on the 4430 convert it from 2 6 volt batteries over to 12 volt batteries. on the 8440 get an electric destroking valve so when you go to start it the starter isn't trying to run the hydraulic system.
if it turns over that hard there could be a high pressure leak not allowing the pump to ever destroke.
