Type of steering on Kubota L3200

[Rosohatica]

Hello again, I am into a process of tractor technical specification which is prequisite for getting a licence plates and they asked me what kind of steering it has. I didnt know. I assume it is not a servo but mechanical, right? Yet, its rather easy to steer. Does somebody have a name for it?

Hydraulic/hydrostatic steering.

Hydraulic/hydrostatic steering.

Thanks.

Thanks.

I do not think you have hydrostatic steering but instead a regular steering box with the power steering build into it...

From the WSM:
This integral power steering mechanism consists of the following two major components as shown above: hydraulic control valve and steering force assist hydraulic cylinder. The control valve is housed in the casing and composed of sleeve (3), input shaft (1) and other parts. The hydraulic cylinder, on the other hand, is composed of gear box (7) (cylinder tube), ball nut (4) (piston) and other parts. When the steering wheel is turned, the reaction force from the tires is exerted through the sector shaft (6) onto the main shaft (5). The torsion bar (2) is then twisted to make a gap between the input shaft (1) and sleeve (3). Such gap activates the valve to switch the oil flow direction. The sector shaft's pinion, which comes in mesh with the ball nut's rack, is tapered along the teeth. In this way, the sector shaft (6) that turns by the adjust screw (8) changes the clearance between the rack and pinion, adjusting the play of the steering wheel. (Tighten the adjust screw and the play becomes smaller, and vice versa.).

This is the same type of power steering found on many cars in the year 2000

I was thinking that my L3200 suicide knob was always at the same place when going straight, and the L4240 was the first one where the SK could be anywhere. That would be consistent with going from power steering to hydraulic steering.
