ABSTRACT:

FIELD OF THE INVENTION
This invention relates generally to sod harvesting equipment and more specifically to an on-the-go sod harvester that automatically cuts, rolls and stacks sod for machine pickup of the stacked sod.
BACKGROUND OF THE INVENTION
The concept of sod harvesting is old in the art. Typically, a sod slab is cut free from a sod field. The slab is then rolled up into a cylindrical roll that is transferred to a pallet or a sod pickup mechanism. If the sod rolls are “small rolls”, the sod rolls can be manually transferred to a sod delivery truck that delivers the sod to the area where the sod rolls are to be laid. If the sod rolls are “big rolls”, it is necessary to use equipment to both lift and transfer the sod rolls. Numerous devices are available for mechanizing portions of the sod harvesting and delivering process. For example, U.S. Pat. No. 5,230,602 shows a sod roll stacker for stacking rows of small rolls. Still other devices are available for cutting and rolling both small rolls and big rolls. The present invention comprises an apparatus and method that is suitable for automatic on-the-go cutting, rolling and stacking of small rolls of sod in a ready to transport condition.
SUMMARY OF THE INVENTION
Briefly, the present invention comprises a method of on-the-go cutting, rolling and stacking sod and an on-the-go sod harvester for automatically cutting, rolling and storing sod with the sod harvester including a sod cutter for freeing a section of sod from a sod field, a sod roller for rolling the section of sod into a sod roll, a sod roll accumulator having a set of sod troughs therein for receiving and holding the sod roll therein and a sod roll pickup mechanism for lifting the sod roll on the sod roll accumulator and stacking the sod roll on a sod carrier for later pick-up.
