An implement comprising a first handle, on which are disposed control elements for the implement, and a second handle. The first handle is adjustable between a first operating position for a two-handed operation in which the implement is adapted to be guided by both the first handle and the second handle, and a second operating position for one-handed operation in which the implement is adapted to be guided by the first handle.

We claim: 1. An implement, comprising: a first handle, on which is disposed a control element in the form of a throttle trigger for a drive motor of the implement; a second handle, wherein said first handle is adjustable between a first operating position for a two-handed operation in which the implement is adapted to be guided by both said first handle and said second handle, and a second operating position for one-handed operation in which the implement is adapted to be guided by said first handle; and a handle frame, wherein said first handle and said second handle are disposed on said handle frame, further wherein said first handle and said second handle are pivotable together with said handle frame about a common first axis between said first and second operating positions, further wherein said first handle is mounted on said handle frame in such a way as to be rotatable relative to said handle frame about a longitudinal direction of said first handle about a second axis, further wherein said first handle is adapted to alternatively be secured to said handle frame in said first and said second operating positions, further wherein a pivot angle of said first handle about said second axis corresponds approximately to a pivot angle of said handle frame between said two positions about said first axis, and wherein said first handle is rotatable about said second axis in a direction opposite to the pivoting direction of said handle frame about said first axis such that in said first and second operating positions said throttle trigger is adapted to face generally the same direction relative to said implement. 2. An implement according to claim 1, wherein said second handle is adjustable between an operating position for said two-handed operation and a non-operative position for said one-handed operation. 3. An implement according to claim 1, wherein said handle frame is adapted to be pivoted about said first axis of rotation between said two operating positions by about 90°. 4. An implement according to claim 1, wherein said handle frame is formed from a bent tubular portion. 5. An implement according to claim 1, wherein in said operating position for said two-handed operation, ends of said two handles that face away from said handle frame are inclined relative to one another. 6. An implement according to claim 1, wherein said first handle is adapted to be pivoted by approximately 90° relative to said handle frame between said first operating position and said second operating position. 7. An implement according to claim 1, wherein said first handle is secured to said handle frame via a fixing structure that in said first and second operating positions is secured to said handle frame in different positions. 8. An implement according to claim 1, wherein said implement has a tubular section, and wherein said two handles are secured to said tubular section. 9. An implement according to claim 8, wherein in said operating position for said two-handed operation, said two handles are disposed in a plane that lies transverse to a longitudinal direction of said tubular section, and wherein in said operating position for said one-handed operation, said two handles are disposed in a plane that lies approximately parallel to said longitudinal direction of said tubular section. 10. An implement according to claim 8, wherein in both of said operating positions, said first handle, relative to a longitudinal direction of said tubular section, is disposed generally in the region of the same plane, which extends transverse to said longitudinal direction of said tubular section. 11. An implement according to claim 8, wherein said tubular section has a distal end from said first pivot axis, and wherein in a non-operative position, said second handle is disposed in a longitudinal direction of said tubular section that is closer to said distal end than said first handle. 12. An implement according to claim 8, wherein in said operating position for said one-handed operation, said first handle and said second handle are inclined relative to a longitudinal direction of said tubular section. 13. An implement according to clam 8, wherein a handle frame is provided, and wherein a section of said handle frame extends on a longitudinal side of said tubular section that is opposite said two handles. 14. An implement according to claim 8, wherein said handle frame is secured via a detachable clamp to said tubular section, and wherein said clamp is provided with a mounting support in which said handle frame is disposed in such a way as to be rotatable about said first axis of rotation. 15. An implement according to claim 1, wherein said implement is an implement that is adapted to be carried on the back of an operator. 16. An implement according to claim 15, wherein said implement has a blower tube, and wherein said implement has a tubular section that is a section of said blower tube.
