Device for treating cut fodder and mower employing such a treatment device

A mower comprising:

• at least one cutting mechanism and at least one treatment device, wherein said at least one treatment device includes:
• a treatment rotor rotatable about an axis of rotation, said treatment rotor and said axis of rotation both extending, during operation of said treatment device, so as to be approximately transverse to a direction of forward travel and so as to be approximately horizontal;
• a first support located near a first end of said treatment rotor and including a first bearing in which said first end of said treatment rotor is guided during a rotation thereof;
• a second support located near a second end of said treatment rotor and including a second bearing in which said second end of said treatment rotor is guided during said rotation thereof;
• and
• a driving device for driving said treatment rotor, said driving device including a drive member and a transmission device, said transmission device including:
• a first wheel mounted on an output shaft of said drive member;
• a second wheel mounted on said first end of said treatment rotor;
• at least one endless transmission member wound around said first wheel and said second wheel;
• a tension regulating mechanism for regulating a tension in said at least one endless transmission member, wherein said tension regulating mechanism includes said first bearing of said first support and said second wheel of said transmission device of said driving device such that both of said first bearing and said second wheel move away from said first wheel to attain a desired position of adjustment;
• and
• retaining means for retaining said first bearing and said second wheel in said desired position of adjustment.

A treatment device configured to treat cut fodder, said treatment device comprising:

• a treatment rotor rotatable about an axis of rotation, said treatment rotor and said axis of rotation both extending, during operation of said treatment device, so as to be approximately transverse to a direction of forward travel and so as to be approximately horizontal;
• a first support located near a first end of said treatment rotor, said first support including a first bearing in which said first end of said treatment rotor is guided during a rotation of said treatment rotor;
• a second support located near a second end of said treatment rotor, said second support including a second bearing in which said second end of said treatment rotor is guided during said rotation of said treatment rotor;
• and
• a driving device configured to drive said treatment rotor, said driving device including a drive member and a transmission device, said transmission device including:
• a first wheel mounted on an output shaft of said drive member,
• a second wheel mounted on said first end of said treatment rotor,
• at least one endless transmission member wound around said first wheel and said second wheel, and
• a tension regulating mechanism configured to regulate a tension in said at least one endless transmission member by movement of said treatment rotor, wherein said tension regulating mechanism includes said first bearing of said first support and said second wheel of said transmission device of said driving device such that both of said first bearing and said second wheel move away from said first wheel to attain a desired position of adjustment;
• and
• retaining means configured to retain said first bearing and said second wheel in said desired position of adjustment.
