Subsoil Blade Attachment for Single Spade Plow

This will attach to the shaft of the single spade plow to cut narrow ruts into the subsoil to facilitate water absorption on the keyline. This will shatter compacted soil without excessive disturbance of the ecosystem. Crossbar is fitted for up to 20 different blade placements for customizable spacing. If you are going 18" or deeper, you need 6"x1" according to Sweiger. If you are going 6", 1x3 will do. We are going 6" down, so we are using 1x3. Our crossbar is a 4x2x1/4" tube. Width is 58" so that it runs on a track just narrower than Lifetrac's wheels. More on Keyline Subsoil Plowing

Bunyip Slipper Imp by Ken Yeomans

• Give more available water in profile in times of severe heat stress and help lengthen the watering time pattern.
• Help prevent scald because less water lays on top.
• slows down water rate and increases penetration on sloping banks.
• Gives a 4-6" profile for super phosphate to work on thus increasing its returns to the grasses.
• Allows more water to be under the root system thus drawing the roots down.
• Tests show new roots deeper in the subsoil.
• Deeper and longer roots means you have healthier grasses

• Rigid tynes
• Spring release tynes
