signed papers on 3016 today not delivered yet I am confused about operation of the PTO. manual says to depress clutch and move lever to engage position and than goes on to say to operate a push button that also turns. nothing like my 231 massey was. so once I do all of this can I operate PTO with the yellow knob/button using it to engage and disengage PTO without depressing clutch untill I am ready to shut it down and than depress clutch and move lever or what. I will not be here will they drop off my tractor. and believe it or not saleman didn't know he mainly sells RV's
