Renault 90-34 TX Controls

[Jezza71]

Hi we've just bought a Renault 90-34 TX and are trying to figure out the controls as we don't have a manual.
does anyone know what this small pull knob behind the controls on the right is ? it has a small cable that goes to a block on the top of the axle

It's something to do with hydraulics I think. We've had 90-34s since the late 80s and I've got one here now with 14k hrs on the clock and have never touched that knob

Yeah it’s hydraulic flow control, never touched mine either.

Same story here. Let one go a few years ago after 12.5k hours. Never gave any bother and still would have done the same again. Great little tractor. Also never touched that knob.

Thanks for the replies, I presumed it wasn't used much as the cable is seized, this one only has 7k hrs so should last us a while

It's the slow/fast response of lift arms for when ploughing,
