CARY, NC — John Deere is expanding its diesel mowing options with a new 72-inch (182.88 cm) deck size on the popular diesel Z994R ZTrak Zero-Turn Mower. The new 72-inch deck option increases operator productivity, particularly when managing larger terrains, while still offering premium quality, enhanced comfort, lower operating costs, and longer engine life. 

“We are committed to offering the commercial mowing industry a variety of equipment solutions that meet the needs of professional landscape contractors. With the 72-inch deck offering on the Z994R, we are able to provide even more options for the diesel market,” said Natalie Haller, product manager, John Deere. “Many of our customers manage areas with fuel restrictions, such as cities or governmental properties, which often require a diesel machine. With the addition of the 72-inch deck on the Z994R, we are providing customers with a powerful, reliable, and productive diesel solution.”

The Z994R mower is powered by a Final Tier 4, three-cylinder, liquid-cooled diesel engine with gross SAE J1995, PS 24.7 hp (18.4 kW) rated power at 3200 rpm. The high-torque, low-emission diesel engine provides power for tough conditions with low vibration and noise levels. 

Equipped with a single 11.5-U.S. gal. (43.5-L) diesel fuel tank, the Z994R provides enough fuel capacity for long mowing days, and offers an easy-to-read fuel gauge. 

Two seat options are available for the Z994R that feature the ComfortGlide suspension seat, providing two inches of fore and aft movement to absorb bumps for enhanced ride quality.  In addition, a large, open operator station and foot platform provides plenty of legroom, allowing for multiple foot positions for increased operator comfort. 

In addition to the 72-inch deck size, the Z994R is available with a 54-inch (137.16 cm) or 60-inch (152.4 cm) 7-Iron PRO side-discharge mower deck, or the 60-inch (152.4 cm) 7-Iron PRO Mulch On Demand mower deck.

Those attending GIE+EXPO, held in Louisville, Ky. from Oct. 16-18, can see the Z994R and the new 72-inch deck offering at John Deere booth #1110. To read more about the Z994R Diesel ZTrak Zero-Turn Mower, as well as the full line of John Deere commercial mowing equipment, go to
