LT 4300L no hydrolic pressure

[steveaulick]

Parked my tractor one evening, came out the next morning and it has rained and froze. Started up the tractor and nothing worked, no steering, no pto, no 3 point hitch, no fork control, nothing. The tractor only has 300 hrs on it . changed the filter, plenty of hydrolic fluid. Seems to build pressure to the fork controls but only pumps air. Any help ??

Just looking at were you are how cold is it there? Does your fluid look clear or is it milky looking?

Hummm that's odd. I wonder if water got inside something, froze and cracked it? Since it's not barfing fluid (I assume) I'd look at the pickup line for the pump. If you find nothing try repriming the pump.

It is very common for the suction hose to the hydraulic pump to crack letting it suck air.
