September 24, 2015
Brian Perkuhn, vice president of sales with Summers Mfg., introduces the VRT 3530 variable-rate tillage machine at the 2015 Farm Progress Show. The tool allows you to adjust tillage aggressiveness on the go.
It offers conventional tillage performance with the ability to switch to less mixing in areas where you want to leave more residue on the surface.
