Rotary Tiller or Disc Harrow? Choose the Right for Your Farm

• December 07, 2024

Preparing the soil is an essential step before planting any of the crops. Farmers and gardeners use various soil preparation tools to make the soil soft and ready for seeds.

Two popular tools are the rotary tiller and the disc harrow. But which one is the best tool for soil preparation? Let’s explore these farming implements to understand their differences and determine which works best for your needs.

What Is a Rotary Tiller?

Rotary tiller also known as a rotavator is an agricultural machinery that breaks up and turns the soil using rotating blades. It is attached to a tractor or can be operated as a standalone machine. The rotating blades dig into the soil, making it soft, loose, and ready for planting.

Key Features of a Rotary Tiller:

• It works well for mixing soil.
• The implement can easily handle small roots and weeds.
• It’s ideal for gardens, small farms, and areas where detailed soil preparation is needed.

What Is a Disc Harrow?

A disc harrow is another essential gardening equipment and farming tool. It uses rows of metal discs to cut, mix, and smooth the soil, usually pulled by a tractor. The discs break the soil into smaller pieces, making it easier for seeds to grow.

Key Features of a Disc Harrow:

• It is better for larger fields.
• It works well for breaking hard, dry soil.
• It’s commonly used after ploughing to level the ground.
