I have no idea what they mean by a 6 degree turning radius. The description is nonsense if you think about a turning circle and it's radius. What you really need to know is how many feet you have to travel forward to perform a complete turn or the turning radius. The length of the radius from a dead stop required to complete a 360 degree turn (a circle).

I'm no mechanic but sounds like the starter isn't engaging, Does it have a solenoid? If so you should be able to bypass it, Can you turn the key to the on position and jump start it at the starter? Are you sure the motor isn't locked up, check the oil, Hope some of these suggestions help.

Jim, please post the model number and serial number of your mower. Also please post the engine model number and other numbers from the engine itself. Your problem might be caused by something in the tractor chassis wiring, or it could be specific to the engine you have. Without some identifying numbers, we can't check our sources for info on anything. Also, let's be perfectly clear on what you mean when you use the word "crank". Do you mean you turn the key and absolutely nothing happens? No noise, engine does not spin? Or do you mean the engine spins but it will not catch on and run by itself?

I agree with ptg, You don't have enough property to justify the need for a Zed. Keep a few things in mind here. ZTR's were developed for people in the BUSINESS of cutting grass because time is money to them. Zed's are expensive to buy because, unlike a lawn/garden tractor, they have TWO hydro pumps and TWO drive motors. For Joe Consumer, that's twice as many things to maintain, to go wrong, to repair and to replace. A LT/YT/GT is far more useful than most Zed's are when it comes to doing other chores around the property. The exception here is definitely the Walker but the price speaks for itself. Aside from ground speed offered by Zed's, the other bonus is their ability to manuveor around objects, obstructions etc much easier and quicker than a conventional tractor that has a belly mower. An all-wheel steer (as suggested) will help you greatly when mowing around tree trunks, alongside twisty garden beds and sidewalks as well as other tight areas. If you said you had three to five acres of actual lawn to mow, then I would agree that a Zed should be considered. Especially if the property was well-tree'd or had extensive plantings, the abilities of the Zed would definitely save you time. However, my advice would also echo ptg's regarding your budget because a property of that size would dictate buying a true commercial quality unit. It's better to buy a decent quality garden tractor than a low-end ZTR.
