• Transmission: The transmission transfers power from the engine to the tines.

The working principle of rotary tillers involves the rotation of the tines, which dig into the soil and break it up, creating a loose and well-aerated seedbed.

C. Types of rotary tillers

There are two main types of rotary tillers:

1. Rear-tine tillers: Rear-tine tillers have the tines located behind the wheels, providing better stability and control.
2. Front-tine tillers: Front-tine tillers have the tines located in front of the wheels, making them more maneuverable in tight spaces.

D. Step-by-step walkthrough of using rotary tillers in soil cultivation

To use rotary tillers in soil cultivation, follow these steps:

1. Start the engine and engage the transmission.
2. Adjust the depth and speed settings according to the desired soil conditions.
3. Guide the tiller over the area to be cultivated, allowing the tines to dig into the soil.
4. Repeat the process as necessary to achieve the desired level of soil cultivation.

E. Real-world applications and examples of rotary tillers in agriculture

Rotary tillers are commonly used in various agricultural activities, including:

• Seedbed preparation: Rotary tillers are used to break up soil, mix organic matter, and create a fine, crumbly texture suitable for planting.
