Tiedeman,
If you are having trouble with deck tilt there are a couple of things you can do to minimize it. One clever way is to weld or attach a nut to the left deck support (I am assuming you have a floating deck mower), with a long screw that touches the top of the mower deck. This prevents the opposite side of the deck from rising if the catcher weight pulls it down on the other side. When you are not using the catcher, just back out the screw a bit for a full float on the deck. Deck tilt seems to be quite variable between users. We have some people who use our jumbo on 36 inch mowers and have no problem at all. I think it has to do with deck weight as well as how the geometry of the deck suspension is worked out. If the suspension arms are towards the edge, it is harder to tilt up the other side. If the deck arms are more towards the center, it tilts more. At any rate, if anyone has a problem with our catchers, we will do our best to help out with a solution.
