Net HP is usable "flywheel" power with the engine installed in the vehicle. Gross Power is sometimes called "bare engine" power. It is often (but not always) the number used in advertising since it is the highest. The test results can be reported with the engine producing "intermittent" power or "continuous" power. Continuous rating is usually about 80% of intermittent. Continuous would be most meaningful for applications like generators. Most tractor applications only require intermittent power. PTO HP is what would be measured by a dynamometer attached to the PTO of the tractor so it reflects power train losses. PTO HP is approximately 85% of Net HP for many tractors. It will be slightly lower with hydrostatic drive due to the power consumed by the pump even with the tractor not moving.
As an example, at the rated engine speed of 3200 RPM, the JD 955 has 35.3 GROSS HP, 33 NET HP, and 27 PTO HP (hydrostatic).
Even though "power is power," when comparing specs of different tractors you have to be careful to use the same basis--gross, net, PTO, intermittent, continuous, etc. The problem is that sometimes the basis of the test is not provided in the information you have available.
I hope this isn't more than you wanted to know. ">  Tractor Horsepower
