Unverferth Manufacturing has broadened the available working width range of its Perfecta field cultivators, which can now be ordered in sizes from four to 40 feet. The company claims the Perfecta models blend tillage, levelling and finishing actions into one implement. The new, wider sizes use a floating wing design that can rise up to 15 degrees and lower by five degrees to follow field contours.
Three rows of high-clearance S-tines provide tillage up to six inches deep. There are three different tine styles on each of the models: the 10, 12 and 14. The model 10 uses 1¼-inch by ½-inch S-tines with 2¾-inch goosefoot shovels. The model 12 gets 1¾- x ½ -inch heavy-duty S-tines with four-inch sweeps for better penetration in heavier, unworked soils and rocky conditions. Heavy-duty, edge-bent tines are standard on the model 14.
Behind the tines, an adjustable levelling bar breaks up clods and levels the soil with a choice of spike or diagonal round teeth. A 12-inch diameter rolling basket then mixes and levels. Gauge wheels across the machine’s width maintain an even working depth.
Buyers can colour match their Perfecta to red or green tractors with a high-gloss powder coat.
