The 8m model HSD630 has been meticulously designed to enable the coverage of a maximum number of hectares in minimal time with a single machine and a tractor.
A rich history of tillage
The Agrico HSD630 series of high-speed discs has proved itself to be a trustworthy tillage partner over the years. Agrico introduced the first HSD in 2017 and it quickly became a resounding success among South African farmers. The initial models, available in widths of 2,5, 3,2, and 4m, were highly regarded in the industry. Agrico then introduced a 5m model and later a 6,3m model.
With the 8m model, the innovative Agrico team have developed their largest high-speed disc yet. This model is ideal for the 200-280kW tractor sector and has a folding frame with a unique push-to-fold cylinder configuration. The discs are the well-known 630mm notched type, protected by the trusted rubber reset mechanism.
What makes the Agrico high-speed disc stand out among its competitors?
Efficiency is key for farmers who aim to maximise their productivity while keeping labour and fuel costs in check. With the high-speed disc’s ability to operate at speeds of up to 16km/hour — almost double that of a traditional disc harrow — you can cultivate twice as many hectares in the same time frame, using nearly the same kilowatts and diesel consumption.
Johan Myburgh, head mechanical engineer at Agrico, emphasises how important it is for farmers to work efficiently and sow their crops as close to the ideal time as possible, often within a limited timeframe.
“With rising costs, farmers tend to switch to bigger tractors and bigger implements. Big machinery requires less labour, less maintenance, and gives the farmer better control. Farmers want to get through their hectares as fast as possible, and cultivate more hectares with less equipment,” he says. “This is precisely where the need for the 8m high-speed disc arose.”
Agrico understands the needs of Southern African farmers and its implements are manufactured locally to fit farmers’ needs exactly.
“The requirements of tools in Africa are different to those of Europe,” says Myburgh. “We know African conditions and know the challenges of the farmer. I drove a tractor even before I could walk properly.”
A design based on the success of previous models
The design process of the 8m high-speed disc was spearheaded by Cornel Fourie, a mechanical design engineer at Agrico and the chief designer behind the implement. He adds that the design builds on the success of its predecessors, particularly the 6,3m model.
“The 8m model is just an extension of the 6,3m model, so the design took less time as much of it was already in place. The two larger models go hand in hand with each other,” he says.
Key features of the Agrico high-speed disc
- The frame is foldable, with hydraulic control for easy transport.
- The disc is trailed, and not mounted on the tractor’s three-point, like the smaller models.
- The unique design of the larger discs, with spacing of 315mm between them, provides cost-effective operation with very good material flow.
- Fifty-four 630mm-diameter chopped discs reduce wear.
- Improved material flow is achieved with the help of the smart design and optimal spacing of the chopped discs.
- A robust frame ensures a durable tool with an extended life.
Discs that make a difference
“I think the big secret of the high-speed disc’s success is the aggressive angle at which the discs operate and the rubber springs to which they are attached,” says Fourie.
“The springs protect the discs, frame, and bearings. If a disc hits a stone, it breaks away and resets itself immediately. The work can continue uninterrupted and without damage.”
Furthermore, the rear roller, which assists in setting the working depth, contributes to a finely prepared seedbed and optimal mixing of the topsoil.
