Hi Brettly, Neither my 22" or 20" Rover Procuts handle catching long grass very well. The long leafy grass like paspalum, Kikuyu, Love grass is the worst. Seems to have trouble getting the long leaves through the chute. It handles overgrown couch much better. Even though the volume of clippings off long couch is greater, because they are shorter pieces, they seem to travel through the chute better. (if that makes sense)
My self drive on the 560 packed it in today. Started jumping on the ring gear in the wheels and eventually, I think the roll pin in the chain cog on the axle dropped out. New wheels, drive pinions and pawls on order.
