I bought a Z about two years ago, before the remote air filter was standard, and added a BacVac shortly after. I am currently at a crossroads, either I will switch brands or I need an acceptable solution. As far as the BacVac itself, from day one I've had a gap at the top of the clamshell which allows vast quantities of dust and dirt to blow forward into the operator's neck, I believe this to be the result of a bent hinge, but can't seem to remove the hinge to straighten it. I'm looking into a gasket that would seal this gap from the outside. The side walls of the clam shell are caving. the factory rep suggested that this was the result of driving with the bagger open. Needless to say that is bunk! With tha latch down the hooks are pulling against the pins and pushing the sides in. I tried reinforcing the sides with 1/2" angle, but it doesn't work. Any suggestions? I believe the entire unit has too many small parts (e.g. the system holding the bagger on consists of eight different (loose) parts). I have changed this to two pins with two clips which are all attache d to the bagger so I won't have to worry about losing them. I'd like to get rid of the idler pulley, chain and spring on the blower unit, use a shorter belt and tension it by latching the blower into place. Can this be done? I'm looking at attaching "T-handles" on the hose clamps unless Hustler has since come out with a quick connect?? I am very concerned about the entire mounting bracket, it is my contention that the bracket causes heat build up in the engine area and should be redesigned/modified by cutting holes / slits in it. I am at a loss about how much material can be removed without losing structural integrity. Since I've put the bagger on I've had the following problems with the mower (hustler does not seem to want to accept I may have a valid issue). Shortly after installing the vac, my airfilter clogged, a new filter only lasted five hours! Poor airflow with the vac attached!? Thanks to the dealer Hustler agreed to pay for the remote air filter which by then was standard on the new units. The right wheel drive started lagging. The dealer confirmed the unit was sluggish and not performing to spec. they contributed it to the unit sucking false air. Just in case I paid for a transmission fluid change (the mower was less then a year old and had less then 250hrs on it). I turned the elbow horizontal on the outflow so that any air or foaming would not just go to the right wheel. the outcome of that was that I needed a trans cooler Hustler paid for the cooler, I paid for labor. Now I've been down for two weeks, the engine is skipping and the electrode on the rear plug is being bent by something. Hustler tells me i need to de-carb the engine (The first one in fifteen years, ?????), a minimum of $300. Don't get me wrong, I like my Z, but from my a-technical point of view, the bac vac caused heat build up, which in turn caused transmission problems and possible engine damage. Did I just get a bad apple or am I going to get the same problems if I upgrade (and transfer my vac) to a super Z or Super mini. I've been looking at the wright stander, the Toro, the tiger cub or replacing this one with a Hustler. Any thoughts??
