Mechanical maize and bean planters in 2-row, 4-row and 6-row configurations are designed for accurate and efficient row planting, making them suitable for small to medium-scale farming operations. The number of rows determines the working width and field capacity, with adjustable row spacing typically ranging from approximately 30 to 90 cm to accommodate different crop requirements.

These planters use a mechanical seed metering system to ensure consistent seed placement, with adjustable in-row spacing generally ranging from about 5 to 50 cm depending on the crop and settings. Seed hoppers usually have a capacity of around 15 to 30 kg per row, allowing for continuous planting over larger areas. Some models also include fertilizer hoppers, typically ranging from 100 to 200 kg, enabling simultaneous seed and fertilizer application.

Mounted via a three-point linkage, mechanical planters are compatible with a range of tractors, generally requiring between 15 and 40 horsepower depending on size and configuration. Built for durability and ease of use, their weight can vary between approximately 200 and 800 kg. As with most agricultural equipment, specifications may vary depending on the manufacturer and configuration.
