re: Help me decide on a great Zero-turn mower.

I owned two. A Grasshopper diesel and an Xmark. I liked them both. The Grasshopper was a beast. I put about a 1000 hours on it. No issues other than routine maintenance and one time the flywheel gear ring came loose. I misdiagnosed it as a starter issue. The shop discovered the loose ring, heated it and reinstalled it.

The Xmark was smaller and much more comfortable. I only put a 100 hours on it before I sold the place.

Given the two, I would go Xmark. Much cheaper and I didn’t need the commercial grade of the Grasshopper.
