A farm implement includes a ladder for climbing in relation to a container. The ladder includes an upper ladder portion and a lower ladder portion. The upper end of the upper ladder portion is pivotably connected to the container via a first pivot defining a first horizontal pivot axis about which the upper ladder portion is pivotable between a retracted position against the container and an extended position angled away from the container, and a first end of the lower ladder portion is pivotably connected to the lower end of the upper ladder portion via a second pivot defining a second horizontal pivot axis about which the lower ladder portion is pivotable between a folded position extending upwardly along the upper ladder portion and an unfolded position extending downwardly from the upper ladder portion. A movable pivot link is pivotably connected to the lower end of the upper ladder portion via a third pivot defining a third horizontal pivot axis, and the upper ladder portion includes a pivoting step connected to the movable pivot link via the third pivot and connected to the upper ladder via a fourth pivot defining a fourth horizontal pivot axis about which the pivoting step is pivotable between retracted and extended positions.
