You should be able to use Kubota's front blade. I think they have two models one with manual angle and the other with hydraulic angle and heavier duty blade. Both have hydraulic lift.
The models are TG2754 and BX2763 respectively. They can be seen on Kubota's website. Kubota BX Blades
I don't remember the cost exactly as when I was shopping I was interested, but every dealer told me to get the FEL for a few hundred more. So the cost must be around $2k I would think.
