Can anyone help me, I have a l35 kubota tractor with the tl720 front bucket,I have no hydraulics to curle my bucket or to dump it but I do have the up and down motion.Any ideas what could be causing this, thanks
sounds like you might have a bucket cylinder that needs to be rebuilt. Not a big deal and not terribly expensive. It could also be a seal of o ring in the control unit. Before getting in to all that, check and be sure all the hydraulic quick connects are fully connected. Sometimes they can get bumped loose and appear to be connected. I have owned a dozen or so in the past. I'm remembering them to have quick connects. If they don't we will blame it on "maturity".
Also a quick test:
Swap the lift lines for the roll lines, if the roll works and the lift doesn't it's the valve or quick connectors.
If it still wont lift, again still could be a bad quick connect or a blown seal on a cylinder.
