A good operator is a true craftsman, not just someone pushing buttons
A chance roadside encounter led Martínez Peck to diagnose and fix a stranded Vassalli 1200 harvester using only his technical knowledge, requiring no spare parts or tools. Older harvesters offer advantages over modern machines: lighter weight allows operation in waterlogged fields where 30-ton combines sink, and skilled operators can achieve superior grain quality.
- Vassalli 1200 harvester from early-to-mid 1990s, broken down on Chaco highway near Campo del Cielo
- Fixed by purging fuel system—no spare parts or tools required
- Modern combines weigh 30+ tons; older harvesters weigh significantly less, allowing operation in waterlogged fields
- Ricardo Martínez Peck worked at Vassalli's Firmat factory during the era the machine was manufactured
Ricardo Martínez Peck, a former Vassalli factory engineer, repaired a broken 1990s combine harvester on a Chaco highway by purging its fuel system, demonstrating the enduring value of older agricultural machinery in challenging field conditions.
Ricardo Martínez Peck was driving through Chaco province with his wife when he spotted a Vassalli 1200 combine harvester sitting idle on the shoulder of the road near Campo del Cielo. The machine had broken down, and a family was standing beside it, stuck. He knew that harvester. He had worked at the Firmat factory in the early 1990s when Vassalli was manufacturing equipment like this one—machines that had once dominated Argentine fields. He pulled over.
The owner's daughter explained the problem: the harvester wouldn't start. No one could figure out why. Martínez Peck walked up to the machine and looked it over. The engine was a Deutz, a classic diesel motor that had become legendary in rural Argentina. He understood immediately what was likely wrong. After years sitting abandoned in a dealer's lot, then recently purchased and being transported from Charata toward Las Nenas in Santiago del Estero, the fuel system had probably accumulated water or taken in air. The solution required no replacement parts, no special tools—just knowledge of the correct procedure. He walked the family through how to purge the diesel system, step by step.
When they finished, the old harvester turned over on what little battery charge remained and roared back to life. The family was amazed. They made it to their destination without further trouble, and days later, the daughter found Martínez Peck on Instagram and sent him a message: "Thank you for helping us on the road with the Vassalli."
Martínez Peck, who now advises agricultural groups and producers, sees something in these older machines that many people dismiss as relics. Yes, they are from the early-to-mid 1990s. Yes, they are old. But they can harvest soy, corn, and wheat just as well as anything built today. The real advantage is weight. A modern combine can exceed 30 tons when fully loaded and operational—heavy enough to sink into soft ground after heavy rains. The Vassalli weighs far less, which means it can work in conditions where newer megamachines simply bog down. In wet years, when the soil is saturated, these lighter machines become invaluable.
There is another advantage, one that speaks to something deeper about how farming has changed. The old harvesters had what was called a second cleaning unit, a winnower that could produce grain so clean it came out nearly ready to bag. But operating that system required skill. The machine had fourteen different adjustments, and a good operator knew what each one did and how to use them in concert. They were, Martínez Peck says, true craftsmen. Modern harvesters have been simplified. Many of those decisions have been handed over to automated systems and artificial intelligence.
He is not opposed to this shift, but he is skeptical of the certainty with which it is being pursued. Artificial intelligence requires data to work from, and that data has to come from the operator. If the data is wrong, the AI solves the problem incorrectly. A skilled veteran operating an old machine can sometimes produce better grain than a newer one, he argues. The difference shows up in sheer capacity—when conditions are truly difficult, when the stakes are high, the newer machines pull ahead. But the notion that AI will solve everything, that human expertise has become obsolete? That, he suggests, is a mistake. A good operator working alongside intelligent systems is unbeatable. Without that human element, the machine is only as smart as the data it has been given.

A Conversa do Hearth Outra perspectiva sobre a história
What made you stop that day? You could have driven past.
I saw the machine and I recognized it. Not just the model—the era. I had built machines like that. When you've spent years understanding how something works, you don't just walk by when you see it broken.
The fuel system purge—that's a simple fix, but only if you know what you're looking for.
Exactly. After years sitting idle, the system takes in air, the fuel collects water. Most people don't know that. They think something is fundamentally wrong. It's not. It's just forgotten how to breathe.
You mentioned those fourteen adjustments on the old cleaning unit. That sounds like a lot of responsibility on one person.
It was. But that's what made a good operator valuable. They understood the machine as a whole system, not just as buttons to push. They could read what the grain was telling them and adjust accordingly.
And modern machines have taken that away?
They've simplified it, yes. Handed it to computers. The computers are fast, but they're only as good as the information they receive. A human operator generates that information through experience and intuition. You can't automate intuition.
Do you think the old machines will come back?
Not as the primary tool. But in difficult years, in wet seasons, when the ground won't hold the weight—yes, they'll be there. They'll do work that the new machines can't. That's not nostalgia. That's just physics.
