Abstract

Abstract Sod is removed from the field in standard width strips and the strips are cut into equal length sections. Excess moisture, when present, is removed from the sod prior to delivering the sod sections to an apparatus which removes excess soil from the bottom of the sod to reduce weight and form a product of uniform thickness. The sod sections are then delivered soil side up to a scoring and trimming apparatus which trims each section to an accurate length and scores the sod partly through the root structure longitudinally and transversely to form a plurality of equally-sized rectangular plugs in each sod section which can be easily separated by a user. Prior to the second scoring operation, pairs of sod sections are placed on moisture-absorbing trays and following the second scoring, plural layers of processed sod sections and intervening trays are placed in superposed relation in a shipping carton having a moisture-impermeable liner. Moisture held in the absorbent trays is gradually given back to the living sod during shipment.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 77 words
A method of treating sod prior to usage thereof by a consumer comprising forming approximately rectangular sections of harvested sod, removing excess moisture from the harvested sod, removing excess soil from the sod sections following the removal of excess moisture to reduce the weight and bulk of the sod sections, and scoring the sod sections on the soil sides thereof in two directions to form on each sod section a multiplicity of attached readily separable sod plugs.
Claim 2
Independent Claim 77 words
A method of treating sod prior to usage thereof by a consumer comprising forming approximately rectangular sections of harvested sod, removing excess moisture from the harvested sod, removing excess soil from the sod sections following the removal of excess moisture to reduce the weight and bulk of the sod sections, and scoring the sod sections on the soil sides thereof in two directions to form on each sod section a multiplicity of attached readily separable sod plugs.
Claim 3
Independent Claim 111 words
A method of preparing sod for planting by a consumer in plug form in a remote location comprising harvesting sod strips from a growing field, severing the harvested strips into sections of substantially uniform size, removing excess moisture from the sod when present therein prior to the removal of soil, removing excess soil from the sod sections to lessen their weight and bulk while imparting substantially uniform thickness to them, scoring the sod sections partly through their thicknesses in two coordinate directions to form on each section a multiplicity of relatively small readily separable attached sod plugs, and packaging a plurality of the scored sod sections for shipment to distant consumers.
Claim 4
Independent Claim 111 words
A method of preparing sod for planting by a consumer in plug form in a remote location comprising harvesting sod strips from a growing field, severing the harvested strips into sections of substantially uniform size, removing excess moisture from the sod when present therein prior to the removal of soil, removing excess soil from the sod sections to lessen their weight and bulk while imparting substantially uniform thickness to them, scoring the sod sections partly through their thicknesses in two coordinate directions to form on each section a multiplicity of relatively small readily separable attached sod plugs, and packaging a plurality of the scored sod sections for shipment to distant consumers.
Claim 5
Dependent Claim 25 words
The method of claim 2, and the additional step of trimming the sod sections during said scoring at least on one pair of side edges.
Claim 6
Dependent Claim 22 words
The method of claim 2, and the additional step of placing the sod sections on moisture-absorbing tray elements prior to said packaging.
