Available on machines from six to 12 rows, and with row spacings from 37.5cm to 80cm, seed rates can be varied manually from the tractor cab or as determined by a variable rate map.
Kuhn reckons that varying the seed rate in response to soil conditions can result in seed savings of 2-3% when used in conjunction with automated row shut-off, and optimising plant populations can result in an potential yield gain of 5-8%.
Other Maxima 3 news (both mechanical and electric versions) includes an improved seed selection and ejection system, which says the company, enables accurate seed placement at working speeds of up to 10km/hr. The new seeding unit parallelogram is claimed to increase accuracy, and the new coulter pressure system produces up to 180kg of downward pressure.
Suitable for drilling maize, sunflower, beetroot, sugar beet, peas, beans, onions and other crops, the Maxima 3 range includes 12 models, with electric drive versions being available in mounted formats including telescopic, foldable and telescopic with adjustable spacing.
