Bad Boy Mowers MZ Magnum Zero-Turn Mower vs John Deere Z320R Zero-Turn Mower

The Bad Boy MZ Magnum is the heavier-duty machine: a 7-gauge fabricated deck, Hydro-Gear ZT2200 drives, up to 9.65 km/h and a 48 or 54 inch cut suit larger, rougher yards and long-term durability. The John Deere Z320R is the more refined residential mower: the 42-inch Accel Deep deck is known for clean mulching and bagging, and Deere's dealer network and parts support are strong. Owners of both praise cut quality; Bad Boy buyers cite rugged build, while Deere buyers cite fit, finish and resale. Pick the Bad Boy for size and toughness, the Deere for a tidy cut on a smaller lawn.

  • Choose the Bad Boy MZ Magnum if you have a large or uneven yard and want a thick fabricated deck, wider cut options and faster ground speed.
  • Choose the John Deere Z320R if you have a smaller lawn, mulch or bag often, and value dealer support and a clean, even cut.

What reviewers say

Bad Boy Mowers MZ Magnum Zero-Turn Mower

Owner feedback on the MZ Magnum centers on its sturdy build and clean cut for the money, with the fabricated deck and Hydro-Gear drives singled out. Complaints tend to focus on ride comfort, weight and the modest top speed.

What people mention
  • Deck buildPraisedOwners say the thick fabricated steel deck shrugs off impacts that dent lighter decks.
  • Cut qualityPraisedReviewers report an even cut and good discharge in thick, uneven grass.
  • Ride comfortCriticisedThe firm ride and basic seat draw complaints on rough or long mowing jobs.
  • WeightMixedThe heavy build feels solid but can rut soft ground and makes loading harder.

John Deere Z320R Zero-Turn Mower

Owners of Deere's residential zero-turns generally rate the cut quality and maneuverability highly and call the Accel Deep deck a real step up from flat decks. Common complaints center on the firm ride, small fuel tank and the price premium over box-store brands.

What people mention
  • Cut qualityPraisedOwners say the Accel Deep deck leaves an even cut and mulches clippings well.
  • ManeuverabilityPraisedLap bars are described as responsive and easy to learn for trimming around obstacles.
  • Ride comfortCriticisedThe lack of suspension makes the ride harsh on uneven ground, according to owners.
  • Fuel tankCriticisedThe 3-gallon tank is called small, forcing refills on larger lawns.

Questions and answers

Which is better for a large lawn?
The Bad Boy MZ Magnum. Its 48 or 54 inch cut, 5-gallon tank and higher top speed cover more ground per pass and per fill than the 42-inch Deere.
Which gives a better cut for mulching?
The John Deere Z320R. The Accel Deep deck's airflow is designed for mulching and bagging, while the Bad Boy needs a mulching kit and discharges by default.
Which lasts longer?
The Bad Boy's 7-gauge fabricated deck and ZT2200 drives are built for heavier duty, but its warranty is personal use only. The Deere holds up well with dealer-backed service. Longevity depends most on maintenance.
Is the John Deere worth stepping up to over the Bad Boy?
Only if a tidy cut, mulching, dealer support and resale matter more than cut width and deck toughness. For big or rough yards, the Bad Boy is the stronger tool.
Can either handle hills and rough ground?
Both are zero-turns with lap-bar control. The Bad Boy's weight and wider tires suit uneven ground better; the Deere is easier to handle on smaller, smoother lawns.
Do both bag clippings?
The Deere offers bagging through its Accel Deep deck and optional bagger. The Bad Boy side-discharges and needs a separate bagging or mulching kit.
