Won't move forward or backward

[Seminole Ted]

I have a Kubota L 4600 HST with 182 hrs. It was moving sluggish, I changed the hydraulic filters. After warming tractor up it ran good for 10 minutes and then would not move forward or backward. The front end loader moves perfect. The engine runs good. Any suggestions?

SWAG, air in the system. Run your pedals FRFRFRFRFRFRFR for a few minutes. If you start getting motion continue till the air is out. Otherwise is there a bleed screw on the hydro part of your hydraulic system to let the air out???

Thanks , I'll research and see if it has one.
