Introduction
The document describes the SB1 series of hole diggers, a patented innovation in agricultural machinery designed for replanting vines and planting trees. It highlights the machine's ability to dig holes quickly and efficiently without compacting the soil, mimicking manual spade work.

Specifications
The SB1 series includes models such as SB1-40 and SB1-65, suitable for different row widths and vine distances. Key specifications include power requirements (22-51 kW), weight (330-360 kg), and operational dimensions.

Operating Procedure
The machine is positioned laterally to the desired digging point. The tractor hoist is lowered, and the digger is operated using side shift and angle adjustments. A single operator can manage all tasks, including old vine removal, with most of the worked soil remaining in the hole.

Features and Benefits
The SB1 digger can pass under vineyard wires without difficulty and efficiently remove old vines. It is designed for systems with row widths over 1.80 m and vine distances shorter than 0.9 m, making it versatile for various planting configurations.

Conclusion
The SB1 series represents a significant advancement in agricultural equipment, offering efficiency and ease of use for vineyard and tree planting operations.
