The first Tillage 2009 event takes place at Cirencester on 15 September, Peter Hill took the chance to look at low-cost, low-complexity drills
For some growers, tine coulters are an essential element of a seed drill, usually to cope with a large quantity of stones in their soils.
But with a relatively simple structure, few moving parts and soil-engaging components that do not cost a fortune to replace, they also have relatively modest purchase and running costs in their favour.

True, it is possible to rack up a sizeable price ticket by going for the largest sizes and ticking all the option boxes. But for operators who are happy with a modestly-equipped machine that will get crops established without a lot of fuss, there are tine drills to be had at modest prices.
That also makes such machines a candidate for another role – as back-up to a bigger, more specialist seeder. Especially for odd corners and small fields but also for times when bad weather throws up conditions that make it difficult for minimum tillage units to work effectively.
Taking an arbitrary £40,000 price ceiling as the cut-off point provides a big choice of seeders from basic models costing less than half that amount to ones with the sort of equipment fitted as standard that are listed as options on others.

The Aguirre range kicks off with a 3m plain drill, while the Soladrill line-up goes from 4m with plain drills and versions that include a tine cultivation unit incorporated into the build. There is also a piggy-back version for use on a power harrow or a tine cultivator.
Coulter control comes in for close attention on these seeders, with French manufacturer Techmagri adopting a similar principle to that on the Soladrill of using a coil spring at a shallow angle. The idea is that any movement at the coulter tip requires only a small deflection of the spring and therefore more consistency in spring rate.
The latter comes complete with a paddle tine levelling unit across the front and a flexible steel roller across the back, plus other features that are optional on drills with a lesser starting spec.
Kverneland’s freshly revamped Accord Tine-Seeder is another drill that can have paddle tines across the front to crush and level clods ahead of the coulters. These are also of the spring tine type, but deflecting against a leaf rather than coil spring and arranged in five rows for maximum trash clearance rather than the three- and four-row choice offered previously.
Band sowing is the technique favoured for the Dale All-Till and Simba-Horsch Sprinter ST – the latter being the only trailed unit in this selection. The SimTech T-Sem, meanwhile, takes Aitchison coulter technology, producing an inverted “T” slot primarily for direct reseeding of grass, and applies it to the cereal sowing scenario.
