The first sign of trouble came on a cold morning after Dale had used the International to move grain wagons. Jonah was walking past the machine shed when he noticed a damp mark below the engine. He thought first of an ordinary hose leak, because that was common and easier to correct than almost anything else. But when he wiped the area dry, the moisture returned along a surface that wasn't part of the hose connection.
He crouched beside the engine with a flashlight, tracing the edge of the wet line. Beneath the grime and old paint he found a slender mark in the cast iron, barely more visible than a scratch. A person who had not spent the winter examining discarded engine blocks might have ignored it. Jonah stayed there until his knees ached, studying how the mark curved across the surface and disappeared near a heavy section of the casting.
He told Dale at supper. His father asked whether he had checked the hose clamp and whether the engine had been leaking while running or only after it cooled. Jonah answered each question and admitted that he could not yet be certain of the full extent of the damage. Dale listened, then said he would inspect it himself in daylight.
The next morning Dale tightened a fitting that looked slightly damp. He cleaned the area, ran the engine briefly, and saw nothing alarming. "We'll watch it," he told Jonah, and for a few days the tractor continued working around the yard. Jonah did not argue, but he wrote down what he'd seen, including the location, weather, and the amount of moisture that had collected.
Two days later the fitting was dry and the casting was wet. Jonah called his father out of the grain bin and showed him the difference. Dale stared for a long moment, then fetched a light and inspected the metal himself. The thin line was easier to see now, and a narrow stain extended beyond where it had been earlier in the week.
Neither of them said the word crack immediately. Dale ran a rough thumb along the casting, took a step back, and asked how long Jonah thought the problem had been developing. Jonah said he didn't know and refused to invent an answer just to sound useful. His father put the tools away with unusual care and told him not to start the tractor again until they understood what was happening.
That evening Silas came into the shed with Jonah on one side and Dale on the other. He studied the mark without touching it for a while, looking at the surrounding cast shape and asking about coolant use, operating temperature, and recent work. Dale admitted that he had added coolant twice since the last service and had assumed an aging hose was responsible. Silas said it was too early to know whether the block could be repaired safely, but there was enough evidence to justify a serious examination.
Dale looked at the tractor as though a familiar neighbor had suddenly become ill. He had driven it through storms and harvest dust, repaired it beside frozen roads, and trusted it to finish work that could not wait. The idea of removing its engine was not merely expensive; it meant dismantling a machine that held the family's planting schedule together. Jonah could see the fear beneath his father's anger, and for once he did not interpret the anger as a lack of faith in him.
In the following week the wet line grew longer. The engine began losing enough coolant that Dale shut it down rather than risk additional damage. When the sheet metal was removed and the casting cleaned properly, the fracture looked worse than either father or son had hoped. Dale stood beside the machine in silence, and Jonah opened his notebook to the page where he had recorded the first tiny mark.
The dates showed how the evidence had changed. What began as a doubtful line had become a visible break that nobody could safely ignore. Jonah's first instinct was not triumph at having recognized it early, but regret that he had not persuaded his father to investigate sooner. Silas read the notes and told him that recognizing a problem was useful even when the person responsible for the machine chose a different path.
By then March was ending, and every forecast seemed to move planting season closer. Dale called the parts dealer and several repair shops, asking about the availability of a replacement casting for their old International. The answers varied in price and uncertainty but agreed on one painful fact: locating a suitable part and getting it delivered might take weeks. A newer tractor from Roy's dealership was looking less like an option and more like the only dependable escape.
That night the kitchen table filled with figures again. June wrote down the cost of renting a machine, the possibility of hiring neighboring farmers, and the long-term payments on Roy's replacement tractor. Dale calculated what would happen if the weather offered only a few good planting days before turning wet again. Jonah sat with them until nearly midnight, hearing the quiet strain beneath every number and understanding what his winter's work had been preparing him to face.
Roy arrived the next afternoon carrying a new folder and the expression of a man who believed an unfortunate prediction had been confirmed. He had already called two suppliers and knew that the correct replacement block was not sitting in a warehouse waiting to be shipped. The alternative tractor he had shown Dale was still available, but another farm had asked for an appointment to inspect it. Roy put the figures on the workbench where the damaged International stood with its hood removed.
"I don't enjoy being right about this," Roy told Dale. "But you've got to think about how many acres you're going to cover when the ground finally dries." Dale nodded, because Roy was saying aloud what had kept him awake the previous night. Jonah stood near the tool cabinet, his notebook closed in one hand, trying to find a moment to speak without sounding like a child interrupting adults.
Roy pointed to the engine. "You could spend good money trying to save that casting and still have a tractor that fails halfway through the first field." He wasn't exaggerating, and that made Jonah's response more difficult. The boy waited until Roy had finished, then told his father that he wanted to inspect the block properly before anyone decided whether it could be repaired. Dale asked whether Jonah understood that there might be no second chance if they lost time on an unsuccessful attempt.
"I understand," Jonah said. Dale looked toward Silas, who had been listening from his stool. His father did not jump in with reassurance, and the absence of it surprised everyone. Silas said that the work was possible only if careful inspection showed the surrounding metal remained suitable, and that the same examination might tell them to stop before a single repair began.
