Item Information

Most mowers at this price are made from flimsy stamped steel and bolted together. So if you're looking for the efficiencies of a zero-turn mower at a price that does not compromise on quality construction and quality of cut--turn to the Bad Boy MZ Magnum. With its all new, larger and stronger frame - sporting an even stronger 7-gauge all-steel, fabricated deck - the MZ Magnum is far more substantial in build quality than other mowers in this price range. You'll immediately appreciate the rock-solid, all-steel welded construction, powerful engine and 'too much fun to call it work' ride.

Rated 5 out of 5 by from NASCAR mower We own a ranch, the yard area is 3 acres, I have never had such a smooth cut yard like what this Mower does, it’s fast, smooth and so easy on myself and wife.. we even cut s 54” pass on all our fence lines.. we were at 2 1/2 hours before, now about 45 minutes.. tried to remove one of the blades to sharpen it, couldn’t break it loose. Made a call to bad boy mowers, never had anyone go beyond to help and make it all good.. what an A+ for customer service, I feel if this is the way they take care of there customers, no wonder why, there product is as great as it is .. way to go guys, ya hit this one completely out of the yard and pasture

Rated 5 out of 5 by from bad boy is definitely a bad boy never owned a zero turn . because it cuts better than any of tractor types I've owned, my grass was tall waiting for this mower but when I got it , it walked through 9" of grass with no problem, I would definitely recommend this bad boy to anyone, , I mowed up steeper hills than recommended. when I got on it and took off it had so much power it almost through me off, wife said you need a seat belt.

Rated 4 out of 5 by from Bad Boy MZ Magnum 54” Very pleased with this purchase, just made my 5hr oil change and have to say this Bad Boy Magnum cuts very smooth and efficiently! Would certainly recommend this mower!

Rated 5 out of 5 by from This mower is a BEAST! Buying the Bad Boy MZ Magnum is the best decision I have made related to mowers ever. It is strong, easy to operate, easy to clean and very comfortable, I could sit on this mower for hours without a problem. The only thing I would change is the tire size, the rear tires are a little small for this mower, it could easily handle a larger tire to reduce spinning.

Rated 5 out of 5 by from Bad Boy MZ Very happy with its performance and ease of operation.

Rated 4 out of 5 by from First Zero Turn Had spoken with neighbor about the bad boy and felt like it was an overall good fit for our acre lot. And after 3 weeks we are not disappointed. Good speed and braking, cut quality is consistently good.

Rated 5 out of 5 by from Beautiful machine , Well made in the USA . When I call on how to adjust a part I actually talked to an American worker who knew this machine inside out !!! Wow that has not happened in years . He told me now to fix the machine quickly and easily and clearly! I’ve owned this machine now for 3 seasons and it runs perfectly. I have 3 acres of grass on a hilly terrain with edge trimming around many gardens ; this mower does it all . It’s stable on hills , fast on level ground and fuel efficient ; about 2 gal / 3 acres. Other then sharpening blades , changing oil and filters each yr and a few small adjustments I’ve had no other problems!! I cut all my grass in 2hr ! Before this machine I had a 61” cut commercial Scagg . It took me 3 hrs to do the same cut ; with frequent repairs . It does cut up my turf a little on tight turns . I may need to change tires tread design . Blades are a little tuff to get to to service ; you will need a good jack . I’m 70 and probably I’ll never need another machine but if I did it would be another Bad Boy for sure . Thank you for a well made machine .

Rated 3 out of 5 by from First mower blew engine I've had my 54" bad boy for a while now. The 1st one I bought the motor blew on the Kohler engine. After that i had to be upgraded to the bigger Kawasaki motor and I also use the pecco vac system for my collection. Mower is very long so do not plan on using this for small yards.

Rated 5 out of 5 by from My new toy Bought the mz magnum just recently a this ovef nd I've got to say it is a "bad boy". Cut my grass cutting time in half and the cut is sooo smooth. My first zero turn, and glad i chose this over other brands. Definitely worth the extra bucks. Makes cutting grass a blast. Id give it 10 stars if I could. Never thought I'd be wishing my grass would grow faster. Tons of asseccories online. Gonna add lights and rops. (Roll over protection system ).

Rated 5 out of 5 by from Why we bought the MZ Magnum We took a couple of weeks comparing mowers and finally decided to buy the MZ Magnum. It isn't tack welded like the others we looked at, it's made so much better than the others in this price range and better. It's wonderful. It cuts what used to take 30 minutes in 10 minutes. Drives like a dream, completely love it!!

Rated 4 out of 5 by from Bad Boy pros and cons nice mower, but handles were too stiff. Had to put a softer spring on it. Also, cannot pull choke knob out by hand and was extremely hard to pull even with pliers.

Rated 5 out of 5 by from Best mower I’ve owned yet This mower is amazing. I’ve owned a cub cadet in the past and this blows the cub out of the water. Deck adjustment is super easy cuts really nice lots of power and fuel gauge is a pretty good feature. And the cup holder!!! I would recommend this to anyone in the market for a mower.

Rated 5 out of 5 by from One Heck of a BadBoy I have owned a couple other zero turn mowers, but this by far is the Best zero turn mower out there for the money. It is built very very well & does a super job cutting grass. It is designed well, with easy access to belt, oil filter, fuel filter. I would put this BadBoy up to any mower out there!!!!

Rated 5 out of 5 by from Zero turn that you will not be disappointed with!! This is the first for me to use a zero turn. I use to have a riding mower and it was good but the Bad Boy is twice as fast to get the job done. I like the power this mower has and the speed is nice too. The floor board/ deck hood, makes it easy to work on the spindles or pulleys. I have mowed my yard once because the heat is killing my grass but when it comes back i will be ready.

Rated 4 out of 5 by from Bad Boy MZ Magnum 54in. as a Cub Cadet upgrade I upgraded from a Cub Cadet LT1050i, which I have owned for 11 years to the Bad Boy MZ Magnum 54 in. Zero-Turn Mower. My primary objectives were to reduce mowing time, have a sturdy robust mower that will last many years, and that can be easily maintained. I have used the mower twice, and is satisfied that it does in fact slightly reduce the mowing time. Drawbacks however include that it is not as fast as other more expensive zero turns, and it is better suited for flat and even surfaces. It however suffice for my needs and I am happy at this point.

My badboy developed a problem - it won't start. It appears to be in the interlock system. If you wiggle the right control arm a small amount, it will start but then you have to quickly release the brake. I need a wiring diagram.

Asked by: John0831
The wiring diagram is available in the owner's manual provided with the mower. The manuals are also available at You can also have your mower repaired by an authorized service location.
