Sod roll stacking technique

A method for stacking rolls of sod on a pallet, the method comprising:

• causing the sod harvester to form a first type of layer on the pallet, the first type of layer including a plurality of groups of rolls and a plurality of offset rolls, the sod harvester forming the first type of layer on the pallet by performing the following:
• for each of the plurality of offset rolls, causing a stacking head to pick up and stack the offset roll on the pallet in isolation;
• and
• causing the stacking head to pick up and stack each of the plurality of groups of rolls on the pallet, each group comprising an accumulated plurality of rolls;
• wherein the offset rolls are stacked in a center region of the pallet and each of the groups of rolls is stacked along a side of the pallet.

A method for forming a pallet of rolls of sod, the method comprising:

• forming alternating first and second types of layers on the pallet, each first type of layer including a plurality of first groups of rolls and a plurality of offset rolls, each second type of layer including a plurality of second groups of rolls;
• wherein each first type of layer is formed by:
• picking up and stacking each offset roll on the pallet in isolation;
• and
• picking up and stacking each of the plurality of first groups of rolls on the pallet, each first group of rolls including a first number of rolls, the offset rolls being stacked in between the plurality of first groups of rolls;
• and
• wherein each second type of layer is formed by:
• picking up and stacking each of the plurality of second groups of rolls on the pallet, each second group of rolls including a second number of rolls, the second number being less than the first number.
