| 20080236125 | Climb-Up Assist Structure for Mower Unit - A mower unit configured to be supported to a work vehicle at a position between front wheels and rear wheels, comprises a mower deck; at least one blade supported by the mower deck; a climb-up assist member in which an inclined surface is formed for assisting the wheels in climbing over the mower unit; and a connecting device for detachably connecting the climb-up assist member to the mower unit in a service position in which the inclined surface assists the wheels in climbing over the mower unit. | 10-02-2008 |
| 20080302077 | Device for limiting lowering of implement on working vehicle - A working vehicle includes a vehicle body supported by a plurality of wheels; an implement supported by the vehicle body via a link mechanism such that the implement can be raised and lowered, the implement being permitted to be lowered under its own weight; an abutting member that moves in tandem with the raising and lowering movement of the implement; a receiving piece for limiting the lowering of the implement under its own weight by receiving a first portion of the abutting member; and a manually operable first operating piece for changing the position of the receiving piece between a receiving position and a retracted position, wherein a lowering limiting position is set to a vertical position that is closer to the upper limit of a range of the raising or lowering movement of the implement than to the lower limit of that range. | 12-11-2008 |
| 20090013942 | Cooling Structure for a Work Vehicle - A cooling structure for a working vehicle with a transmission disposed rearwardly and downwardly of a driver's seat and having a hydrostatic transmission, and an air-cooled engine disposed rearwardly of the transmission. The cooling structure comprising a fan for cooling the engine and a fan for cooling the transmission mounted on a rotary shaft operatively connecting the transmission with an output shaft of the air-cooled engine, the fans being configured such that air flows generated by the fans move from adjacent the transmission toward the engine; an oil cooler for cooling fluid supplied to the hydrostatic transmission, the oil cooler being disposed between the fan for cooling the engine and the fan for cooling the transmission, and disposed to face each of the fans; and an air guiding plate disposed at a position higher than the oil cooler for guiding air to regions of the fans. | 01-15-2009 |
| 20090241498 | Dust Removal System for a Riding Lawn Mower - A dust removal system for a riding lawn mower, comprising an engine, a speed change device disposed outside of an engine compartment, and a universal coupling inserted through an opening provided to a separating wall in order to connect an output shaft of the engine and an input shaft of the speed change device. The dust removal system is composed of a perforated board which rotates integrally with the output shaft and around the axis of the output shaft in order to impede grass cuttings from flowing into the engine compartment through the opening, the perforated board having an insertion hole formed in the center to allow the universal coupling to be inserted; and a seal unit for substantially sealing the space between the universal coupling and the peripheral edge of the insertion hole. The seal unit has a radially extending flange formed on the universal coupling, and a ring member in which one end is mounted on the flange and the other end is in contact with the peripheral area around the insertion hole. | 10-01-2009 |
