  • Milestone Hydraulic Quick Adjust Sizer and Milestone Sizing Star

    Milestone Hydraulic Quick Adjust Sizer and Milestone Sizing Star

    The secret to cutting seed is in the sizing. Milestone's quick adjust sizer and sizing star are designed to provide unrivaled sizing accuracy and ease of use. Proper sizing helps ensure a uniform and consistent size seed piece.

    Sizer motion is not affected by debris or contamination.

  • Progressive Rollers

    Progressive Rollers

    Each progressive roller is a continuous pour of urethane with no seam between donuts, eliminating a site for pathogens to settle.

    The unique design of Milestone’s progressive roller provides a stable cutting surface and optimal potato alignment to the blades, all without reducing capacity.

  • Stainless Steel Blades

    Stainless Steel Blades

    Stainless steel blades offer several advantages:

    1. Cleaner cut allowing the seed piece to heal faster so energy is dedicated to growth in the field.
    2. Smoother surface provides a more consistent transition to the horizontal blade.
    3. Increased contamination resistance reduces places for pathogens to take hold.
  • Easy and Accurate Adjustment

    Easy and Accurate Adjustment

    The sizers, coulter blades, and belt speeds can all be effortlessly and accurately adjusted while the cutter is operating. The easier it is to adjust the cutter the more often it will be adjusted, resulting in better quality seed pieces.

  • Ultra-Soft Sponge Drums

    Ultra-Soft Sponge Drums

    Ultra-soft sponge drums are extremely gentle on the seed piece and properly conform around the seed piece for accurate presentation to the horizontal blade. Milestone’s sponge drums are designed and tested for increased durability.

  • Quick Adjust Trim Rollers

    Quick Adjust Trim Rollers

    Standard on 60”, 72”, and 84” models, the quick adjust trim feature provides precise control of trim elimination.

  • Premium Grade Belt

    Premium Grade Belt

    All Milestone Cutters and other machines use premium grade Legg or comparable brand belting. Our premium grade belting significantly improves tracking and is more impervious to rips, tears, and other damage.

  • Belt Lifter

    Belt Breaker

    Easily pry frozen belts free from rails so you can get back to cutting faster.

  • Double Deck Cutting System

    Double Deck Cutting System

    Milestone’s innovative two deck cutting system increases capacity and produces a more consistent sized seed profile.

  • Bruise Protection

    Bruise Protection

    Full width elevator flights, padded/baffled chutes and ultra-soft sponge drums are all gentle on the seed pieces. Even though the potato is being cut it is still important to prevent bruising and damage so the seed dedicates more energy to growth and less energy trying to heal itself.
