The MAESTRO CC is available as an 8-row version with individual seed boxes and a large 2,800 l fertilizer tank at 75 cm row spacing. The seed is provided at each row from the individual 70 l seed containers.
The larger MAESTRO SW version 12 resp. 24 row features a seed wagon with a capacity of 2,000 l for seed and 7,000 l for fertilizer also at a row spacing of 75 cm. The unique “SEED ON DEMAND” technology is a standard feature and is feeding all single metering units continuously from the large seed wagon.
Horsch ushers in the future of pneumatic single grain planting technology.with the Maestro range of maize planters. Due to its exact grain singulation the Maestro is ideally suited for maize, soya, sunflowers, and canola. The absolute precision while planting at a high speed of up to 15 km/h is only one of the outstanding features and has been proven already over the past years by farmers in Europe and the US.
The essential component is a very small compact metering unit (patented) with integrated electric motor. Unlike the competition with holes the singling is carried out by perforated discs with open slots to the outside. Thus, the grain passes over smoothly from a circular to a linear movement into the drop tube without any disturbing centrifugal forces. In combination with the new designed scrapers high distribution accuracy at working speed up to 15 Kilometers per hour is achieved at 90,000 grains of maize per hectare.
A sensor integrated in the drop tube registers not only the exactly number of grains, but also their distance. The driving speed can be adapted to individual requirements and the placement accuracy.
Each planter unit has a sensor system and a job computer of its own. The data are gathered in the operation terminal. At any time, the driver can clearly see the exact missing and double spots as well as the variation coefficient for every single row. Thus, the driver can respond any time to the most different conditions by adjusting the working speed.
Unique metering unit
The metering disc is the key element of the new development. No holes than usually, but grooves that open up to the outside. The crucial factor is the smooth transition of the grains from a circular to a linear movement in the placement area.
During the singling process the grain is sucked in smoothly in the slot and is continuously moved to the outside by means of the scraper and thus put in linearly into the drop tube without being influenced by centrifugal forces. >
Innovative scraper design
Metering unit cover with scraper (left) to avoid double spots; second scraper (right) for leading the grains from a circular to a linear movement reducing inadverted rolling or rocking motion considerably.
Compact metering unit
The newly designed single grain unit is consisting of the metering unit and an integrated electric drive. All seal system required in the vacuum area is a gap ring totally maintenance- free and does not create torque. The electric drive unit combines motor, gear drive, bearing and job computer per row in a capsulated casing with a minimum of moving parts.
Control of placement quality
Another important innovation is the grain sensor that is integrated in the drop tube which cannot only register exactly the number of grains, but also their spacing. The missing and double seeds as well as the variation coefficient for each row is displayed in the operation terminal. The driver can react to differences in seed quality and soil conditions and use the planter to its full capacity. He can influence the placement quality immediately by adjusting the working speed or changing the adjustments at the metering unit.
The sensor in the drop tube registers not only the number of grains, but also the distance.
For many years already, HORSCH has been concentrating on cultivating and planting for row cropping as part of the HORSCH conservation tillage program for precision farming. The concept of the FOCUS Strip Till planter is to remove the residue from the row area, to loosen the soil in strips, place fertilizer in the tilled zone and to plant, all in one single pass.
The great feature of the Focus TD Planter is that it can be used either as a wheat planter (or any other cereals) or to plant maize (or soy, sunflower, sugar beet and canola).
There are two different toolbars available to be mounted at the rear of the cultivator section. The coulter rail for wheat sowing can be set e.g. to plant twin rows with 18 cm spacing and apprx. 20 cm spacing between the twin rows over a total working width of apprx. 5.60 m. The tine configuration of the Strip Till cultivator unit is set to work with 15 tines. There are always two TurboDisc seed coulters for one TerraGrip tine respectively one tyre packer wheel.
The fertilizer deposit is centrally distributed from the large 5.000 Liter hopper which is divided in a 30:70 partition for seed (grain) and fertilizer.
The TerraGrip tines are fixed between two plant rows and place the fertilizer (if wanted) in two positions at different depths. The TerraGrip tines can work up to a depth of 35 cm.
When the Focus TD planter is converted to work as a maize planter the starting point is a configuration of 8 Strip Till tines in front and 8 maize planter units spaced 75 cm apart. The seed is provided at each row from the individual 70 l seed containers whereas the fertilizer is conveyed from the large hopper to the TerraGrip tines.
Like for the range of MAESTRO maize planters the latest technology of the patented HORSCH single grain technology is used for the Focus TD maize planters with the exception of the “Seed on Demand” technology
