Greenworks MaximusZ 7423702 Zero-Turn Riding Lawn Mower Review

The deck is the heart of a mower this size, and the 7423702 carries a 54-inch, 10-gauge fabricated steel deck with side discharge. Fabricated steel is the durable choice for a lawn that gets cut week after week, and the wide deck keeps mowing time down on a big property. Cut height runs from 1.5 to 4.5 inches across multiple positions, so you can leave more length in summer heat and drop lower in spring.

Power delivery and cut quality

Five brushless motors do the work: two hub-drive motors at the wheels and three blade motors under the deck. Blade-tip speed reaches about 18,400 FPM, which is what lifts established turf and leaves a clean cut rather than a torn one. Brushless motors have no brushes to wear out, and with no engine there is no engine oil, no spark plug and no carburetor to service.

The battery kit as shipped

The box holds (2) 20.0 Ah suitcase batteries and (4) 8.0 Ah batteries, all 60V, plus a 1.5 kW rapid charger. That is a large amount of onboard energy for a residential battery zero-turn, and it is what makes the advertised acreage plausible on a well-maintained lawn. Runtime runs up to about 72 minutes on the included packs, and a recharge takes under about 2.5 hours with that charger, which is fast for this class and matters if you mow most days.

Comfort and control

The seat is an adjustable suspension unit with lumbar support and fold-down armrests, which helps on a two-hour session. A 4.0-inch LCD display with USB-A and USB-C keeps a phone charged, two cupholders hold a drink, LED headlights let you finish at dusk, and a roll bar comes standard.

Utility beyond mowing

A rear dump bed rated to 200 lb and a towing capacity of 300 lb, with a front 2-inch receiver hitch and a rear hitch, turn the machine into a working vehicle. It hauls mulch, tools and a small trailer around the property, which is a real differentiator against a mower that only cuts grass.

Quiet, gas-free operation

There is no fuel to buy, no oil to change and no exhaust. The noise level sits far below that of a gas zero-turn. The 60V packs also run a large family of the brand's 60V tools, so the batteries earn their keep off the mower. The warranty is 4 years on the mower and 4 years on the batteries for residential use, and 90 days for commercial use.

The rated maximum slope is 15 degrees, and that is the single biggest functional limit for US buyers. Anyone with a steep bank, a ditch or a hilly back acre should treat this as a flat to gently rolling terrain machine. Drive goes to the rear wheels only, so traction on wet or loose grades is the constraint, not motor power.

Runtime depends on conditions

The advertised acreage assumes favorable conditions. Tall grass, wet grass, slopes and heavy deck overlap all cut into it, because each one draws more energy per square foot. A homeowner who lets the lawn get ahead, or who mows damp, will not see the advertised figure. That is how battery runtime works, not a flaw in the machine.

Three batteries minimum, and only larger packs

The battery compartment has three columns, one for drive, one for the left blade and one for the right blade, and the machine needs at least three batteries installed to run at all. It also only recognizes packs above 4.0 Ah, so a couple of small existing packs will not get it moving.

Charging logistics

Mulching

The deck is a side-discharge unit. A mulching plug is a separate accessory, so a buyer who wants to mulch should plan for it rather than expect it in the box.

Service logistics and warranty exclusions

The machine weighs 1091 lb. Warranty service means transporting it to an authorized service center at your own cost. Blades, belts, lubricants, blade sharpening and cosmetic finish deterioration are not covered. The product must be registered, and commercial use drops coverage to 90 days.

Physical footprint

The deck is 54 inches wide before the discharge chute, the machine is 1091 lb, and the machine is roughly 56 inches wide overall.

The battery set adds up to a large watt-hour capacity. Real results move with grass height, moisture and overlap. The 8 mph top speed and the 22-inch rear wheels are what let you cover ground quickly between passes.

The practical spec that surprises buyers is the battery rule: three packs minimum to run, and only packs above 4.0 Ah are recognized. The 200 lb dump bed and 300 lb towing rating are what make the machine useful after the grass is cut.
