**Attached Single Furrow Plow Blade Mould Mold Board Hand Tractor**

The attached single furrow plow blade, commonly referred to by its primary components as a mould board (or mold board) plow, is a specialized primary tillage implement designed for mechanical linkage to a two-wheeled, pedestrian-controlled agricultural machine, known colloquially as a hand tractor or walking tractor. This assembly serves as the fundamental mechanism for soil preparation in small-scale farming operations globally, particularly those characterized by intensive cultivation, limited capital, or difficult terrain.

### Classification and Context

This implement is classified as a mounted primary tillage tool, as it is rigidly secured to the hand tractor’s chassis or universal hitch point, deriving both motive power and vertical control from the machine. Unlike trailing implements, the attached nature of this plow allows the operator precise control over depth and draft angle through the tractor’s handles and associated stabilizing systems. Its designation as a "single furrow" plow indicates that the implement is designed to cut, lift, and invert one strip of soil (the furrow slice) per pass, contrasting with multi-bottom plows used on larger conventional tractors.

### Design and Components

The functional core of the implement is the plow bottom, a precisely engineered unit comprising four principal working parts:

1. **Plow Share (Blade):** The hardened, pointed cutting edge that penetrates the soil and horizontally slices the furrow slice from the subsoil. It is designed to withstand significant abrasion and impact forces.
2. **Mould Board (Mold Board):** The primary component responsible for inversion and pulverization. It is a convex, helical surface designed to receive the soil slice from the share, lift it, gradually turn it over (typically 135–150 degrees), and discharge it. The curvature of the mould board dictates the degree of soil turning and mixing achieved.
3. **Landside:** A flat, rigid plate that runs along the wall of the furrow (the landside wall). It counteracts the lateral thrust created by the turning action of the mould board, stabilizing the plow bottom and ensuring the maintenance of furrow width and depth.
4. **Frog (Standard):** The central casting or frame structure to which the share, mould board, and landside are bolted. The frog itself is then secured to the implement frame that connects to the hand tractor’s hitch mechanism, often incorporating adjustments for regulating the angle of *********** (****) and the horizontal plane.

The entire assembly is typically constructed of high-carbon steel alloys or specialized wear-resistant steel to ensure longevity under abrasive soil conditions.

### Operational Function and Tillage Quality

The primary function of the single furrow mould board plow is preparatory tillage for planting. During operation, the forward motion of the hand tractor drives the plow bottom through the soil, achieving several critical effects:

* **Inversion:** The turning of the soil buries surface crop residue, weeds, and pathogens, facilitating decomposition and disease control.
* **Aeration:** The lifting and shattering of the soil improves porosity, allowing better water infiltration and root growth.
* **Seedbed Preparation:** The action breaks up large clods, though secondary tillage (e.g., harrowing) is usually required to achieve a fine seedbed.

The hand tractor’s low operational speed and high torque are well-suited for maintaining consistent draft force, crucial for effective soil turning. The single furrow design maximizes maneuverability in small, irregularly shaped fields and terraced landscapes where larger equipment is impractical.

### Significance in Agriculture

The attached single furrow mould board plow for hand tractors represents a crucial step in the mechanization ladder for developing economies and smallholder farms. It offers an efficient alternative to manual or animal-drawn plowing, significantly reducing labor intensity and increasing the speed of field preparation. Its compact size, relatively low purchase and maintenance cost, and ease of attachment to widely available two-wheeled tractors make it a globally significant component of subsistence and semi-commercial agriculture.
