Rated 4.8 out of 5 by 147reviewers.
Rated 5 out of 5 by Best Machine I have ever owned I purchased the ZT HD60 two years ago. Best investment ever! I have a 700 series John Deere as well, and the JD does not compare to the mowing abilities with the Gravely. Our yard is about 5 acres and time is important to me. Wasting time mowing is not one of them with the Gravely. It is durable, reliable, fast and strong. It costs more than other brands but WELL worth the price. I hope The Gravely Company continues producing high quality products, if they do, they have a life time customer.LTK June 13, 2012
Rated 5 out of 5 by Great Mower Have only had mower for a short time but has made mowing not a chore anymore, went from a 48” lawn tractor to a 60” ZTHD and cut my time in more than half to cut my 3 acre lot. Well worth the $$ still asking why I waited so long to buy one. June 12, 2012
Rated 5 out of 5 by Excellent Machine The ZT HD 52 that I have is a wonderful machine. It has all of the features and durability of a commerical machine, but not the price tag. The unit is rugged and very well built. I would not hesitate to recommend this product to anyone. If you have alot of grass, and you are looking for a excellent machine, with great value, look no further than the ZT HD series. Great Job Gravely!! June 11, 2012
Rated 5 out of 5 by great machine I have had my 52" cut zero turn Gravery for almost a year now and it is the best purchase I have ever made for a good mower. I also have a zero turn Snapper and I don't know if it is the horse power differents or not but the Gravery is much faster and cuts so much beeter in tall grass. I would recommend the Gravery to anyone who wants a great cutting machine. June 9, 2012
Rated 5 out of 5 by great mower, very good value I'm riding my second gravely (moved up to a larger model) I was and am very happy with both machines. great power and a smooth cut in tall wet grass, a well built mower. June 8, 2012
Rated 5 out of 5 by GREAT mower I got the Gravely 48HD and it is the best mower I have ever had. The mower cuts great and the controls are simple to operate. It also has a great amount of power and it is worth the money you pay for it. Overall it is a GREAT mower. June 7, 2012
Rated 5 out of 5 by What a machine I dont know why I waited until I was 65 yrs old to get a Zero turn.After a long research process, I feel I got the best machine ,for the money , on the market. This Gravely HD60 is built like a tank, and man can it cut grass. It is also very easy on fuel, with the Kawasaki motor. I guess its no different from any Zero Turn , when it comes to steep hills, as it goes up them without a problem, but going down hill is a problem. I really am impressed with this machine. It will probably be the last mowerI ever buy. June 7, 2012
Rated 5 out of 5 by My ZT60HD is the best mower I have ever used. I mow 4.5 tree covered acres. It used to take me 8 hours with my 60" deck hydrostat tractor. I am now at 2.5 hours and it will get faster as I become more proficient as an operator!! I love this mower and would recommend it to anyone. Also, when I was looking at the mower I was warned that it wouldn't be great on side hills. I only mow 4 sidehills but it handles them better than the New Holland TC24DA that it replaced as the mower! Much less prone to tipping and no problem to control. June 7, 2012
Rated 5 out of 5 by Great mower for the money. I looked at several different mowers before I bought the Gravely HD. I have use exmarks and Hustler comercial mowers and the Gravely hangs with the best of them. The cut is second to none and so is the quality. The Kawisaki engine it has is one of the best on the market. You can tell as soon as you turn in on this is a quality unit. It cut my mowing time down by a third and now allows me more time for other things....Like fishing. Only thing I am upset obout is that I didn't buy one sooner. Don't waste time wondering if it is worth the money because it is. June 7, 2012
Rated 5 out of 5 by Buy your last machine 1st! I don't know why I waited so long to get my life back. I'm on my 2nd season with my gravely and I would get rid of a lot of other things but not my machine.It has cut my cutting time to 1 hour instead of 3 which gives me time to play more golf.The machine is built to last!Do yourself a favor and buy your last machine 1st.In New york go to Sherwood power eq. for the best deals around.

Why Zero-turn?



You can cut your mowing time in half using a zero turn mower instead of a traditional riding lawn tractor. Here are some of the time-saving features of zero turn technology:

Maneuver Around Obstacles

The maneuverability of zero turn mowers allows you to easily mow around trees, flower beds and other obstacles in your yard more easily than with a steering wheel vehicle such as a riding lawn tractor.

Drive at a Faster Speed

Zero turn mowers are designed to cut grass nearly twice as fast as traditional lawn tractors so your straight line mowing speed is improved. A typical lawn tractor cuts at a speed of 3-4 mph while a typical zero turn mower cuts at a speed of 5-8 mph.

Mow in a Single Pass

When you get to the end of your yard and have to turn around and come back, you literally can spin 180 degrees and come straight back without having to back up and cut the strips of grass you would miss when making the turn with a lawn tractor.

Eliminate Follow-Up Trimming

With an unobstructed view of the cutting deck, zero turn mowers make it easy to cut very close to your trim edges – you can nearly eliminate the need to trim hard-to-reach areas with a push mower or a string trimmer after you've finished mowing.​​


Without a steering wheel, a zero turn machine may look intimidating to drive but most people become comfortable with the way it handles after just a few times mowing their lawn.

Steering a zero turn mower is easy. In fact, it is not that different from steering a shopping cart.

  • How to make left turn with Zero Turn
  • How to make right turn with Zero Turn

  • Forward: Push the handles forward.
  • Reverse: Pull the handles back.
  • Right Turn: Push the left handle forward.
  • Left Turn: Push the right handle forward.
  • Stop: Bring the handles back to neutral.

The key to driving in a straight line is to assure that the same amount of pressure is applied to each lever.​​
