    摘要: A sod harvester can include a preliminary stacking head for stacking slabs of sod prior to the stacked slabs being removed from a stacking conveyor for stacking on a pallet. In this way, the stacking head can remove multiple layers of sod during a single stacking operation. The preliminary stacking head can be positioned overtop a conveyor and can be configured to pick up a slab of sod as the slab travels along the conveyor. The preliminary stacking head can then drop the slab on top of a trailing slab thereby forming a stack of slabs on the conveyor. The conveyor over which the preliminary stacking head is positioned can be an inclined conveyor that transports slabs of sod from the ground to a stacking conveyor.

    摘要: A mower's control system can maintain horizon maps that associate horizon features with known relative positions. When a mower's orientation is unknown, the control system can obtain an image that captures the horizon from the mower's current viewpoint. The control system can process the image to detect any horizon features that appear within the image and to determine their positions within the image. The control system can then access a horizon map to identify matching horizon features. The control system can compare the known relative positions of any matching horizon features with the positions of the horizon features within the image to thereby determine the mower's current orientation.

    摘要: A mower deck can include roller assemblies that prolong the life of bearings by more evenly distributing the roller's load to the bearings. The roller assembly can include a roller that is secured between opposing bearings via a tapered shaft of the roller and a correspondingly tapered collar that is housed within the corresponding bearing. The interface between the tapered shaft and the tapered collar causes the collar to be secured snugly within the bearing while also providing even distribution of the roller's load to the bearing.

    摘要: A roll forming mechanism can include a passive roll-up mechanism that initiates the roll and an active roll-up mechanism that completes the roll. The active roll-up mechanism can include an upper conveyor that is rotated in different directions. The upper conveyor can initially be rotated in a direction opposite that of an inclined conveyor to cause a forming roll to advance along the inclined conveyor. The rotation of the upper conveyor can then be reversed to cause the roll to be completed. Then, the upper conveyor can again be rotated in the direction opposite that of the inclined conveyor to cause the completed roll to be transferred towards the stacking conveyor. The amount by which the upper conveyor is rotated in the reverse direction can be based on a detected length of a tail of the forming roll.

    摘要: A mower deck can include a linkage that enables adjusting the height of the mower deck with a single action. The mower deck can include a rolling mechanism support arm at each corner and a coupling mechanism that extends between the front and rear rolling mechanism support arms on each side of the mower deck. A shaft can extend between the two front rolling mechanism support arms and can be rotated via an actuator. When the shaft is rotated, the front rolling mechanism support arms will rotate in unison, and the coupling mechanisms will cause the rear rolling mechanism support arms to also rotate in unison. In this way, a single action can cause the height of the mower deck to be adjusted. Alternatively, a mower deck can include a height adjustment mechanism at each corner of the mower deck which can be controlled synchronously to adjust the height.
