Offset Discs

One Heavy Pass Instead of Three Light Ones
Built on 85 years of Willett design, these offset discs cut through tough ground and heavy residue in a single heavy pass instead of three light ones. Triple-sealed bearings and high-tensile pivot pins mean less time in the paddock and less time underneath the machine fixing it.

Benefits

What Your Operation Gets Back

One Pass, Ready to Plant

Cuts through residue and clods in one go, so you're not doubling back before the seedbed is ready.

Steady, Even Ground Work

Even disc engagement across the working width means a consistent finish, row after row.

Built to Last the Season

Strong, no-nonsense construction is designed to keep working when there's no time to waste.

The details

What makes it work

  • 01

    Heavy Disc Weight

    Up to 3,650kg of disc weight, among the heaviest in its class, keeps the blades cutting into hard, stony country instead of riding over it, so one pass does the job.
  • 02

    Hydraulic Gang Adjustment

    A hydraulic ram sets the gang angle on the go, so you can adjust how aggressively the discs cut as soil conditions change, without stopping or reaching for a spanner.
  • 03

    Rear Draw Bar

    A standard rear draw bar tows harrows or rollers behind the discs, combining cultivation and finishing in one pass to save fuel, hours and soil structure.
  • 04

    Triple-Sealed Willett Bearings

    Willett bearings in SG iron housings are triple-sealed against dirt and water and need no greasing, so you spend less time under the machine and more time working.
  • 05

    9mm RHS Frame & 4140 Axles

    A 9mm wall RHS frame, 50mm high-tensile pivot pins and 40mm square 4140-grade axles carry the strain of heavy ground work season after season without flexing.

Expert advice

Tips from the Rata team

  • Choose blade size and disc count to match your soil type and horsepower, heavier country needs the bigger blades and the extra weight behind them.

Customer story

Proven in the paddock

Hear from the cropping farmers who put Rata equipment to work every day.

“I'm impressed with the results these discs give, they contour the ground & hills while staying in the ground actually disking, even in this harder, dryer stony ground so I'm pretty pleased.”

Ben Scott, Contractor, Oamaru, NZ
