Seed Hawk TOOLBAR 2008 - Manual (Page 53)

SPECIFICATIONS and OPERATION OF SBR HITCH
Requirements:
- must be seeded with G.P.S. auto steer and same row spacing the year before
- must seed in exactly the same direction as the previous year
- guides the Seed Hawk openers between the stubble rows from the previous year
- sensing arm follows between two rows of stubble 4” - 6” above the ground
- as the openers get closer to one row than the other, the stubble hits the paddle of the sensing arm,
activating a switch, sending power to the directional control valve
- the directional control valve operates the hydraulic cylinders moving the seeder to the side while the
tractor remains in a straight line
Benefits:
- the stubble protects the young seedlings from the wind
- better seed placement by not seeding through the stubble
- better soil to seed contact when standing stubble is left standing
- less soil is thrown to the side by the openers because the stubble tends to corral the soil being
thrown. This may allow for slightly higher seeding speeds and less soil disturbance
- concave shaped paddle is less likely to ride on top of straw row than a flat paddle, or ground sensing
device
- paddle senses standing stubble not the ground, therefore harrowing will not effect the operation of the
S.B.R.
