First claim
Opening claim text (preview).
The invention claimed is: 1. A caster wheel assembly of a pickup for an agricultural machine, comprising: a wheel on a carrier shaft mounted rotatably within a bushing of a pickup arm, the wheel biased by a spring to be oriented in a predetermined direction relative to the pickup arm, wherein the spring is a helical spring positioned coaxially with the carrier shaft and attached at its one end to the carrier shaft and at its second end to the bushing. 2. The caster wheel assembly according to claim 1 , wherein the helical spring is positioned above the pickup arm. 3. The caster wheel assembly according to claim 1 , wherein the helical spring is positioned below the pickup arm. 4. The caster wheel assembly according to claim 1 , wherein the helical spring is positioned inside the carrier shaft. 5. The caster wheel assembly according to claim 1 , wherein the helical spring is positioned outside the carrier shaft. 6. The caster wheel assembly according to claim 5 , wherein the helical spring is protected by a cover. 7. The caster wheel assembly according to claim 1 , wherein the helical spring is positioned inside the bushing housing. 8. The caster wheel assembly according to claim 1 , wherein the helical spring is attached releasably. 9. The caster wheel assembly according to claim 1 , wherein the helical spring allows the wheel to rotate by at least 270 degrees to at least 360 degrees. 10. The caster wheel assembly according to claim 1 , wherein the point of contact between the wheel and the ground lies in line with the projection of the axis of the carrier shaft. 11. The caster wheel assembly according to claim 1 , wherein the point of contact between the wheel and the ground is offset from the point of the projection of the axis of the carrier shaft onto the ground.
