I recently bought a demo navigator from a dealer, it only had 10 hours on it so it was basically new. I've always ran the Lazer Z's with mulching kits or the ultra vac so I don't know much about them. I've had it for about 3 weeks and it has been at the shop more than it's been on my trailer. First, the door had a gap in it that was allowing leaves to blow out. Then the alarm was messing up and wouldn't come on when the container was full. Now i'm having a problem with leaves coming out of the vent on the back of the door. I asked my dealer about it and they said it was doing it because we haven't had a lot of rain lately and the leaves were so dry. Is it suppose to be doing this? It's not throwing every leaf out the back but it's throwing enough so that I have to run over the same spot twice and in some areas 3 times in order to get all of the leaves out of the yard. This is the first navigator that I've owned and when I purchased it I was thinking I was getting the best vacuuming mower that exmark offered. But, after using it on a few yards it doesn't hold a candle to the job the LazerZ with the bagging system on it does.
