Claim 1

Independent Claim 189 words

A soil treating machine comprising: A. A frame member B. A wheel rotatably mounted on said frame member for rotation in a first direction; C.

Claim 4

Dependent Claim 63 words

Spring meaNs supported by said wheel for resiliently maintaining said tubes in engagement with said limit means; whereby the position of the tubular axis of each said tube is variable with a fixed limit provided by said limit means, and voids in earth are obtained which are equally spaced and have a minimum taper as said wheel is rotated in said first direction.

Claim 5

Dependent Claim 11 words

substantially perpendicular to the tubular axis of each said tube, and

Claim 6

Dependent Claim 11 words

substantially perpendicular to the tubular axis of each said tube, and

Claim 7

Dependent Claim 63 words

Spring meaNs supported by said wheel for resiliently maintaining said tubes in engagement with said limit means; whereby the position of the tubular axis of each said tube is variable with a fixed limit provided by said limit means, and voids in earth are obtained which are equally spaced and have a minimum taper as said wheel is rotated in said first direction.

Claim 8

Dependent Claim 63 words

Spring meaNs supported by said wheel for resiliently maintaining said tubes in engagement with said limit means; whereby the position of the tubular axis of each said tube is variable with a fixed limit provided by said limit means, and voids in earth are obtained which are equally spaced and have a minimum taper as said wheel is rotated in said first direction.

Claim 9

Dependent Claim 51 words

The soil treating machine set forth in claim 1 further comprising soil holding means supported by said wheel for yieldably engaging soil around a substantial portion of the periphery of each said tube and holding peripheral soil in place as a said tube removes a core of soil from the ground.

Claim 10

Dependent Claim 92 words

The soil treating machine as set forth in claim 1 further comprising: A. Sod planting means for receiving plugs of sod of the same configuration as said cores of soil and injecting said plugs of sod into voids created by the removal of said cores of soil; and B. coupling means operatively connected to said first wheel and said sod planting means for controlling the position of injection of said plugs of sod in register with the said voids created by the removal of said cores of soil by said coring tubes.

Claim 11

Dependent Claim 28 words

offset from said tubular axis in a direction corresponding to said first direction of rotation of said wheel, and E. Tube positioning means supported by said wheel comprising:

Claim 12

Dependent Claim 28 words

offset from said tubular axis in a direction corresponding to said first direction of rotation of said wheel, and E. Tube positioning means supported by said wheel comprising:

Claim 13

Dependent Claim 119 words

A soil treating machine as set forth in claim 3 wherein said sod planting means comprises: A. A second wheel rotatably mounted on said frame; B. Sod holding receptacles of like circumferential spacing as said tubes on said first wheel and being positioned about the periphery of said second wheel and including sod ejection means for applying an ejection force to sod held in said holding receptacles; and C. Guide means generally concentric with and outwardly spaced from said second wheel for maintaining sod in said receptacles until a sod filled receptacle reaches a position over a said void in the soil permitting a said plug of sod to be ejected from a said receptacle into a said void.

Claim 14

Dependent Claim 52 words

A soil treating machine as set forth in claim 4 wherein said sod holding receptacles coacting with said guide means comprise sod receiving means for individually receiving a plurality of said plugs of sod in a continuous flow and positioning each said plug in a said receptacle as said second wheel turns.

Claim 15

Dependent Claim 58 words

The soil treating machine set forth in claim 5 further comprising plug depressing means including a third wheel mounted on said frame member and separated from said first wheel by said second wheel and being of a width and position to depress said plugs of sod as said soil treating machine is moved in a forward operating direction.

Claim 16

Dependent Claim 120 words

The soil treating machine set forth in claim 10 wherein said plug depressing means comprises: A. Coupling means operatively connecting said second wheel and said third wheel for maintaining register between said second wheel and third wheel whereby the position of depression applied by said depression means is accurately maintained; and B. A plurality of crimping frames, each generally corresponding to the configuration of a said plug of sod and mounted on the periphery of said third wheel; and C. The diameter of said third wheel and the number and position of said crimping frames being arranged to apply a compression of soil around the edges of each planted core of sod as said machine traverses the area being treated.
