Grain tank reinforcement for agricultural vehicle

A system for fastening a tension rod of a grain tank of an agricultural vehicle to a frame of the agricultural vehicle to which the grain tank is mounted, said system comprising:

• the tension rod having an elongated body extending between a first connection end that is configured to be connected either directly or indirectly to the grain tank, and a second connection end including openings for respectively receiving fasteners;
• a first member that is configured to be mounted to the frame, said first member including (i) openings for respectively receiving the fasteners and (ii) a first non-planar mounting surface;
• and
• a second member including (i) openings for respectively receiving the fasteners and (ii) a second non-planar mounting surface that is configured to be directly engaged with the first non-planar mounting surface to limit relative motion between the tension rod and the frame in an assembled state,
• wherein either (i) the openings of the first member are larger than the openings of the second connection end of the tension rod or (ii) the openings of the first member are larger than the openings of the second member.

A combine harvester comprising:

• a vehicle frame;
• a grain tank mounted to and supported by the vehicle frame;
• a tension rod positioned at least partially within an interior region of the grain tank and mounted to both the vehicle frame and the grain tank, the tension rod having an elongated body extending between a first connection end that is connected either directly or indirectly to the grain tank, and a second connection end including openings for respectively receiving fasteners;
• a first member that is mounted to the frame, said first member including (i) openings for respectively receiving the fasteners and (ii) a first non-planar mounting surface;
• a second member including (i) openings for respectively receiving the fasteners and (ii) a second non-planar mounting surface that is directly engaged with the first non-planar mounting surface to limit relative motion between the tension rod and the frame in an assembled state;
• and
• the fasteners, wherein each fastener mounts together the first member, the second member, the frame, the second connection end of the tension rod, and the grain tank.
