Exmark Takes Productivity to a New Level with 144-Inch Lazer Z Diesel

All-new zero-turn rider is capable of replacing up to three 72-inch machines

Today at the GIE+EXPO trade show in Louisville, KY, Exmark unveiled its largest, most powerful commercial zero-turn mower – the 144-inch Lazer Z Diesel. Capable of cutting up to 11.5 acres per hour, the new machine sets a new standard for zero-turn productivity.

According to Exmark Product Manager, Lenny Mangnall, the 144-inch machine is exactly what the company’s customers need in light of ongoing labor shortages and an increasingly competitive marketplace for landscape maintenance professionals.

He said the machine’s increased productivity can replace up to three 72-inch mowers and operators.

“Whether they’re looking to make more money, or simply finish mowing faster, our customers are always looking for ways to empower each worker to do more,” Mangnall said. “The new 144-inch Lazer Z Diesel is built to give these users the speed and capacity to finish jobs quicker, with less effort than ever before.”

The new Lazer Z Diesel features an incredible 144-inch UltraCut rear discharge flex wing cutting deck, which pairs a 48-inch center deck with two 48-inch wing decks. Capable of articulating 20-degrees up and 15-degrees down, the floating wing decks minimize scalping while enabling maximum productivity when mowing in uneven conditions. The deck uses six matching blades and a rear discharge design to deliver maximum productivity and an unmatched finished cut quality.

To ease transport, both wing decks fold hydraulically to ease loading and unloading, and reduce required trailering space. This enables the 144-inch Lazer Z Diesel to fit on industry-standard trailers that are designed for 72-inch machines.

Powering the 144-inch Lazer Z Diesel is a 43.5-horsepower* Yanmar three-cylinder diesel engine. Equipped with common rail fuel injection and a turbo charger, the engine delivers the torque necessary to power through the toughest cutting conditions without compromising speed or cut quality. Designed to be extremely fuel efficient and clean running, the Yanmar engine meets EPA Final Tier 4 emissions standards.

Dual variable-speed fans increase speed as engine temperature rises to keep the engine cool, and the fans reverse at set intervals to loosen any debris build up. The fans also tilt out to ease removal of accumulated debris.

The 144-inch Lazer Z Diesel features a two-speed drive mechanism. The low range (0-10mph) provides maximum torque and mower control, while the high range provides a top speed of up to 17mph, ideal for transport. The transmission is directly coupled to the engine without drive belts, for a more efficient, robust drivetrain that significantly reduces service and maintenance requirements. This maximizes uptime and delivers a lower total cost of ownership when compared to other commercial zero-turn mowers.

Operator comfort was a primary consideration for Exmark in the development of the 144-inch Lazer Z Diesel. Isolation mounts under the seat base and footrest, and within the motion control system, provide three-dimensional isolation from vibration transmitted through the mower frame. Exmark’s new 4-inch travel full-suspension operator seat features a scissor link ball-bearing suspension system, Elastomeric Vibration Control (EVC) stretch fabric base and custom seat cushion foam. The combination delivers the comfort operators need to maintain a high level of productivity throughout the day.

The Lazer Z Diesel is also available in 60-, 72- and 96-inch models. Each includes Exmark’s industryleading 5-year/1,500 hour warranty, with no hour limitations in the first two years.
