Exmark, I am very dissatisfied with the baging systems you have for the exmark lazer z hp's Ultra Vac! Good idea, and works very well, but the quality is terible!!! I love my mower and it has only 180hrs on it, but the ultra vac is crap!!! Here are the things that are wrong with it: 1. The bearings are warn out in the fan 2. The bags on the back are warn out and are falling off the metal bracket 3. The inside of the vaccum is warn out (Fan) 4. The shoot on the side of the vaccum has a 1/8 inch hole on it I had to have my machanic weld a peice of steel on the inside of the vaccum to keep it from wearing a hole through the side of the shoot. (that is working). I told my dealer and they said that they would replace the shoot, but not the bags. They also told me that I need to put on a mid sail blade on the side of the bager, to keep the dust from going into the vaccum. I said to them, why didn't you tell me this in the first place, and better yet, why do the mowers come with high lifts on them when they knew I was going to be baging. I would like an answer and would like to see something done about this. Another dealer, said that they would try to see what they could do for me, and I didn't even purchase it from them!!! My hope is that you can replace the vaccum and the bags, so I won't need to when the warranty is up!!! We all need to remember these two words in life, CUSTOMER SERVICE!!!
