1. An engine output control device for a working vehicle, comprising:
- a mode setting switch which can set any one from among a plurality of output modes;
a load detector which detects a load on said working vehicle; and
an engine controller which controls an engine based on any one engine output characteristic selected from among a plurality of engine output characteristics which are prepared in advance;
wherein said engine controller makes said plurality of engine output characteristics corresponding to at least one output mode among said plurality of output modes, and if an output mode which is made corresponding to said plurality of engine output characteristics is set by said mode setting switch, said engine controller selects any one among said plurality of engine output characteristics based on magnitude of said load which is detected by said load detector.

Abstract
An engine output control device and an engine output control method for a working vehicle capable of implementing low fuel consumption, and of providing the output required for working. The engine output control device of includes a mode setting switch which can set any one from among a plurality of output modes, a load detector which detects the load on the working vehicle, and an engine controller which controls an engine based on any one engine output characteristic selected from among a plurality of engine output characteristics which are prepared in advance.

9. An engine output control method for a working vehicle, comprising:
-
a load on said working vehicle is detected, and a plurality of output modes which can be selected by a user are provided; a plurality of engine output characteristics are made corresponding to at least one output mode among said plurality of output modes; and when an output mode which is made corresponding to said plurality of engine output characteristics is selected by said user, any one of said plurality of engine output characteristics is selected based on magnitude of the load which is detected.

10. An engine output control method for a working vehicle, characterized in that a plurality of engine output characteristics are made corresponding in advance to a first output mode in which an engine output is relatively increased and a second output mode in which said engine output is relatively decreased, respectively, and comprising
a step of detecting load on said working vehicle, when said first output mode is selected by a user; -
a step of, when said detected load belongs to a high load which is set in advance, setting a first high load engine output characteristic which is made corresponding in advance to said first output mode; a step of, when said detected load belongs to a low load which is set in advance, setting a first low load engine output characteristic which is made corresponding in advance to said first output mode, and in which the engine output is decreased below the engine output in said first high load engine output characteristic; a step of detecting said load on said working vehicle, when said second output mode is selected by said user; a step of, when said detected load belongs to a high load which is set in advance, setting a second high load engine output characteristic which is made corresponding in advance to said second output mode; and a step of, when said detected load belongs to a low load which is set in advance, setting a second low load engine output characteristic which is made corresponding in advance to said second output mode, and in which the engine output is decreased below the engine output in said second high load engine output characteristic.
