Maestro has gentle touch with delicate seeds

DUGALD, Man. — Like a symphony conductor keeping precise meter for the orchestra with his wand, the Horsch Maestro seed metering system precisely conducts the flow of soybean, canola, sunflower and corn seeds.

Before launching into the Maestro design process, Horsch engineers studied the many conventional planters already on the market. They saw that most metering units were harsh on seeds. Their air delivery systems contained lots of dead heads, turns and plumbing. Seeds were being fractured before they even got into the soil, says Horsch field representative Jeremy Hughes.

“The Maestro SW planter has fewer transition spots so it’s gentler with seeds,” says Hughes. “A Venturi system sucks seeds out of the tank and fills the seed cup. On each row unit, a vacuum behind the disc pulls the seed into position. As the disc rotates, it drops the seed into the seed trench.

“The stainless steel metering discs have proven to be more accurate and they last longer than other types of metering discs. The disc releases the seed downward for precise seed placement in the furrow.

“Producers can switch discs for planting other crops quickly without requiring huge conversions. The canola kit includes stainless steel discs plus metering components for small seed crops. The kit is designed to allow quick change between regular row crops and canola on any Maestro SW planter.”

Hughes says the Maestro achieves accurate singulation because of the electric-driven meters. They also allow individual row shutoff and curve compensation to eliminate double-planting and ensure consistent planting rates throughout the entire field. He adds that the system requires low amperage, so it’s able to run off the tractor, unlike other systems that require generators to provide electricity.
