Hydraulics barely work when using enough to create heat. Will not run auger wagon even when cold.
What might be the problem.

We will need some more info, I am sure Tim S will offer some form of explosives.

Loader on the tractor? Is the problem new or has gradually appeared ? What brand and type of hydraulic oil ? Any nasty sounds or shuddering when the brakes are applied ?When was the last time the transmission screen and filter were changed? Does the acv valve return to the transmission case or have it been updated to the ported transmission filter return?
Standard pump was 13gpm at redline, option pump was 23 rpm.

No loader. Hy-guard, changed every year. Gradually gotten worse.

Does tractor have hyd hi-lo(rabbit-turtle on dash) or hyd ind pto? These 2 options have a long history of possible leaking supply tubes or seals. With engine running,3 pt raised look in hyd filler hole behind seat for moving oil. I'll also suggest to check/clean hyd sump screen(key 13) and check to be sure hyf filter relief valve(4-6) isn't stuck open
