Abstract

According to an aspect of the present disclosure, a disk saw felling head has a fore-aft dimension, a lateral dimension, and a vertical dimension such that the fore-aft dimension, the lateral dimension, and the vertical dimension are perpendicular to one another. The disk saw felling head comprises a frame comprising a first mounting post, a second mounting post, a motor housing, and a horn section, The first and second mounting posts are configured for attaching the disk saw felling head to a base machine and spaced laterally apart from one another relative to the lateral dimension and extending vertically relative to the vertical dimension. The horn section is mounted to a top portion of the first mounting post and a top portion of the second mounting post relative to the vertical dimension.

First claim

What is claimed is:

1. A disk saw felling head, the disk saw felling head having a fore-aft dimension, a lateral dimension, and a vertical dimension such that the fore-aft dimension, the lateral dimension, and the vertical dimension are perpendicular to one another, the disk saw felling head comprising
a frame comprising a first mounting post, a second mounting post, a motor housing, and a horn section, the first and second mounting posts configured for attaching the disk saw felling head to a base machine and spaced laterally apart from one another relative to the lateral dimension and extending vertically relative to the vertical dimension, the horn section mounted to a top portion of the first mounting post and a top portion of the second mounting post relative to the vertical dimension, a disk saw,
a motor attached to the frame and the disk saw to rotate the disk saw relative to the frame, the motor positioned within the motor housing,
a harvesting arm attached pivotally to the frame to pivot relative thereto to gather a felled tree,
a harvesting cylinder attached to the frame and the harvesting arm to pivot the harvesting arm relative to the frame,
a bunching arm attached pivotally to the frame to pivot relative thereto to hold the felled tree against the horn section, and
a bunching cylinder attached to the frame and the bunching arm to pivot the bunching man relative to the frame, the harvesting cylinder or the bunching cylinder positioned above the motor housing relative to the vertical dimension,
a hydraulic line routed through an interior region of the first mounting post into an interior region of the horn section and out of the interior region of the horn section to the harvesting or bunching cylinder, and
wherein the horn section comprises a housing and a horn, the housing is mounted to the top portion of the first mounting post and the top portion of the second mounting post relative to the vertical dimension, and the horn is mounted atop the housing relative to tile vertical dimension, and the housing comprises the interior region of the horn section through which the hydraulic line is routed, and
wherein the first mounting post and the housing cooperate to provide a first aperture between the interior region of the first mounting post and the interior region of the housing, the housing comprises an external wall at a bottom of the housing relative to the vertical dimension, the external wall comprises a second aperture positioned between the first and second mounting posts, and the hydraulic line is routed from the first aperture into the interior region of the housing, through the interior region of the housing, and out of the second aperture to the harvesting or bunching cylinder.

2. The disk saw felling head of claim 1 , wherein the first mounting post and the housing cooperate to provide a first aperture between the interior region of the first mounting post and the interior region of the housing, the housing comprises an external wall at a bottom of the housing relative to the vertical dimension, the external wall comprises a second aperture positioned laterally between the first and second mounting posts relative to the lateral dimension, and the hydraulic line is routed through the first and second apertures.

3. The disk saw felling head of claim 2 , wherein a normal to the first aperture is vertical relative to the vertical dimension, a normal to the second aperture is vertical relative to the vertical dimension, and the housing comprises a bulkhead through which the hydraulic line extends horizontally relative to the vertical dimension.

4. The disk saw felling head of claim 1 , wherein the horn section comprises an external wall, the external wall comprises an aperture positioned laterally between the first and second mounting posts relative to the lateral dimension and through which the hydraulic line is routed out of the horn section.

5. The disk saw felling wherein the horn section comprises a bulkhead through which the hydraulic line is routed.

6. A disk saw felling head, the disk saw felling head having a fore-aft dimension, a lateral dimension, and a vertical dimension such that the fore-aft dimension, the lateral dimension, and the vertical dimension are perpendicular to one another, the disk saw felling head comprising
a frame comprising a first mounting post, a second mounting post, a motor housing, and a horn section, the first and second mounting posts configured for attaching the disk saw felling head to a base machine and spaced laterally apart from one another relative to the lateral dimension and extending vertically relative to the vertical dimension, the horn section mounted to a top portion of the first mounting post and a top portion of the second mounting post relative to the vertical dimension,
a disk saw,
a motor attached to the frame and the disk saw to rotate the disk saw relative to the frame, the motor positioned within the motor housing,
a harvesting arm attached pivotally to the frame to pivot relative thereto to gather a felled tree,
a harvesting cylinder attached to the frame and the harvesting arm to pivot the harvesting arm relative to the frame,
a bunching arm attached pivotally to the frame to pivot relative thereto to hold the felled tree against the horn section, and
a bunching cylinder attached to the frame and the bunching arm to pivot the bunching arm relative to the frame, the harvesting cylinder or the bunching cylinder positioned above the motor housing relative to the vertical dimension,
a hydraulic line routed through an interior region of the first mounting post and an interior region of the horn section to the harvesting or bunching cylinder, wherein both the harvesting cylinder and the bunching cylinder are positioned above the motor housing relative to the vertical dimension, the hydraulic line is a first hydraulic line, the first hydraulic line is routed through the interior region of the first mounting post and the interior region of the horn section to the harvesting cylinder, further comprising a second hydraulic line routed through an interior region of the second mounting post and the interior region of the horn section to the bunching cylinder.

7. The disk saw felling head of claim 6 , wherein the horn section comprises a housing and a horn, the housing is mounted atop the first mounting post and the second mounting post relative to the vertical dimension, and the horn is mounted atop the housing relative to the vertical dimension, the housing comprises the interior region of the horn section through which the first hydraulic line and the second hydraulic line is routed.

8. The disk saw felling head of claim 7 , wherein the first mounting post and the housing cooperate to provide a first aperture between the interior region of the first mounting post and the interior region of the housing, the second mounting post and the housing cooperate to provide a second aperture between the interior region of the second mounting post and the interior region of the housing, the housing comprises a third aperture and a fourth aperture, the third aperture and the fourth aperture are positioned laterally between the first and second mounting posts relative to the lateral dimension and are positioned at an exterior of the horn section, the first hydraulic line is routed through the first and third apertures, and the second hydraulic line is routed through the second and fourth apertures.
