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.

Bad Boy MZ Magnum 54 in. Zero-Turn Mower is rated 4.2 out of 5 by 109.
Rated 5 out of 5 by from Awesome mower! I bought this zero turn a few weeks ago and I love it! I have around 7-8 acres of grassland that I keep cut. It used to take me two 5 hours day with our old mower to cut it all, now it takes around two and a half hours! The mower is very strong. I definitely will be a Bad Boy Mowers owner from here on out!

Rated 5 out of 5 by from Durable The best mower hands down! We have 4 acres to mow and takes no time at all. No dust blow up, quiet running, and doesn’t shake rattle and roll. We love it! Great investment. And live the huge gas tank! Oh and we have all mesquite tress and thorns, tires are holding up great. No flats

Rated 3 out of 5 by from Maybe hit or miss If you have a yard with no big bushes, you'll be fine as far as plastic fenders hold up. Only 72 hrs on spindle bearings before replaced, tires not holding up. The deck is OK but the hangers stink. Replaced deck hangers with chain instead of solid link, so deck will have some give. A rear arm for the deck broke at the weld , that's on me. But after you weld it back and replace the solid link with chain make sure all bolts are the same. I had 3 different size bolt (only 8 bolts for hangers)for 4 identical mounting points on the mower. The steering arms are not very sturdy. Thist have been a Monday or Friday production mower. Kohler engine so far has been strong as an OX. LOVE MY TSC store but they might want to find a more reliable and mainteance friendly brand.

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.
