Have a 7600 that will spin brush hog but after it warms it will not. It has dual power. Where should I look? Thanks

You'll need to make up a tee fitting for the low pressure circuit to check the pressure. I made one of my own by taking an existing dual power tee and tapping it for 1/8" pipe thread.

Once you have the gauge installed, check pressures with the PTO on versus off, and with the dual power in low versus high. Look for a large drop in pressure while shifting. I suspect that the problem is in the high range of your dual power. That's the usual culprit.

The pto and dual power run off the low pressure pump that is part of the transmission pump. So not to confuse with mega flow pumps on other models.

Would get service manual and do the tests to see where the problem is located. Could be dual power, pto, or worn out pump. Manual show how to tap into the circuit at the pump. Assuming that the 3 pt lift is still working correctly when this happens. Would pressure test the high pressure side as well.
