It doesn't look too bad, but I agree with cus_deluxe.
It is a lot better (and cheaper) to be proactive and replace it now rather than wait for it to rupture.
Remove the hose and take it to a tractor or heavy equipment repair shop, or auto parts store that makes them.
Shouldn't be too expensive.
Cheaper than replacing the hydraulic fluid, cleaning up the mess and being down at an inconvenient time.
