I have a Exmark Lazer HP (52" w/ 23 HP Kawasaki.) I am interested in towing some things (plug aerator, utility cart, spreader etc) but the hitch has a warning label that says not to tow anything over 80 lbs as it may damage the hydros. This doesnt make much sense to me given that it is a hydraulic transmission, which by definition is supposed to be heavy-duty.. Does anyone have thougts/comments/experience on towing with one of these? Thanks!
