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.”
“I'm impressed with the results. They contour the hills and stay in the ground actually disking, even in harder, drier, stony ground.”
“Being a heavier disc, about three and a half tonne, they bite in and get into the harder ground better.”
“You can keep adjusting the cut on the hydraulics, which is awesome. You can do it on the go.”
“As a contractor, you want to be able to say 'yep, no worries, I'll be able to do that.' This machine has proven I can almost guarantee that.”
“All the bearings on the machine are non-greasable, so everything's enclosed.”
“From contacting the Rata dealer to when they were delivered, it's been prompt. Brilliant service.”
“Great product, great machine. Looking forward to dealing with them further in the future.”
“You want to be able to accommodate all the conditions, and these seem to be providing that, so I'm pretty happy with what they do.”
