I apologize for my first post being a HELP question, but here goes: My folks are in Tennessee and I'm in Florida, so I'm a bit restricted how I can help from here. I was there two weeks ago and replaced the battery in their RZ3016. Mower worked fine before that, but now starts just fine but doesn't move when you move the control levers. When I removed the battery I took out the left bolt holding the seat and the two top bolts on that forward metal plate that was blocking the battery in. Sorry, I don't have a photo. I unplugged the right side control lever during the install, but of course plugged it back in and have double checked it. Everything is buttoned up as it should, but it simply doesn't work right. Any ideas? Thanks, guys.
