I was in a pinch to replace my 8 yr old 48" cut rider that I sold. Look at several other brands and found this to have the smoothest transmission. Like the other review, my only complaint is the traction in reverse. I think it is do to low end torque because of awesome Kawasaki 22 hp engine. I have been told these soft tires are designed not to tear your lawn when they spin, and they don't. This is the only reason why I gave the design a 4/5. From what I have heard, Kawasaki is the best engine out there and the 22 hp is more than enough. The competition at equivalent price was a 20 HP Kawasaki. I am 6'4 and fit well behind the controls. Others I had trouble with the control arms hitting my legs. I also liked the low center of gravity on this unit compared to all others. Hill sides were not a challenge as I have heard with ZT mowers.

I was concerned about cutting time by going to a 42", but it took me 1 hr exactly when my 48" rider with 21.5 hp took me 1.5 hrs on an acre. This was also just the first time I used the mower. I'm sure I'll get better as I get used to the controls.

I encourage you to refrain from buying any lawn mower from a big box store. Customer service with an independent dealer is much better, and you have the confidence the unit was set up correclty the first time.

Generally, a positive overall impression of the ZT42. I use it this ZT42 for 1 acre lawn for up to 25 mowings per year (i.e. less than 25 hours of service per year). Gas tank on the smaller size (2 gallons) leads to frequent refills. Also, disappointed with the durability and quality of construction due to broken frame weld on the front support bar. Potentially a design issue or manufacturing quality issue.

Comments about Gravely ZT 42 Zero Turn Mower:

Use the ZT 42 residential on 1.5 acres of flat grass mowing. Unfortunately after 3 years, the frame welds snapped and the mowing deck dropped off - so glad no one was hurt. Gravely (Ariensco) reply to the engineering design flaw is "sorry" . The fix is on you - not our fault.

    Comments about Gravely ZT 42 Zero Turn Mower:

    I've been at my home approximately 13 years. I've gone through 3 different mowers. One cub cadet zero turn(1980's model), one toro, and one husky. My yard was plagued with groundhogs and moles, so suffice too say, rough ground in most of my areas. Also, some heavy brush due to overgrowth from heavy rain and absence for work. I was using a self propelled 8.5 hp John Deere and it worked very well. I have .54 acre's with some 30 degree hills. It would take me roughly 2hours and 20 minutes to cut the grass and to some touch ups. I had been cutting with the push mower for 4 years after all of the riding mowers had broken from the rough terrain. Extremely exhausting. Did not look forward to yard maintenance what-so-ever.

    I'm a mechanic by trade. Not a issue to repair a riding mower on any given weekend. I've had issues with them breaking due to the ground being uneven. I was recommended to gravely by my father, since he had purchased one, and told me that it is a very tough machine. Not disappointed whatsoever. Went from taking 2-1/2 hours to 28 minutes to cut the grass. Love this machine.

      I have around 500 hours on mower and the front caster mount broke off machine the frame is very poorly built. I really like the way it mows but the quality of frame is very poor. I am shocked at how poorly this was built. I had extra supports welded to bottom because of the way it was built. I had it fixed because how much I like the way it mows and I already bought it. Unfortunately I will not buy another Gravely machine.

                I had to have a machine that fit my yard and three gates. The ZT 34 worked just fine. I had checked on several other models but came back to this one for what it did for me. I did not have to move gate post or build bigger gates. Mowing time down 50%. Learning to drive was really fun and I look forward to mowing . A strong well built machine.Highpockets

                Love it but wish for a rear discharge like the old Wheel Horse mower. That way you could edge from both sides. Could use the Gater blades for mulching which are not available for the ZT 34. Discontinued the 16.5 hp Briggs and Stratton intek which they should have kept and which I have on mine. I'm a

I will be contacting dealer asking for a refund. please try out before u buy. Won't start with turn of key you have to choke it. Crazy for being brand new. Also has no traction.

                        Comments about Gravely ZT 34 Zero Turn Mower:

                        This was my first new mower purchase and my first Gravely. My acre and a half yard is uneven with both rises and ruts. It's a rough cut but the Gravely does a fine job. I have had it for three years and other than PM all I have had to do is replace the blades. It cranks every time and cuts no matter how high the grass gets. My neighbors, having seen the performance of my Gravely, have made the decision to purchase their own when they replace their current mowers.
