Comments about Exmark 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.

Service and delivery comments:

Only wish I could name the dealer. Unlike any small engine equipment dealer I've ever used; professional and honest with excellent service. Interested in having a satisfied customer, even one who won't be buying several machines each year. Most dealers wouldn't entertain giving a very generous trade from one mower to another.

from Nashville, Tennessee

Comments about Exmark Commercial 21 X-Series:

I mow a two acre lot with an ex-mark Zero turn 60 inch cut and have been very pleased with the mower. I needed a trim mower for areas the zero turn can't get to. I compared Honda commercial vs ex mark 21 inch X series. Honda engines are hard to beat, but I was so pleased with my zero turn I went with the ex-mark 21 inch with the Kowasaki engine. Weight and handling are good, maintenance is low, mower is very easy to operate. I like the engine. It does not bog down in heavy/wet grass. The drive belt has had to be adjusted once since owning the mower. (Used for 4 seasons) Easy to do and not a big deal. The cut looks great! When bagging, the mower could use more weight on the front to keep the mower from tilting backwards. One big drawback. Engine can be hard to start if mower is not used regularly or when weather turns cold. I mow mostly fescue an it grows well into late November early December. A side discharge chute would be a nice accessory but is not available. Overall, I like the mower despite it's few drawbacks and would recommend purchase. Have NOT had to return mower to dealer for any maintenance or repair.

Service and delivery comments:

Had to order from Atlanta. Arrived promptly in new condition. Dealer provided excellent instructions and help to get started. Have not had to return mower to dealer for ANY reason.

Comments about Exmark Commercial 21 X-Series:

Poor design. Engine failed after 2 years, did not mulch at with the blades that orignially shipped with machine the dealer replaced it for free in 2 months. Now I have a machine that does not start after 2 seasons, not what you expect for a $1400 mower. You wont be able to remove the carburetor unless you take it to dealer and spend $350.

Great Bagging Mower

    Comments about Exmark Commercial 21 X-Series:

    I bought my Exmark 21" Commercial X Series unit in 2013 and have used it for 2 years in my part time lawn business. As a bagger, it is exceptional. It will suck up wet grass, tall grass, overgrown grass, leaves etc. with ease and very little gets stuck underneath the deck. Unfortunately, when attempting to mulch, it doesn't perform quite well as it leaves a lot of clumps. The engine doesn't sound like it can keep the blade spinning fast enough to cut the grass into fine clippingw. The other drawbacks I've found with the mower are:
    1. The drive belts seem to get loose quite frequently, especially if it's wet when you're mowing. It's easy to tighten them but it's annoying to loose speed when you're trying to get through your day.
    2. The kawasaki engine is powerful and great on gas but somewhat tempermental when you try to start it up in cold weather towards the end of the season.
    3. The bag never sits tightly against the frame of the mower. As a result, leaves, grass etc. can escape when bagging. A bungee cord fixed that.
    4. The cutting heights on the machine seem to be inaccurate. I first set the cutting height at 2.5". Yet, the cut appeared to be more at the 2.75 to 3" mark. This cutting height resulted in a lot of stragglers being left. Since then, I lowered the cutting height on the unit to 2" but it really seems like that's about 2.5" in real life. That has eliminated the straggler issue I had.

    Overall, it's a wonderful mower if you bag only. I was thinking of trying out the new toro 21" for mulching purposes but I'm not sure how well they work.

    Comments about Exmark Commercial 21 X-Series:

    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!

    Comments about Exmark Commercial 21 X-Series:

    The mower is the best walk behind mower that I have purchased when it is running properly. My first exmark 21 seemed to have quit a few problems with the carburator. The transmission also went out in the first year of use. I bought two more last year and didn't have any problems with them whatsoever. My mechanic has installed inline fuel filters in the fuel lines to help with carburator problems, which seems to help.
    The wheels are very durable, the mower has a great, tough, balanced feel to it.
