Abstract
Abstract A tree harvester or remover is illustrated having a gripper including a V-shaped wedging member with a blade projecting inwardly thereof for cutting into a portion of the tree above the roots forming a shelf with adjacent fibers of the tree compressed between the wedging members, and means for exerting an upward force on the gripper by exerting a compressive force between ground engaging support members and an elevatable frame from which the gripper depends.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A tree pulling apparatus carried by a wheeled vehicle comprising: an elongated arm pivotally carried by the vehicle on one end thereof and extending forwardly and downwardly therefrom; first fluid power operated cylinder means connected to said elongated arm intermediate the ends thereof for raising and lowering same; a tiltable supporting frame having a lower inner end pivotally carried upon a free end of said elongated arm and a lower forward end supportable upon the ground; second fluid power operated cylinder means pivotally connected to said tiltable frame for imparting tilting movement thereto; an elevatable frame member having pivotal connection adjacent an upper rearward portion of said tiltable frame; tree gripping means carried by said elevatable frame extending forwardly thereof; and a pair of transversely aligned power operated cylinders, having pivotal mounting between a forward lower end of said tiltable frame and forward portion of said elevatable frame member, and being spaced on each side of said tree gripping means.
Claim 2
Dependent Claim
160 words
A tree pulling apparatus carried by a wheeled vehicle comprising: an elongated arm pivotally carried by the vehicle on one end thereof and extending forwardly and downwardly therefrom; first fluid power operated cylinder means connected to said elongated arm intermediate the ends thereof for raising and lowering same; a tiltable supporting frame having a lower inner end pivotally carried upon a free end of said elongated arm and a lower forward end supportable upon the ground; second fluid power operated cylinder means pivotally connected to said tiltable frame for imparting tilting movement thereto; an elevatable frame member having pivotal connection adjacent an upper rearward portion of said tiltable frame; tree gripping means carried by said elevatable frame extending forwardly thereof; and a pair of transversely aligned power operated cylinders, having pivotal mounting between a forward lower end of said tiltable frame and forward portion of said elevatable frame member, and being spaced on each side of said tree gripping means.
Claim 3
Dependent Claim
74 words
the structure set forth in claim 1 wherein said tree gripping means includes outwardly diverging tree engaging members, linkage means having pivoted connection adjacent said tree gripping means and said elevatable frame, and support means fixed to said gripping means having pivotal connection adjacent an upper rear portion of said tiltable frame; whereby said gripping means moves outwardly, upwardly to engage said tree and in an arc as said elevatable frame is pivotal upwardly.
Claim 4
Dependent Claim
28 words
The structure set forth in claim 1 or 2 including a trunk supporting member carried by a forward portion of the tree when said elevatable frame is raised.
Claim 5
Dependent Claim
22 words
The structure set forth in claim 3 wherein inwardly extending opposed blade members are integrally carried by said diverging tree engaging members.
Claim 6
Dependent Claim
28 words
The structure set forth in claim 3 including a pair of horizontal ground engaging shoes having pivotal intermediate support adjacent said lower forward end of said tiltable frame.
Claim 7
Dependent Claim
112 words
A tree pulling apparatus carried by a vehicle comprising: a supporting frame member carried adjacent a forward end of said vehicle; said frame having an upright member and a lower member extending forwardly from said upright member in fixed relation thereto; an elevatable frame member having a pivotal connection adjacent an upper portion of said upright member above said lower member extending forwardly therefrom; tree gripping means depending from a forward portion of said elevatable frame member; ground engaging means carried by a forward portion of said lower forwardly extending member; and power operated means exerting a force between said ground engaging means and a forward end of said elevatable frame member.
Claim 8
Dependent Claim
112 words
A tree pulling apparatus carried by a vehicle comprising: a supporting frame member carried adjacent a forward end of said vehicle; said frame having an upright member and a lower member extending forwardly from said upright member in fixed relation thereto; an elevatable frame member having a pivotal connection adjacent an upper portion of said upright member above said lower member extending forwardly therefrom; tree gripping means depending from a forward portion of said elevatable frame member; ground engaging means carried by a forward portion of said lower forwardly extending member; and power operated means exerting a force between said ground engaging means and a forward end of said elevatable frame member.
Claim 9
Dependent Claim
44 words
The structure set forth in claim 6 wherein said tree gripping means include diverging wedging members carrying opposed blade members extending inwardly thereof, and wherein said power operated means includes a pair of cylinders spaced transversely on each side of a tree being pulled.
Claim 10
Dependent Claim
25 words
The structure set forth in claim 7 including a holding mechanism carried by said elevatable frame for engaging the tree above said tree gripping means.
Claim 11
Dependent Claim
