Gravely Pro turn 152 vs Toro Commercial Series 2000.

Hi this is Nick and Im new to the forum. Recently I've been looking at these two mowers to buy, they both would be a 52 inch deck with a Kawasaki motor. My dad and I cut lawns with a john deere tractor and we do landscaping jobs as a side job. Im going to college in the fall for landscaping, and I plan on expanding what I can cut with a zero turn mower. The gravely I can get from my mom's friend at a dealership for 7300. The Toro I can get a dealership for 6899. Im looking to get more lawn cutting jobs so I need something that cuts good wet and dry and can stripe the grass good. I just need something I can start with thats on the cheaper side, to just start off and later I would move up to a scag mower. Thanks for all your advice and recommendations in advance. If you have any pictures of these mowers cutting or the stripes I would greatly appreciate it. Thanks for all your input Nick.
