尼泊尔采购需求：田间起垄机、起垄机、土壤起垄机

I am interested in your agricultural machinery that significantly enhances efficiency compared to manual labor. Specifically, I'd like to know more about the ridger model that promises to improve work output by 40-50 times. Please provide detailed specifications, pricing, and estimated delivery times, including any customs considerations. If you have different options available or any promotions, feel free to include that info as well. Looking forward to your prompt response!
