3. The agricultural vehicle of claim 1 , wherein the composite tube has an exterior surface, wherein the ferrule has an interior surface, and wherein the interior surface of the ferrule is contiguous with the exterior surface of the composite tube.

4. The agricultural vehicle of claim 1 , wherein the composite tube is a carbon fiber tube.

5. An agricultural vehicle comprising:

a chassis;

wheels supporting the chassis for moving the vehicle;

an application system supported by the chassis and including a product tank storing a volume of agricultural product for delivery onto an agricultural field;

an application boom configured to deliver the agricultural product to the agricultural field, the application boom including:

a boom center section; and

a first boom arm supported by the boom center section, the first boom arm including;

a longitudinal composite tube with an end;

a non-composite member coupled with the longitudinal composite tube at the end of the longitudinal composite tube; and

a ferrule fastening the non-composite member to the longitudinal composite tube, the ferrule being disposed at the end of the longitudinal composite tube,

wherein:

the non-composite member further includes a ridge being contiguous with the end of the longitudinal composite tube;

the ridge extends beyond an exterior surface of the longitudinal composite tube; and

the ferrule includes a groove to receive a portion of the ridge of the non-composite member.

6. The agricultural vehicle of claim 5 , wherein the longitudinal composite tube is a carbon fiber tube.

7. The agricultural vehicle of claim 5 , wherein the non-composite member is a cast metallic member.

8. The agricultural vehicle of claim 7 , wherein the cast metallic member couples the first boom arm and to the boom center section.

9. The agricultural vehicle of claim 5 , wherein the longitudinal composite tube has an inner cross section and an exterior surface, wherein the non-composite member includes an exterior cross section being contiguous with the inner cross section of the longitudinal composite tube.

10. The agricultural vehicle of claim 9 , wherein the exterior surface is an elliptical or oval shape, and wherein the inner cross section is an elliptical or oval shape.

11. The agricultural vehicle of claim 5 , wherein the ferrule includes a metallic ferrule having multiple pieces.

12. The agricultural vehicle of claim 5 , wherein the ferrule surrounds the end of the longitudinal composite tube.

13. The agricultural vehicle of claim 5 , and further comprising a lift arm arrangement that connects the boom center section to the chassis and that is configured to raise and lower the boom.

14. An agricultural vehicle comprising:

a chassis;

wheels supporting the chassis for moving the agricultural vehicle;

an application system supported by the chassis and including a product tank storing a volume of agricultural product for delivery onto an agricultural field;

an application boom configured to deliver the agricultural product to the agricultural field, the application boom including;

a boom center section;

a first boom arm and a second boom arm, both of which being supported by the boom center section, each of the first boom arm and second boom arm including, respectively;

a truss system having a longitudinal carbon fiber tube with an end, the longitudinal carbon fiber tube having an inner cross section and an exterior surface, the inner cross section being an elliptical or oval shape;

a cast metal member coupled with the longitudinal carbon fiber tube, the cast metal member including an exterior cross section being contiguous with the inner cross section of the longitudinal carbon fiber tube, the cast metal member further including a ridge extending beyond the exterior surface of the longitudinal carbon fiber tube and being contiguous with the end of the longitudinal carbon fiber tubed; and

a metallic ferrule fastening the cast metal member to the longitudinal carbon fiber tube, the metallic ferrule being disposed at the end of the longitudinal composite tube and surrounding the end of the longitudinal carbon fiber tube, the metallic ferrule including a groove to receive a portion of the ridge of the cast metal member; and

a lift arm arrangement connecting the application boom to the chassis and that is configured to raise and lower the application boom.
