Strengths Ruggedly built, professional cut, great ergonomics, Kawasaki motor is smooth and reliable, will DEFINITELY cut your mowing time in half without having to go full speed, very fun machine to operate and makes mowing the lawn enjoyable, easy to change engine oil and filter, easy access to mowing deck belts, simple to wash the mowing deck with the quick hose connection.

Weaknesses Can be quite bumpy at higher speeds if your lawn is not smooth, takes 2-3 mowings to get comfortable with maneuvering around obstacles and getting use to sharp turns without scuffing the lawn.

Overall Absolutely LOVE this mower. I cut my mowing time from 1 hour 45 minutes down to 50 minutes without running the machine full speed. I hesitated to buy a zero turn mower but do not regret the decision one bit. If you are considering buying a zero turn, the Z445 is the better choice since it has the 25HP Kawasaki engine and 54 mowing deck. It takes 2-3 mowings to get used to the "feel" of the machine and get comfortable with the way it handles (totally different feel than a conventional mower), but once you have have it figured out, trust me, you will love it. I am totally satisfied with my purchase and highly recommend this machine.
