While we were at the Gravely dealer picking up our 34Z for gated yards I was looking at all the bigger models. Man was i impressed with the way these machines were built. They looked like you could drop a bomb on them and they would come out fine. Massive frames, massive front forks, massive front tires. EVERYTHING was MASSIVE. Next year I WILL be getting a new 152Z and getting rid of or keeping our 48' lazer hp as a back up mower.
