Front plowshare, part numbers 073250 and 073251, agricultural machinery.
The front plowshares 073250 and 073251 are core, easily worn components in agricultural tillage machinery, especially moldboard plows and high-speed reversible plows. As a key part of the plow assembly, this series of front plowshares typically works in conjunction with the rear plowshare, plowshare, and plowshare column to cut, break, and turn the soil. These two models feature a split design, designed to address the high replacement costs and inconvenient maintenance associated with traditional one-piece plowshares after partial wear. They are particularly suitable for high-speed tillage and complex operation environments in dryland soils.
The front plowshares 073250 and 073251, located above and behind the plowshare, are the main areas that bear the brunt of soil friction and impact. Their core functions are:
Assisting in soil entry and breaking up: Working in conjunction with the plowshare, they compress and break up the clods cut by the plowshare, reducing the workload on subsequent components.
Turning and covering: Through a specific curved surface, they smoothly lift and laterally turn up the broken soil, achieving deep coverage of stubble, weeds, and fertilizer, improving the soil's aggregate structure.
Split-type modular structure: It uses countersunk bolts to fix the plowshare (or plow column) for easy assembly and disassembly. Since the front plowshare wears faster than the rear plowshare during tillage, this split design allows users to replace only the severely worn front plowshare (such as 073250 or 073251) while retaining the good-condition rear plowshare and other components, thereby significantly reducing maintenance costs and downtime.
To cope with intense soil abrasion and complex stress environments, the front plowshares of models 073250 and 073251 are typically manufactured using materials with high hardness, high wear resistance, and good toughness. In accordance with modern agricultural machinery technology, these components are often made of high-quality steel (such as 65Mn manganese steel) through heat treatment or surface strengthening processes to ensure a long service life. Some high-end designs may also involve magnetic materials or special surface optimizations (such as concave composite curve shin blades) to further reduce tillage resistance, lower fuel consumption, and improve soil-throwing performance under high-speed operation.
This series of front plowshares is widely applicable to suspended moldboard plows, high-speed reversible plows, and other equipment配套 with large and medium-sized tractors. Whether used for deep plowing in autumn, tillage in spring, or stubble removal operations in heavy clay soils, black soils, or general dry fields, the 073250 and 073251 models, with their excellent curved surface design, ensure good maneuverability and tillage quality, making them ideal replacement parts for achieving "conservation tillage" and high-efficiency agriculture.
