The AST-MATIC is a robustly designed and constructed trailing Deep Ripper that has the ability to penetrate & breakup highly compacted soils. Featuring a rear crumble roller to ensure a smooth, level finish & optional spring loaded front coulters to enable it to handle high stubble loads & to aid penetration. The secret to the AST-MATIC is it shank design. Unlike some other styles of rippers that require very heavy frames to force the shanks into the ground, the AST-MATIC shank is designed in such a way that it pulls itself into the ground, meaning a simpler frame is needed and it requires less HP to pull. And this is without mentioning the AST-MATIC auto-reset trip function on the shank! Say goodbye to sheerpins, punches and your hammer! Auto Reset Trip on Shank The Patented Auto-Trip Reset function is a very basic concept. Simply put, when the shank hits an object in the ground that would normally break off a shear pin, this mechanism trips itself to allow the shank to ride up without damage. To reset, the operator just needs to stop, lift up the ripper and the shank will reset itself to its normal position. Plus this can be adjusted to make it as easy or hard as it needs to be for the conditions!
