SHREW wheeled mini tractor▪

1. The mission of the project

Mini tractors have become a universal tool for millions of users, but most existing models have remained virtually unchanged over the past decades. They are characterized by a high center of gravity, narrow track, poor stability, and conservative architecture.

The SHREW project is to create a modern universal mini-tractor of a new generation, which will become a professional tool for daily work in any climatic conditions.

SHREW is designed to work:

• in farms;
• in suburban and household plots;
• in public utilities;
• in plant nurseries;
• in greenhouses;
• on the territories of cottage settlements;
• in parks;
• at sports facilities;
• at airports;
• in industrial enterprises;
• on construction sites.

Thanks to the new layout, SHREW has a number of fundamental advantages:

• significantly lower center of gravity;
• increased width relative to the length;
• high lateral stability;
• better stability on the slopes;
• increased traction force;
• better cross-country ability;
• greater operator safety.

By its architecture, SHREW occupies an intermediate position between traditional mini tractors and industrial utility vehicles.

2. The philosophy of the SHREW project

The name SHREW reflects the nature of the machine.

The shrew is one of the most active and efficient animals of its size. Despite its small size, it has tremendous performance, high endurance and the ability to work almost continuously.

These qualities have become the basis of the brand's philosophy.

Basic principles of SHREW:

• Maximum performance with minimum size.
• Simplicity of construction.
• Reliability is higher than complexity.
• Functionality is more important than decorativeness.
• Engineering is more important than marketing.
• Modern industrial design.
• Long service life.
• Easy maintenance.

The SHREW is a professional work tool, not a decorative technique.

3. General concept and design of RenderWorks Industrial Design

The main idea of the project is to completely rethink the appearance of a traditional mini tractor.

Instead of a large number of plastic elements, an architecture built of large flat metal panels is used.

Main design features:

• wide body;
• low hood line;
• elongated silhouette;
• wedge-shaped front part;
• the front panel resembles the face of a shrew;
• minimum number of decorative elements;
• modern LED optics;
• concise geometric shapes;
• pronounced industrial aesthetics.

Almost all exterior panels are designed for production by:

• laser cutting;
• flexible;
• welding;
• powder coating.

This significantly reduces the cost of manufacturing.

Visually, SHREW is closer to modern industrial machinery than to classic agricultural tractors.

4. Engineering solutions

The project is built around modern engineering principles.

Low center of gravity

The engine is positioned as low as possible.

The transmission is placed between the axles.

The fuel tank is located inside the frame.

This significantly increases the stability of the machine.

Wide base

Compared to most analogues, SHREW has:

• large width;
• increased track;
• lower height.

It improves:

• stability;
• the clutch;
• security;
• operator's comfort.

Simple power structure

The supporting structure is a welded spatial frame.

They are installed on it:

• the engine;
• transmission;
• body panels;
• hydraulics.

Modular body

All panels are independent.
Any element can be replaced separately.
This significantly reduces the cost of repairs.

Unification

The maximum number of components is unified between the modifications of the family.

The uniform ones are used:

• panels;
• frame;
• cabin;
• hydraulics;
• electronics.

Modern ergonomics

The workplace provides:

• good review;
• low vibration level;
• comfortable fit;
• easy access to controls.

Modern lighting technology

Used:

• LED headlights;
• LED work light;
• modern light alarm system.

5. Key advantages over existing machines

Compared to most traditional mini tractors, SHREW offers a number of design advantages.

Geometry

✔ Significantly lower

✔ much wider

✔ More stable

Manageability

• passes the slopes better;
• less chance of tipping over;
• more stable when working with front-end equipment.

Passability

Thanks to the wide base and optimal weight distribution:

• works better on loose ground;
• moves more confidently in the snow;
• works more effectively on moist soil.

Traction qualities

The low center of gravity allows you to realize a large thrust force without loss of stability.

Production

The design is focused on:

• laser cutting;
• flexibility;
• robotic welding.

This reduces the cost of production.

Maintenance

All nodes have free access.

The hood opens completely.

The panels can be removed independently.

Modern design

The exterior corresponds to the industrial technology of the 21st century and compares favorably with traditional tractors.

8. Project Outcome

SHREW is not just another mini tractor, but a modern engineering platform designed to meet the requirements of the 21st century. Due to its wide and low layout, the machine has a lower center of gravity, better stability, high traction and increased cross-country ability compared to most existing analogues. The simple modular design, focused on laser cutting and metal bending, makes SHREW technologically advanced, economical and easy to maintain.

The project combines modern industrial design, thoughtful ergonomics and a scalable architecture that allows you to create a whole family of machines for agriculture, utilities, construction and industry. SHREW is a new universal compact technology platform where engineering rationality, reliability and efficiency are the main values.
