Strip tillage seed drill manufacturer, Claydon Yield-o-Meter Limited alleged that Mzuri’s popular Pro-Til and Pro-Til Select single pass drills infringed their UK patent no. 2,400,296 and their European patent no. 2,051,576.
Maintaining that there was no infringement of the claimant’s patents, Mzuri’s defence at trial also included arguments that the patents were invalid due to lack of inventiveness over existing prior art and prior use of the invention contained in the UK patent in public.
The patents related to the configuration of inline tines for cultivating and seeding in one pass, which is a concept that Mzuri believes dates to the earliest seed drills in history.
Speaking for Mzuri, Martin Lole describes the 3-year long court case as entirely avoidable and detrimental to agricultural innovation in the UK.
“We have been disappointed to have been the target of a court case brought about by another British manufacturer, which sought to claim damages and prevent us from selling our flagship product into the market.” Says Mr Lole.
“Single pass technology such as one tine in front of another has been around for many years, even documented by early innovators such as Jethro Tull and has been popular (particularly in the US) for some time prior to the patent priority date. We have always maintained that we do not infringe the Claydon patents, and it is very sad that this whole thing which has been entirely unnecessary could have been easily avoided.”
“Despite our best efforts to discuss the disagreement openly and honestly, Claydon were determined to draw it out into a lengthy and costly legal battle which served no one.”
“I would like to sympathise with those customers who were inaccurately warned off buying a Mzuri Pro-Til for risk of infringing patents which were, as we now know, invalid.”
After the three-day hearing, the Judge handed down the decision on 22nd April 2021 that the patents are to be revoked due to a combination of a lack of inventiveness over existing prior art and prior use of the invention in public.
Kicking off our 10th Anniversary Year we celebrate Mzuri’s history in the January issue of Direct Driller magazine. Martin Lole talks about how he first came to develop the Mzuri single pass system on his farm in Worcestershire and how the company has grown ever since.
Now available across four continents the Mzuri Pro-Til has proven to be a reliable solution to a range of climates and challenges across the world.

New Autumn Finance Offer launched
At Mzuri we have recently launched our new finance offer for all Pro-Til drills ordered this Autumn.
Based on a 50% deposit and five annual payments, growers could own an innovative single pass Pro-Til Select 3T for as little as £2.50/ha per month when farming hectarages in line with the Mzuri user average of 275ha. The figure is intended as a guide only, but growers who farm a larger area can expect an even lower cost per hectare to switch to the system.
As part of adopting a single pass establishment system, there are significant cost savings to be made over conventional crop establishment, by consolidating multiple operations into one. The Pro-Til prepares a targeted seedbed and reconsolidates the seed whilst applying fertiliser, slug bait and other crop protection products in one go. It is also this targeted approach to cultivation that gives the Pro-Til its recognised soil health credentials that goes on to improve soil structure within a field and supports higher yielding, healthier crops.
For those looking to take advantage of the Mzuri finance scheme this Autumn, the promotion is valid until 31st January 2021 and is applicable across all Pro-Til models, subject to terms and conditions. For more information call the Mzuri office on 01905 841123.
Featured in October 2020’s edition of Farmers Guide, knowledge exchange officer and trial farm manager, Ben Knight talks about how drilling direct into stubble gives growers the flexibility and security they need in difficult seasons.
With the memory of the relentless wet weather last Autumn, Ben looks at how growers can give themselves the advantage whether their hand is forced by weather or changing government policy.

Featured in July 2020’s edition of Direct Driller, we go back to basics with the Mzuri system and look at the Pro-Til’s clever design.
Highlighted by the dry spring, the Pro-Til’s ability to generate a perfect seedbed without loosing critical moisture has been a key factor in the success of spring cropping on the Mzuri trial farm. Farm Manager Ben Knight explains:

Fourth generation farmer, Chris Heath and his family have been farming Warwickshire countryside along the historic Fosse Way since the 1940’s and now farm 3300 acres. With a broad portfolio of soil types ranging from sand to heavy clay, the family’s enterprise is diverse and in addition to their arable enterprise, they also run an agricultural manufacturing business – Heath Engineering. Manufacturing a range of tele-handler implements including the Heath Super Chaser, the company also makes 16t grain and silage trailers and 32’ flatbed trailers. Alongside this Chris and his family also operate the diversification, Newbridge Straw Products and produce straw bedding products for the Equine and Poultry markets, largely using raw materials produced on their own farm.
Up until more recently, the arable enterprise has largely been plough based but in response to the rising cost of fuel and increasing grain price volatility, Chris and his family have started to move away from heavy cultivations. The farm went down the min-till route with a popular tine drill which proved beneficial but after poorly performing headlands – and a lot of them, the decision was taken to purchase a Mzuri Pro-Til 4T to increase crop consistency whilst still keeping fuel usage down and minimising machinery and labour costs.
Described as a ‘leap of faith’ Chris took delivery of the four metre Pro-Til at the start of the year and after less than 6 months of ownership, has defined the Mzuri as a ‘god send’.
Chris suggests that one of the most noticeable differences in his Spring crops this year is the consistency across all his different blocks of fields, as well as a staggering improvement of consistency within each field.
This consistency is most remarkable on a headland of Spring Barley that was earmarked for woodland due to its consistent poor performance. “The headland in front of the wood has always performed poorly and lies very wet. With the Mzuri, it’s allowed me to drill when its ready and the front leg lifts out wheelings giving me good establishment edge to edge – it’s all good.”
Part of the reason Chris believes the Mzuri Pro-Til performs so well on headlands is down to the patented independent pivoting coulters. Accommodating both horizontal and vertical movement, the coulters pivot to follow the front legs even around tight corners and places the seed in the centre of the tilled strip, the perfect position for quick, even germination.
It’s this ability to bring all areas of the field up to a good standard that Chris believes will give him the edge on yield. With a lot of smaller fields, headlands can make up a large proportion of the cropping area and having these perform as well as the middle of the field should see a big impact on the farms average yield.
Chris puts this consistency down to the Pro-Til’s leading leg which loosens his heavy clay soils and prepares a nursery seedbed to drill into, whilst leaving structured soil between the rows. The drills central row of weight bearing wheels spread the weight of the machine evenly over the tills and allow for even reconsolidation of the seedbed. This has been particularly beneficial for fields that were to be conventionally drilled in the Autumn and cultivated with a Vaderstaad Top Down in preparation but went on to slump over the winter due to high rainfall. In this situation, Chris says “The Pro-Til’s leading leg cultivates just enough to allow the crop to root well early on and gave it the best start.”
The drills leading leg has also allowed Chris to place his seedbed fertiliser below the seed which he suggests is another reason why his crops have performed so well this Spring. Post drilling applications of fertiliser could still be seen on the surface at the end of May, and with no rain forecast, Chris believes there could be a real benefit to placing all of the fertiliser requirement below the seed at drilling. He will be trialling this next season and hopes this will not only give the crop all the nutrition it needs where it needs it, but also minimise his risk against dry weather, and reduce the need for additional passes saving time and money.
Favouring the targeted applications of strip tillage, Chris also places his seedbed slug pellets down with the seed. “There’s no need to waste it between the rows, instead we’ve applied it exactly where it’s needed” Using a relatively low dose, this targeted application should see the active be just as effective as broadcast, if not more so and more responsibly used.
With a lot of his Autumn drilling not gone as planned, the Mzuri has shown its versatility to establish crops into a wide range of cultivated and non-cultivated fields. Moving forward, the farm will be planting direct into stubbles which will retain moisture and help improve the health and structure of his soils.
Being a new user, Chris has been very impressed with Mzuri’s level of service and support that is available to operators and has had no down time this Spring. He has even seen an increase in interest for his contracting services since adopting the new system and after picking up further income drilling Maize, it seems there could be further demand for strip tillage establishment in the area which the family are well placed to accommodate.
Plus, with a desire to keep costs down, Chris has been impressed with how well the wearing metal has performed so far. “Our front wings still have plenty of life left in them after over 1800 acres this Spring. We also find having the versatility of the different wing and coulter combinations very useful when growing a wide variety of crops like we do.”
As a leap of faith that has paid dividends so far, Chris’s takeaway message for anyone considering the strip tillage system is that it can often be a change of mindset but you will get out of the system exactly what you put in. He suggests by working with the system and understanding what you’re trying to achieve – the results speak for themselves.
