摘要： Sod harvesters are configured to stack rolls of sod in layers on a rectangular pallet. A sod harvester can include control circuitry that is configured to operate a stacking head and a stacking conveyor in a manner that produces a first type of layer that includes spaced groups of accumulated rolls and a number of offset rolls positioned between the groups. The stacking head can pick up and stack each offset roll in isolation and may pick up the offset rolls in a center position of the stacking head.

摘要： A mower can be adaptively controlled to optimize efficiency based on loads experienced by motors that drive the cutting blades. If the load is below a threshold, the ground speed of the mower can be increased. The mower's performance can also be monitored to identify characteristics of an area being cut and then such characteristics can be used to further enhance the efficiency of the mower.

摘要： A sod harvester can include an auxiliary stacking conveyor for stacking or folding slabs of sod on an inclined conveyor prior to the stacked/folded slabs being removed from a stacking conveyor by a stacking head. The auxiliary stacking conveyor can be configured to receive a leading slab of sod and then stack the leading slab on top of a trailing slab while the trailing slab is being advanced along an inclined conveyor. The auxiliary stacking conveyor can also be configured to partially receive a slab of sod and then reverse direction to cause the slab to be folded backwards on top of itself while being advanced along an inclined conveyor. Different configurations can be employed to cause slabs to be selectively positioned on an auxiliary stacking conveyor.

摘要： A steering system for a mower can include a wheel-specific driving unit for each wheel and a controller for providing control signals to each wheel-specific driving unit to thereby cause each wheel to be independently rotated at a different speed during a turn. By independently rotating each wheel, the mower can complete a turn without damaging the grass. The controller may also provide control signals to cause each steerable wheel to be positioned in a different wheel direction during the turn.

摘要： Low profile object detection can be performed on mowers or other vehicles that may be autonomous. An autonomy controller can be employed on a mower to receive and process sensor data for a detection area to determine whether an object may be present in a region of interest within the detection area. When the autonomy controller determines that an object may be present, it can cause the ground speed of the mower to be slowed and can commence buffering region of interest sensor data over a period of time. The autonomy controller can process the buffered region of interest sensor data to determine whether an object is present in the region of interest, and if so, can alter the path of the mower appropriately.

摘要： Synchronizing variables can be tuned based on a sod harvester's speed. A sod harvester's control system can include a tuning component that receives as input a current speed of the sod harvester. The tuning component can apply logic to the current speed to calculate values for synchronizing variables that are tuned for the current speed. In this way, the sod harvester can be operated with precision across a range of speeds, including at high speeds.

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 can include a control system that is configured to detect when the mower is turning or will be turned and can adaptively support one or more mower decks during the turn to transfer weight from the mower decks to the mower's tires. This transfer of weight will increase the traction of the mower's tires while also minimizing the yawing force caused by the mower decks thereby preventing the mower from slipping during the turn.

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.
