Potato & Carrot Grader, Sorter, Sizer

The Haith Lift Roller Grader is a versatile and efficient way to accurately size potatoes, carrots and more.

It features two sets of stainless-steel rollers which are mounted on two heavy-duty chains. The bottom rollers are fixed height and the top rollers travel over a series of adjustable ramps which lift the rollers up to the set height and allow the required size to fall through onto the grade conveyor.

A unique inclined infeed section presents the crop evenly across the machine in the correct orientation which negates the need for additional infeed rollers and allows accurate sizing on the first grade outlet.

The rollers are mechanically friction driven which consistently turn the crop to ensure accurate sizing and rubberised running tracks prevent roller wear.

Haith’s Lift Roller Grader is available in various widths and roller configurations with up to seven grade outlets. They can operate at a capacity ranging from 5 to 50 tonnes per hour and are suitable for a range of crops including potatoes, carrots, parsnips, swede, onions, beetroot and any other round or elongated root vegetables.

Our story began when Geoff Haith, at just 18 years old, started carrying out repairs for local farmers. Through this work, he recognised a need for more efficient, mechanised solutions for washing and grading root vegetables. Combining his engineering expertise with a strong farming background, Geoff went on to design and manufacture innovative machinery for handling carrots, potatoes, and beetroot.

Until recently, the business was led by Geoff’s five sons and daughter, supported by a talented and forward-thinking management team dedicated to ensuring the company’s continued success. Today, Haith employs over 120 people at our UK factory and works with a network of agents worldwide, promoting the Haith brand globally and delivering high-quality installations and satisfied customers across the world.

Over the years, Haith has continued to grow in both size and capability, relocating three times to accommodate expanding operations. This growth has culminated in our current ultra-modern, wholly owned facility in South Yorkshire, featuring approximately 6,000 m² of production space on a six-acre site. The factory is equipped with the latest CNC laser, waterjet, and bending technology, enabling us to maintain the highest standards of precision and quality.

Haith has received numerous awards for machine design and innovation. We are especially proud to have been honoured twice with the UK’s highest business accolade, The Queen’s Award for Enterprise, both in the Innovation category. As the only company in our field to hold this prestigious award, our commitment to continuous innovation and development—helping to keep the UK vegetable industry at the forefront of technology—has been clearly recognised.
