| 1. A fill detection device for a grass container, comprising:
a detection switch;
a pivot sensor that is fastened inside the grass container, that can actuate the detection switch as a result of contact with
cut grass, and whose position can be changed between a raised non-detection position and a lowered detection position, the
pivot sensor having:
a first pressure-sensing surface that faces generally upwardly when the pivot sensor is in the non-detection position; and
a second pressure-sensing surface that is linked to the first pressure-sensing surface, and that faces generally substantially
rearwardly when the pivot sensor is in the non-detection position, wherein
the pivot sensor is fastened to a mounting portion that can be fastened to the grass container, the pivot sensor including
a biasing spring and a support arm that is linked to the first pressure-sensing surface, one end of the biasing spring biasing
the pivot sensor to the non-detection position by being coupled to the support arm, and the other end of the biasing spring
being coupled to an adjusting member whose position can be changed in a vertical direction.
