well guys went out last week and started up the zrt to get up some leaves and broke a rod in the 30hp kawasaki. mower had 4096 hrs on it. weighed my options and the block is cracked and i cant afford to replace the whole engine right now so the guy at the local dealer bought it off of me for $1,500.00. so i went out and bought a 52'' w/17hp kawasaki, bobcat walk behind.guy just replaced drive belts, all the fluids, plug, has a brand new set of gator blades and regular blades with it. comes with a sulkie also. has 870 hrs on it.
