<font color="blue">Let us know what pressure you had and such. I have the same tractor as you - the TC25D.</font>
My pressure is 1,825 psi at 2,600 rpm.
Remember, though, I had turned the set screw in 1/4 turn. So, my original pressure was 1,700 psi at 2,600 rpm. This jives with Spencer's test that indicated 1/4 turn equals 125 psi.
<font color="blue">Curious to see if you can raise your tires - I still can not (unless I curl the bucket) </font>
I wonder if the different capabilities are caused by following a different procedure?
1. Tractor running at 2,600 rpm.
2. Transmission in Neutral.
3. Parking brake off.
4. Curl bucket.
5. Push FEL control forward.
