Types of Tillage Discs by Kelly Tillage


When it comes to preparing the soil for planting, farmers have been relying on tillage discs for decades. These powerful tools come in various shapes, sizes, and designs, each with unique benefits and drawbacks.

From traditional ploughs to high-tech discs, the world of tillage equipment is constantly evolving, making it essential for farmers to stay up-to-date on the latest advancements to optimise their yield and maximise their profits.

In this blog, we’ll discuss the various types of tillage discs by Kelly Tillage used for farming. We’ll focus solely on the different types of discs we offer.

It’s important to note that the effectiveness of these discs can vary greatly depending on various factors, including soil type, crop production, temperature, and other environmental factors.

For example, a specific disc type might work best for heavy clay soils but may be less effective on sandy soils, and vice versa. In dry conditions, a disc may struggle to penetrate the soil and create the desired seedbed, while in wet conditions, it may cause excessive soil compaction.

Types of Tillage Discs

We are here with disc types Kelly Tillage offers with specific features and specifications. These are popularly used for different purposes. So, let’s get to know them. 

The K4 Disc Chain

The K4 Disc Chain is a special tillage disc designed for enhanced weed control, especially in loam soils.

According to reports from farmers who have used this method, the K4 Disc Chain has effectively reduced weed density by over 90%.

The K4 Disc Chain has been designed with a focus on simplicity to ensure ease of use for farmers. Its closer disc spacing creates an overlap that enables full soil coverage even at ultra-shallow working depths. Additionally, the smooth disc face minimises residue build-up in wet conditions, further enhancing its efficiency.

Furthermore, the bolt-on design of the K4 Disc Chain enables easy addition or removal of links from the chain without requiring disassembly. These features combined make the Disc Chain a sturdy, straightforward, and dependable tool for farmers.
