I just bought a new 48" Bob-cat walk behind with the ergonomic z-control feature. I set the deck height as the manual says and it just doesn't stripe. My employee has a 10 year old belt drive Bob-cat that stripes like no other. When I bought mine, part of the reason to go Bob-cat was because of the phenomenal striping I've seen. Has anyone else had the same problem? Have you been able to get your "extreme discharge" deck to stripe?
