摘要:
A work vehicle includes an engine, a PTO shaft driven by power from the engine, an operator's seat, an operator's presence sensor for detecting presence/absence of an operator at the operator's seat, and an automatic engine stop unit operable to automatically stop the engine in response to detection of the operator's absence at the operator's seat. The work vehicle includes a utility member for the vehicle selectively movable between a use position and a non-use position, a non-use state detecting sensor for detecting movement of the utility member to the non-use position, and an override unit operable to override the automatic engine stop function of the automatic engine stop unit, the override unit providing an override signal to the automatic engine stop unit in response to detection by the non-use state detecting sensor of the movement of the utility member to the non-use position.

A friction clutch mounted in a transmission case (25) or the like and connected between a drive shaft (14) for receiving engine power and a driven shaft (15) for receiving power from the drive shaft and transmitting the power to a power takeoff shaft (11). The friction clutch includes a first sleeve (17) connected to the drive shaft, a second sleeve (16) connected to the driven shaft, friction disks (18, 19) disposed between the first sleeve and the second sleeve, the friction disks being switchable between a clutch engaging state to enable power transmission between the first sleeve and the second sleeve, and a clutch disengaging state to disable the power transmission, and a clutch piston (20) movable between a first position to place the friction disks in the clutch engaging state, and a second position to place the friction disks in the clutch disengaging state. The friction clutch further includes a brake mechanism (B) for braking rotation of the driven shaft when the friction disks are in the clutch disengaging state. The brake mechanism includes a first braking member (26) operatively connected to the clutch piston, and a second braking member (24) for contacting the first braking member when the clutch piston is moved to the second position. The second braking member is rotatable through a predetermined range with the first braking member.

A tractor transmission includes a change speed mechanism, a shift lever (30) for shifting the change speed mechanism, a super-reduction mechanism (16) for decelerating and outputting power inputted thereto, the super-reduction mechanism having a larger reduction ratio than the change speed mechanism, and an overdrive mechanism (45) for accelerating and outputting power inputted thereto. A single switching device (29) is provided for operating both the super-reduction mechanism and overdrive mechanism. The switching device is shiftable, when the super-reduction mechanism is in neutral, from a state of operating the super-reduction mechanism to a state of operating the overdrive mechanism.

A fixing belt for fixing the toner image on a recording medium includes an electroformed nickel endless belt body. The belt body exhibits hardness higher at the rear surface than at the front surface after heated at 350° C.
摘要:
A transmission for a tractor comprising a power takeoff line change speed gear mechanism, propelling line change speed gear mechanisms and a backward and forward drive switching mechanism. The propelling line change speed gear mechanisms include a main change speed mechanism, an auxiliary change speed mechanism and a front wheel change speed mechanism. The power takeoff line change speed mechanism, and the main and auxiliary change speed mechanisms somewhat encircle a longitudinal center line transversely of the transmission. The backward and forward drive switching mechanism and the front wheel change speed mechansim are juxtaposed in a region immediately forwardly of the change speed machanisms B, C and E. Further, the drive switching mechanism, the auxiliary change speed mechanism and the front wheel change speed mechanism F are disposed on one lateral side of a longitudinal plane from a front end of the tractor to a rear end at a substantially mid-position of the transmission while the power takeoff line change speed mechanism and the main change speed mechanism are disposed on the other lateral side thereof.

The present invention provides a fixing belt adapted to move circularly and cooperate with a pressing member to form a nip region for fixing an unfixed toner image on a recording medium, capable of achieving a desirably enhanced durability even under high-temperature atmosphere. The fixing belt comprises a substrate formed of an endless-shaped electroformed sheet consisting essentially of a nickel-carbon alloy containing 0.05 to 0.12 mass % of carbon. The carbon content may be adjusted in proportion to the amount of a secondary brightening agent to be added to an electrolytic bath or to a cathode current density to be sent to the electrolytic bath. The secondary brightening agent may be 2-butyne-1,4-diol. In the fixing belt of the present invention, the substrate may have a surface provided with a releasing layer which may be formed as a single layer or multilayer made of a material having heat resistance and non-adhesive, such as silicone rubber, fluorine rubber, fluororesin, or their mixture.

摘要:
An agricultural tractor in which two sets of pedals are mounted on the tractor body forwardly and rearwardly with the rearward pedals at a higher position than the forward pedals. A seat can be selectively fixed at a rearward position opposed to the forward pedals or a forward position opposed to the rearward pedals, the forward position of the seat being higher than the rearward position. A steering wheel can be fixed to either a forward or rearward position corresponding to the position of the seat.
