Here is the TN retired redneck Seabee method of removing a Farmall H belly pump:
1. Place a hay bale length wise under the belly pump.
2. Place two 4 x 4s stacked on top of the hay bale and under the belly pump.
3. Slowly remove the four mounting bolts until the belly pump sits on the 4 x 4s.
5. Cut the bale strings and rock the belly pump until it is free of the tractor.
6. Slide the belly pump out from underneath the tractor
7. Clean up the hay bale and 4 x 4s.
