Weight where it counts

Up to 3,650kg total weight gets the blades into hard, dry and stony ground, including contoured hill country.

One pass, more done

A rear draw bar tows harrows or rollers behind, for quicker seedbed preparation.

Ready when time's tight

Triple-sealed Willett bearings, 50mm high-tensile pivot pins and a 9mm wall frame keep the discs working through the busy sowing window.

Sizing advice

Match the discs to your tractor

Disc weight and working width are matched to tractor horsepower, from 110hp for the 3.1m models up to 150hp for the 3.4m. Heavier discs penetrate harder ground, and blades come plain or scalloped to suit your conditions. Talk to your local dealer for their recommendation.

“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.”

What are offset discs used for?

Breaking up tough, heavy ground, whether it's stony, hard, dry or on contoured hill country. Paired with harrows or rollers, they're a reliable way to prepare ground for planting on cropping and sheep and beef farms.

Can I tow another implement behind the discs?

Yes. A rear draw bar lets you pull harrows or rollers in the same pass, and a hydraulic drawbar comes as standard.

What size tractor do I need for Rata offset discs?

The 3.1m models suit tractors from 110hp and 130hp, depending on blade size, and the 3.4m model suits 150hp and up.

Do the bearings need greasing?

No. Rata offset discs use triple-sealed Willett bearings in SG iron housings, designed to run without greasing.

Should I rip the ground before discing?

If the soil is compacted at depth, yes. A Field Wave Pre-Ripper breaks the hard pan first, so your discs can do their job properly instead of riding over the top.
