Sod handling apparatus
A method of stacking sod rolls can include: (a) moving a head of a sod handling apparatus to a sod pick-up location containing a plurality of sod rolls; (b) picking up a first sod roll with a first sod carrier, picking up a second sod roll with a second sod carrier, and picking up a third sod roll with a third sod carrier; (c) moving the head to a sod drop-off location; (d) depositing the first sod roll from the first sod carrier at the sod drop-off location; (e) after depositing the first sod roll, moving the second sod carrier and the third sod carrier toward the first sod carrier to reduce the spacing between the second and third sod rolls; and (f) depositing the second and third sod rolls at the drop-off location.
Sod scrap collection apparatus and method
A sod scrap collection apparatus is disclosed that enables pickup and collection of scraps of sod that have been discarded on the ground. The apparatus is pulled by a tractor and includes a pickup head followed by a dump bed. A pickup head conveyor moves pickup teeth along and over the ground at a particular distance in order to scrape up sod scraps and discard them into the dump bed where they are collected. A dump bed conveyor of the dump bed, which runs in the opposite direction as the pickup head conveyor, moves parallel spaced sweeping bars along a top of the sod scraps residing in the dump bed at an upward angle from front to back, so that the dump bed fills with the sod scraps efficiently from front to back.
SOD HARVESTER HYDRAULIC SYSTEM FOR ACTUATING COMPONENTS WITH PRECISE TIMING
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.
Removing sod from a stacking conveyor
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.

Sod harvester having auxiliary stacking conveyor
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.

SOD HANDLING APPARATUS
A method of stacking sod rolls on a pallet includes operating a sod handling apparatus of a sod harvester to form a plurality of layers of the sod rolls on the pallet. Each layer contains nine sod rolls comprising a row of five sod rolls positioned next to each other, a first pair of sod rolls oriented perpendicular to the five sod rolls of the row and positioned adjacent an inner end of the row, and a second pair of sod rolls oriented perpendicular to the five sod rolls of the row and positioned adjacent the inner end of the row parallel and in alignment with the first pair of sod rolls. The plurality of layers are flipped relative to each other in an alternating manner to position the row of five sod rolls of each upper layer atop the first and second pairs of sod rolls of a respective lower layer parallel with the row of five sod rolls of the lower layer, and the first and second pairs of sod rolls of the upper layer atop the row of five sod rolls of the lower layer parallel with the first and second pairs of sod rolls of the lower layer.
