Chopper Spreads Straw With Pressurized Air
According to Redekop, the spreading width can be changed by lowering or raising the tailboard of the chopper from 5¦ above horizontal to 35¦ below horizontal. This results in a spread range from 45 ft. to 20 ft.
Testing done by PAMI showed the MAV (Maximum Air Velocity) chopper is capable of discharging straw evenly at up to 50-ft. widths if there's no wind.
The chopper is equipped with stationary knife bar blades spaced 1 in. apart, and beveled blades on the rotor that together produce an extra-fine cut. The blades are reversible with the option of upgrading to a carbide coated self-sharpening blade for longer wear life.
The knife bar bank is designed so it will rotate out of the way if a large foreign object is put through the combine, thus minimizing damage to the stationary blades, the rotor blades and the straw chopper itself.
Various options to improve a combine's straw chopping ability are available for each make of combine. Redekop Manufacturing Co., sells full-body MAV choppers, as well as rotor replacement kits. Pricing ranges from approximately $2,500 to $8,300 (Can.).
