I have a BX25, 60" deck with the newer bagger system. Bought it used for about half the retail cost. I love it. Does a great job. If grass is wet you just have to slow down to allow for the heavier intake. As far as getting it on and off its a breeze once you learn how it was designed to be done. It's quite slick actually. Just back up to it, connect the drive shaft and turn the turn buckle to pull the bagger to the back of the tractor. No sweat at all. Even easier to remove. Highly recommend.
Exactly What was the model of your bagger for the BX25?
