Kubota L4200GST tractor - question about the operation of the gearbox.

licz3 · Mar 10, 2021

I have a question for users of the Kubota tractor with GST gearbox.
I have never come across this kind of gearbox and have owned a Kubota L4200GST since November.
How should a tractor behave when, for example, I gather a bucket of soil - is it normal that in higher gears the tractor simply stops as if it would disengage the clutch? The engine does not choke, the wheels do not turn and the tractor simply stops. The same is true when, for example, I am plowing - if I do not downshift to 3 or lower, the tractor stops.
Is this all normal or maybe some problems with the gearbox?

Drop down to lower gear(s). Might aggravate you because you are working slower, but ahhhh.. steadier.

Here is a good video that describes the GST. I like mine. There is a slight pause as you shift into a different gear. The pause is slightly longer if that gear change also involves a range change. If your pauses are longer than that, maybe you need a slight linkage adjustment.
