One-pass tillage tool New to Quinstar's line of conservation tillage tools is the Field Finisher, which is offered in three sizes: 27, 32 and 42 ft. Hydraulically controlled disc gangs slice and size crop residue and mix the soil; spring-reset shanks provide additional tillage, working in most soil conditions. The specially designed wheels on the Mulch Treader attachment invert weeds, incorporate chemicals and level the soil. Finishing attachments include a three-row tine harrow, followed by a rolling basket for added leveling and smoothing. Prices start at $34,545. Contact Quinstar Equipment Co., Dept.
