The Gravely ZT features the XLerator Deck technology available exclusively on all Gravely ZT Series Zero Turn Mowers is made with maximum airflow in mind helping to deliver an exceptional cut, backed with a 5 year Consumer Warranty. The deck is 5 inches deep helping to reduce blowout and maximize airflow. The Foot operated deck lift makes it easy to lift the deck on the fly to aviod yard debris such as stumps and has 7 cutting heights, which are adjustable in 1/2" increments from 1 1/2" to 4 1/2". A heavy duty polymer discharge chute provides a safe environment standing up to yard debris while allowing grass clippings to be evenly discharged. Inside the deck are tunneled cutting areas which help with grass lift and discharge.

Deck Lift and Belt Cover

The ZT comes with 3 deck widths; 34", 42" and 50". The 34" is a 2 blade deck with a blade tip speed of 17,500 feet per minute(FPM). Having 2 blades instead of 1 as many decks do in this width range helps reduce clumping, blowouts and bogging. The 2 smaller blades will spin faster than just 1 big blade will. The 42" and 50" width decks feature 3 cutting blades that have a blade tip speed of 17,000 feet per minute(FPM). The 3 blades improve overlap which reduces striping and random missed spots. This will help compete the mowing job faster while giving your lawn a well manicured look.

Gravely XLerator Deck
Click to Enlarge

The XLerator deck is made of 12 gauge stamped steel with 3 anti-scalp wheels. These decks are designed with 1" diameter steel spindles that have sealed bearings that are maintenance free. Most other residential zero turn's in this price range has aluminum spindles. This makes the ZT more durable than many of it's peers. This added durability gives you more piece of mind for the “just in case” incidents of running over large objects in the yard. Though stamped steel isn't as strong of fabricated decks, the Gravely XLerator deck's are deeper than other decks in this price range again helping with airflow and clipping discharge. Although the deck is stamped steel; for most homeowners situations these decks will last with proper care. But if you're looking for a fabricated deck, currently the Hustler Raptor 42-inch is the only one available under $3000. If this interests you then check out our review of the Hustler Raptor 42-inch here.

Deck Foot Lift Assist
Click to Enlarge

The deck is coated in rust resistant coating. Blade engagement is done via an electric Warner PTO and blades are driven by a belt. Pulley's and belts are covered on either side of the deck to keep debris from building up. The foot platform is not removable for access to rest of the deck drive belt pulley system. However the belts are accessable under the seat.

Deck Washout Port

The 34" model ZT comes with the Kohler 6000 series 660cc with 21hp. Both the 42" & 50" models come with a Kohler premium 7000 series V-Twin 725cc engine. The 42” model ZT has 22hp & 40.4ft-lbs tq The 50” model ZT comes with 24hp & 40.5ft-lbs tq. These engines provide consistent power and rpm's to power the decks keeping bogging to a minimum. Really in a residential cutting environment there should almost always be no task hard enough to cause bogging to begin with. But there is also exceptions to the “rule”. The 7000 series is constructed with cast-iron cylinder walls for additional strength and durability. Maintenance points are easily accessible. Kohler currently has a 2 & 3-year consumer warranties on the 6000 & 7000 series engines. Check out more information on Kohler's website.




One of the pitfalls of the zero turns in this price range is they use of duel EZT Hydro-Gear transaxles. We're not saying they are bad; In fact EZT's are the most common transaxles found in residential zero turn mowers under $5000. Remember though this is still a residential unit and is priced well under $5000 so you really can't expect it to have every bell and whistle. Perhaps this was a cheaper way to do it, but thats ok because keeping the cost down isn't a bad thing. Most Homeowners do not need top of the line everything for their respective cutting environment.


Hydro-Gear EZT's deliver great maneuverability and provide smooth controls. EZT's are sealed maintenance free drive units. Which means over time when gear fluid is over heated it will gum up and cause part failure. They're not designed for heavy loads and Gravely recommends a max hauling capacity of 300lbs. We usually don't recommend hauling more than 2-250lbs with the EZT. Haul stuff with your own discreation. This means that most any homeowner can pull a yard cart, a sweeper or use any other attachment that Gravely/Ariens has available for the ZT without worry. Learn more about zero turn transaxles here from our "What To Consider Before You Buy" article.




The Gravely ZT is equipped with traditional handle bar controls and driving the mower may require a bit of a learning curve for first time zero turn operator's. There are zero turn's equipped with steering wheels and perhaps one of these is a better option for you? Read our “Is a steering wheel controlled zero turn what I Need” article to help you decide. The control handle bars have a built in braking system. While the bars are swung out the parking brakes are engaged. When the bars are then swung back in the brakes are automatically disengaged. Handles are adjustable for many operator sizes and provide tight and smooth control with dampers for smoothier forward and reverse transistion. .



Gravely zero turn mowers tend to be some of the more comfort residential zero turns. The 34" ZT model has your average low back spring seat. But the 42" and 50" ZT's features a high back extra padded seat. Also the seat is adjustable in several inches front to back, but armrest's are not equipped standard but available as an attachment. The control bars are fully adjustable and have built in vibration isolators for smooth operation and added comfort. This adjustability allows most anyone to fit on the mower and operate it with ease. Contoured rubber foot mat isolate vibration for your feet and legs. This is a bit of a smaller unit when compared to commercial units so there is some added bounciness; But this is common on most residential units.

Adjustable Seat

When Gravely built the ZT model they had durability in mind for a entry level residential consumer with some commercial grade inspired design and features. Again one of the pitfalls with lower priced units we believe is the EZT Hydro-Gear transaxles. But really in this price range that is what you'll get. With proper maintenance and respect the Gravely ZT should last a awhile for almost any residential homeowner's cutting environment.

What Gravely ZT Owners are saying:


-" I have two complaints with my Gravely ZT XL 42"
#1# it cut the mowing time in half witch means I don't have as much fun
#2# the cup, drink holder is not deep enough "

-" I don't have a large yard yet cutting the grass is the last thing I want to do on a weekend or after work. This Gravely ZT 42 makes me want a bigger yard it's terrific. First driving it had a lot to be desired yet in no time I had no trouble maneuvering the mower. "

-" I have had my ZT 42 for 3 weeks and cut my 1 acre lawn several times. There are many obstacles, I had always used a push mower since a riding tractor really would not save much time. The ZT 42 has cut time by 65%!
It takes some getting used to, to not gouge the lawn, but you definitely will get to the point where you no longer are damaging the grass…no sudden stopping or transitions from forward to reverse on either control. Mechanical design and serviceability are great. One thing you will notice is that the frame definitely flexes on uneven ground. I assume this is not an issue on the heavier gauge ZT HD model which uses 10 gauge plate instead of 12 "

-" So glad I went with Gravely and purchased from my local dealer Capri Lawn in Naples Fl. I always bought from the box stores. Great to deal with people that have sold lawn equipment for 30 years. For a mower from the lower end of thre Gravely line this thing is solid. Hope to have for many years."

-" I'm loving the mower.
But I've been having trouble getting support from the local dealer; Bucheit's in Herculaneum MO. I tried to get them to order a mulch kit four weeks ago. They have still yet to get it in and have no idea when it will arrive.
Gravely's customer support site has been great. They told me the exact part number to order and I've bought it off the internet. The cup holder needs to be on the other side away from the grass discharge chute. The top of the can was covered with small grass clippings. "

-"I am a Professional commercial mower. I use Gravely on the job and decided to buy a ZT50 for my own lawn. Great cut, mower and product for the price!"

-" My first experience at owning a zero-turn. Had the advantage of barrowing the neighbors Toro Time Saver and seeing the performance of another neighbors monster John Deere. Went shopping at the local equipment store to learn more about Husqvarna. Shop owner listened to my experience and service needs for a mower – Pointed me to the Gravely. Very happy with the decision. Has reduced my mowing time by 70%. The triple blade deck leaves a very nice cut. Solid design and construction. "

-" My new zt34 runs great, but…..
It is too narrow, as a result
Lades don't extend past the wheels
Wont mow close to tree with out rubbing the wheel on the tree.
Wont mow under the shrubs
Wheels have to follow previous wheel tracks
Pay more and get 42 inch
OR get a bigger gate
Other than that, great machine! A real go getter. "
