2305 John Deere hydraulics

[Boznaros]

I have a 2305 John Deere with a loader and belly mower. I dont have any auxiliary hydraulic. My issue is after the tractor has ran a while the loader slows down and I can’t get the mower deck to raise. Any suggestion?

How many hours do you have on this tractor? First thought with the little bit of information here is that the hydraulic pump is worn out. When the oil warms up and the oil becomes more viscous, the pump pushes less oil through the system lowering the pressures.

700 hours

If I remember correctly it is a 2010 so not a lot of hours for this tractor

Not many hours for pump failure. The only way to determine what is going on is to put a pressure gauge on the hydraulics.
When the oil is cold, can you pickup the front of the tractor with the loader?

Following. Curious to hear outcome.

Yes even when it is warm it will pick up the front it is just slow doing so

Very interesting. What you say would indicate good pressure, just poor flow?

Have you checked hydraulic fluid level? Fluid condition, is it milky in color? Does this machine have a screen for the fluid? Just some initial things to go over.

Also, do you have to rev the engine to do this when the oil is warm vs idle to mid rpm when it is cold?
