The perfection of the detail
A winning choice

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 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 market leader in Italy and among the first 6 loader manufacturers on an international level.
