      • Model 112 with shear-bolt protected shank with 7,500 lbs. of shear pressure for use in rock-free soils

    • 3/4" thick high-stress,forged-alloy shanks provide maximum strength and minimal disturbance
    • Heat-treated, austempered 1-3/4" wide replaceable points dig through the hardpan
    • Points feature raised-center, tapered design for less soil disturbance at higher speeds
    • Hourglass-shaped, heat-treated cast invertible wearbars add to shank durability and subsurface soil fracturing
    • Heavy-duty, double-frame all-welded construction with 6"x6" rearbar and 38" underframe clearance provides ideal residue flow
  • Standard tool-free adjustable stabilizer wheels with stubble-resistant tires assure a consistent working depth
  • Front-mounted swivel coulters with 1,500 lbs. of downpressure easily cut through the heaviest residue and features heavy-duty 6-bolt hubs with recessed endcaps and ride on a lip for increased durability
