The agricultural conditions in northern and southern China differ markedly, with traditional rotary tillers often facing the dilemma of being ‘suited to dry fields but struggling in paddies’ or ‘adapted for paddies yet inefficient in dry fields’. This forces farmers to repeatedly purchase equipment, incurring additional costs while also having to deal with the hassle of switching between operations. The dual-purpose rotary tiller overcomes these limitations through its innovative ‘one machine for dual scenarios’ design. It efficiently handles paddy field cultivation while swiftly breaking up dry soil, establishing itself as a practical tool for enhancing farming efficiency.
Their core advantage stems from precise structural enhancements. Addressing the issue of muddy paddies causing wheel sinkage, these machines feature either widened anti-slip tyres or tracked undercarriages. By increasing ground contact area, they reduce ground pressure, enabling stable movement even in deep muddy paddies and preventing wheel sinking. Additionally, the machine incorporates anti-clogging rotary tiller blades. Crafted from wear-resistant alloy with specially heat-treated cutting edges, these blades efficiently shred rice stubble and weeds while preventing straw entanglement around the shaft, ensuring uninterrupted operation. When encountering hardened soil layers in dry fields, the machine allows adjustment of tillage depth (up to 30 centimetres) and blade shaft speed. This rapidly breaks up compacted soil to create a loose, uniform seedbed suitable for sowing dryland crops such as maize and wheat.
The dual-purpose tiller demonstrates outstanding performance in operational efficiency and cost control. Under traditional farming practices, farmers must purchase separate rotary tillers for paddy fields and dryland, increasing equipment investment costs by over 30% while requiring additional storage space. The dual-purpose model eliminates the need for extra modifications. By simply adjusting blades or walking components according to the tillage scenario, it achieves ‘dual-scenario operation with a single machine’. A single unit can complete tasks in both environments, directly reducing equipment acquisition costs by nearly half. Furthermore, the machine achieves an operational efficiency of 1-1.5 mu per hour, representing a 20%-30% improvement over traditional single-purpose models. Taking southern China's double-cropping rice cultivation as an example, farmers can complete the ploughing of 10 mu of paddy fields and the soil-breaking of 10 mu of dry land within three days using this equipment. This saves nearly two days compared to traditional machinery, significantly shortening the farming season.
From preparing paddy fields for seedling cultivation in southern rice-growing regions to readying dryland for sowing in northern areas, the dual-purpose rotary tiller adapts to diverse agricultural needs. Not only does it overcome the limitations of traditional rotary tillers in adapting to different scenarios, but its ‘one machine, multiple uses’ capability also reduces farmers' burdens and enhances operational efficiency. This makes it a vital piece of equipment for advancing large-scale, intensive agricultural production, empowering farmers to effortlessly tackle diverse cultivation scenarios and achieve ‘one machine for all farming needs in a single season’.
