Seeking a tractor mechanic

[My 2 cents]

Hydraulic systems are generally what I would call self-bleeding. Fill the fluid reservoir, start the engine and run all of the implements stop to stop several times, i.e., raise the bucket to its highest point and back down to the lowest point several times, then same with the bucket tilt, and same with any other hydraulic functions. Then refill the reservoir.

Have tried this yet?
