NH3 Row Unit Design

  • The .75” NH3 knives feature a steel .375” tube for efficiently applying anhydrous ammonia underneath the soil
  • The CoverMax closing coulter sealer features two notched blades that are angled to fill and seal the slot which prevents fertilizer loss
    • Greaseless 1.25” plated pivot shaft with self-lubricating bushings and flat-face, zero-maintenance hubs with a 4-bolt design provide long-term, trouble-free use
    • Disc sealer arms operate independently from each other allowing for superior trash flow and continuous soil contact
    • 17” of overall travel and 9” of vertical travel from working depth allows the sealers to climb over obstacles
    • Adjustable blade position and pitch allow you to customize to match your soil profile



Anhydrous Ammonia Control

  • Tool-free adjustable rear nurse tank hitch features a retractable design for easy hookup
    • This hitch design retracts towards the front of the applicator so it can automatically lock when the operator drives forward, increasing the safety of the machine because the operator does not need to remember to back up to lock the hitch

  • The anhydrous ammonia nurse tank coupler utilizes 1.25” plumbing as standard with 1.5” available as optional
