Abstract
An implement for clearing brush and trees which includes a self-propelled vehicle and at least one boom mounted upon the vehicle. The boom is constructed for articulated motion of a distal end thereof. A cutting disk is operatively mounted for rotation to the distal end of said boom to cut brush and trees when rotated. A secondary power source is supported on the self-propelled vehicle and used to primarily power the cutting disk. The implement is configured to allow field replacement of a cutting wheel support cartridge.
Claims18
An implement for clearing brush and trees, comprising:
- a self-propelled vehicle;
- at least one boom mounted upon the vehicle;
- said boom being constructed for articulated motion of a distal end thereof;
- a cutting disk operatively mounted for rotation to the distal end of said boom to cut brush and trees when rotated;
- and
- a secondary power source supported on the self-propelled vehicle and used to primarily power the cutting disk.
An implement for clearing brush and trees, comprising:
- a cutting head frame;
- a motor mounted to the cutting head frame;
- a drive shaft operatively coupled to the motor for rotation;
- said drive shaft constructed to be selectively uncoupled from the motor;
- a bearing mechanism removably secured to the cutting head frame and supporting the drive shaft for the rotation;
- a cutting disk mounted on the drive shaft for rotation therewith;
- and
- wherein the bearing mechanism can be detached from the cutting head to facilitate replacement of the bearing mechanism and drive shaft.
An implement for clearing brush and trees, comprising:
- a self-propelled vehicle;
- at least one boom mounted upon the vehicle;
- said one boom being constructed for articulated motion of a distal end thereof;
- a cutting head frame mounted to the distal end of the boom;
- a motor mounted to the cutting head frame;
- a drive shaft operatively coupled to the motor for rotation;
- said drive shaft constructed to be selectively uncoupled from the motor;
- a bearing mechanism removably secured to the cutting head frame and supporting the drive shaft for the rotation;
- the bearing mechanism constructed to be detached from the cutting head to facilitate replacement of the bearing mechanism and drive shaft;
- a cutting disk mounted on the drive shaft for cutting brush and trees when rotated;
- and
- a secondary power source on the self-propelled vehicle used to primarily power the cutting disk.
An implement for clearing brush and trees, comprising:
- a vehicle;
- a primary engine supported and operatively coupled to the vehicle to move the vehicle across ground;
- a boom mounted upon the vehicle;
- said boom being constructed for articulated motion of a distal end thereof;
- a cutting disk mounted to the distal end of said boom for cutting brush and trees when rotated;
- and
- an auxiliary engine supported on the vehicle and providing power to rotate the cutting disk.
An implement according to claim 16 wherein the auxiliary engine provides power only to the cutting disk.
An implement according to claim 18 wherein the auxiliary engine provides power to the cutting disk and to at least one of the following:
- said cutting head frame for the selective pivot action of the cutting disk about the pivot axis;
- and
- said cutting head swivel for the selective swivel action of the cutting disk about the swivel axis.
