I've owned a Parker tow behind sweeper since 1979. It works best if used after cutting the lawn when all the clippings and leaves are on the top surface of the lawn. When the brush is properly set, it works very well. However it is possible to go so fast as to allow the brush to sweep the stuff in the air so high it misses the basket. And as long as you are pulling it, it is sweeping, and that includes pea gravel driveways, mulched walkways, or any other area covered with loose material that you have to drive over. On the plus side, it will fit any current tractor you have and any future tractor you might get without any adapters or special brackets, as long as it has a std. single hole tow hitch on the rear. Another plus is that with just a single hitch pin, it is on/off, no tools required and less than 15 seconds. I use it every fall at my mom's home to sweep up the leaves and dump them curbside where the local municipal government collects them. Parker makes a very nice sweeper, but they are quite expensive new. I found a decent used 42" wide one last year for $10 (guy had no clue as to what it was worth, which was at LEAST $100), and I still have my old original one which still works fine. Having used a sweeper and a bagger, I personally prefer the sweeper as I can stay on the tractor during the entire operation, but as mentioned above I don't have to bag it to the curb as my local govt. vacuums it all up loose.
