I like my Kubota Bx GCK60-23BX grass catcher. Its powerful but compact. Goes on easy enough. You roll it on to 2 hooks at the bottom, tilt up, put drive shaft on the PTO and put in the 2 top pins. It gets in tight places. Turns on a dime. My neighbor has a DR tow behind on his JD 240 mower and it sucks up leaves good and holds alot. However it's long and You need alot of room to turn. Backing up with it, he broke the flange where it mounts to the tractor and had to weld it and reinforce it. The DR chops leaves up finer. Both units can clog up from sticks. I have You tube videos on sucking up the leaves with the Kubota grass catcher under the name of Paul Sargent. add Kubota to the search and you'll find it. I'd put a link but I'm new to forums and don't know if it's OK.
