Disclosed are various embodiments, aspects and features a multifunction, intelligent telescoping boom system. The system may comprise a hydraulic circuit with a continuous, circulating flow through a circuit that includes a hydraulic pump and a configurable valve bank. Valves in the valve bank may be designated to given components of any of a multitude of implement attachments. In this way, the continuous flow of hydraulic fluid through the valve bank may be distributed, via the valves, to the hydraulic components of implements. Hydraulic flow in excess of the demand created by the hydraulic components moves on through the valve bank and returns to the pump to continue the circulation. Also returning to the pump from the valve bank is any hydraulic fluid returning to the valve bank from the hydraulic components. Advantageously, because the system provides a continuous circulation of pressurized hydraulic fluid through the bank, implements with a mix of linear and rotating hydraulic components may be simultaneously powered from the same source of pressurized flow.

Disclosed is a seal assembly for a grading machine. The grading machine may include a machine body, a blade assembly, and a circle assembly supporting the blade assembly. The circle assembly may include a circle having a plurality of gear teeth. The grading machine may also include a drawbar assembly connecting the circle assembly to the machine body. The seal assembly may include a non-metallic seal component extending circumferentially around an inner circumference of the circle assembly for sealing the plurality of gear teeth.
