SIGMA 4 was founded in 1975 by 3 associates who shared the same entrepreneurial vision: design, develop and promote new tools for agriculture.
In the '80s and '90s SIGMA 4 saw remarkable growth in both its company size and its market share on a national and international level.
SIGMA 4 progressively abandoned its artisan dimension while keeping the very same attention to the detail and its passionate approach.
The company entered the Gallignani Group in 2001: new production and sales synergies are exploited, helping its continuous expansion.
Today SIGMA 4 is a modern and well-structured company, which is able to meet all demands in terms of front end loaders.
Thanks to its 30-year-long co-operation with the tractor's Major Manufacturers, SIGMA 4 is a market leader in Italy and among the first 6 loader manufacturers on an international level.
These are our key concepts: Adaptability, Reliability and Ease of Fitting.
