- Metal-Fach’s product range includes five disc cultivator models: U740, U740/1, U741, U710, and U710/1. The machines are designed for coupling with seeders. The available working width range is from 3 to 6 metres. All cultivators come with 24 discs. The working parts are installed in two rows on the machine. The disc diameter varies from 510 mm to 560 mm, depending on the model. The cultivators ...are based on solid and stable frameworks that ensure safe and efficient operation. The U740 is distinguished by its wide range of working depth that can be easily adjusted from 5 cm to an imposing 18 cm. The remaining two models may cultivate down to a depth of 15 cm. The U740 may feature a hydraulic control system, which is available as an optional accessory. This model’s discs are protected by rubber shock absorbers. The individual versions vary in the working depth adjustment method, i.e. based on a packer roller (on the U740/1) or hydraulic power gear (U740). The U710/1 cultivator has two rows of Ø 560 mm toothed discs which ensure full undercutting of soil and mixing of plant remains and hay. The machine has a stable frame and compact overall dimensions. The working width is 4.5 m. The U710 is the largest cultivator in the series with an impressive working range of 6 m. Its robust and stable frame folds using hydraulic actuators, and the compact structure is small enough for hauling on public roads.
