This is just an open ended question. One of the improvements of the new Lazer Z was loosing the chains that support the deck (plus a stabilizer bar). I can see some advantages (seemingly small) but really knever new there was a problem to be fixed. Are chains that bad, I never heard of anyone complaining. Everyone should know by now I'm not an Exmark basher (unless it's a Triton that needs bashing). Tell me the benefits you see using the metal rods instead of a chain and maybe why a chain that is time tested may be better. Just as the drive shaft on the Scag's I run are supposed to be an improvement even though they are belt driven, I don't get that either really. I'm all ears. If you hit and obstruction doesn't the chain allow the deck to move and not take the full impact (or the object you hit). Maybe it is an improvement but since I haven't seen it up close it's hard to say. Comments?
