Butterfly mower on a green tractor in a meadow

Front-mounted double-knife mower Seco Duplex

Our front butterfly mower impresses with its  excellent overview when mowing and maximum efficiency. As the entire machine is in the driver's direct field of vision, obstacles can be detected early and without difficulty.

The entire working width can be fully utilised without creating unnecessary overlap. At the same time, the individual cutter bars adapt independently to the ground, thereby ensuring the best cutting results and a clean cut even in difficult conditions. 

This mower is available in working widths from 6.5 m to 10 m.
