When we released the original HAHN 250/B, it changed the game for firewood producers who needed a professional-grade processor in a compact, mobile package.

But we didn't stop there. We listened to the operators in the woodyards and the professionals in the field. The result? The HAHN 250/B2. While the original 250/B remains a workhorse, the B2 is a complete evolution designed for those who need to push more wood through the machine with less effort. Here are the five key upgrades that make the B2 the new standard in firewood processing.
HAHN 250/B2
HAHN 250/B
​1.  New Dual Chain Infeed Trough
Handling crooked or slick logs can slow down even the best operator. The B2 replaces the standard infeed with a new dual chain infeed trough. This provides significantly better traction and stability, ensuring that your logs stay on track and consistently move smoothly into the cutting chamber.

2.  Heavier Splitter Beam & New Wedge Design
To handle more pressure and different wedge designs, we’ve reinforced the core of the machine. The B2 features a heavier splitter beam specifically engineered to support our redesigned wedge system with up to a 16-way splitting wedge.

3.  The Power of Choice: 4, 6, 8, 12 & 16-Way Wedges
This is the game-changer. Thanks to the reinforced beam and new design, the B2 can now accommodate 12-way and 16-way splitting wedges, allowing you to split a log into 16 consistent pieces in a single stroke and produce uniform size firewood faster than ever before.

4.  Wider Tip Tray
Efficiency is all about flow. We’ve increased the width of the tip tray on the B2 to better catch and align blocks as they drop from the saw. This wider "landing zone" reduces the chance of jams and ensures that even your largest diameter logs transition smoothly into the splitter.

5.  Wider Dual Chain Outfeed Conveyor
High-volume splitting requires high-volume clearing. To match the speed of the new 16-way wedge, we’ve upgraded the outfeed to a wider dual chain conveyor. This ensures that wood moves away from the splitter quickly and cleanly, preventing bottlenecks and keeping your woodpile growing at record speeds.

The original 250/B is a rugged built machine for those who need a reliable, compact, professional firewood processor.  However, if you are a commercial producer where flexibility & cords-per-hour are the most important metrics on your balance sheet, the HAHN 250/B2 is built for you. With its multitude of standard features & wedge options, it is designed to work as hard as you do.

Below is a comparison showing both machines, including the main differences & standard features on both machines.  The 250/B2 & 400/B are built on the same basic frame, with the splitter beam on the 400/B being a bit stronger to handle the increased splitting force.  Comparisons show standard features on both machines.

The traditional ways of getting both speed & power from a hydraulic cylinder, including 2 stage pumps, multiple pumps, or a regen valve, limit your range of speed & power in comparison to our patent pending Power + Splitting System.  By using 2 or more cylinders of different size, you have a much wider range of speed & power from a single machine, than can be achieved from a traditional 2 stage pump or regenerative valve.

The Power + system gives you a much wider range of capabilities in a single machine.  Blazing fast, sub 2 second cycle times & 40 tons of power, all from a 40 HP machine.
Picture
The examples below use 3” (Small) & 5” (Large) splitter cylinders.

Fast mode powers the small cylinder with 10 tons of splitting force.  The small 3" cylinder extends in 1.1 seconds and returns in .6 seconds for a total of 1.7 second cycle time.

Power mode powers the large cylinder with 30 tons of splitting force.  The large 5" cylinder extends in 3 seconds and the small cylinder still returns the push plate at the same .6 seconds, so the cycle time for the 5" cylinder is 3.6 seconds.

Ultra-Power mode powers both cylinders out and provides 40 tons of splitting force.  The extend time is 4.1 seconds and return is also .6, for a total of 4.7 seconds cycle time in this mode.

All 3 modes have a return time of .6 seconds as the small cylinder always returns the ram, regardless of the split mode (Speed/Power/Ultra-Power)
​
If you’re in the market for a firewood processor but you can’t decide between a fast, european style processor, or a more powerful, but slower processor that’s capable of pushing through a 16-way wedge, now you don’t have to choose.  The Patent Pending HAHN Power + Splitting System gives you the best of both worlds in one machine.

Coming soon in our model 400/B
]]><![CDATA[2 Splitting Cylinders Are Better Than 1]]>Thu, 01 Jan 2026 19:16:35 GMThttps://www.hahnmachinery.com/blog/2-splitting-cylinders-are-better-than-1So what’s all the hype about?

How CAN you get 40 tons of splitting power and less than 2 second cycle time from a 40HP class machine?

It’s as easy as 1, 2….  Two splitting cylinders that is.

The patent pending HAHN Power + Splitting System uses 2 cylinders to get the best of both worlds, speed & power, from a single machine. If your log inventory varies in size & species, you know there’s no “one size fits all” machine to efficiently handle both your small & large logs.  At least until now.

Speed mode powers the small cylinder, Power mode powers the large cylinder, and Ultra Power mode powers both cylinders.  Regardless of what mode you’re in, the small/fast cylinder returns the ram for blazing fast return in all modes.  Whether you’re splitting a 5” log into 2 pieces, a 8” log into 4 pieces, or a 16” log into 16 pieces, the Power + system will ensure you’re cycling as fast as possible through each size log.  It’s like getting two machines in one!

We’re hoping to have our first machine ready this spring, with production models available late spring, or early summer.

If you’re thinking of buying a firewood processor in the near future, you may want to wait and see this new machine before making your decision.]]><![CDATA[New Patent Pending Splitting System]]>Fri, 26 Dec 2025 17:21:12 GMThttps://www.hahnmachinery.com/blog/new-patent-pending-splitting-systemThere’s a lot going on at HAHN during this Christmas season.

In addition to introducing our newly updated 250/B2 firewood processor, we are proud to announce that we’ve just submitted a new patent application to the US Patent And Trademark Office.

We are building a revolutionary new firewood processor that will utilize our new patent pending splitting system. The HAHN 400/B firewood processor will have the following features/specs:
  • 40HP class machine
  • Sub 2 second splitter cycle time
  • 40 tons splitting power
  • 2, 4, 6, 8, 12 & 16 way wedge options
  • Efficiently handle both small & large logs with one machine

​In addition to our new splitting system, the 400/B will include all of the standard features from our current HAHN Mini-Pro 250/B2 processor, including 20” diameter log capacity, a hydraulically pivoting conveyor, tip tray, positive log stop, LED lights, oil cooler, hydraulic live deck and much more.

We also plan to incorporate our new patent pending splitting system into a log splitter in early to mid 2026. You’ll get the best of both worlds, the speed of a re-split machine and the power to easily push through a 16-way wedge.

If you’re thinking of buying a firewood processor or log splitter in the near future, you may want to wait and see these new machines before making your decision. They really will be a game changer!
More details coming soon.

Thanks & Merry Christmas!]]>
