Unable to adjust Kubota GR2120 Mower seat

[Ray Cook]

I am unable to adjust the movement of the Kubota GR2129.
I have used the lever to release seat mechanism but no movement.
Is there a secret ??
Thanks
Ray

Hi,
I have the same manual, I have turned the (1) Seat sliding lever.
When I turn the (1) Seat sliding lever, I hear a click sound,(spring loaded returns to original position when released)
I assume The Click is a Release but unable to move seat.
Question: Should I pull on the seat sliding rod?
Thanks
Ray

Hi again,
I read the description again,
The operator's seat position can be adjusted forward and
backward by 150 mm (6 in.) range by pulling the seat
sliding lever.
I will try it in the morning !

Thanks for your help, Sometimes I read but, I don't really read correctly!!.
Have good Day
Ray
