More Information About 3D Model :
The Mild Steel Cage Wheel, often referred to as a skeleton wheel, paddle wheel, or lattice wheel, is a specialized auxiliary traction device designed for use on agricultural tractors operating in terrains characterized by high moisture content, low soil bearing capacity, or excessive mud accumulation, such as rice paddies (wetland agriculture) or flooded fields.

### Nomenclature and Purpose

The descriptor "METAL MILD STEEL IRON CAGE WHEEL TRACTOR TYRE TIRE RIM SPADE LUG" defines its construction and function: it is a fabricated metal assembly, typically constructed from economical and durable **mild steel** (low-carbon steel) or structural iron, engineered to be mounted either concentrically over a standard pneumatic **tractor tire and rim** or alongside it (as a dual system). Its primary purpose is twofold: to significantly increase the overall contact area (improving flotation and reducing ground pressure), and to utilize robust peripheral elements, known as **spade lugs**, to maximize propulsive force.

### Design and Construction

The cage wheel consists of several integrated components:

1. **Central Attachment Rim:** A circular structure designed to affix securely to the standard tractor wheel rim or hub. This ensures alignment and transfers torque efficiently.
2. **Caged Framework:** The main body is characterized by an open, skeletal framework—the "cage." This design minimizes weight while preventing the entrapment and buildup of large masses of mud, which would otherwise negate the traction benefits. Radial spokes or structural members connect the inner attachment rim to the outer circumference.
3. **Spade Lugs:** These are the critical traction-enhancing elements. Fabricated from steel plate, the lugs are typically angled, shovel-like projections resembling grousers or paddles. They are robustly welded or bolted to the outer circumference of the cage framework, arranged circumferentially around the wheel’s periphery. The angle and depth of these lugs are carefully calibrated to ensure effective soil *********** and maximization of the soil’s shear strength upon rotation.

The mild steel construction provides the necessary rigidity and resistance to abrasive wear, essential for operation in waterlogged and soil environments.

### Operational Mechanics

The cage wheel significantly alters the interaction between the tractor and the ground surface, addressing key limitations of conventional pneumatic tires in soft soils:

1. **Flotation Enhancement:** By extending the diameter and distributing the tractor's weight over the much larger footprint created by the open cage structure, the average ground pressure (bearing stress) is drastically reduced. This prevents the tractor from sinking deeply into the soft terrain.
2. **Traction Augmentation (Shear Strength Utilization):** Unlike pneumatic tires, which rely on tread friction and deflection, the spade lugs penetrate the soft surface layer. During rotation, these lugs act as specialized paddles, engaging the underlying cohesive soil structure and utilizing the soil’s internal shear strength to generate powerful forward thrust (drawbar pull). The mild steel lugs resist deformation and abrasion far better than rubber treads in extreme conditions.
3. **Mud Clearing:** The open, "caged" structure allows water and mud to pass through the wheel easily, preventing the buildup of material that would otherwise create a slick, non-functional surface (the phenomenon known as ‘puddling’ or ‘clogging’).

Cage wheels are typically used as secondary attachments and are often removed when the tractor is operated on dry fields or paved roads, as the lugs are highly destructive to hard surfaces. They are an indispensable tool for intensive cultivation practices in regions reliant on wetland farming, particularly for harrowing, puddling, and transplanting operations in rice cultivation.
