摘要： Provided is a tractor which allows continuation of a plowing work by appropriately elevating a plow when slip occurs in wheels. The tractor includes draft controlling means (34) for elevating the plow to a target machine body level value obtained by making reference to control information with a draft load value detected by a draft load sensor (S). The control information is set based on a target plowing depth set when the plow was set to a target plowing depth and a draft load value. When a slip ratio detected by a slip ratio acquiring means (37) exceeds a threshold value, in place of previously set control information, there is newly set control information which renders higher the target machine body level relative to a same draft load value, thereby to elevate the plow.

摘要： An engine speed control system for a work vehicle is disclosed. Storage means (56) stores a predetermined engine speed. A manually operated input device (37, 38) issues an instruction to retrieve the engine speed from the storage means (56). Engine speed control means (50) executes a constant speed control, whereby the engine speed stored in the storage means (56) is set as a target speed on the basis of a first input operation made using the input device (37, 38). The engine speed control means (50) further executes a stored speed change control for allowing the setting of the engine speed stored in the storage means (56) to be changed based on a second, different input operation performed using the input device (37, 38).

摘要： The engine speed control system for a work vehicle has a foot accelerator controller for carrying out foot accelerator control based on a pedal sensor, a hand accelerator controller for carrying out hand accelerator control based on a lever sensor, a manually operated input device, storage means for storing a predetermined engine speed, and a constant rotation controller for carrying out constant rotation control in which the engine speed stored in the storage means is used as the target rotational speed on the basis of an input to the input device. The constant rotation control is carried out when the input device has been operated in the case that the engine speed that corresponds to the output of the lever sensor is greater than an idling speed, and the constant rotation control is terminated when the input device is operated in the case that the engine speed that corresponds to the output of the lever sensor is equal to or less than the idling speed.

摘要： An engine controller (76) includes a first mode control module (81) for performing a first mode control in which a fuel injection amount in an engine (1) is obtained based on a first torque-engine rotational speed characteristic, and a second mode control module (82) for performing a second mode control in which the fuel injection amount is obtained based on a second torque-engine rotational speed characteristic. The first mode control module (81) has a first engine load estimation part (81a) for estimating an engine load based on a difference in rotational speed between a non-load engine rotational speed and an actual engine rotational speed, and the second mode control module (82) has a second engine load estimation part (82a) for estimating an engine load based on the fuel injection amount.
