Bengal Tools Ltd, a Shrachi Group company, has announced plans to strengthen its marketing and technology tie-up with Zhejiang Sifang Group, Chinas largest manufacturer of power tillers. The $120-million Chinese corporation, which is engaged in agricultural machinery, export-import trade, and real estate development, has not ruled out a manufacturing joint venture with Bengal Tools, as well. The group sees huge potential for its pull-drive power tillers in India, highly suitable for rice cultivation in small-sized lands. Lin Guangpin, president, Zhejiang Sifang Group Corp, said that the Sifang-made Shrachi power tillers, marketed by Bengal Tools Ltd, had recorded a 30 per cent sales growth, and that Bengal Tools was now among the top international dealers of Sifang. Bengal Tools has two assembling units, one in Dum Dum-Kolkata, and the other in Bangalore. The Sifang Group Corp, founded in 1961, is one of the leading Chinese enterprises, which specialises in manufacture of walking tractors and other farm implements.
