my JD 2355 have no hydraulics

[kool aiden]

I was plowing the driveway using my 2018 John Deere 2355 and one of the lines on the plow blew. It suddenly just stops working.
then, I drained the fluid and replaced it. I can drive forward and reverse it now, but nothing else. there's no pressure in the hydraulics, no PTO, and power steering.
I checked the valve by the rear right tire, all okay. Any thoughts on what I should check next? I really need to fix this

I believe you have lost hydraulic prime after the fluid change. Start by checking the filter and suction screen, and make sure the transmission pump is feeding the front pump. To bleed out any air, crack the front pump inlet, if there’s no flow you should look for a suction leak or a charge pump issue.

This can also be because of a blockage in the system. you need to look for any damage to hydraulic lines or fittings that can be caused by the initial line failure
then check for any leaks in the hydraulic system, bcs a large leak could cause a loss of pressure

Appreciate the helpful advice here. The points about losing hydraulic prime and checking for blockages are spot on. It's a good reminder that it's not always just a line failure, but also what happens after. Thanks for sharing your experiences this kind of detail keeps the discussion useful for everyone.
