Tarran Tiller

Gardening is a deep-rooted passion in the United Kingdom. In 2024, 55% of British adults (around 18.1 million people) said they gardened as a regular hobby. Private green spaces are an integral part of British life: 78% of adults have access to a private garden, and 62% of them use it to grow plants, flowers, or ornamental trees. Tarran Tiller emerges as a concrete response to two key needs: improving efficiency in preparing the soil of domestic flower beds and reducing physical effort for gardening enthusiasts. It aims to make gardening more accessible and enjoyable, in perfect harmony with the cultural connection that the British have with green spaces.

Tarran Tiller is a compact electric tool designed to loosen and aerate the soil in home gardens. Designed for enthusiasts seeking a balance between efficiency and comfort, it combines clean design, sturdy materials, and intuitive functionality, making it perfectly suited to private gardens.

Ergonomic Design

Tarran Tiller has been carefully designed with a strong focus on ergonomics and user comfort. The rear handle integrates both the activation button and the safety switch, ensuring intuitive and secure operation. A second front handle provides additional stability and balance while working the soil.

Both grip areas feature a rubber coating with a parametric pattern generated in Grasshopper, improving slip resistance while adding a distinctive aesthetic detail to the product.

Balanced Weight Distribution

The Tarran Tiller has been engineered to achieve an optimal balance between the rear motor block and the front working section.

This distribution of weight minimizes strain on the user’s arms and shoulders, allowing for smoother control and prolonged use without discomfort. By aligning the center of gravity between the two main components, the tool feels stable and responsive, enhancing both precision and safety during soil cultivation.

Adjustable Handle Mechanism

Tarran Tiller is equipped with an adjustable tubular handle that can be extended or shortened through a sliding mechanism. This feature allows users to customize the length of the tool according to their height and working posture, ensuring greater comfort during operation.

The central front handle is directly connected to the adjustable tube, maintaining stability and control regardless of the chosen configuration. This flexibility makes Tarran Tiller adaptable to different users and gardening scenarios, improving overall ergonomics and ease of use.

Safe Activation System

Tarran Tiller integrates a dual-button safety system within the rear handle. To activate the tool, the user must press both the upper activation button and the lower safety button simultaneously.

This two-step mechanism prevents accidental startups, ensuring that the tiller only operates under intentional control. By combining safety and intuitive design, the system offers peace of mind while maintaining ease of use during gardening tasks.

Side protections

The central handle of the Tarran Tiller also serves as a protective support when the device is placed on its side.

Thanks to its protruding shape, the handle keeps the tool slightly elevated, preventing the outer surfaces of the housing from coming into direct contact with the ground. This design detail helps to avoid scratches and wear on the body, extending the product’s durability and preserving its clean aesthetic.

Airflow pattern

To ensure proper ventilation, the upper sections of the housing above the motor and battery compartments feature a perforated hexagonal pattern. This design allows for efficient airflow, which is essential to keep internal components cool and maintain consistent performance during operation.

The pattern is also aesthetically coherent, as it echoes the same geometry used on the rubber grips of the handles.

It was developed parametrically in Grasshopper, combining technical efficiency with visual continuity and reinforcing both the identity and reliability of the Tarran Tiller.

Prototyping and Validation

The development of Tarran Tiller included the creation of physical prototypes to validate the design beyond the digital environment. These models were used to test ergonomics, handle positioning, and weight distribution, confirming the practicality of the design solutions.
