They Told Her a 1956 Mack B-61 Had No Business at a Modern Pull — The Crowd Went Silent at 200 Feet
4,200 people paid $8 a piece to stand in the August heat at the Harlan County Fairgrounds in Loyal, Kentucky on the third Saturday of that month in 2019. And the general consensus among most of them, formed within about 30 seconds of her pulling into the staging area, was that Darlene Fugate had made a mistake coming here.
Not a cruel consensus, not a mean-spirited one, just the kind of collective judgment that forms when a crowd of people who know something about trucks looks at a truck and arrives at the same conclusion simultaneously, the way a room full of carpenters would all notice a crooked door frame without saying a word to each other about it.
The truck was a 1956 Mack B61. She’d driven it 61 miles from her property outside Harlan on Route 119, which tells you something about the truck right there, that it made that drive without incident, without a trailer, under its own power, in August heat. But the crowd didn’t know that part yet.
What they saw was rust the color of old blood on the lower cab corners, a hood that had been repainted somewhere in the late 1970s, and had since developed its own relationship with the sun, and a stack that had been replaced at some point with a straight pipe that ran up the passenger side at a slight angle, as though installed by someone who understood function and had made his peace with the cosmetic result.
The cab sat high on the frame the way B61s do, the way all the old Macks do, with that particular bulldog posture that looks proud from a distance and work and worn up close. She’d paid $4,800 for it 11 years before, from an estate sale outside Pineville, and she had not painted it. Across the staging area, backed in with the precision of a crew that had done this particular maneuver at 47 events in the previous 3 years, was a 2021 Kenworth W900 built by a team out of Lexington with full corporate backing from a regional
fuel distributor and a parts supplier whose logos ran in a neat line across both doors in white vinyl lettering. The build cost was documented in a trade publication at $218,000. The engine was a purpose-built competition Cummins displacing 14 L, fuel injected with custom mapping, and it had won or placed in the top three at every regional event it had entered since its first pull in the spring of 2018.
The crew wore matching shirts. There were four of them. The man who drove it, a 34-year-old named Brady Holt, who had grown up watching his father pull, and had spent the better part of a decade building toward this truck, walked over to look at the B61 the way a surgeon might examine a piece of folk medicine.
He looked at the stack. He looked at the cab corners. He looked at the front axle. He said something to the man standing next to him, and both of them laughed, and it was not a quiet laugh. Darlene Fugate was 58 years old. She was standing at the rear of the B61 with a 9/16 wrench in her right hand, checking the penal hook mount, and she either did not hear the laugh or she did not choose to respond to it.
She tightened the mount a quarter turn, put the wrench in the back pocket of her jeans, and walked up to the cab to check something on the dash. Now, I need to stop here and explain something, because without what I’m about to tell you, the rest of this story is just a woman with an old truck at a competition she shouldn’t have entered, and it is not that story.
It is almost the exact opposite of that story. But first, I need to tell you who Darlene Fugate is, because without knowing who she is, you cannot understand what she was doing in that staging area, and you cannot understand what was about to happen on that strip. Darlene Fugate was born in 1961 in Harlan County, the second of four children of Raymond Fugate, who drove long haul for a regional carrier out of Middlesboro for 31 years, and spent his days off in a garage that he’d poured the slab for himself in 1958, the year before Darlene’s older brother
was born. Raymond Fugate did not talk about trucks the way some men talk about trucks, as a hobby or a passion or an identity. He talked about them the way a farmer talks about soil, as the medium through which work gets done, as something to be understood rather than admired. He had a service manual for every vehicle he’d ever owned, kept in a wooden box on a shelf above the workbench, and he read them the way some men read scripture, not for inspiration, but for precision.
Darlene was in that garage from the time she could walk, not because her father pushed her toward it, but because that was where her father was, and she wanted to be where her father was. By the time she was 12, she could do a valve adjustment on the family’s 1968 International. By the time she was 16, she had rebuilt a carburetor and diagnosed a cracked head on a neighbor’s truck that two mechanics in town had missed.
Raymond Fugate noticed all of this with a quiet satisfaction of a man who has passed something forward without having to say a word about it. She married Harold Fugate in 1984, a man whose last name she already shared by coincidence that entertained the whole county, a man who ran a small excavating operation out of a shop on the same property where they still live.
Harold understood what he was marrying. He built her a second bay on the shop in 1989, poured the slab himself the way her father had taught him, and he has spent 35 years handing her tools and staying out of her way when she’s working, which she considers the finest expression of love she has encountered. They have 140 acres, paid off in 2007.
They have three children, all of whom can change their own brakes, and two of whom can rebuild an engine. They have a dog named Biscuit who sleeps against the engine block of whatever Darlene is working on because the warmth is reliable and the company is good. The B61 came to her in 2008 from the estate of a man named Coy Shepherd, who had used it for 30 years to haul coal from a small private operation he ran on his property outside Pineville.
Coy had maintained it with the same philosophy Raymond Fugate had used. Keep it running, keep it right, don’t worry about how it looks. The truck had 340,000 miles on it when Darlene bought it, which on a Mack B series with a Thermodyne engine means it was approximately halfway through its useful life, because those engines were built in an era when the word overbuilt had not yet been coined because nobody had established the baseline that would make excess measurable.
The engine was a Mack ENDT 673, a six-cylinder two-stroke diesel displacing 673 cubic inches. Mack built that engine from 1953 through the 1970s, and the people who know it know it as one of the most torque-dense engines ever put into a commercial truck. Not the fastest, not the most powerful on paper, but with a torque curve that starts low and builds with a patience that modern engines, chasing horsepower numbers and emissions compliance, have largely abandoned.
She spent 14 months rebuilding it, not restoring, rebuilding. There is a difference that matters here. Restoration is about returning something to how it looked. Rebuilding is about returning something to how it works, and then improving on that within the constraints of the original architecture. Darlene Fugate was not interested in how the B61 looked.
She was interested in what it could do. She did the work in the second bay, mostly alone, mostly in the evenings after Harold had gone in, and the kids had done their homework and Biscuit had settled against whatever warm surface was nearest. She kept a notebook, a yellow legal pad that she dated at the top of each page, recording measurements and clearances and the results of tests the way her father had taught her to, because precision without documentation is just luck, and luck is not a system.
Now, I need to stop here again, because this is the part that Brady Holt and his crew did not know, and it is the intellectual key to everything that happened on that strip in Harlan County on that August afternoon. I need you to stay with me for a few minutes because this is the part that changes the story from a surprise into an inevitability.
When you talk about diesel truck pulling, you’re talking about a contest of traction and torque. The sled behind the truck uses a progressive weight transfer system. As the truck moves forward, the effective weight on the sled increases, which means the resistance increases, which means the truck must produce more and more force to keep moving.
A truck that starts fast and runs out of torque at 150 ft loses to a truck that starts steady and keeps pulling at 250 ft. The question is not how much power your engine makes at its peak. The question is how much torque your engine makes at the bottom of its power band. When the sled is heaviest and the RPMs are dropping and the engine is being asked to do the thing that separates real pulling engines from engines that are merely impressive.
Here’s the thesis, and I want you to hold on to it. Horsepower is what an engine does at high RPM. Torque is what an engine does at low RPM. A high horsepower engine that produces its power at 2,400 revolutions per minute will run out of usable force the moment the load drops the engine below that band. A high torque engine that produces its force at 1,100 revolutions per minute will keep pulling when the high horsepower engine has already stalled because it is still inside its power band, still producing, still moving.
The Mack ENDT 673 in its factory configuration produced 237 horsepower at 2,100 revolutions per minute and 700 ft-lb of torque at 1,200 revolutions per minute. Those numbers were considered conservative when the engine was built, and they were conservative by design. Mack built that engine for logging trucks and heavy haulers and long grade mountain roads, applications where an engine that quit at the bottom of the power band was an engine that got people killed.
They built it to pull from the bottom, to breathe at low RPM, to produce force in the register where force is actually needed. What Darlene did to that engine over 14 months was not dramatic. It was precise. She rebuilt the injectors to a higher delivery rate matched to the engine’s natural fuel curve rather than fighting it. She increased the boost on the Roots type blower, which on a two-stroke Detroit architecture engine like the 673, serves as the scavenging system rather than a pure power adder, and tuning it correctly means the engine breathes
cleaner and burns more completely at low RPM, which is exactly where she needed it. She rebuilt the fuel pump to a higher output, calibrated on the bench with a measuring cup and a notebook and a patience that took four evenings. She did not touch the governor settings in the way that would push the engine toward high RPM power.
She did the opposite. She optimized everything for the 900 to 1,400 revolutions per minute band, the band where the engine was already strongest, and she made it stronger there. The result was an engine that produced, by her own bench measurements, approximately 840 ft-lb of torque at 1,100 revolutions per minute. She wrote that number down on a legal pad page dated March 14th, 2009, circled it once, and did not show it to anyone.
Brady Holt’s Cummins produced 1,100 ft-lb of torque, but it produced that number at 1,600 revolutions per minute. Below that, it fell off. The sled would find that floor. The Kenworth pulled first. Brady Holt staged the truck with the precision of someone who has done this many times, and the Cummins came alive with the sound of a modern competition diesel, which is a particular kind of sound, a tight, wound, purposeful sound that communicates engineering and money, and the very specific confidence of a machine that has been optimized within
an inch of its design limits. The crowd responded to it the way they always respond to that sound, with a forward lean and a tightening of attention because it is a compelling sound, and it deserves respect. The truck moved well from the line, the tires bit and held, and the sled came with it.
And at 100 ft, the crowd was vocal. And at 150 ft, they were louder. And at 180 ft, the engine note changed. A subtle thing, a slight drop in the tight wound quality of the sound, the first sign that the RPMs were finding the bottom of the power band. And at 211 ft, the truck stopped. Not violently, not dramatically. The tires spun once, twice, found nothing, and the truck settled. 211 ft.
The crowd applauded with genuine appreciation. It was a strong pull. It was a serious number. Brady Holt climbed out of the cab, and his crew was around him immediately. And there was the particular satisfaction of a team that has performed well, and the number 211 was in the air, and most of the 4,000 people in those stands considered the competition effectively decided.
It was 2:43 in the afternoon. Darlene Fugate walked to the front of the B61, put her left hand flat on the hood for a moment, the way you touch the shoulder of someone you trust before asking something of them. And then, she walked to the driver’s door and climbed in. There was a boy at the fence line, maybe 9 years old, in a red T-shirt with a tractor logo on it, who’d been standing there since before the Kenworth pulled.
He was watching the B61 with the uncomplicated attention of a child who has not yet learned what he is supposed to dismiss. He had asked his grandfather, who was standing beside him with a thermos of coffee, which truck was going to win. His grandfather had looked at the B61 for a long moment before answering.
He’d said, “I genuinely don’t know, son.” And he’d said it with a tone that suggested he meant it as a compliment to the old Mack, which was more than most of the 4,000 people in those stands were prepared to offer. The B61 started the way the 673 always starts when it’s been properly maintained and properly rebuilt, which is to say, it started with authority.
Not with the tight wound sound of the Cummins, with a different sound entirely, a low, deliberate mechanical sound that has bass in registers the modern engine doesn’t reach, a sound that comes up from the ground rather than descending from the top of the power band, a sound that the older men in the crowd recognized and the younger men in the crowd felt without being able to name.
The straight pipe sent a single pulse of black smoke into the August air, and then cleared to a gray white as the engine found its temperature. And the exhaust note settled into something steady and unhurried that the crowd had not been expecting. There was some laughter in the stands, not universal, but present.
Darlene Fugate staged the truck. She took her time with it, the way she takes her time with everything mechanical, not from hesitation, but from the understanding that proper staging is not a formality, but a function. She set the truck exactly where she wanted it. The official connected the chain and walked clear.
The chain had about 8 in of slack in it. She let the engine settle for a moment. The exhaust note dropped lower, found the 1,100 RPM idle that she had set deliberately, that particular frequency where the 673 is most itself. Then, she let out the clutch. The chain went taut with a single sharp note, a metallic sound that carries across a fairground the way a rifle shot carries, and the B61 moved from the line the way a draft horse moves when it leans into a collar.
Not with drama, not with noise beyond the engine note, which climbed through the low registers with a steadiness that was almost geological, the way a river climbs a bank, the way a mountain breathes. The tires, 11R22.5IS, that she had aired to 90 PSI on the morning of the event. Having checked the weather forecast and the expected temperature, and made a calculation about the clay surface, pressed into the ground without spinning.
They found the surface and they kept it, and the truck moved. At 50 ft, the laughter in the stands had stopped. At 75 ft, the crowd was quiet in the particular way that crowds go quiet when something is happening that they did not anticipate and do not yet have language for. At 100 ft, the engine note had climbed to approximately 1,300 still inside the band she had built it for, and the exhaust had gone from gray-white to a faint blue-gray that told anyone who knew what to look for that the engine was burning clean and
working hard and had not yet reached the ceiling of what it could do. The sled was heavier now. The resistance was climbing. The Cummins had found its floor at this weight. The 673 had not. At 125 ft, Brady Holt, who had been standing with his crew near the staging area, stopped talking. At 150 ft, the crowd began to understand what they were watching, and the understanding moved through the stands the way understanding moves through crowds.
Not all at once, but in a wave, starting from the people nearest the strip who could hear the engine most clearly. Spreading outward to the people in the upper rows who were reading the crowd’s body language and standing up to see what was happening. At 175 ft, the engine note had dropped back to 1,150 revolutions per minute as the sled weight reached its maximum transfer.
And this is the moment that separates the engines that can from the engines that cannot. The 673 did not falter. It did not search. It found the load the way a draft horse finds a plow, not by fighting it, but by leaning into it, by putting weight against weight and letting the geometry of force do its work. The exhaust note deepened.
The tires pressed harder into the clay, and the clay curled up on either side of them in small ridges, the way soil curls behind a plow blade. The frame flexed. The chain vibrated with a frequency you could see from 30 ft away. At 200 ft, the crowd went silent. Not the silence of disinterest, the silence of a crowd that has stopped breathing because breathing would require attention they cannot spare.
200 ft was not the record. 200 ft was not the goal. 200 ft was the number after which the crowd in those stands would remember this pull for the rest of their lives. Because at 200 ft, the B61 was still moving, still pulling, still inside the power band of an engine that Darlene Fugate had rebuilt in a shop outside Harlan by herself over 14 months with a legal pad and a measuring cup and the things her father had taught her, and Brady Holt’s $218,000 Kenworth had stopped 11 ft short of where the old Mack was right now, and
every single person in those stands had done that arithmetic simultaneously. And the result of that arithmetic was the silence. At 218 ft, the crowd found its voice. Not gradually, all at once, the way a dam finds its failure point, not a leak, but a wall of sound that started in the lower stands and hit the upper rows a half second later, and came back as an echo off the metal roof of the equipment barn on the far side of the fairgrounds.
4,200 people who had arrived that afternoon with a consensus about the woman in the old Mack and the old Mack itself were now in the process of revising that consensus at volume. The B61 pulled to 247 ft before the sled resistance finally found the floor of what the 673 could produce at that RPM, and the truck settled with the unhurried dignity of an engine that has been asked to do something it was built to do and has done it completely.
Not a dramatic stop, not a stall, a clean, controlled end to forward motion with the engine still running, still steady, still at 1,100 revolutions per minute idle, as though it had simply decided that 247 ft was enough and had no argument with that decision. 36 ft past Brady Holt’s mark. Darlene Fugate shut the engine down, sat in the cab for a moment, and then climbed out.
She walked to the rear of the truck and checked the pintle hook mount. She walked to the front and checked the tires. She put her hand on the hood. Brady Holt walked over. He took his time getting there, and when he arrived, he stood beside her at the front of the B61 and looked at the engine compartment for a long moment without speaking.
He was a man who understood engines, and he was looking at this one with the attention of someone who is revising an assumption in real time. He said, “What year is that engine?” She said, “’53 design. This one was cast in ’61.” He looked at it a while longer. He said, “What did you do to it?” She said, “Built it for the bottom.
It doesn’t know how to quit down there.” He nodded. He put his hand on the valve cover the way she had put her hand on the hood, and he stood there a moment. Then he said, “I came in here with the wrong tool.” She said, “You came in here with a good tool, just built for a different job.” He nodded again, and he walked back to his crew, and that was the whole of the conversation, and it contained everything that needed to be said.
There was a man in the third row of the stands who had driven 4 hours from Pikeville to watch the pull. His name was Gene Combs, and he was 71 years old, and he had worked on Mack B-series trucks for 30 years as a fleet mechanic before he retired. And he had told his son-in-law on the drive down that he wanted to see the old Mack pull because he had a feeling about it that he couldn’t quite explain, except to say that he knew what those engines were capable of when somebody who knew what they were doing got hold of one.
After the pull, he sat in his seat for a while after the crowd had started moving, and his son-in-law asked him if he was all right, and Gene Combs said he was fine. He just wanted to sit for a minute. He said, “That woman just proved something that I’ve been trying to explain to people for 40 years.” His son-in-law asked what that was.
Gene Combs said that the bottom of the curve is where the work lives. Everybody wants to talk about the top. The top is just noise. Darlene Fugate drove the B61 back to her property outside Harlan that evening on Route 119. She stopped once for fuel at a station outside Baxter, and the man behind the counter asked her what she’d been up to, and she said she’d been to the pull at the fairgrounds. He asked how she did.
She said, “Fine.” She paid for the fuel and drove home. The B61 is still on her property. It still runs. She uses it occasionally to move equipment around the back of the property, and when she does, the sound of the 673 carries across the hollow in a way that her neighbors have described as the most reliable sound in the county.
A sound that means something is being done that needs doing and is being done correctly. The hood still has the same relationship with the sun that it had in Loyal that August. She has not painted it. The legal pad from the rebuild is in the wooden box above the workbench, the same box Raymond Fugate built in 1958. The page dated March 14th, 2009 with the circled number, is still there.
Harold has read it. He has not said anything about it because nothing needs to be said. Biscuit has been replaced by a dog also named Biscuit, as is the custom on their property, who sleeps against the engine block of whatever’s running in the second bay because the warmth is reliable. The ground at the Harlan County Fairgrounds doesn’t remember any of it, of course.
Clay doesn’t keep records. but the people who were there do. The boy in the red shirt is 12 now, and he tells the story to anyone who will listen. And the part he always tells first is not the distance. It’s the sound. He says the old truck sounded like it was thinking, like it was deciding, and then it just did it.
That is the correct description. If you were there that day, or if you know someone who was, or if you know a story like this one, a quiet person with an old machine and piece of knowledge that the crowd couldn’t see, I want to hear it. Put it in the comments below. I read every one of them, and I mean that without qualification, because the stories that come in from the people who watch this channel are the reason this channel exists.
There are more Darlene Fewgates out there than the world currently knows about. And every one of those stories deserves to be told with the care it earned. If you’re new here, what this channel does every week is find one of those stories and tell it completely. The biography, the engineering, the pull, the aftermath, so that the people who did the quiet work get the record they deserve.
Subscribe if that’s the kind of thing you want in your week. It costs you nothing, and it means this work can continue. And if this story hit you the way it hit the people in those stands in Loyal, Kentucky, pass it on to someone who needs it. Not because the numbers need to go up, but because somewhere, right now, there’s a person standing next to something old and worn and rebuilt from the bottom up. And someone is laughing.
And that person needs to know how this kind of story ends. The bottom of the curve is where the work lives. The rest is just noise.
