| 摘要 | A land roller implement includes a wheel aligned with the respective gap between the inner roller and the outer roller of each wing in which the wheel is pivotal between a packing position in the working position of the rollers and a transport position supporting the rollers in the transport position of the implement. The wings can also include a drive motor associated with each transport wheel to drive forward rotation of the wheel for displacing the wings from the transport position to the working position without displacing the implement in a rearward direction. A levelling beam attachment and a seeding attachment can also optionally be used on the land roller implement. Optional latchable brace members pivotally supported on the wings may provide additional support to the wings when using the levelling beam attachment. | ||||||
