A tractor steering and braking arrangement has a substantially vertically extending structural support column 11 for connection at a lower end 12 to a floor 13 of a tractor cab and carrying means 18 to support a steering wheel 15 at its upper end. At least one hydraulic master cylinder 29, 30 for operation of brakes of the tractor is supported within the column 11. The master cylinder 29, 30 includes an operating rod 27, 28 and an associated piston which is moved substantially vertically by an associated brake operating pedal 19, 20. The pedal is positioned at one side of the structural support column 11 and supported for pivoting from the column. Where separate left and right brakes are used, separate left and right master cylinders are mounted vertically within the support column 11. Both pedals are also mounted for pivoting from the column at a position 21 inside the column.
