The last day before the holidays at De Vries Cornjum always has two sides. On the one hand, the yard buzzes with activity: the final frame for our new machine type is still being welded and carefully finished, parts are neatly returned to the shelves, and the first machines are already loaded and ready to go. Meanwhile, the polished vans and trucks wait patiently in line, as if catching their breath after a busy spring.
On the other hand, you feel a quiet sense of satisfaction everywhere. After a season full of wrenching, planning, test runs, and the first meters in the field, it’s now time to pause for a moment. The frames of our new machine type have been sent to the powder coater and will return after the holidays in a fresh, solid finish. Our fleet stands clean and ready in the yard, set to head back into the fields soon. The schedule for the upcoming mowing season is already largely in place, so we can hit the ground running.
This afternoon, everyone heads home briefly to freshen up before gathering around 18:00 at the long tables for the barbecue. It's more than just a fun closing moment; it's when big stories are shared, new plans are born, and successes are celebrated. There’s laughter, reflection, and looking ahead — with a soda or beer in hand and a pride you can almost touch.
As an extra thank you, our regular field staff will receive a De Vries travel trolley this year. Not because we have to, but because we know how important it is to carry your things properly, especially when you’re away from home for weeks in places you'd otherwise never go.
Tomorrow, the first colleagues head off for their well-deserved holidays. We’ll be closed for three weeks and ready again on Monday 4 August — as always, early, but full of energy and eager to get going together.
At De Vries Cornjum, you don’t just work with impressive machines. You help build something bigger: a team that keeps each other sharp, makes progress together, and ends the day at the barbecue together. Thank you to everyone who makes this possible — and who knows, maybe next year you’ll join us at the table.
Since June 2025, Sijbren Bakker (almost 28) has been part of our team. A down-to-earth, calm guy from Winsum — although he’s rarely there. Most of the time you’ll find him at his girlfriend Bianca’s place, in the chalet behind her parents’ house. Or he’s out on his motorcycle, clearing his head after a busy day.

Arnold Terpstra sets down his coffee, leans forward slightly and looks you straight in the eye. “It’s not about me,” he says. Yet he’s the one who can tell the story like no other. A story of movement, of staying curious, and of working together on something bigger than any one of us alone.

Although the bird nesting season is still ongoing in many areas, we have already started mowing the first plots of natural land for 2025. And this is early – even by our standards. Such an exceptionally early start is only possible after thorough ecological assessment and explicit clearance by the client.

At De Vries Cornjum BV, flexibility is in our DNA. Even outside the traditional reed season, we do not hesitate to load our equipment and head to Denmark to harvest a field of miscanthus.

With the breeding season approaching, we look back on an intensive, challenging, and successful period. Over the past months, our colleagues have worked with dedication to maintain wetlands, reed fields, and delicate natural areas. From mowing and gathering reeds to transporting bales to our customers – it has been a season full of hard work and craftsmanship.

The reed mowing season is nearing its end, but we are still going full throttle. As the days grow longer, we make the most of every opportunity to get the job done. Fortunately, the weather is on our side, which means we can keep making progress! Tomorrow, we will even be out with three machines at once to harvest as much reed as possible. Long days and busy weeks – but nothing is more rewarding than coming home satisfied after a day in nature.

Last Saturday the delivery of the machine to the customer at our premises. All in all, another satisfied customer and a machine that exceeded expectations. Based on our latest generation Kingfisher tracked tractor, but specifically geared towards reed mowing. Now the final finishing touches before we proceed to deliver and commission the machine.
A few key points in a row:
Thanks in part to our own good transport facilities, we do not shy away from a long drive. At the invitation of a cooperation of several organisations, we travelled last Wednesday 19 October to give a demo of our machine north of Berlin.
A day with a lot of theory and a lot of talking. In Germany, wet nature management is significantly less advanced than here in the Netherlands. That's why it's great that we can show our machine and our concept with a practical demo, and that it works best. Especially compared to other fellow machine builders present. All in all, a successful day of where we can hopefully look forward to some great collaborations.
The reed harvest season has come to an end for us.
