Hello I am new to this forum but never the less i am interested in saving time. i would love some advice if u will on speeding up changing drum primarily in wirtgens. i have questions like what kind of carts do you use,do they have casters or wheels or just skids.do you leave the belt housing on the drum or install it after (only on a half lane 12ft is 2peice) how many of you change the belt tension. do any of you drain the water before removal. and as alwys we all love pictures. on my side of town we can swap a half with a full in about 5-6 hours with a 4man crew. i would love to hear some input from some of the other guys out thier who swap drums
