I bought a 34 inch Gravely ZTR the 1534 model. It came with the regular bagger kit, and I have been unimpessed with how it bags. It seems to always get clogged in the tube, like it cant push the grass up the tube. Anyways the dealer says theirs an optional attachment availabe that installs between the deck and the bagger tube that is basically a big fan that sucks the grass up the tube. Does anyone here have one of these? How well does it work. Also how long does it take to install or take off if you wanted to switch to side discharge vs bagging. Also lots of the yards I do only have a 36 inch gate so I have to drive the mower thru then attach the bagger kit, witch is why being able to take it off and put it back on is important to be quick and easy. Thanks for any input.
