The Big Country Strip RZM is designed with maintenance-free rubber torsion. The rubber torsions are on the lead coulter, twin coulter, and row cleaner. Wako introduced this change in 2014 with no infield failures to date.

Wako’s 3 Coulter Zone/Strip-Till System creates a worked solid sized zone. The zone/strip width is easily adjustable to 5-10 inches and a depth of up to 10 inches versus the narrow two-inch strip of the single coulter system. By adjusting the width of the zone, the depth of the knife, and the travel speed, you’ll be able to change the soil size to create the best seedbed structure for precision planting.
