Yikes don't do that!
he was asking a rhetorical question.
Deadheading a pump will either fracture the pump housing strip a drive tang/gear or possibly blow a hose. Or if you are really luck the system has a relief built into the system to relieve pressure before a catastrophic failure.
If no funny noises or other odd things happened when you fired up the tractor the first time I would suspect a vacuum leak on the suction side
of the pump.
Until there is fluid in the pump it wont do a whole lot of anything.
A vacuum leak on the suction side will cause the pump to just pump a small amount of air from the leak and it will not be able to pull the oil up into the pump itself. If you can check the draw side for leaks I would start there. You might be able to open the output connection past the pump and then back fill the pump, start it till it spews oil and then reconnect the pump output connection.
Of course if the pump is at ambient pressure (pump submerged) then these suggestions are probably not any help.
