First Claim
1. A work vehicle having an implement, comprising:
- a frame;
a boom arm assembly connected at one end to the frame;
an implement assembly pivotally connected to another end of the boom arm assembly and including the implement;
a first hydraulic implement cylinder connected to the implement assembly and positioned to pivotally rotate the implement relative to the boom arm assembly when a piston of the first implement cylinder is extended or retracted, the first hydraulic implement cylinder being connected to a first electrohydraulic valve for activating extension and retraction of the piston of the first implement cylinder; and
a controller connected to send control signals to activate the first electrohydraulic valve, wherein the controller sends a series of shaking control signals to alternately extend and retract the first implement cylinder to effect a shaking movement of the implement.

9. A work vehicle having an implement, comprising:
-
a frame;
a boom arm assembly connected at one end to the frame;
an implement assembly pivotally connected to another end of the boom arm assembly and including the implement;
a first hydraulic boom cylinder connected to the boom arm assembly and positioned to move the boom arm assembly relative to the frame of the work vehicle when a piston of the first boom cylinder is extended or retracted, the first hydraulic boom cylinder being connected to a first electrohydraulic valve for activating extension and retraction of the piston of the first boom cylinder;
a first hydraulic implement cylinder connected to the implement assembly and positioned to pivotally rotate the implement relative to the boom arm assembly when a piston of the first implement cylinder is extended or retracted, the first hydraulic implement cylinder being connected to a second electrohydraulic valve for activating extension and retraction of the piston of the first implement cylinder; and
a controller connected to send control signals to activate the first electrohydraulic valve and the second electrohydraulic valve, wherein the controller sends a series of shaking control signals to alternately extend and retract one of the first implement cylinder and the first boom cylinder to effect a shaking movement of either the implement or the boom arm assembly and the implement. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for controlling movement of a boom arm assembly and an implement pivotally connected to the boom arm assembly, the method comprising the steps of:
-
controlling movement of the boom arm assembly and the implement in a first operational mode using a controller that operates in the first operational mode and in a second operational mode, wherein movement control in the first operational mode effects smooth movements of the boom arm assembly and the implement in accordance with input signals received by the controller from control sensors;
switching the operation of the controller from the first operational mode to the second operational mode;
controlling movement of the boom arm assembly and the implement in the second operational mode using the controller, wherein movement control in the second operational mode effects shaking movement of the implement relative to the boom arm assembly in accordance with input signals received by the controller from one of the control sensors, wherein the shaking movement occurs about a pivotal connection between the boom arm assembly and the implement. - View Dependent Claims (16, 17, 18, 19)
