Buying Advice Kubota L3400HST vs L2800HST

[Fallon]

Are both tractors HST transmissions?
L2800 around that year has jerky hyd.

I assume you mean a jerky 3pt? Both machines will be equally likely to have that.

The issue presents when you try to do fine grained movements. Try to lift the 3pt 1" or so & it could be really rough. Moving larger distances were less likely to be as harsh. Some were really rough no matter what.
