An improved coulter assembly (10) includes a rotatable coulter blade (12) and a supporting assembly (14) having a parallel linkage arm assembly (34) and an active piston and cylinder assembly (58). The assembly (14) serves to maintain the blade (12) at a depth of at least about four inches, in order to prevent clogging of the assembly (10) during use. Another coulter assembly (110) includes a knife adjustment assembly (122) allowing selective vertical and angular adjustment of the knife (116) relative to the coulter blade (112).

A system for detecting material accumulation relative to disk gang assemblies of an agricultural implement includes an implement frame and a disk gang assembly supported relative to the implement frame. The disk gang assembly includes a toolbar coupled to the implement frame and a plurality of disks supported by the toolbar. The system also includes a load sensor configured to provide data indicative of an applied load through the disk gang assembly, and a computing system communicatively coupled to the load sensor. The computing system is configured to monitor the load applied through the disk gang assembly based on the data provided by the load sensor, compare the monitored load to a load threshold selected for the disk gang assembly, and determine that the disk gang assembly is in a plugged state when the monitored load differs from the load threshold.
