Claydon, the European market leader in direct strip seeding technology with its Claydon Opti-Till® System, will exhibit 4.8m and 3m Seed and Fertiliser models from its new range of Evolution mounted drills, together with a new 9m Straw Harrow and 4m TerraBlade inter-row hoe on its stand (Hall 6, Stand 6.600) at LAMMA 2022 (NEC Birmingham, 4 & 5 May 2022).

“This year’s event represents a milestone, both for Claydon and LAMMA, marking not only the invention of our direct strip till drill in 2002 but also the 40th anniversary of the UK’s leading farm machinery show. We are delighted to be exhibiting and congratulate the LAMMA organisers on this magnificent achievement,” Jeff Claydon, CEO of Claydon Yield-o-Meter Limited states.


A 4.8m version of Claydon’s new Evolution mounted drill.

Building on Claydon’s extensive experience of direct strip seeding technology, the nine new Claydon Evolution mounted drill models take direct strip seeding to the next level. Combining enhanced operational functionality with the tried and tested features which have made Claydon Opti-Till® the crop establishment system of choice for growers who want to reduce costs, increase productivity, and improve soil health, they will be available for delivery from autumn 2022. Prices will be between Claydon’s current Hybrid mounted drills, which they supersede, and the company’s Hybrid Trailed models.

The tried and tested two-tine technology which Suffolk arable farmer Jeff Claydon developed in 2002 is at the heart of every Claydon drill, a major benefit being its ability to cope with extremes of weather which are becoming increasingly frequent. It delivers exceptional versatility in all climatic conditions, soil types and crops, yet moves soil only in the growing zone. The front tine removes compaction, aerates the soil, and creates drainage in the rooting zone, whilst the seeding tine deposits seeds in the surface tilth. Zonal cultivation means that the previous rooting and soil structure is not destroyed, allowing worms to thrive and soil biota levels to improve.
With working widths of 3m, 4m, 4.5m, 4.8m, 5m and 6m, the Evolution models incorporate 9, 13, 15 or 19 tines and most feature a 1910-litre hopper, 160-litres more than the previous Claydon Hybrid mounted models. The 3m Evolution 3MF and 4m 4MRF have a 2700-litre tank, an increase of 600 litres, which is split 50:50 between seed and fertiliser. The larger hoppers reduce downtime and increases output, while second and third hopper options for applying multiple types, varieties and sizes of seed are available to further enhance versatility.

All models feature as standard a hydraulic fan, Artemis metering control, tramlining facility, front tine/7″ A-share configuration, double rear toolbar and road lights. Typical daily outputs range from 20ha for the 3m Evolution which requires at least 150hp to 40ha for the 6m version which needs a minimum of 300hp.

The Evolution line-up, which includes a 5m unit and 4m rigid grain/fertiliser model, incorporates new features to improve operational functionality. Seed depth adjustment is now controlled hydraulically, improved access to the metering unit allows easier calibration, while front-mounted discs which are operated hydraulically from the tractor seat can be specified for seeding into high residue situations.
Other features include quick-fit knock-on/knock-off coulter options for the standard leading tine and A-Share to low disturbance twin disc and tine options. Multiple seed tool options allow a wide range of crops to be drilled across different soil types and situations, while the quick-change facility allows fast, easy modification when required. A large, easily accessible toolbox incorporated into the step frame is also standard.
Options include GPS variable seed rate capability, pre-emergence marker arms, front disc toolbar stone protection, micro fertiliser applicator, low-disturbance twin tine kit, slug pelleter, blockage sensors and a light and vision kit.

The strength and rugged design of the Claydon Evolution keeps running costs to a minimum with reliable operation and minimum downtime, enabling fuel-efficient farming and minimal soil disturbance in all sowing scenarios, without compromising crop establishment or yields. The drill operates accurately, reliably, and inexpensively across a wide range of situations, the simple, robust design and great flexibility allowing it to be used in the autumn or spring to establish any crop that can be air sown.


The Claydon Straw Harrow is simple, robust, and effective. It achieves the high working speeds (15 to 25km/h) which are necessary to create a micro-tilth in the top 30mm of soil, as well as breaking up straw so that it decomposes rapidly. It does so quickly and cost-effectively, typically using just one litre of fuel per hectare.

The new 9m mounted version bridges the gap between the popular 7.5m mounted and 12.5m trailed models, providing larger farms with greater flexibility and output without incurring the higher cost of a trailed unit. It incorporates 75 double tines, each of which is attached to the frame by a unique fixing that enables the tine to pivot and absorb shock loads when working in stony conditions or turning.

The ‘wrap around’ design of the tines enables high-speed turning on the headlands, which avoids leaving heaps of straw behind that interfere with subsequent operations or crop development. Tine angle is hydraulically adjustable from the tractor cab for optimum tilth and straw flow, while huge inter-tine and under-frame clearances ensure that the implement will work without blocking. Five rows of heavy-duty 14mm-diameter tines are standard, but 16mm tines are a cost option for exceptionally tough conditions.

Incorporating the same rugged design as other Claydon Straw Harrows, the 9m mounted version features a box section frame manufactured from high grade steel, while the wing pivot pins are greaseable and bushed to ensure a long service life. Twin hydraulic rams on each wing section enable them to fold vertically and remain level in work, creating a uniform tilth across the full width of the implement even when operating at speed.

The typical/suggested output figure for the 9m model, which has minimum power requirement of 180hp, is 12ha/h when operating at 20km/h. Weighing 1850kg and suitable for use on a Cat3 linkage, it folds to 2.99m wide and 3.55m high for transport. Light boards and protection guards are standard.

Claydon Straw Harrow are now available in 3m, 7.5m and 9m mounted versions, together with 12.5m and 15m trailed models. The company’s product range also includes the 6m TerraStar® light rotary cultivator for situations where more soil movement is required than can be achieved with a Straw harrow, together with TerraBlade inter-row hoes from 3m to 8m wide which provide a low-cost, mechanical method of controlling weeds in band-sown combinable crops.
