  • Patent number: 9045171
    Abstract: A work vehicle includes a fixed hood covering a rear area of an engine compartment housing an engine and an engine accessory, a swing axis extending through the rear area of the engine compartment in a transverse direction of the vehicle, and a swing hood swinging around the swing axis between a closed position and an open position. The swing hood tucks the fixed hood inside the swing hood and thus covers the fixed hood in the open position, and covers a front area and a middle area of the engine compartment and overlaps with a front end portion of the fixed hood in the closed position.

  • Patent number: 8991143
    Abstract: A work vehicle includes wheels and a mower unit that are driven by power from an engine, and a mower driving detecting section for detecting power transmission condition to the mower unit. An isochronous controlling section controls the engine in an isochronous control mode for maintaining an engine rotational speed at a predetermined fixed value, independently of an engine load. A droop controlling section controls the engine in a droop control mode for varying the engine rotational speed in dependence on the engine load. If power is transmitted to the mower unit, the isochronous control mode is selected.

  • Patent number: 7448192
    Abstract: A fill detection device for a grass container includes: 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.
