The flexibility of the Sicura seed drill
Sicura is a no-till seeder for small seeds, specifically designed by “ma/ag” of Casalbuttano (Cremona) for the operational needs of Italian and European soils. This piece of equipment can be used not only on hard soil but also on soils which have only been partially tilled is a trailed machine with a steering arm attachment and is equipped with a sturdy central frame for carrying hoppers (seed and fertilizer) and a trolley for the intermediate wheels equipped with large flotation tires. The main frames, placed in two rows (one in the front position, the other at the rear), act to support the sowing elements. The Sicura also comes in a pneumatic “SSP” version with a pneumatic transport system for seeds and fertilizer, a volumetric doser and hydraulic drive. The single seeding element is positioned on an articulated, shock-absorbing and adjustable parallelogram, characterized in turn by two soil scraping discs - one toothed and the other smooth - staggered and spread apart to accommodate the seed feed tube. The soil penetration of the furrower openers is ensured by a load of 200 kilos, which can be increased by means of springs with an adjustable preload. The end of the seeding unit can be configured with single or double toothed discs, or with mechanically adjustable pressure wheels, while the furrower can be equipped with a rubber wheel and beavertail seed presses.
The sowing depth is manually adjustable using a crank. In order to ensure constant inter-row spacing even when cornering, a need often encountered on hilly terrain or with non-uniform profiles, it is possible to customize the Sicura seed drill with a rear pivoting/steering kit. In fact, by acting on the second sowing line through an electro-hydraulically controlled rotation, the problem of overlapping or non-uniformity of the sowing lines is avoided and the desired inter-row spacing can be achieved. The Sicura seed drill is available in the trailed version with working widths of 3 meters (fixed or folding frame) and working widths of 4.5 and 6 meters.
The standard number of files for these is 17, 25 and 33 files, respectively. The weight varies from 3,150 kilos for the 3 meter versions to 8,750 kilos for the 6 meter version, while the power starts from a minimum of 100 and reaches a maximum of 250 horsepower. All versions can be equipped with electronic systems (ISOBUS protocol) for the operation and management of the sowing: electric drive with electronic control of the distributors and satellite connection to allow complete digital control of the seed drill and to take advantage of all the Precision Farming functions.
