Abstract: A tillage support includes a tool free adjustable tension leveling harrow bar that allows for an operator to adjust the tension of a leveling bar tool free. The tillage support includes a tensioning link coupled to a tensioning device. The tensioning link includes a plurality of coupling points. The tillage support includes a leveling bar mount arm with at least one coupling point and capable of being independently rotated about an axis. The leveling bar mount arm can be coupled to the tensioning link by a coupling link, and the coupling link can be adjusted by an operator tool free. The coupling link can engage any of the at least one coupling point of the leveling bar mount arm and the coupling points of the tensioning link, and the tension can be adjusted by engaging different coupling points with the coupling link.

Abstract: A utility vehicle or other utility device includes a hydraulic circuit that enhances operative capabilities of utility mechanisms with multiple hydraulic functionality. In some embodiments, multiple functionality can include powering of one or more hydraulic motor(s) and/or one or more hydraulic cylinder(s).

Abstract: A utility vehicle or other device for excavating soil or the like includes a utility mechanism, such as, e.g., a trencher, an auger or the like, with a motor-driven utility drum. In preferred embodiments, the motor is contained substantially entirely inside the drum. Preferably, the drive shaft is operatively connected to the drum to rotate the drum at a connection location that is displaced inward from ends of the drum. In some embodiments, the drive shaft is also preferably operatively connected to a second utility mechanism, such as, e.g., a trencher chain. In some embodiments, a planetary transmission is also located inside the drum.
