The ripping member is positionable in a selected working position and orientation by adjustment of the frame. The ripping member is movable relative to the frame to cause reciprocating movement of the engagement head at least partially longitudinally. A tilt adjustment cylinder orients the ripping member in the selected orientation. A vibrator mechanism operatively connected to the ripping member is activatable to cause reciprocating movement of the engagement head at least partially longitudinally. A control system includes a pressure sensor fluidically connected to the tilt adjustment cylinder and the pressure sensor determines a pressure thereof. The control system is configured to alter an operational state of the vibrator mechanism based on the pressure being above or below a threshold pressure. ## Claims ### Claim 1 A ripping mechanism for a vehicle, comprising: a support frame; a ripping member having an engagement head that is configured for plowing a groove in the ground, wherein the ripping member is positionable in a selected working position and working orientation by adjustment of the support frame, and wherein the ripping member is movable relative to the support frame to cause reciprocating movement of the engagement head at least partially longitudinally; a tilt adjustment cylinder operable to orient the ripping member in the selected orientation; a vibrator mechanism operatively connected to the ripping member and activatable to cause reciprocating movement of the engagement head at least partially longitudinally; and, a control system including a pressure sensor fluidically connected to the tilt adjustment cylinder, the pressure sensor configured to determine a pressure of the tilt adjustment cylinder, wherein the control system is configured to alter an operational state of the vibrator mechanism based on the pressure being above or below a threshold pressure. ### Claim 2 (depends on 1) The ripping mechanism as claimed in claim 1, wherein altering the operational state comprises deactivating the vibrator mechanism and the control system is configured to deactivate the vibrator mechanism based at least in part on if the pressure is below a lower threshold pressure. ### Claim 3 (depends on 1) The ripping mechanism as claimed in claim 1, wherein altering the operational state comprises activating or permitting activation of the vibrator mechanism and the control system is configured to activate or permit activation of the vibrator mechanism based at least in part on if the pressure is above an upper threshold pressure. ### Claim 4 (depends on 2) The ripping mechanism as claimed in claim 2, wherein altering the operational state further comprises activating or permitting activation of the vibrator mechanism and the control system is configured to activate or permit activation of the vibrator mechanism based at least in part on if the pressure is above an upper threshold pressure that is the same pressure as the lower threshold pressure. ### Claim 5 (depends on 2) The ripping mechanism as claimed in claim 2, wherein altering the operational state further comprises activating or permitting activation of the vibrator mechanism and the control system is configured to activate or permit activation of the vibrator mechanism based at least in part on if the pressure is above an upper threshold pressure that is higher than the lower threshold pressure. ### Claim 6 (depends on 3) The ripping mechanism as claimed in claim 3, wherein the control system is configured to have an automatic mode wherein the control system is configured to activate the vibrator mechanism based at least in part on the pressure and a manual mode wherein the control system is configured to permit activation of the vibrator mechanism based at least in part on the pressure. ### Claim 7 (depends on 1) The ripping mechanism as claimed in claim 1, wherein the control system further comprises one or more accumulators. ### Claim 8 (depends on 1) The ripping mechanism as claimed in claim 1, wherein the control system further comprises an electronic controller. ### Claim 9 (depends on 1) The ripping mechanism as claimed in claim 1, wherein the control system further comprises a timer to determine whether or not to alter the operational state of the vibration mechanism. ### Claim 10 (depends on 1) The ripping mechanism as claimed in claim 1, wherein the pressure fluctuates in a range with a peak pressure within the range that changes depending on operations of the ripping mechanism, and wherein altering the operational state comprises activating or permitting activation of the vibrator mechanism, and wherein the control system is configured to activate or permit activation of the vibrator mechanism based at least in part on if the peak pressure is above an upper threshold pressure. ### Claim 11 (depends on 10) The ripping mechanism as claimed in claim 10, wherein altering the operational state further comprises deactivating the vibrator mechanism and the control system is configured to deactivate the vibrator mechanism based at least in part on if the peak pressure is below a lower threshold pressure. ### Claim 12 (depends on 1) The ripping mechanism as claimed in claim 1, wherein the pressure fluctuates in a range with a peak pressure within the range that changes depending on operations of the ripping mechanism, and wherein altering the operational state comprises activating or permitting activation of the vibrator mechanism, and wherein the control system is configured to activate or permit activation of the vibrator mechanism based at least in part on if an average of the peak pressure is above an upper threshold pressure. ### Claim 13 (depends on 1) The ripping mechanism as claimed in claim 1, wherein altering the operational state comprises permitting manual activation of the vibrator mechanism, and wherein the control system is configured to permit manual activation of the control system based at least in part on if the pressure is above an upper threshold pressure.
