I have used this bagger on our riding mower for about four years, and it has given average results. It usually gets the job done, but it does sometimes have trouble filling up both buckets with grass. I would rather if it was more effective at actually holding grass. Performance This bagger works pretty well, although it sometimes has trouble getting the grass to feed into both buckets. Sometimes one bucket will fill up well, but then it makes the mower just spit out grass instead of sucking it into the other bucket. Handling These baggers are a little bulky, especially for trying to mow in the corners of a fence. But they are better than the bagger with three buckets, and I can usually back into the corner and get most of the grass (the bagger pushing the chain link fence a little bit). Durability The buckets themselves are quite strong. Even with occasionally bumping into fences and trees, they have withstood some abuse without any cracks or breaks.
