Field Wave - Shear bolt

More Pasture Per Dollar You Spend on Fert
This subsoil aerator's shear-bolt protection means a $2 bolt shears off when a leg hits something solid, instead of bending metal you'd need a welder for. The double-bar V-frame still aerates compacted soil at full depth, just with a repair bill you can fix yourself in the paddock.

Field Wave - Shear bolt

Benefits

What Your Operation Gets Back

More Growth Per Dollar Spent

Opens the soil so fertiliser is absorbed by roots instead of wasted to runoff, getting more value from every spread.

Water, Oxygen Reach Roots

Permeable soil lets water soak in and oxygen flow freely, feeding the biology that drives real growth.

Proven Yield Gains

Documented trials show pasture dry matter up by as much as 28% once compaction is properly broken up.

The details

What makes it work

  • 01

    V-Frame Design

    The double-bar V-frame breaks through compacted soil at depth, improving aeration while making the implement easier to pull.
  • 02

    Shear Bolt Leg Protection

    A shear bolt protects each leg when it strikes an obstruction, preventing costly damage and allowing quick repairs in the paddock.
  • 03

    Auto-Reset Springs

    An optional upgrade that allows the legs to reset automatically after hitting an obstruction, reducing downtime and keeping you moving.
  • 04

    Wear-Protected 16mm Legs

    16mm legs with attached shin guards are bolted into gusseted mounts on a heavy main frame, resisting wear so the aerator keeps working season after season.
  • 05

    Self-Cleaning Rear Roller

    The rear roller sets working depth and runs in a sealed flange bearing, with a scraper that keeps it clean for consistent results in wet, sticky soil.

Expert advice

Tips from the Rata team

  • Auto-reset springs can be retrofitted later if you decide you want them, you're not locked into shear-pin operation forever.

Customer story

Proven in the paddock

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

“It does the cracking down below. It leaves all the clay down the bottom and doesn't bring anything up. I found that to be very good.”

Tim Barry, Cropping farmer, Victoria, AUField Wave owner

Common questions

We've got your back

Q: What's the difference between a shear bolt aerator and a auto-reset aerator? A: The Rata Shear Bolt Field Wave Aerator uses shear-bolts instead of auto-reset leaf-springs to protect the legs and frame in case of an underground obstruction. Springs can be retrofitted at a later date.
