Claydon Drill: 9.0m mounted Straw Harrow launched

Claydon's Straw Harrow is now available in a 9.0m version
Claydon’s Straw Harrow is now available in a 9.0m version.

Claydon has developed a new 9.0m mounted Straw Harrow to bridge the gap between the company’s popular 7.5m mounted and 12.5m trailed models. Made at the firm’s Suffolk, United Kingdom base, the harrow provides larger farms with greater flexibility and output, without incurring the higher cost of a trailed unit.

The Claydon Straw Harrow is simple, robust and effective. It achieves the high working speeds (15 to 25km/hr) that 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/ha.

The new model 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. As standard, it has five rows of heavy-duty, 14mm-diameter tines, but 16mm tines are available as an extra-cost option for exceptionally tough conditions.

Their wrap-around design enables high-speed turning on the headlands, avoiding 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.

Incorporating the same rugged design as other Claydon Straw Harrows, the 9.0m 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 width of the implement even when operating at speed.

High output and low fuel consumption are characteristics of all Claydon Straw Harrows. Typical/suggested figures for the 9.0m model, which has minimum power requirement of 180hp, include an output of 12ha/hr when operating at 20km/hr.

Claydon developed the Straw Harrow to improve crop establishment in all soil and weather conditions. Available in 3.0m, 7.5m and now 9.0m mounted versions, together with 12.5m and 15m trailed versions, this simple, cost-effective implement uses a tried-and-tested design and works without disturbing the soil’s biota or density, which is critical for improving its health.

The correct management of crop residue is particularly important when direct drilling. The Claydon Straw Harrow creates an even mulch that helps to preserve soil moisture and control persistent weeds. It also reduces slug populations by direct contact with the tines and breaks up their nests, disrupting their habitat and exposing their eggs to sunlight, causing them to desiccate.

Weighing 1,850kg and suitable for use on a Cat 3 linkage, the 9.0m Straw Harrow folds to 2.99m wide and 3.55m high for transport. Light boards and protection guards are standard.
