Rated 5 out of 5 by Love my Gravely Cut my mowing time from 4 hours to 1 hour. Took some getting use to the zero turn but great machine June 8, 2012
Rated 5 out of 5 by Excellent Mower!!! I have used several other ZTR mowers in the past and this is by far the best yet. It is very durable and a pleasure to use. I would definitely recommend this mower to anyone who is considering a zero turn. I did buy the optional rear engine guard...which should of been included.... and it definitely enhances and protects the rear of the mower. I would also recommend adding the hitch for pulling a small dump trailer. June 8, 2012
Rated 5 out of 5 by Great mower!!! The ZT XL fits my needs perfectly. Over the last year, it's been a pleasure to cut my grass with. I've had no problems with it and it will flat cut some grass with plenty of power in reserve. I love the flip up floor and seat design to make cleaning it a breeze. You will not regret buying this mower, or any Gravely for that matter. June 8, 2012
Rated 5 out of 5 by One of the Best Buys That We Have Made We mow 2 1/2 acres on our horse farm around several buildings and a tree-lined driveway. The ZT XL has more than enough power for all of this and has no trouble with high grass in an unusually wet and cool spring. Bottom line: compared to our 8 year old John Deere garden tractor (a fine, tough product in its own right which is why we keep it), we now mow in 1/2 the time; use 40% less gas; and are far less tired as the seat is much more comfortable. The zero turn feature is critical to saving time and effort previously spent hauling on the steering wheel to get around trees and corners, which is a big deal when you have a good many things to mow around. The ZT XL always starts with no problem. It has a large fuel tank mouth that eliminates spills when fueling from a 5 gallon can. The grass cuts more evenly and the wide range of cutting heights possible is a great plus for us. Noise is no worse than the Deere. Takes a little bit to learn to handle the sensitivity of zero turn when it is coupled with high power, but it becomes real instinctive when you do and so well worth it. The XL is powerful and the speed feels insanely illegal when let loose on a large, open stretch of lawn. Our ownly regret: we should have bought one years ago. I know that it another piece of equiment to have around, but large land owners need an XL for reasons of economy, speed, comfort, and ease of use. June 8, 2012
Rated 5 out of 5 48" XL just what I was looking for. I previously was mowing my 1.5 acre yard with a 38inch tractor and we also cut our neighbor's 1.5 acre yard for cash. Both yards would typically take about 4 hours to mow.I looked at literally every zero turn mower available comparing features and price but keep coming back to the Gravely brand on value and features.I chose an 48" ZTXL because I liked the heavier frame materials and fabricated deck.The XL cuts great, is easy to drive and cut my mowing time from 4 hrs to just under 2 hrs, bathroom breaks included! June 7, 2012
Rated 5 out of 5 by This product has all the features that I needed with the durability I wanted I spent the extra money for the ZT60 XL to get the durability that I wanted without getting into a higher end commercial mower. If you check out other brands you will see that you get a little more with the Gravely lines. I also wanted a mower that will last me 20yrs which I feel I can get out of my Gravely. June 7, 2012
Rated 5 out of 5 by The best mower I have ever own. Over the years I have owned several different mowers and after a few mowing seasons I would have to do some costly repairs and since I have owned my gravely zero turn mower I have not had to do any repairs. The mower is very well built and has cut my mowing time tremendously. I would definitely recommend this product to a friend. February 27, 2012
Rated 5 out of 5 by Great Mower I just bought my mower last week and already love it, cut my mow time in half. March 25, 2015
Rated 1 out of 5 by poor This mower mowes fine it just that it gets you filty dirty when mowing.I would not recommend this mower to anyone.Gravely people say there is nothing they can do to fix it.I have hade three other zero turn mowers and they did not get you filty dirty. August 1, 2014
Rated 5 out of 5 by Top notch mower with only minor flaws. This was my first zero turn and I have been very impressed. I have ran multiple brands (Exmark, SCAG, John Deere and Husqvarna) and Gravely just completely blows away the competition.This mower performs well worth the price tag. The deck is pretty much invincible, the cut is fantastic, and the controls are incomparable to any other mower on the market. However, I do wish that it sat a little higher. It handles on hills very well, but if you mow over thin grass, you will be filthy from all of the dirt that comes out the front of the deck. It is also very rough riding.But overall, there is a reason I gave this mower an almost perfect rating. Tough, reliable mower with local and friendly service. Gravely is the best there is, and I look forward to purchasing a commercial series for my business next year. July 22, 2014
