System for supporting an unload tube of an agricultural vehicle

An agricultural vehicle grain tank assembly, the agricultural vehicle grain tank assembly comprising:

• a grain tank:
• an unload tube moveably mounted to the grain tank between a deployed position and a stowed position:
• a tension rod having an elongated body extending between a first end that is connected to the grain tank and a second end arranged opposite the first end and having a first non-planar mounting surface;
• and
• a support member including a first end that is connected to the unload tube and a second end that is directly connected to the second end of the tension rod, the second end of the support member being arranged opposite the first end of the support member and having a second non-planar mounting surface that is directly engaged with the first non-planar mounting surface to prevent relative motion between the tension rod and the unload tube in an assembled state of the system,
• wherein the tension rod and the support member are fixed to each other and the grain tank such that the unload tube moves between the deployed position and the stowed position relative to the tension rod and the support member.
