ABSTRACT:
Press wheel gangs are pivotally connected to an implement frame by an upright pivot bracket which permits each gang to rock about both a fore-and-aft extending axis and an axis transverse to the forward direction. A pivot at the lower end of the bracket and above the forward central portion of the gang permits the gang to rock about the fore-and-aft axis to move over small obstacles and uneven terrain. The entire gang can rock upwardly about the transverse axis over larger obstacles or extremely rough terrain to eliminate extreme stressing of the gang press wheels and to assure uniform soil-firming characteristics. A compression spring assembly connected between the frame and the upper end of the bracket yieldingly biases the gang into soil-firming relationship with the ground.
