摘要： An automatic feed system for a trimmer is provided. Such trimmers include a line that can be spun at high speeds to cut vegetation along roadsides or other areas. The automatic feed system is configured to dynamically detect the current length of the line and automatically feed the line to maintain a maximum or desired length for cutting. This length may typically correspond with the radius of a trimmer deck in which the line spins.

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.

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 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： Sod harvesters can have hydraulic systems that are configured to actuate components with precise timing. The hydraulic system of a sod harvester can be configured to maintain the temperature of hydraulic fluid both during harvesting and while harvesting is paused to thereby eliminate or minimize the occurrence of periods of variation in the timing of actuation of the components that the hydraulic fluid drives. As a result, these components can be consistently actuated with precise timing even after harvesting has been paused. Additionally, such configurations can minimize the amount of time required to warm the hydraulic fluid to a steady operational temperature.

摘要： A mower can be adaptively controlled to optimize efficiency based on loads experienced by motors that drive the cutting blades and/or based on vertical movement that a mower deck is experiencing. If the load is below a threshold, the ground speed of the mower can be increased. If the vertical movement or load exceeds a threshold, the ground speed can be reduced. 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. A density map can be created based on monitored load, vertical movement and possibly other characteristics as a mower is cutting a particular area. The density map can be employed by any mower that is subsequently used to cut the same area.

摘要： A stacking head's path can be dynamically calculated during a stacking operation. A control system of a sod harvester can include a dynamic path calculator for performing these dynamic calculations to prevent the stacking head from colliding with the sod harvester's frame or to cause the stacking head to traverse the most efficient path between the pickup position and the stacking position. These dynamic calculations could be performed in scenarios where the pickup position may be dynamically adjusted for a particular stacking operation.

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 sod harvester can employ a roll forming mechanism that includes a roll starter that is configured to initiate the formation of rolls. The roll starter can include pivoting supports and front and rear slab flippers that also pivot to cause the rolls to be tightly and consistently formed. The roll forming mechanism can also include a roll advancer that continues the formation of the rolls. The roll advancer can be suspended to cause it to conform to the shape and size of the rolls as they advance.
