  • Patent number: 6273196
    Abstract: A sod cutting apparatus includes a cutting head positioned to cut grass sods from grass land and a sod receiving conveyor positioned adjacent the cutting head for receiving the cut grass sods from the cutting head. The sod receiving conveyor has a discharge end which extends away from the cutting head and which is moveable between a first position and a second position. An intermediate conveyor is positioned adjacent the discharge end of the sod receiving conveyor for receiving a first cut grass sod from the discharge end of the sod receiving conveyor in the first position. An offset conveyor is positioned in spaced relation to the intermediate conveyor adjacent the discharge end of the sod receiving conveyor for receiving a second cut grass sod from the sod receiving conveyor in the second position. The intermediate conveyor and the offset conveyor are operable so that the offset conveyor stacks the second cut grass sod on the first cut grass sod.

  • Patent number: 6244354
    Abstract: A method and apparatus for cutting a grass sod from a grass land are disclosed. The apparatus includes a cutting blade positioned between a front end and rear end of a sod cutting apparatus. An adjusting mechanism adjusts the position of the cutting blade to cut the grass sod a predetermined distance below a surface of the grass sod. A measuring mechanism measures a profile of the grass sod to be cut from the grass land and/or a thickness of the cut grass sod. A controller is connected to the measuring mechanism and the adjusting mechanism. The controller causes the adjusting mechanism to adjust the position of the cutting blade in response to the measuring mechanism detecting changes in the profile of the grass sod to be cut from the grass land and/or the thickness of the cut grass sod. The method includes setting a cutting blade to cut from the grass land the grass sod having the predetermined thickness.
