I have an older style Accelerator grass catcher that I've used on my Exmark walk behind and Z-Rider for 15+ years. I did have to have the hinge repaired once, but they don't use that style hinge on the newer models. The new models are also compatible with an extension for leaves and other light debris. The quality of their products are top notch, as is their support. I don't know the capacity of mine, but it does fill up pretty quickly. If you're trying to pick up a lot of leaves with it you may be disappointed in how often you have to stop...same goes for any side catcher though. Much lighter than the steel models though and surprisingly durable for being aluminum.
