Does any one run the Accelerator catcher? What is the cost and durability? Are the brackets strong? Is this catcher inteneded to bag grass or just leaves? I have been asking a very good employee for information about any variable about the job that makes it physicaly demanding. He stated several things one of which is that lifting the full grass gobblers with the extentions all day can add additional fatigue that might be avoided in some way. I was thinking that the all aluminum Accelerator has a far lighter empty weight when compared to the gobbler with its extention while empty. Any experinces or knowledge?
