Claim 3
Dependent Claim
69 words
A cutter mechanism as descrIbed in claim 1 further characterized in that said yoke means is pivotally mounted on said base support housing for pivotal movement through an arc of substantially 180* whereby said yoke means can be positioned laterally on either of two opposite sides of said housing, and in that said yoke means includes releasable holding means for holding it selectively in either of such lateral positions.
Claim 4
Dependent Claim
117 words
A cutter mechanism as in claim 2 further characterized in that said releasable holding means includes a latch receiving notch portion defined on said yoke means and wherein a pair of spring biased and movable latch elements are provided, one such element being located on each of two opposite sides of the base support housing, said movable latch elements being adapted to engage said latch receiving notch portion selectively as the yoke means is positioned laterally at one side of said base support housing or the other, said spring biased and movable latch elements being detailed to be released from said latch receiving notch element in response to a predetermined pressure being applied to said boom means.
Claim 5
Dependent Claim
66 words
A cutter mechanism as described in claim 3 further characterized in that said pair of latch elements are operatively associated with said yoke control means and wherein alternate ones of said latch elements are rendered effective in response to said yoke control means moving said yoke to a laterally extending position adjacent a lateral side of said housing and adjacent said one of said latch elements.
Claim 6
Dependent Claim
105 words
A cutter mechanism as defined in claim 1 further characterized in that said yoke control means includes hydraulic power means for moving said yoke means about said vertical axis whereby said yoke with said boom and cutter head can be positioned adjacent one lateral side edge of said support housing and can be moved to an opposite lateral side edge of said support housing and wherein said hydraulic power means includes releasable means operatively associated with said control means for releasing said yoke means from said laterally extending position in response to a predetermined amount of pressure being applied to said boom and cutter head.
Claim 7
Dependent Claim
103 words
A cutter mechanism as described in claim 1 further characterized in that said yoke control means includes a pair of hydraulic control cylinders and a pivotally mounted control plate and wherein one of said control cylinders is supported between said housing and said control plate and said other hydraulic cylinder is supported between said yoke and said control plate, whereby operation of one of said hydraulic cylinders will effect movement of said yoke and said boom through an arc of substantially 90* and operation of said second hydraulic cylinder will effect movement of said yoke and boom through a second arc of 90*.
Claim 8
Dependent Claim
84 words
A cutter mechanism as described in claim 1 further characterized in that said boom control means includes a bell crank assembly having one end coaxially mounted relative to said horizontal pivot axis of said boom, said bell crank including spring biasing connecting means connected to an opposite end of said bell crank and to said boom at a position spaced from said horizontal axis and wherein said control means includes a hydraulic cylinder operatively connected to said bell crank and said yoke support means.
Claim 9
Dependent Claim
96 words
A cutter mechanism as described in claim 1 further characterized in that said cutter head includes a pair of pivotally mounted flange means supported for pivotal movement between a retracted inoperative position and an extended position wherein said flanges are angularly disposed in the plane of said cutter blade for providing a shield for debris being cut by said cutter blade and wherein control means is operatively associated with each of said flange means and said operable power means for effecting movement of said flange means from said extended operable position to said retracted inoperable position.
Claim 10
Dependent Claim
148 words
A cutter mechanism for use in cutting vegetation, detaiLed for attachment to a prime mover vehicle and comprising a base support housing including means for attachment of said housing to said vehicle, and wherein said housing includes a self-contained hydraulic control system, said attachment means including a power take off connection and a plug-in electrical control means, a cutter head including a cutting blade having control means operatively associated with said hydraulic control system for effecting operation of said cutting blade, and means for supporting said cutter head on said base support housing, said cutter head including a depending flange for providing a lateral shield against objects thrown outwardly by said cutting blade, said flange including two movable sections, each section being mounted for movement to and from an extended shielding position and means operatively associated with each of said sections for effecting such movement of said sections.
