A tractor includes a working motor, a work machine including a roller configured to rotate by an output from the working motor, a support mechanism configured to support the work machine such that a working posture and a retracting posture are achievable, and a control device. The control device executes: an adherence amount acquisition process of acquiring an estimated adherence amount as an estimated value for the amount of mud attached to the roller; and a mud removal process of, when the estimated adherence amount is equal to or more than a determination adherence amount, removing the mud from the roller by driving the working motor in a state where the work machine takes the retracting posture.

Tractor

Provided is a control device of a working vehicle including a prime mover and a driving mechanism that drives an implement based on power of the prime mover, wherein the control device is configured to obtain a steering angle of the working vehicle, and detect switching between tasks performed by the working vehicle in a farm field, when the steering angle is equal to or greater than a predetermined angle indicating the switching between tasks.

A method for a SiC single crystal that allow prolonged growth to be achieved are provided. A method for producing a SiC single crystal in which a seed crystal substrate held on a seed crystal holding shaft is contacted with a Si&#x2014;C solution having a temperature gradient such that a temperature of the Si&#x2014;C solution decreases from an interior of the Si&#x2014;C solution toward a liquid level of the Si&#x2014;C solution, in a graphite crucible, to grow a SiC single crystal, wherein the method comprises the steps of: electromagnetic stirring of the Si&#x2014;C solution with an induction coil to produce a flow, and heating of a lower part of the graphite crucible with a resistance heater.

An electronic control unit executes a delay control and a load compensation control. In the delay control, the period from when an engine stop request for an engine is made to when the engine is actually stopped is extended. In the load compensation control, the engine power is adjusted according to the driving load of auxiliary devices. Further, if the engine stop request is made during operation of a compressor, which is one of the auxiliary devices, the electronic control unit executes a power reduction control, in which ignition timing is retarded to temporarily reduce the engine power. As a result, in an internal combustion engine that executes the delay control, sudden increases in the engine speed that are likely to occur when an engine stop request is made during operation of auxiliary devices are reliably suppressed.
