Greenworks MaximusZ MZ606 Zero-Turn Riding Lawn Mower Review

The MZ606 is a residential battery zero-turn built around a 60-inch stamped-steel deck, brushless motors and a six-bay battery system. Greenworks sells several MaximusZ sizes and voltages, so specifications from another MaximusZ model do not apply here: the MZ606 is the 60V, 60-inch machine, and every figure on this page is its own.

The headline numbers set the scale. The deck cuts 60 inches wide, the drive tops out at 8 MPH, and the machine is rated for up to 105 minutes or 4.4 acres on the included packs. Greenworks puts the gas equivalent at 31 HP, and the mower weighs 1,120 lb.

A wide deck and a fast top speed are what turn a big lawn from an afternoon into a couple of hours. The MZ606 pairs a 60-inch cut with three drive modes of 4, 6 and 8 MPH, so open stretches go quickly and fewer passes cover the same ground.

Battery capacity in the box

The mower ships with (2) 20.0Ah and (4) 8.0Ah batteries plus a 1.5kW fast charger. That is a full six-pack setup rather than a starter pair, and the charger refills the set in under 4 hours.

Four cutting options

Mulch, bag, side discharge and rear discharge all work out of the box. An integrated deck-wash port makes cleanup easier after a dusty session. Cut height runs from 1.5 to 4.5 inches across 7 positions on a single lever, which covers a close summer trim and a taller fall cut without tools.

Utility built in

A front 2-inch receiver hitch, a rear hitch and a rear cargo bin rated to 200 lb let the mower do more than cut grass. Towing capacity is listed as 300 lb in one place and 350 lb in another, so plan on around 300 to 350 lb.

Comfort and visibility

An LCD display keeps the key readings in view, dual LED headlights let you finish in fading light, and a rollover protection structure is fitted. The machine runs on battery, so it produces no fumes and far less noise than a gas mower.

Warranty

Coverage is 4 years on the tool and 4 years on the batteries. On a machine with six packs to look after, the battery term is the part that counts.

The 4.4-acre figure is the maximum with all six packs in tall, easy grass. Thick, wet or overgrown lawn draws more power, so plan on less and expect to recharge or add packs if your property runs large.

A hard slope ceiling

The manual sets a maximum slope of 15 degrees. The mower is rear-wheel drive, grip-limited and heavy, so it is not a hill machine. Steep banks and wet hillsides are out.

Big and heavy

At 1,120 lb, roughly 73 inches wide and about 77 inches long, the MZ606 needs real storage space, a wide gate or path, and firm ground. Soft turf will rut under that weight.

Battery rules to learn

The mower needs at least three batteries installed to run, and it only recognizes packs above 4.0Ah, so a small spare will not work. Six bays also mean six packs to charge, track and eventually replace.

Winter battery care

Assembly and deck material

The mower arrives requiring assembly. The deck is stamped steel, which is worth knowing if you expect a fabricated plate deck.

An unproven track record

Owner feedback on this model is limited, so treat long-term durability as unproven rather than settled either way.

These are the figures that shape day-to-day use, from the power source to the storage footprint.

The 60-inch cut, the 8 MPH top speed, the six included packs and the 4-in-1 cutting system are what justify this machine's place among large-deck zero-turns.
