PROBLEM TO BE SOLVED: To improve operability of the steering swivel of a tractor by providing a steering brake of the left and right rear wheels and a pair of the left and right brake handles at a floor part or dash board part of a steering handle side part. SOLUTION: A floor or dash board part 2 of a steering handle 1 side part is provided with a pair of the left and right brake handles 6 interlocking via a steering brake 4 and a brake operation mechanism of left and right rear wheels 3 and capable of being operated from an operator seat 7. Thereby, the operator manually operates a brake handle 6 during steering swivel while performing steering operation with a steering handle 1 with the operator sitting on the operator seat 7 on the tractor body and brakes a steering brake 4. For the brake handle 6, the interlocking part with the brake operation mechanism is positioned at a dash board 2 or the floor part and of relatively long protruded arm construction, therefore, operability is lightened, and proper, easy steering brake operation can be performed. |
