California’s Central Valley is full of many perfectly groomed and picturesque lawns. Behind every amazing lawn is a landscaper who works hard to maintain the level of care that their customers expect. But you can’t maintain a beautiful lawn without the right equipment. That’s where the John Deere Z994R comes into play. This diesel-powered zero-turn commercial lawn mower is ideal for Central Valley landscapers seeking to maintain a high level of care throughout the year. Discover what makes the Z994R a game-changer for California landscapers. 

Engine & Power

The Z994R has plenty of engine power to tackle your toughest landscaping tasks. With a 24.7-horsepower 3-cylinder liquid-cooled diesel engine, you won’t have to worry about mowing down small shrubs or thick, overgrown vegetation. It’s also plenty of power to maintain that crisp and clean lawn that your customers expect. This zero-turn mower also has a high-torque, low-emission design that makes it suitable for easy to tough mowing conditions. The indirect fuel injection provides a smooth, quiet operation, so you won’t have to worry about noise complaints from your clients or their neighbors.

Mower Deck Options

The mower deck on the Z994R is a powerful 7-Iron PRO Mower Deck, with options for 54-inch, 60-inch, or 72-inch side-discharge decks. For grass clipping discharge on the back of the mower, you can opt for the FastBack PRO rear-discharge deck, perfect for keeping lines clean. With the 7-Iron Pro deck, you won’t have to worry about durability; this deck is meant to last. Constructed with cast-iron spindle housings, 5.5-inch deep 7-gauge steel, and UHMW polyethylene deck bumpers with steel reinforcement, this mower deck will endure the toughest jobs season after season. For mulching, a 60-inch Mulch On Demand deck option is available, which converts from a side-discharge to the mulching setting with a single lever.

Comfort & Operator Station

Not only is this mower known for its power, but it’s also known for its comfort. The ComfortGlide Suspension system is available on this model and others in the series. This full-adjustable suspension seat also has an adjustable footrest and steering control positions to maximize comfort. The flat operator platform makes it easy to enter and exit from the mower as well. On the operator station, you’ll find color-coded controls to make it easy to quickly identify different mower settings. This is a mower you won’t mind operating all day long.

Emissions & Compliance

California has strict machine emission regulations, and the Z994R is designed to meet all of those regulations when operating. This mower is Final Tier 4 compliant, meaning it meets California’s emissions standards for a diesel engine. In addition to being better for the environment, the Z994R is also great for your wallet, thanks to its 11.5-gallon fuel capacity. This allows operators to mow all day without stopping to refuel.

Industry-Leading Warranty

John Deere has one of the top industry-leading warranties for mowers. The 2-year unlimited hours or 3-year/1,500-hour bumper-to-bumper warranty will get you through your toughest seasons with the confidence that costly repairs will be taken care of. This is a great warranty for commercial landscapers who want to protect their investment throughout high-use commercial operations.
