Third run.
The fuel reduction did not reach the best number in Keene’s old notebook.
It did not need to.
Across controlled cycles, XP-2 used between ten and thirteen percent less fuel than its bypass configuration while completing the same load sequence.
Keene sat down.
Michael stared at the monitor.
Daniel smiled.
“It works.”
His father looked at him.
This time, the words carried three decades.
“Yes.”
“It works.”
News spread quickly inside agricultural engineering circles.
Not because XP-2 was about to return to production.
Because lost prototypes rarely resurfaced with original documentation, builders, and functioning systems intact.
Kansas State invited Carter Repair to demonstrate XP-2 at a regional agricultural technology exposition in October.
Michael initially refused.
Daniel accepted on his behalf.
They fought for two days.
Then Michael started fixing cosmetic panels.
That settled it.
The week before the exposition, Carter Repair received another surprise.
A registered letter.
The bankruptcy trustee from the Harlan sale had been contacted by a former Prairie Dynamics investor questioning ownership of intellectual property found inside XP-2.
Daniel panicked.
Michael did not.
“What happens?”
“We call a lawyer.”
“With what money?”
Michael smiled.
“Remember all those new customers?”
A local attorney reviewed the auction terms.
Daniel had purchased the physical machine as-is.
The documents created a more complicated question.
Some intellectual property rights had expired.
Some had been abandoned.
Certain physical engineering records might have belonged to successor entities.
Nobody could simply claim ownership because they wanted them.
The dispute lasted several weeks.
In the end, the documents remained in Daniel’s possession under an agreement allowing archival copies to be provided to former stakeholders and researchers.
No one received a secret billion-dollar patent.
Reality was less dramatic.
Daniel found he preferred reality.
The exposition arrived on a cold October morning.
The field outside Manhattan, Kansas, was packed.
Modern equipment manufacturers had enormous displays.
Autonomous tractors.
Precision sprayers.
Electric utility machines.
Drones.
Sensors.
Software.
XP-2 arrived on a borrowed lowboy wearing its age openly.
Daniel had cleaned the machine.
Repaired the body.
Stabilized the corrosion.
But he deliberately left part of the original faded paint.
The word SCRAP had been preserved beneath clear protective coating on one side.
Michael initially hated that.
“Why would you leave that?”
Daniel smiled.
“Because they wrote it.”
“So?”
“So they were wrong.”
Michael tried not to look proud.
Nearly three hundred people gathered for the demonstration.
Some had been at the bankruptcy auction.
Daniel recognized the equipment dealer who laughed at him.
The man recognized Daniel too.
“You actually got it running.”
“Yeah.”
“How much money did you dump into it?”
Daniel smiled.
“Enough.”
“Worth it?”
He looked toward his father.
“Yeah.”
The man nodded.
No joke this time.
At the edge of the crowd stood the gray-jacket bidder who had pushed Daniel from eight hundred to one thousand dollars.
Daniel approached.
“You cost me two hundred bucks.”
The man laughed.
“I thought you knew something.”
“I barely knew anything.”
“You looked like you knew something.”
“That’s expensive.”
“Auctions usually are.”
They shook hands.
Then Daniel saw Thomas Keene.
The old engineer wore a clean jacket and the same tan cap.
He looked more nervous than Daniel.
“Thought you hated crowds.”
“I do.”
“You started this.”
Keene looked toward XP-2.
“No.”
“I started part of it.”
“You finished it.”
Daniel shook his head.
“We all did.”
At eleven, Professor Porter addressed the crowd.
She explained what XP-2 was.
What it was not.
