The HORSCH Maestro
Fast – precise – versatile
The new HORSCH Maestro was presented on the occasion of the Agritechnica 2011 and has been awarded with the prize Machine of the Year 2012. It excels due to its speed, presicion and versatility. The Maestro allows for sowing speeds up to 15 km/h while at the same time achieving extremely precise singling results. Thus, the farmer can make optimum use of sowing windows.
Two series for a wide variety of requirements
The new Maestro is available as the CC series with 8 and 12 seed rows and row spacings of 45, 50, 70, 75 and 80 cm and as the SW series with 12 and 24 seed rows and row spacings of 70 and 75 cm.
The Maestro CC excels due to its compact design and the low dead weight. The fertilizer hopper has a capacity of 2,800 litres and the seed is supplied by seed containers at each row.
The Maestro SW is equipped with a central hopper for 2,000 litre seed and 7,000 litre fertilizer. The seed units are supplied by a Seed on Demand system.
The Maestro disposes of a completely new seed organ. The seed coulter is a double disc coulter with two depth control rolls. The seed that is led into the soil via a fall sluice is optionally pressed into the seed furrow by a press wheel. Two V-shaped press wheels whose pressure can be adjusted in steps are responsible for covering and pressing.
Unique metering system
The metering disc with grooves that are open to the outside are the core element. In combination with the newly designed scrapers very good singling results are achieved even at high speeds. The smooth transition from a circular to a linear movement is crucial. The grains are placed into the fall sluice without any interfering centrifugal forces, thus avoiding rocking motions. The grains fall tangentially into the soil and the rolling away of the grains is reduced considerably.
Extremely compact grain unit
The unit consisting of metering unit and integrated electric motor is extremely compact. Thus, the unit can do without an abradable seal. The inserted gap ring is non-wearing and does not create any torque. Thus, the power requirement is reduced to approx. one ampere. The electric drive combines motor, bearing, gear box and job computer and has been designed for a minimum of moveable parts. The metering unit can be used for maize, sugarbeet, sunflowers, soybeans, sorghum and rapeseed.
Constant control
The grain sensor that is integrated in the fall sluice does not only record the number of grains, but also their spacing. The driver can retrieve missing and double spots as well as the variation coefficient for each row at the operation terminal. Thus, the driver is able to react in time to various situations and to work in an optimum way. By means of the registered data the farmer afterwards gets exact information about his sown areas.
