摘要： Sod harvester stacking head and stacking conveyor configurations can increase the rate at which sod can be harvested. The movement of the stacking head and/or the stacking conveyor can be controlled to maximize the rate at which the stacking head can remove sod from the stacking conveyor. A stacking head can employ multiple pick up positions. A stacking conveyor may also advance sod for pick up at varying rates. A stacking head may include a pivoting connection to allow the stacking head to rotate around a pivot during a pick up operation.

摘要： A mower can dynamically adjust the cutting height of a mower deck based on a mower's location. As a mower travels over an area of grass to be cut, a control system can track the current location of each mower deck on the mower. The control system can compare the current location of a mower deck to a boundary of one or more sections defined within the area to thereby determine which section the mower deck is within. When the control system detects that a mower deck has crossed or will cross into a section, it can identify a particular cutting height assigned to the section and dynamically adjust the cutting height of the mower deck to the particular cutting height. When a mower includes more than one mower deck, the control system can be configured to independently adjust the cutting height of each mower deck based on its location.

摘要： A sod harvester's stacking position can be dynamically adjusted to form vertically aligned stacks. More particularly, a sod harvester's control system can be configured to automatically adjust the stacking position as a stack is being formed based on a sensed orientation of the pallet. In this way, the control system can ensure that a slab of sod that is dropped from the stacking head will fall into the intended location on the stack regardless of the orientation of the pallet relative to the stacking head.

摘要： A stacking head for stacking rolls of sod can include a number of screw assemblies that are employed to secure and remove sod rolls from a stacking conveyor. Each screw assembly can include a center stake and a corkscrew that pierce a roll as the stacking head is forced into the roll. The rate at which the stacking head is moved vertically relative to the roll can be synchronized with the rate at which each screw assembly is rotated. This synchronization ensures that the corkscrew will pass into the roll while the stacking head is simultaneously forced into the roll without damaging the delicate sod.

摘要： A cutting head for a sod harvester is configured to counterbalance forces that are generated during operation. When the cutting head is operated, the cutting blade oscillates to sever sod from the ground. This oscillation of the cutting blade generates significant horizontal vibration forces that are transferred to the cutting head and other components of the sod harvester. The cutting head can include a crankshaft assembly with counterweights that are designed to balance these horizontal vibration forces. The cutting head can also include a countershaft assembly with counterweights that are also designed to balance these horizontal vibration forces while also balancing vertical vibration forces that the counterweights of the crankshaft assembly create.

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 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 sod harvester stacking head can include a base that couples to a stacking head supporting mechanism of a sod harvester and a frame that couples to the base via crankshaft assemblies that are configured to allow the frame to rotate through 360 degrees during each stacking operation. Accordingly, a motor that controls the rotation of the crankshaft assemblies can be driven a single time during each stacking operation thereby enhancing the efficiency of the sod harvester. The crankshaft assemblies can also be configured so that the crankshafts are in a vertical orientation while the stacking head travels in a lateral direction such that the load is centered on the rotational axis of the stacking head. A stacking conveyor could similarly be configured with a base and a frame that are coupled via crankshaft assemblies to thereby allow the stacking conveyor to be lifted using 360 degrees of rotation.

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.
