A tow bar for selectively securing a pivotable container assembly of a dump cart includes a tow bar rotatably connected to a frame of the container assembly. A latch is adjacent to a receiving surface of the tow bar, and includes a slidable member, a biasing element and a lever. The slidable member is configured to selectively engage an arm which extends from the container assembly and for latching the container assembly in a loading condition. The biasing element is configured to urge the slidable member into engagement with the arm. The lever is coupled to the tow bar, slidably coupled to the slidable member and includes an actuation plate spaced apart from the receiving surface. When actuated, the lever moves the actuation plate toward the receiving surface and urges the slidable member away from the arm, enabling release of the engaged arm from the tow bar.

1. A tow bar assembly for selectively securing a container assembly of a dump cart in a loading condition, comprising: a tow bar rotatably connected to a frame of the dump cart, the tow bar having a receiving surface generally parallel to a longitudinal axis of the tow bar;a latch adjacent to the receiving surface, the latch comprising:a slidable member configured to selectively engage a distal portion of an arm, the arm extending from the container assembly and configured for latching the container assembly in the loading condition;a biasing element configured to urge the slidable member into engagement with the distal portion to secure the container assembly; anda lever coupled to the tow bar and slidably coupled to the slidable member, the lever including an actuation plate spaced apart from the receiving surface of the tow bar;wherein the lever, when actuated, moves the actuation plate toward the receiving surface and urges the slidable member away from the distal portion, enabling release of the engaged arm from the tow bar;the container assembly being pivotable into an unloading condition on at least one axis with respect to the longitudinal axis of the tow bar upon release of the arm. 2. The tow bar assembly of claim 1, wherein at least a portion of the slidable member is located within the tow bar. 3. The tow bar assembly of claim 1, wherein the latch further includes an actuator pin connected to the slidable member and slidably coupled to the lever, the actuator pin configured to allow the slidable member to slide toward a first end of the tow bar when the actuation plate is released, and toward a second end of the tow bar when the actuation plate is actuated. 4. The tow bar assembly of claim 3, wherein the lever includes a pair of spaced-apart flanges extending generally perpendicular to the actuation plate and located adjacent to opposing sides of the tow bar. 5. The tow bar assembly of claim 4, wherein the flanges each include an actuator groove configured to receive the actuator pin, the actuator grooves being configured to cause slidable movement of the actuator pin during actuation and release of the actuation plate. 6. The tow bar assembly of claim 5, wherein the tow bar includes a pair of spaced-apart first guide grooves configured to receive the actuator pin, the first guide grooves being configured to allow the slidable member to slide during actuation and release of the actuation plate. 7. The tow bar assembly of claim 6, wherein the slidable member is slidably connected to the tow bar by a guide pin, the guide pin being configured to allow the slidable member to slide during actuation and release of the actuation plate. 8. The tow bar assembly of claim 7, wherein the slidable member includes at least one second guide groove configured to receive the guide pin, the second guide groove being configured to allow the slidable member to slide during actuation and release of the actuation plate. 9. The tow bar assembly of claim 8, wherein the slidable member slides generally parallel to the longitudinal axis of the tow bar as the actuation plate is moved toward and away from the receiving surface. 10. The tow bar assembly of claim 1, wherein the latch includes a plurality of spaced-apart biasing elements, which include said biasing element, located on opposing sides of the slidable member. 11. The tow bar assembly of claim 1, wherein the distal portion of the arm includes a notched portion. 12. The tow bar assembly of claim 11, wherein the slidable member further includes a protrusion, the protrusion being configured for selective engagement of the notched portion. 13. The tow bar assembly of claim 12, wherein the notched portion extends into the tow bar when the container assembly is secured thereto. 14. The tow bar assembly of claim 1, wherein the lever is pivotably coupled to the tow bar at a proximal end, and is biased by the biasing element such that the actuation plate forms a predetermined angle greater than zero from the proximal end to a distal end with respect to the receiving surface of the tow bar when the container assembly is in the loading condition. 15. The tow bar assembly of claim 14, wherein predetermined angle is decreased toward zero as the actuation plate is urged toward the receiving surface. 16. The tow bar assembly of claim 14, wherein the distal end of the lever, when the lever is actuated to enable unloading of the container assembly, rotates toward a first end of the tow bar. 17. The tow bar assembly of claim 1, further comprising a connector configured to attach a first end of the tow bar to the frame, the connector configured to allow the container assembly to pivot on at least one axis with respect to the longitudinal axis of the tow bar when the arm is released from the tow bar. 18. The tow bar assembly of claim 1, further comprising a hitch attached to a second end of the tow bar. 19. A tow bar assembly for selectively securing a container assembly of a dump cart in a loading condition, comprising: a tow bar rotatably connected at a first end to a frame of the dump cart, the tow bar having a receiving surface generally parallel to a longitudinal axis of the tow bar;a latch adjacent to the receiving surface, the latch comprising:a slidable member configured to selectively engage a distal portion of an arm, the arm extending from the container assembly and configured for latching the container assembly in a loading condition;a biasing element configured to urge the slidable member into engagement with the distal portion to secure the container assembly; anda lever pivotably coupled to the tow bar and slidably coupled to the slidable member, the lever including an actuation plate urged by the biasing element to be spaced apart at an angle greater than zero from the receiving surface of the tow bar;wherein the lever, when actuated, moves the actuation plate toward the receiving surface and urges the slidable member away from the distal portion, enabling release of the engaged arm from the tow bar;the container assembly being pivotable into an unloading condition on at least one axis with respect to the longitudinal axis of the tow bar upon release of the arm.
