#NFDF2014 blog: Can @GeorgeMoateLtd’s Norfolk engineered #Tillerstar help deliver #Sustainable farming?

“It offers major savings, without compromising on the quality of the [seed] bed.” That’s the verdict of just one of the many farmers now using the new George Moate Tillerstar to prepare their fields for planting crops such as potatoes, onions, leeks and carrots. The farmer, Sam Patterson, who grows 145 hectares of potatoes in Lancashire, went on to tell Arable Farming magazine that by removing the need for a de-stoner “we’ve saved at least £245/ha from our establishment costs.”

Norfolk’s thriving engineering sector

Don’t let anyone tell you that engineering in this country is finished. Even here in Norfolk, which many people wrongly think of as a sleepy backwater where everyone is a farmer or retired, we have a thriving engineering and manufacturing sector. As World Class Norfolk reports, there are some 1,000 engineering firms in the county, employing around 10,000 highly skilled people (around 5% of the workforce) and supplying global companies such as Boeing, Airbus, NASA, Toyota and Lockheed.

One of these successful companies is George Moate Limited, run by Lesley Pratt and her husband Richard. It makes the award winning Tillerstar, which is helping to revolutionise the planting of vegetables and root crops. And when I say ‘make’, I don’t mean ‘assemble using imported components’: I mean it manufactures virtually every single part in its factory on the edge of North Walsham – so is an ideal subject for an #NFDF2014 blog.


The roots of a new agricultural revolution

George Moate, a Yorkshire farmer and inventor, was the firm’s founder. Over the years he’d developed various bits of agricultural machinery, including bringing the first hydraulic folding tilling machine to market. Then, in 2011, he exhibited a prototype Tillerstar at the Harrogate Show and suddenly the enquiries started pouring in – leaving George with a hard choice: stick to farming (which he loved) or run a full-scale engineering business; he chose farming.

Lesley, an experienced business woman who’d been looking for a new venture after taking time out to raise a family, bought the patents and set about developing the business. This included making 23 major engineering changes to George’s original designs. She also bought back eight prototype machines and had them upgraded to match the new specifications: “We didn’t want any machines out there with the George Moate brand that didn’t meet our standards,” she explains.

Lesley’s partner (in life and business), Richard, already owned a successful engineering company called PSS Steering & Hydraulics, also based in North Walsham. PSS specialises in manufacturing, designing and re-manufacturing parts for heavy duty vehicles and machines made by the likes of Land Rover, John Deere, and JCB. With a 70 strong team of designers, engineers and machinists, it is ideally equipped to make most of the components for the Tillerstar.

What makes the Tillerstar different?

As Lesley explained to me, there has been a quiet revolution in potato farming over the last 30 years or so. When I helped with potato harvesting, during my summer holidays in the early 80s, we had to pick out the stones and clods as the potatoes were carried up the conveyor belt to the trailer. Then farmers introduced new machinery to de-stone fields before planting, by sifting the stones and dumping them in deep-ploughed trenches running alongside the planting ridges.

While this means harvesters now lift far fewer stones with the potatoes, it creates two major problems for potato farmers and agriculture in general. The first is that the stones have to be ploughed up at the end of each season and re-scattered, before other crops can grow successfully. The second is that, over time, all this deep ploughing degrades the soil structure and reduces fertility, which means farmers then have to use more expensive fertilisers to maintain yields.

Deep ploughing, trench digging, and re-scattering is also labour and machine intensive, costing a lot in terms of time and fuel. The beauty of the Tillerstar’s innovative design is it lifts and sieves the soil, and forms the planting bed all in one go, without needing a separate trench for the stones. By reducing the number of ‘passes’ the tractors make, it saves money (one farmer in Ireland estimates he is saving £50 a hectare in fuel alone) and reduces soil compaction.


The Tillerstar gets its name from the four horizontal, rotating star rollers fitted behind the cultivator (see illustration above). The cultivator lifts the soil and throws it back onto the rotating stars. These then throw the heavy stones and clods forward into the bottom of the newly dug bed before letting the finer soil fall through behind to cover them.

The integral bed former, which the operator can change to suit soil conditions and produce the desired finish, then mounds up the earth ready for planting. As such, the Tillerstar only has to turn 6-7 inches of soil to create a bed that’s 12-14 inches deep – which further helps save fuel and reduce soil degradation. While scattering the heavy material in an even layer across the bottom of the bed not only improves drainage but also removes the need for re-scattering at the end of the season.

Winning awards and exporting globally

Despite only being launched three years ago, the Tillerstar has already won a string of awards. These include: The Innovation Award from the British Carrot Growers’ Association in 2012; a Gold Medal at the Royal Norfolk Show in 2013 for Best Commercial New Machine; an Award of Merit in the Best New Product or Innovation (Mechanical) category at LAMMA 2014. The machine is now being used successfully across virtually every main soil type in the UK and has satisfied customers in Ireland, Norway, Poland, Russia, and New Zealand (with new enquiries coming from Africa, the Middle East and America).

Meanwhile, a team from Cambridge University (led by Dr Mark Stalham) has been using Tillerstars in field trials aimed at helping potato farmers improve yields and reduce soil degradation. The long term results aren’t in yet but preliminary reports indicate “no reduction in yield”, even when planting “substantially shallower than a traditional 30-35cm.” As Lesley points out: “While the research is important, we already know we are doing something right because innovative and entrepreneurial farmers (including Guy Poskitt, who was Farmer of the Year in 2012) are willing to invest in our machines.”

    • Thank you Paul – really appreciate you taking the time to comment. It’s certainly a fascinating sector – and I’d love to write a whole article on it, if someone was prepared to commission it (Tekpro and Sands are just two of the other local companies I’d want to cover). If you would like to discuss this further, please let me know.

      Meanwhile, look out for this evening’s blog about one of Norfolk’s vineyards.

      Best regards
