Rata Subsoiler Mayfield (1)


Rata Subsoilers are the most user friendly & easy to use aerators available for sale in New Zealand. Subsoilers otherwise known as aerators are pulled through the paddocks to lift & fracture the soil composition in order to aerate the ground, allowing for deeper & more vigorous root growth.

This conventional subsoil aerator manufactured by Rata & sold through a network of NZ dealers features the same ‘V-frame’ design on machines with 5 legs.


The Rata ‘V-frame’ subsoiler advantage:

  1. Less drag between aerator legs: This makes Rata manufactured subsoilers the easiest aerators to pull, resulting in less fuel burn & less wear & tear to the tractor
  2. Does a cleaner job: When exiting the ground at headlands, the legs of a Rata aerator exit the ground independently & not at the same time, this eliminates ‘heaving’ which occurs with straight frame subsoilers.
  3. Lower power requirements: Because there is less drag between Rata aerator legs, they can be pulled with lower horse power tractors than their straight frame equivalents.

Conventional Rata Subsoilers are designed for tractors up to 120hp, the robust double bar ‘V frame’ & 16mm linkages ensure it endures tough ground conditions while standing the test of time. The easily adjustable 18” coulter skieths pre-cut the grass to leave clean cuts. The rear roller presses the grass back down & also doubles as the depth control in conjunction with the 3 point linkage of the tractor.

    Features & Benefits

    V formation of Rata Subsoiler frame and legs

    1 V Formation
    Rata Subsoiler legs are in a 'V' formation, this reduces drag between the legs making it easier to pull and uses less fuel. V formation also means the legs leave the ground independently at the headlands which eliminates 'heaving'

    Heavy Duty build of Rata Subsoiler frame

    2 Heavy Duty Build
    Rata Subsoilers feature a heavy duty build, the 12mm wear protected legs are securely bolted into mounts that are completely welded and gusseted onto the heavy RHS mainframe for strength.

    Shear bolt leg protection on Rata Subsoilers

    3 Shear Bolt Protection
    Rata Subsoiler legs are protected with 12mm shearbolts, this ensures the Subsoiler and tractor remain damage free when obstacles are encountered as the leg simply breaks away while remaining secured by the main mounting bolt.

    4 Roller Bearings
    The rear roller on the Rata Subsoiler is securely mounted into a sealed bearing to ensure smooth operation with minimal wear. The roller is also kept clean by a scraper mounted just behind.
