Shipping Details

Built for homeowners who want a great-looking lawn in less time, the John Deere® Z320M zero-turn riding lawn mower combines zero-turn agility, proven durability, and easy-to-use controls. Its powerful 21.5-HP John Deere® V-twin engine and 42-in Accel Deep™ mower deck deliver a clean, consistent cut on properties up to 2 acres. Built in Greeneville, TN, USA, using domestic and imported materials.

Power through up to 2 acres: John Deere® 21.5-HP V-twin engine with dual hydrostatic transmissions delivers a smooth, responsive control and forward mowing speeds up to 7 MPH
Professional-quality cut: 42-in Accel Deep™ mower deck is engineered to deliver a clean, even cut with excellent grass lift and clipping dispersion, even at higher mowing speeds
Built for season-after-season durability: Reinforced frame and durable stamped steel mower deck are designed to withstand years of regular residential mowing
Zero-turn maneuverability: Turn in place to mow efficiently around trees, flowerbeds, and other obstacles while reducing trimming and overall mowing time
Stay comfortable longer: Adjustable 20-in high back seat, color-coded controls, and large front tires provide a comfortable ride and intuitive operation that help reduce operator fatigue
Integrated park brake activates when you are done mowing, automatically engaging when the steering levers are in the outward position
Ready for bigger mowing jobs: Large 3-gal fuel tank maximizes mowing time, while the standard front bumper and rear hitch add durability and versatility
Customize your mower for year-round versatility: Compatible with an optional bagger (1208518), MulchControl™ kit (2636754), broadcast spreader (317782), and dump cart (317783), all sold separately

What Customers Are Saying

Customers overwhelmingly praise the mower's exceptional cutting performance, particularly in thick grass, and consistently highlight its solid, durable construction with a 21.5 HP Kawasaki engine. Many first-time zero-turn users find it intuitive and enjoyable to operate, with reviewers noting professional-grade results and fast mowing times. The mulching attachment receives frequent praise. A few customers experienced minor defects upon delivery or isolated mechanical issues, but these concerns are vastly outweighed by satisfaction with the machine's power, precision, and overall value.

Would Not Recommend

Lawn mower would not go forward nor backward. Calling Lowe's customer service resulted in going in circles. There was no better outcome in contacting John Deere customer service. This was too much of an investment to not work from day 1. Reluctantly, I decided to return.

Good purchase.

Would Recommend

I have had good experience in my first two mowings. The delivery was good and product is working as expected. It did come with zero gas so testing while the driver was here did not happen.
