    Ok not a problem with my tractor.
    I've jump started my tractor with my Ford explorer. But can I jump start my explorer with my truck? I have 4 batteries so is that 12volts or 24 volts?

    Depends what your truck is. Old ones ran four 6 volts in a series-parallel configuration (24 volt starting, 12 volt charging/accessories).

    If you just hook your jumper cables across a single 12 volt battery on your truck you'll be fine to jumpstart a car.
