The I-4200 combines residue mixing capabilities of the I-4100 with the field finish characteristics of the I-1200 or I-2200 (five-inch spaced models). The combination allows for excellent seedbed preparation and field finish, more residue coverage, thorough residue sizing, effective mechanical weed control, stronger performance in high-residue or wet conditions compared to compact discs or disc gang-style VT machines. The I-4200 is compatible with all Salford seeding and fertilizer application attachments, including SwitchBlade hydraulic shanks. This combines multiple operations into one pass, multiplying the productivity factor of the machine. The I-4200 may also be combined with Salford standard and Flex Finish harrow systems.
