Commercial 21 X-Series

It’s revved up and means business.
There’s tough. Then there’s this—the Commercial 21 X-Series—with its front engine guard designed to protect the valve cover and other vital parts from trailer damage. And its formed, steel wear plates on the cutting deck edges to guard against the abrasion wear that comes with the job. If you’re looking for performance and durability in a commercial-grade trim mower, get yourself a Commercial 21 X-Series.

Back in the spring of 2015 I made the transition from the Exmark Commercial 30 to the Commercial 21 X-Series and I couldn't be happier. Long story short, with my yard, everything the 30 struggled to do the 21 has done with ease. I have a half acre yard with many terrain features, trees, fencing, shade, and one very steep bank. In my shady lawn there is almost never dry grass. Rain and high humidity keep the grass moist to wet a lot of the time. The under powered 30 would clog every time I used it whether I was mulching, bagging, or even side discharging. While the wider cut made cutting seem quicker, I lost more time cleaning the deck than I saved with the wider cut.
The 21" deck is aerodynamically designed better and results in a better cut, no clogging (even when mulching), and the net result is I'm spending the SAME amount of time cutting my yard as I did with the 30. Because the engine never bogs down, I can travel across the yard faster. And without having to stop to clear grass from the deck there is less time wasted. The 21" is far more maneuverable, powers up the steepest inclines with ease, and side cutting the steep bank out front is a breeze. I've used both the black "gator" blade and the red mulching blade both bagging and mulching. I don't like to bag, period, but I'll admit the finished cut is slightly better when bagging but very acceptable to me when mulching. The red mulching blade goes through even wet tall grass easily. It has 6 cutting surfaces with 2 at the cutting height, 2 diagonal surfaces, and 2 up next to the center where it attaches to the spindle. Unless you get careless and hit large rocks or debris you should only have to sharpen the bottom pair. The black blade has a wider cutting surface and will allow faster travel across ground while bagging without skipping grass. The red blade will mulch a wet thick layer of leaves easily, leaving fine brown particles in the yard. For me, the red blade under the Commercial 21" works best.

I have a 2014 Toro commercial that is an incredible mulcher but is not the best handling mower. It was my hope that buying the 2014 Exmark that I would get the best of both Worlds. I based this on both are the same company.
If you are bagging or cutting warm season grass you cannot go wrong. For me I will have to take a financial loss and sell my Exmark because 100% of my lawns I mulch and purchase another Toro.
My dream 21" mower is the cut quality of a Toro and the handling of an Exmark!

            Mower works great is you bag. Mulching is not very good. Also, engine has always been hard to start when cold. Main shaft seal failed, lost oil when mowing. Luckily the engine survived even though it overheated and ran out of oil. Happened just out of the warranty period. I now check the oil at each use. Still a great machine, I have recommended to others.

              I own a small Landscape company in southern CA and I love this machine, Best Cut in its class. I have own this mower for over five years and it is still going strong, and I love that the tires are heavy duty and I don't have to keep replacing them. I also own a thirty inch Exmark and it literally cut work in half. I would recommend this mower. I am in the process of buying another Exmark 21 inch mower and a Exmark riding mower as my business continuous to grow. Go ahead and buy with confidence!

              Comments about Exmark Commercial 21 X-Series:

              This mower is definitely a solid piece of equipment and, in general, the design trumps others in the class. However, the rear height adjustment only locks/catches on one side so there is a slight tilt to the mower that results in slightly uneven stripes. The cut quality isn't really better than the cheap mower this replaced. The engine (Kawasaki FJ180V KAI) is hard to start and hesisitates every time I tilt the mower back and turn around. If I had to do it again, I'd probably get a mower that's more focused on cut and engine quality even if slightly less durable deck and hardware design. Still a solid mower that will hopefully last for years and great design features (front wheel adjustment, engine guard, thick aluminum deck).
