Yes under a load the blades slow down. This is what I have done so far.sharpened the blades, replaced all belts, checked the spindells, have taken off the pto, It engages and the blades spin fine with no load on the blades, Also have adjusted the gonernor to give it more power. Is it possible that the pto is slipping under a load
Thanks in advance
