Abstract
An improved stump grinding machine includes a frame structure having an engine mounted thereon. A boom has a proximal end and distal end and is pivotally mounted to the frame structure at its proximal end. A grinding wheel is rotatably mounted to the distal end of the boom. A power train arrangement transmits power from the engine to the grinding wheel. The power train arrangement includes an idler shaft rotatably mounted on the frame structure. The boom is pivotally mounted to the frame structure independently of the idler shaft.
Claims29
A stump grinding apparatus, said apparatus comprising:
- a frame structure supported by at least one wheel to facilitate movement of said stump grinding apparatus from place to place;
- an engine supported by said frame structure;
- a boom having a proximal end and a distal end, said boom being pivotally mounted to said frame structure at said proximal end thereof;
- a grinding wheel rotatably mounted to said distal end of said boom;
- and
- a power train arrangement for transmitting power from said engine to said grinding wheel, said power train arrangement including an idler shaft mounted on said frame structure for rotation so as to be coaxial with a pivot axis of said boom,
- wherein said boom is pivotally mounted to said frame structure independently of said idler shaft.
A stump grinding apparatus, said apparatus comprising:
- a frame structure;
- an engine supported by said frame structure;
- a boom having a proximal end and a distal end, said proximal end including a boom tube pivotally mounted to said frame structure by at least one first bearing so that said boom is pivotally mounted to said frame structure;
- a grinding wheel rotatably mounted to said distal end of said boom;
- an idler shaft extending through said boom tube and mounted for rotation on said frame structure by a plurality of second bearings;
- and
- a power train arrangement for transmitting power from said engine to said idler shaft and from said idler shaft to said grinding wheel.
A mounting arrangement comprising:
- a frame;
- a pivoting boom structure having a proximal end and a distal end, said proximal end being pivotally mounted to said frame by at least one first bearing;
- a first shaft rotatably mounted on said frame so as to be coaxial with a pivot axis of said boom structure, said first shaft being mounted to said frame by a plurality of second bearings;
- a tool rotatably mounted to said distal end of said boom structure;
- and
- a power train arrangement for transmitting power from said first shaft to said tool,
- wherein said boom structure is pivotally mounted to said frame independently of said first shaft.
