M5950DT No Hydraulics

It has two pumps. Cant comment on appearances. The PS pump is supplied by an external reservoir. The implement pump is supplied by the main sump.

Have you ever heard of the hydraulic system needing bleeding? I don't know how long the hyd. filter has been on tractor but the fluid is clean. I'll change filter just to be sure it's ok. It has a old Fram P1653A. No sump screen or filter correct?

The system will bleed itself but you may need to help the pump establish prime. Put on a clean filter and check/replace suction side hoses and clamps to make sure there are no vacuum leaks. If it still does not self prime take the top pipe off the pump and pour a liberal spoonfull of clean oil in the port.

Give me the serial number of the tractor so I can see about a pump source.

Serial# M5950DTF-051015. Can you tell what year it is by the serial# ?

Before you jump to expensive and time confusing conclusions test the pump.

Have you added oil to the port on top of the pump ?

The serial number will not give you a date, as the tractors date is the date it's sold.
Take the serial number to a dealer and have them look it up.
FYI: Your stated serial number has one too many digits.
You sure that the first 0 is and 0 and not a O with a K inside of it?

Look at these connections for wet fittings / lines, that can cause an air lock.

On that model it's more likely to have a drive issue then a all out pump failure.
