Abstract
Abstract Disclosed is a combination of a frame, a mount, and a boom, wherein the boom retains a workpiece, such as a mower, about its free end and is rotationally attached to a pivotal mount at its other end. The pivotal mount or rocker arm is attached to the frame and permits the boom and workpiece to be centered over the frame for transport. The entire assembly preferably is mounted on the back bed area of a truck or tractor.

Claim 1
Independent Claim
204 words
In combination, a frame, a mount, and a boom; said boom having at least one section attached to said mount at one end and capable of retaining a mowing unit about its free end, means pivotally attached to said section and said mount for adjustably rotating said section about its point of attachment to said mount, the axis of said rotation being horizontal, said mount being pivotally attached to said frame about a first pivot point and having means associated therewith for adjustably pivoting said mount about its pivotal attachment to said frame, the associated means being attached to said mount at a second pivot point, the axis of rotation of said second pivot point being horizontal, said mount pivoting means being cooperatively operable for adjustably positioning said boom section about said first pivot point to (1) a generally horizontal position extending away from said frame for operation of said mowing unit and (2) over the frame at an angle of greater than 90° from said horizontal position, said mowing unit and said boom being positioned over said frame thereby, and the frame being mounted on a vehicle having at least two axles and said frame being directly connected to one of said axles.
Claim 2
Dependent Claim
204 words
In combination, a frame, a mount, and a boom; said boom having at least one section attached to said mount at one end and capable of retaining a mowing unit about its free end, means pivotally attached to said section and said mount for adjustably rotating said section about its point of attachment to said mount, the axis of said rotation being horizontal, said mount being pivotally attached to said frame about a first pivot point and having means associated therewith for adjustably pivoting said mount about its pivotal attachment to said frame, the associated means being attached to said mount at a second pivot point, the axis of rotation of said second pivot point being horizontal, said mount pivoting means being cooperatively operable for adjustably positioning said boom section about said first pivot point to (1) a generally horizontal position extending away from said frame for operation of said mowing unit and (2) over the frame at an angle of greater than 90° from said horizontal position, said mowing unit and said boom being positioned over said frame thereby, and the frame being mounted on a vehicle having at least two axles and said frame being directly connected to one of said axles.
Claim 3
Dependent Claim
31 words
The combination of claim 1 wherein said boom has between two and five sections, each section being rotationally attached to each other and said sections have adjustable rotating means associated therewith.
Claim 4
Dependent Claim
16 words
The combination of claim 2 wherein each of said means is a piston and cylinder unit.
Claim 5
Dependent Claim
49 words
The combination of claim 1 wherein said frame additionally has a first support member for supporting said boom section attached to said mount and a second support member for supporting said mowing unit when said boom section attached to said mount is in said greater than 90° angle position.
Claim 6
Dependent Claim
89 words
The combination of claim 4 wherein said pivoting means for said mount is capable of rotating said mount, and thus said boom section attached to said mount, from said greater than 90° angle position to a 90° angle position from said horizontal position, and said rotating means for said boom section attached to said mount is capable of rotating said boom section from said 90° position to said horizontal position, both of said means capable of rotating said boom section between about 110° and 160° from said horizontal position.
Claim 7
Dependent Claim
65 words
The combination of claim 5 wherein said frame also has attached thereto an adjustable counterweight having a piston and cylinder unit associated therewith for moving said counterweight away from said frame to counter balance said boom and mowing unit when said boom section attached to said mount is in a position from between said horizontal position and a position about 90° from said horizontal position.
Claim 8
Dependent Claim
64 words
The combination of claim 1 wherein said frame also has attached thereto an adjustable counterweight having a piston and cylinder unit associated therewith for moving said counterweight away from said frame to counter-balance said boom and mowing unit when said boom section attached to said mount is in a position from between said horizontal position and a position about 90° from said horizontal position.
Claim 9
Dependent Claim
16 words
The combination of claim 1 wherein each of said means is a piston and cylinder unit.
Claim 10
Dependent Claim
89 words
The combination of claim 1 wherein said pivoting means for said mount is capable of rotating said mount, and thus said boom section attached to said mount, from said greater than 90° angle position to a 90° angle position from said horizontal position, and said rotating means for said boom section attached to said mount is capable of rotating said boom section from said 90° position to said horizontal position, both of said means capable of rotating said boom section between about 110° and 160° from said horizontal position.
