A wheel grid includes a crossbar configured to be coupled to a boom of a tow vehicle and including a distal tip. The wheel grid further includes an L-arm rotatably coupled to the crossbar at a proximal end of the L-arm and configured to rotate from an engaged position to a stowed position. As the L-arm rotates from the engaged position to the stowed position, a distal portion of the L-arm intersects with a vertical line passing through the respective left or right distal tip of the crossbar. In the stowed position, the distal portion of the L-arm is positioned laterally inward relative to the distal tip of the crossbar.
