CTM Root Crop Systems

Like many British agricultural engineers, CTM sprung out of the village forge. Charles Thomas Mountain was a blacksmith and farrier in the small hamlet of Harpley, Norfolk who started producing harrows and other implements required by the rise of tractors over horse power. In 1950 Charles built the first sugar beet cleaner loader which led to the establishment of Harpley Engineering and subsequently CTM Root Crop Systems, a family business now managed by Charles’ grandsons: Nigel, Adrian, Andrew and James. For over 60 years they have designed and built highly effective sugar beet cleaner loaders while providing a useful subcontracting service to other machinery manufacturers. But in a competitive market, they have consistently moved forward by innovation, diversification and partnership with international machinery specialists.

Diversification came in 2010 when they applied their unrivalled expertise in soil and stone separation into a new range of potato field de-stoners: Rockstar. Ridgestar field ridgers followed shortly afterwards.

The new Rockstar2 makes its Lamma debut in January. Their new de-stoner offers web and star combination, improved depth control and ‘one push’ button controls.

“From the customer’s point of view, the running costs will be greatly reduced due to the configuration of webs and stars which ensure greater productivity” Explain Potato Machinery Sales Manager Karl Arndt. “ROCKSTAR2 is truly an ‘operator’s machine’”. 

Innovation has included reformatting their cleaner loader to meet the needs of energy crop growers. Their new CTM 9060 energy beet loader is fitted with ‘real time processing’ to eliminate stones or hard objects without costly washing systems which can involve many thousands litres of water and produce industrial waste water further adding to processing costs. 

The unique 'Censor' device incorporates density scanning plates which trigger reject flaps when they detect stones or other hard objects passing over them. These fall through the pneumatically fired reject flaps onto a discharge conveyor.

Partnership has included UK representation the world’s largest manufacturer of self propelled beet machinery: ROPA. The German company’s beet harvesters and ‘Maus’ cleaner loaders are both world leaders for innovation and build quality.

The latest ROPA Tiger 6, the market’s most powerful sugar-beet production harvester debuted at the Agrosalon trade fair where it was awarded a gold medal for innovation.

In 2016 CTM were delighted to welcome Simon Peacock onto the beet machinery sales force. Simon has many years experience of beet harvesting and handling and is also responsible for the promotion of their latest exclusive line: Bergmann Beet Chasers.

The Bergmann’s crab steering enables it to work parallel to the crabbing ROPA on the field. 

A 2m wide 3 stage elevator (as fitted to the ROPA Tiger can comfortably offload the Tiger’s 30 tonne load every time. Clamp time is reduced by heavy duty hydraulics, the Bergmann discharging in around 55 seconds, up to 4 times faster than competitors...without rutting around the clamp.

CTM have evolved over the past 66 years and are ready to meet the future needs of British agriculture.
