Those shields you have missing are part of a kit installed to prevent heat in the engine compartment. Some times the heat is enough for fires to easily start. Those parts are not available through deutz as they are parts gleaner designed and put on for their application. I would prefer they were there if it were my machine. the other ting that would concern me is that there were several other mods done at the same time and they were also important to life of enigne and other componants and to the prevention of fires. Give Bruce a call at 580-832-3396, he should be able to help. shoot me an e-mail if i can help........thanks vstk
