Secondary Attachment for Work Vehicle

Abstract

A work vehicle comprising a frame supported by a ground engaging device. A boom assembly is coupled to the frame. A boom cylinder is coupled to the frame and the boom assembly. An attachment coupler is coupled to a distal portion of the boom assembly. At least one tilt cylinder is coupled to the boom assembly and the attachment coupler. A primary attachment is coupled to the attachment coupler. A secondary attachment is coupled to the primary attachment. The secondary attachment comprises a stand configured to move between a standing mode and a stored mode, wherein the stand automatically moves to the standing mode when it is decoupled from the primary attachment.

         2 . The work vehicle of  claim 1 , further comprising a receiver coupled to one of the primary attachment and the secondary attachment and a pin coupled to the other of the primary attachment and the secondary attachment, the receiver configured to couple to the pin, the receiver further configured to decouple from the pin in the standing mode. 
     
     
         3 . The work vehicle of  claim 2 , wherein the pin is decoupled from the receiver when a top of the primary attachment is positioned towards the surface. 
     
     
         4 . The work vehicle of  claim 1 , wherein the secondary attachment comprises a scarifier. 
     
     
         5 . The work vehicle of  claim 1 , wherein the primary attachment comprises a dozer blade. 
     
     
         6 . The work vehicle of  claim 1 , wherein the stand comprises a center of gravity positioned to move the secondary attachment to the standing mode when a top of the primary attachment is positioned towards the surface. 
     
     
         7 . The work vehicle of  claim 1 , wherein the stand comprises a center of gravity positioned to move the secondary attachment to the standing mode when a top of the primary attachment is positioned closer to the surface than where the top is positioned when the stand is in the stored mode. 
     
     
         8 . The work vehicle of  claim 1 , wherein in the stored mode the stand contacts the primary attachment. 
     
     
         9 . The work vehicle of  claim 1 , wherein the stand comprises at least two legs and each leg is coupled to the secondary attachment via a pin joint. 
     
     
         10 . The work vehicle of  claim 1 , further comprising a stop coupled to the stand, the stop configured to limit movement of the stand when moving from the stored mode to the standing mode. 
     
     
         11 . The work vehicle of  claim 1 , wherein the work vehicle comprises a compact track loader. 
     
     
         12 . A compact track loader comprising:
 a frame;   at least one ground engaging device coupled to the frame and configured to support the frame above a surface;   a boom assembly coupled to the frame;   at least one boom cylinder coupled to the frame and the boom assembly and configured to move the boom assembly;   an attachment coupler coupled to a distal portion of the boom assembly;   at least one tilt cylinder coupled to the boom assembly and the attachment coupler and configured to move the attachment coupler;   a primary attachment coupled to the attachment coupler; and   a secondary attachment coupled to the primary attachment, the secondary attachment comprising a stand configured to move between a standing mode and a stored mode, wherein the stand automatically moves to the standing mode when it is decoupled from the primary attachment.   
     
     
         13 . The compact track loader of  claim 12 , further comprising a receiver coupled to one of the primary attachment and the secondary attachment and a pin coupled to the other of the primary attachment and the secondary attachment, the receiver configured to couple to the pin, the receiver further configured to decouple from the pin in the standing mode. 
     
     
         14 . The compact track loader of  claim 13 , wherein the pin is decoupled from the receiver when a top of the primary attachment is positioned towards the surface. 
     
     
         15 . The compact track loader of  claim 12 , wherein the secondary attachment comprises a scarifier. 
     
     
         16 . The compact track loader of  claim 12 , wherein the primary attachment comprises a dozer blade. 
     
     
         17 . The compact track loader of  claim 12 , wherein the stand comprises a center of gravity positioned to move the secondary attachment to the standing mode when a top of the primary attachment is positioned towards the surface. 
     
     
         18 . The compact track loader of  claim 12 , wherein the stand comprises a center of gravity positioned to move the secondary attachment to the standing mode when a top of the primary attachment is positioned closer to the surface than where the top is positioned when the stand is in the stored mode. 
     
     
         19 . The compact track loader of  claim 12 , further comprising a stop coupled to the stand, the stop configured to limit movement of the stand when moving from the stored mode to the standing mode. 
     
     
         20 . A work vehicle comprising:
