I think you need to provide more information about how you intend to use it before anyone can give you a reasonable answer. Do you want a tiller for the garden? What will you be lifting/moving with the Front End Loader? How high do you need to lift it? For example, will you be lifting it high enough to clear the sides of a dump truck, or something similar? How deep do you need to be able to dig with the backhoe?
Same as others. Please give us some more info on the uses of the tractor and we'll be sure to help. Just a guessing game without knowing what you need to do.
