Defender1

I have to introduce me as well her as I am new to this forum, and new to the Lego world as I have not tought lego in the last 25+ years. I have ordered the 8110 box to start hopefully in a fue day from now. I must have some old lego but that is not workingvery well any more due to old and not strong anymore. I am wondering why no knowboddie has build a three point linkage behind and up front on the MOG? to attach all machines to it like in the agri world?
