looking at a Lesco 52" ZTR with front deck; power to blades via PTO/solid shaft, which I guess is common for out-fronts. I've seen previous mention that blade speed is less than machines with power supplied via belt. But I also recall seeing an ad once, with the manufacturer touting high blade tip speed for his out-front. I'm confused. Does anyone have information or hard facts on this subject? For the type of accounts I have, quality of cut is important. Thanks.
