A grain cart comprising:
- a frame;
- ground wheels for supporting the frame;
- a hitch assembly connected to a front end of the frame;
- a storage hopper supported on the frame and defining an interior space, the storage hopper having an upper wall;
- and, a lower wall extending downwards from the upper wall, the upper wall extending substantially vertically and the lower wall angled inwards as the lower wall extends down from the upper wall;
- an opening passing through the lower wall;
- an access door sized to cover the opening and opening into the interior space;
- and
- a ladder assembly directly and pivotally attached at a top end of the ladder to the inwardly angled lower wall by a pivotal connection below the opening, the ladder assembly comprising:
- an upper ladder portion having:
- a top end corresponding to the top end of the ladder;
- and, a bottom end;
- and
- a lower ladder portion having:
- a top end;
- and, a bottom end, the top end pivotally connected at a lower connection point to the bottom end of the upper ladder portion,
- wherein the ladder assembly is unfoldable into an extended position to provide access to the opening and the access door by pivoting the lower ladder portion around the lower connection point and away from the upper ladder portion,
- and wherein the ladder assembly is foldable into a retracted position by pivoting the lower ladder portion around the lower connection point and towards the upper ladder portion, and pivoting the ladder assembly around the pivotal connection, towards the lower wall below the pivotal connection, until the ladder position is positioned adjacent to the lower wall below the opening.
