$3,750 · 300 mustang skidster

Runs good till my friend blew a hose. He replaced the hose and he replaced the hose and decided to replace hydraulic fluid. It drives and the arm lifts up but the bucket doesn’t go up or down. People said there was a airlock but I don’t have time to work on it I’m just asking roughly $3750 you can text my number if you have any questions. It will be sold as is the wheels drives don’t leak and tires are in good shape. (Text my number for photos, since i don’t know how to upload them from my career roll)
