5.0 SBR HITCH
5.1 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 the 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
5.2 Benefits:
 the stubble protects the young seedling 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
affect the operation of the S.B.R.
