydraulic connections, fluid level, guards, control movement, wedge condition, tires or attachment points and all transport locks according to the manufacturer manual. Cycle the machine without a log and establish a baseline for speed, sound and temperature before full production. Record service dates and any option settings. If performance changes later, a baseline helps distinguish normal material variation from a hydraulic or mechanical problem.
Buying Decision: Look Beyond the Headline Specification
A high-capacity number or fast cycle is useful only when it removes a real bottleneck. Before buying, measure the material you process most often, the power source you already own, the distance material travels through the work area and how much operator time is spent preparing or repositioning it. That creates a practical baseline for comparing this machine with alternatives.
Also include ownership factors such as maintenance access, wear parts, documentation, towing or tractor requirements, storage and downtime. For commercial operators, labor saved over hundreds of operating hours can matter more than a modest difference in purchase price. For property owners, buying a machine that is easy to use and correctly sized can be more valuable than maximizing capacity that rarely gets used.
Frequently Asked Questions
Does the 3407 have its own engine?
No. It is powered by the skid steer’s auxiliary hydraulic system.
How much splitting force does it make?
The published specification is 20 tons at 2,900 PSI.
Does it split both directions?
Yes. Two-way splitting is a core design feature.
Are quick couplers included?
The base listing states they are not included.
Can it use a 4-way wedge?
Yes. It supports interchangeable 2-way and 4-way splitting configurations.
