I have to say that my favorite implement is what ever keeps me from having to do the current task by hand. SO if I am putting up fence, it would be the PHD, moving dirt- the box blade although the FEL plays a larger roll in that also. If I am preparing a garden spot then it is the 8' disk followed by the cultivator for making the rows and keeping down the grass as the garden grows or my 6' shredder for mowing the pasture. So I would have to say that if any of them was to leave my possession for any reason, it would have to be replaced. Picking a favorite implement is as difficult as picking a favorite child, I dont think anyone would want to be without any of them. But unlike kids, most of us can finally have enough kids, but we can never get enough toys, uhhh, I mean implements.
