a tubular body comprising a longitudinal axis, a tip end, a dispensing nozzle defined at the tip end, and an interior channel in flow communication with the dispensing nozzle, wherein the tubular body is configured to be flexible;

an actuator configured to selectively modify an orientation of the tubular body;

an anchor coupled to a portion of the tubular body and configured to couple the tubular body to an attachment point within the machine and to allow the actuator to selectively modify an orientation of the tip end downstream of the anchor after the anchor couples the tubular body to the attachment point, wherein the attachment point is between two of the rotating blades to enable the rotating blades to move the tip end;

and

a reservoir in flow communication with the interior channel, wherein the reservoir is configured to supply a maintenance fluid to the tubular body for discharge from the dispensing nozzle,

wherein the actuator comprises at least one control channel extending along a length of the tubular body,

wherein the at least one control channel is selectively pressurized to selectively adjust the orientation of the tubular body.
