You’ve seen it at the big box stores or scrolling through equipment sites. It’s a massive, yellow beast that looks like it could crush a boulder. But honestly, most people shopping for a way to clear their woodpile are looking at the 37-ton Champion log splitter and wondering if they actually need that much violence in their driveway.
It’s a fair question.
Most suburban homeowners get by just fine with a 25-ton or even an electric 7-ton unit. But once you move into the territory of seasoned oak, knotted hickory, or those massive rounds of wet elm that seem to laugh at a splitting maul, the math changes. The Champion 37-ton log splitter isn't a toy. It’s a commercial-grade solution for people who deal with "problem wood." If you’re tired of your current splitter stalling or kicking back when it hits a knot, this is where the conversation usually starts.
What’s Actually Under the Hood?
Let’s talk about the engine first because that’s the heart of the whole operation. Champion uses a 338cc single-cylinder OHV engine. It’s a workhorse. It’s not whisper-quiet—none of these machines are—but it’s reliable. One thing you'll notice right away is that it doesn't struggle to turn over if you've maintained it even slightly.
The hydraulic system is the real star, though. We are talking about a massive 2-stage pump that pushes through a 5-inch hydraulic cylinder. That's a lot of fluid moving very fast. In practical terms, that means you have a cycle time of about 16 seconds. Is that the fastest on the market? No. Some 25-ton units are snappier. But speed isn't why you buy a 37-ton machine. You buy it because when that wedge hits a 24-inch wide piece of frozen locust, you want the machine to win.

Most 37-ton Champion log splitter reviews mention the weight. It’s heavy. Nearly 600 pounds. You aren't going to be manhandling this thing into the back of a pickup truck by yourself. It comes with a 2-inch hitch ball coupler for a reason. It’s meant to be towed. Champion rated it for up to 45 mph, though personally, I wouldn't take it on the interstate. Keep it to the backroads and the property trails.
The Vertical vs. Horizontal Debate
This is where the Champion really shines. If you’ve ever tried to lift a 100-pound round of green oak onto a horizontal splitter bed, your lower back probably hurts just thinking about it.
Basically, you pull a pin, and the whole beam swings up into a vertical position. Now, you’re just sliding those massive logs onto the footplate. No lifting. No straining. You just roll the log over, center it, and let the 37 tons of pressure do the heavy lifting. It’s a game-changer for anyone dealing with large-diameter timber.
Some people worry that the vertical mode is less stable. In my experience, as long as you’re on level ground, it’s rock solid. The steel fenders actually help keep the split wood from falling right onto your toes, which is a design detail a lot of cheaper brands skip.
Real World Performance: What Happens When It Hits a Knot?
I’ve seen plenty of splitters "bypass" when they hit a tough knot. The engine bogs down, the hydraulic relief valve screams, and the wedge just stops.
With the 37-ton Champion log splitter, that rarely happens. Because it's a 2-stage pump, the machine automatically shifts into a lower gear (higher pressure, lower speed) when it senses resistance. It’s like a truck shifting into 4-Low to climb a hill. It might slow down for a second, but it just keeps pushing until the wood fibers give up.
- Toughness: It handles 30-inch diameter logs without much fuss.
- Fuel Efficiency: Surprisingly decent. You can usually get through a few cords of wood on a single tank of gas.
- Log Catchers: It comes with these "cradles" that catch the split halves so they don't fall to the ground. This saves you from bending over a thousand times a day. Your spine will thank you.
Maintenance is Not Optional
Don't let the "heavy-duty" label fool you into thinking this machine is indestructible. If you treat it like junk, it’ll behave like junk.
You have to check the hydraulic fluid levels. It takes a lot—usually around 7 gallons of AW32 or universal hydraulic oil. If you let that run low, you’ll cavitate the pump, and that’s a very expensive mistake. Also, the engine oil needs to be changed after the first 5 hours of "break-in" use. Most people skip this, but you’ll see tiny metal shavings in that first oil change that you definitely don't want circulating for another 50 hours.
The air filter is another big one. Log splitting is a dusty, dirty job. If you’re splitting dry wood, the fine dust will clog that filter faster than you think. Pop it out and tap it clean every few days of hard use.
The Competition: Champion vs. LogSplitters.com or NorthStar
Is Champion the best? That depends on what you value.
If you want a Honda engine, you might look at a NorthStar or a Dirty Hand Tools unit, but you're going to pay a premium for that name. Champion’s house-brand engines have become incredibly reliable over the last decade. They aren't the "cheap clones" they used to be back in the early 2000s.
One thing Champion does better than almost anyone is support. If a seal leaks or a valve sticks, you can actually get a human on the phone in North America. They have a massive network of service centers. That matters when you have five cords of wood sitting in your yard and a machine that won't start.
Is 37 Tons Actually Too Much?
Honestly, for 80% of people, yes. It is.
If you are splitting straight-grained pine or small birch, a 37-ton machine is like using a sledgehammer to drive a thumbtack. It’s slower than a smaller machine because the cylinder is larger and takes longer to fill with fluid.
However, if you are a "scavenger" splitter—meaning you get your wood from tree services or city drops—you don't get to choose what you split. You get the gnarly, twisted crotch-wood and the massive trunk rounds that nobody else wanted. In that case, the 37-ton Champion log splitter is the only thing that’s going to get the job done without driving you crazy.
Actionable Steps for New Owners
If you decide to pull the trigger on this machine, don't just pull it out of the box and start ripping.
- Verify the Hydraulic Fluid: Some units ship "dry" or only partially full. Never engage the lever until you’ve confirmed the level on the dipstick.
- Tighten Everything: The vibration from a 338cc engine is intense. After the first two hours of use, take a wrench to the major bolts. You’d be surprised what shakes loose.
- Grease the Beam: Keep a thin layer of grease on the top of the I-beam where the wedge slides. It reduces friction and prevents the steel from galling.
- Use High-Quality Fuel: If you can find ethanol-free gas, use it. Ethanol is the silent killer of small engines that sit in a shed for six months out of the year.
This machine is a beast, but it’s a tool, not a miracle. Respect the power it has, keep your hands away from the wedge, and it’ll likely outlast your desire to ever swing an axe again. Focus on the foundation—level ground, fresh oil, and sharp chains—and the woodpile will disappear faster than you thought possible.
