I recently purchased an Accelerator grass catcher for one of my mid-size Toro walk behind mowers. As there is a lot of discussion about this product, I thought I would write a review on my experience with it, so far. There are several things I am impressed with: -The welds are top notch -The unit is surprisingly light weight -It fills well, and is reasonably easy to empty -It is not nearly as dusty as I thought it would be There are also several things I am very disappointed with: -The unit has had 3 days of use, and has a hole! (see pic2) Using the mesh on the bottom may save weight and increase air flow, but it is the obvious weak spot on the catcher. -The mechanism attaching the catcher to the mower is poorly designed. It falls off constantly, if the mower hits a bump, the catcher is gone. I have to bungee it to the mower. I am using this on a Toro SFS deck, and the rail on the deck isn't really long enough for the placement of the rear hook. If the rear "hook" was moved up to be closer to the pin, it would stay on much better. (see pic 1) -Finally, the pin that holds the latch shut gets stuck, I think this is because my latch has been welded on crooked, (see pic 3) On the whole, I would not recommend the unit, not for the price. I could have bought 2 factory replacement bags for the cost. If it had a solid bottom, and the mower attachment were re-designed, it would be a great product. pic 1- The catcher mounts to the mower by inserting the pin in a whole on the rail of the deck, then the hook at the back falls over the rail. Pic 2, the bottom of the catcher is mesh, I think mine must have hit a sprinkler head, or a curb or something The rear door latches with a simple pin, the design is good, but on mine the pin receiver is crooked, so it is pretty hard to get the pin in and out, I suppose I could hit the pin with the grinder.
