A hitch pin assembly includes a first pin having a longitudinal axis, a first end and a second end. A second pin extends from the longitudinal axis in close proximity to the first end. A third pin extends from the longitudinal axis in close proximity to the first end. A fourth pin extends from the longitudinal axis in close proximity to the second end. The first pin is configured to be received between a hitched position and an unhitched position in a member having an upper portion, a lower portion, and a hitch area positioned between the upper portion and the lower portion. Upon installation of the second pin and the fourth pin to the first pin, travel of the first pin along the longitudinal axis is restricted in each of opposed directions so that the hitch pin assembly cannot be removed from the member.

1. A vehicle comprising: a receiving member adjacent an end of a frame of the vehicle for receiving a hitch pin assembly; the hitch pin assembly comprising: a first pin having a longitudinal axis, a first end and a second end; a second pin extending substantially perpendicular to the longitudinal axis in close proximity to the first end; a removable third pin; a fourth pin extending substantially perpendicular to the longitudinal axis in close proximity to the second end; the first pin configured to be received between a hitched position and an unhitched position in the receiving member, the receiving member having an upper portion, a lower portion, and a void forming a hitch area positioned between the upper portion and the lower portion; wherein in the hitched position, the first pin extends at least substantially through the upper portion, through the hitch area, and at least partially into the lower portion; and the third pin is installed extending substantially perpendicular to the longitudinal axis engaging with the receiving member for maintaining the first pin in the hitched position; wherein in the unhitched position, the first pin is substantially maintained within the lower portion; wherein upon installation of the second pin and the fourth pin to the first pin of the hitch pin assembly in the member, travel of the first pin along the longitudinal axis is restricted in each of opposed directions so that the hitch pin assembly cannot be removed from the member. 2. The hitch pin assembly of claim 1, wherein an angular orientation with respect to the longitudinal axis of the first pin does not change between the hitched position and the unhitched position. 3. The hitch pin assembly of claim 1, wherein in the hitched position, the first end of the first pin is secured substantially beneath a first surface of the upper portion of the member. 4. The hitch pin assembly of claim 1, wherein in the unhitched position, the second end of the first pin is secured substantially above a second surface of the lower portion of the member. 5. The hitch pin assembly of claim 1, wherein openings formed in the upper portion and the lower portion of the member include a slot to receive the second pin. 6. The hitch pin assembly of claim 1, wherein upon installation of the third pin in the first pin, the third pin supports the first pin in the hitched position. 7. The hitch pin assembly of claim 6, upon removal of the third pin from the first pin, the second pin supports the first pin in the unhitched position. 8. The hitch pin assembly of claim 1, wherein the fourth pin limits movement of the first pin in the longitudinal direction, preventing removal of the first pin from the lower portion of the member. 9. The hitch pin assembly of claim 1, wherein the second pin is a spring pin. 10. The hitch pin assembly of claim 1, wherein third pin is a tethered quick release pin. 11. A hitch pin assembly comprising: a first pin having a longitudinal axis, a first end and a second end;a second pin extending substantially perpendicular to the longitudinal axis in close proximity to the first end;a third pin extending substantially perpendicular to the longitudinal axis in close proximity to the first end;a fourth pin extending substantially perpendicular to the longitudinal axis in close proximity to the second end;the first pin configured to be received between a hitched position and an unhitched position in a member having an upper portion, a lower portion, and a hitch area positioned between the upper portion and the lower portion;wherein in the hitched position, the first pin extends at least substantially through the upper portion, through the hitch area, and at least partially into the lower portion;wherein in the unhitched position, the first pin extends through the lower portion;wherein upon installation of the second pin and the fourth pin to the first pin of the hitch pin assembly in the member, travel of the first pin along the longitudinal axis is restricted in each of opposed directions so that the hitch pin assembly cannot be removed from the member; andwherein an opening formed in the member to receive the first pin is at least partially located beneath a hood of a work vehicle. 12. A work vehicle comprising: a motor associated with selectable movement of a frame by operator controls;the frame structurally carrying a cab structure and a member adjacent one end of the frame for selectable towing by a hitch pin assembly comprising: a first pin having a longitudinal axis, a first end and a second end;a second pin extending substantially perpendicular to the longitudinal axis in close proximity to the first end;a third pin extending substantially perpendicular to the longitudinal axis in close proximity to the first end;a fourth pin extending substantially perpendicular to the longitudinal axis in close proximity to the second end;the first pin configured to be received between a hitched position and an unhitched position in a member having an upper portion, a lower portion, and a hitch area positioned between the upper portion and the lower portion;wherein in the hitched position, the first pin extends at least substantially through the upper portion, through the hitch area, and at least partially into the lower portion;wherein in the unhitched position, the first pin extends through the lower portion;wherein upon installation of the second pin and the fourth pin to the first pin of the hitch pin assembly in the member, travel of the first pin along the longitudinal axis is restricted in each of opposed directions so that the hitch pin assembly cannot be removed from the member. 13. The work vehicle of claim 12, wherein an angular orientation with respect to the longitudinal axis of the first pin does not change between the hitched position and the unhitched position. 14. The work vehicle of claim 12, wherein in the hitched position, the first end of the first pin is secured substantially beneath a first surface of the upper portion of the member. 15. The work vehicle of claim 12, wherein in the unhitched position, the second end of the first pin is secured substantially above a second surface of the lower portion of the member. 16. The work vehicle of claim 12, wherein openings formed in the upper portion and the lower portion of the member include a slot to receive the second. 17. The work vehicle of claim 12, wherein upon installation of the third pin in the first pin, the third pin supports the first pin in the hitched position. 18. The work vehicle of claim 17, upon removal of the third pin from the first pin, the second pin supports the first pin in the unhitched position. 19. The work vehicle of claim 12, wherein the fourth pin limits movement of the first pin in the longitudinal direction, preventing removal of the first pin from the lower portion of the member. 20. The work vehicle of claim 12, wherein an opening formed in the member to receive the first pin is at least partially located beneath a hood of the work vehicle.
