About us

For more than 65 years Giltrap Ag has been finding new ways to make farmers’ lives easier, and with the acquisition of Clough Agriculture in 2018, our commitment to innovation in agricultural manufacturing is stronger than ever.

Our design process starts by listening to farmers: what’s working well, and what could be improved? Is there a new way to face an old challenge? Or an old way to face a new one? Farmers answers get us thinking, then these insights develop into design concepts. Prototypes of a new design begin to take shape and they’re refined by testing in the field, to see how theory holds up in practice. In addition to being smart, any innovation has to be pragmatic and dependable also.


Attention to detail

We sweat the small stuff so you won’t have to. Our painstaking diligence means you might not notice many of the design features - because they won’t ever play up. But when you do notice them, it’s for the right reasons.

Bespoke solutions can also be developed for specific issues - a challenge our engineers relish. And all of our machinery has optional add-ons so you can tailor them to your needs.

Commitment to details is what makes Giltrap Ag equipment superior.


Performance engineering

At the manufacturing stage, our fabrication is meticulous. The final result is machinery that is engineered to be durable, reliable & effective.

The hard graft is all worth it when we see farmers getting ahead. Productivity gains are made incrementally - all those little improvements add up. When you’re winning, our time hasn’t been wasted, and neither is yours.
