It was a bit confusing wondering which brand of chute blocker to buy. It seems like the manual models seem more popular but I took a chance on the Power Chute for my Scag since it gets more use. After watching the video on the website I just liked the way it was designed, the fact it will rotate 180 degrees in increments, I don't have to take my hands off the bars, and it doesn't stick up very much (no handle to get caught on something). Is it the best one? I don't know since it's the only one I have used but it works very well. It's amazing how fast that little motor will open and close the chute. If I have any complaint at all it is that it is so fast It's taking me a while to get used to stopping it at the right spot if I want it partially up or down. I'm not saying that it's the best out there but I would buy it again. I should have gotten one a long time ago. One thrown rock and it will more than pay for it's self. I feel much more confident when I'm near auto's, mulch beds, or pointed a anything I don't want damaged or throw grass on. I don't care which brand you get but I would recommend getting one for anyone in this business. I don't know what I was thinking all these years.
