In order to increase the unit width, but also 3 to 5 planters in parallel, so that the total width of the grain sowing unit to 12 to 15 meters, or even wider.
The operating speed of the sowing machine is generally 8 to 10 km / h, some models up to 11 to 12 km / h; single plane width is generally 6 to 9 meters (8 to 12 lines), some models up to 12
Grain machine speed is generally 10 to 12 km / h, and some models up to 15 to 16 km / h; single plane width is generally 6 to 7 meters.
But the actual working width depends on the tractor at a higher operating speed can play the traction power, hanging sowing machine is also limited by the capacity of the tractor suspension.
