Hi, I just made the jump to a commercial grade mower to manage my rental properties. (I don't have a commercial lc business). I just purchased a 2000, Toro 44", floating deck, T-bar control mower with a 15hp Kohler engine. Seller indicates only 100 hours on the engine. Seller is including Jungle Wheels and 2 sets of mulching blades. I am inspecting and picking up the unit next week. I have two questions: 1. What should I look for when picking it up to reduce the chances I bought someone else's headache, and 2. What are the first things I should do to the until once I have it home (maintenance, etc...). Any help or advice is appreciated.
