Combination drill buyer’s guide

Min-till, strip-till and no-till may be all the rage but the once ubiquitous combination of power harrow and piggy-back seeder still retains a place on many farms.

In fact, manufacturers report a recent surge in sales of such implements, particularly of the less sophisticated mechanical or gravity type drills reviewed here, which have a full-width seed box.

Improvements in metering wheel design have improved seed selection and delivery accuracy – although a pneumatic system is still regarded as the best solution for achieving accurate in-row seed spacing at high working speeds.

These implements are mainly used ‘on the plough’ so remain especially popular on mixed enterprise farms and in northern England and Scotland, where mintill and other non-inversion techniques are more difficult to manage thanks to a tighter window between harvesting one crop and sowing the next.

Further south, the power harrow-seed drill can also perform a valuable role in partnership with a mouldboard plough when dire autumn weather sends mintill plans out of the window.

Many a grower facing that situation has been thankful for a combination’s ability to work in less than ideal conditions and get crops in.

Not that the power harrow-seed drill combination is confined to ploughed land – certainly not to the extent it once was. Thanks to the development of single- and double-disc coulters with increased working pressure from typically 35kg to 50kg, there are machines that can readily handle trash-laden seedbeds.

This type of drill can therefore be part of a reduced tillage approach that eliminates expensive ploughing and instead uses speedy tine or disc cultivation to produce a stale seedbed. A single pass with the combination then completes seedbed preparation and sows the crop.

It may not be the speediest way to get grain and oilseed crops established but it offers a viable option when a combination seeder is considered the best option for other cropping situations, such as wheat following sugar beet or potatoes.

While most of drills are mounted on power harrows, they are certainly not confined to this implement.

Amazone, Kongskilde, Kverneland and Kuhn are among suppliers with fitting kits for rotary tillers but it is a less common application. A more popular approach is to install a box drill on a tine cultivator designed for this purpose and so create a faster-working, cheaper to run combination for use on lighter soils.

On power harrows it used to be the case that integral drills were carried on the host implement’s headstock and gear trough; today, the disadvantages of that approach are avoided by carrying the drill on the packer.

This does mean that a pretty substantial packer is needed – usually 500mm diameter minimum, with 600mm generally recommended – but at least the weight is carried where it can do most good – and also least harm.

There is less stress and strain imposed on the harrow structure and it is free to move independently when necessary – upon hitting a boulder or other buried obstruction, for example.

Manufacturers mostly produce fitting kits to suit their own power harrows, as well as tillers and tine cultivators if they make them.

Sulky distributor Reco has fitting kits for the Breviglieri harrows is supplies in addition to those for Sulky implements, while Kongskilde has an extensive list of mountings to install its MasterLine seeder on Howard, Kuhn, Lemken, Kverneland and Lely/Tulip harrows, as well as the leading Italian makes and a number of other implements.
