Zoomlion’s 9DX is a four-track tractor rated at 1,600 horsepower, nearly double the output of the machine it is being measured against. The Chinese equipment maker shows it as a hybrid, a big diesel paired with an 800-volt electric system.

The tractor appeared at the China International Agricultural Machinery Exhibition in the week of Nov. 6. Claims of the world’s most powerful tractor come from the manufacturer and the press that repeated it, and several basic facts, including weight and battery size, have not been released.
The 9DX numbers Zoomlion has released
The Drive lists about 5,300 pound-feet of torque, a top speed near 25 mph, the ability to climb 12-degree slopes and hydraulics rated at 168 gallons per minute. Its tracks are 30 inches wide. Electrek puts the metric figures at 7,200 newton-meters and 636 liters per minute of hydraulic flow, and describes a continuously variable transmission behind the hybrid system.
Tractor Junction notes a dual-motor coupling arrangement and rubber tracks 762 mm wide, built to spread weight and limit soil compaction. Zoomlion pitches the machine for wide seeders and large tillage tools, and claims lower fuel use, emissions and operating cost than a diesel-only design.
Scale helps explain the interest. At 5,300 pound-feet, the 9DX torque claim is about 70 percent above the 3,123 pound-feet Deere quotes for the 9RX 830, and Zoomlion’s hydraulic rating of 168 gallons per minute matches the top-rated Deere according to The Drive. Top speed near 25 mph on any terrain is a notable number for a machine on four tracks, though speed matters little to the wide-implement work Zoomlion describes.
Against the John Deere 9RX 830
The comparison point is Deere’s flagship. The Drive’s earlier report gives the 9RX 830 a rating of 830 horsepower from an 18-liter six-cylinder, 3,123 pound-feet of torque and a base price of $1,226,908. Its maximum output reaches 913 horsepower, the figure The Drive uses as the benchmark, so the 9DX claim is roughly 75 percent higher.
That gap sounds decisive, but horsepower on a spec sheet depends on how it is measured. Zoomlion’s 1,600 is a combined diesel-plus-electric figure, and tractor peak ratings often differ from sustained drawbar power. Nobody has published a drawbar test of the 9DX, so field performance relative to Deere remains an open comparison.
The setting adds context without adding proof. Electrek says the exhibition drew more than 3,000 exhibitors and vendors, and that Zoomlion describes the hybrid system as a way to cut fuel use and emissions while still relying on diesel rather than replacing it. A trade show is where claims are made, not tested, and nothing published so far shows the tractor working a field, pulling a measured load or running with a stated battery capacity.
What is still missing, and the U.S. outlook
The diesel is unnamed. The Drive suggests a variant of the Cummins X15 used in Zoomlion’s ZR400U drilling rig, whose page sits on the company’s product site, but that is the author’s guess. Electrek says there is no official word on batteries, though Zoomlion’s 800-volt packs for other machines range from 140 to 800 kWh. Weight, price and sales start are also absent from every report read.
Price is the other unknown. For reference, Deere asks $1,226,908 for the base 9RX 830, and a Chinese machine with a larger hybrid system would plausibly carry a comparable or higher figure, but Zoomlion has published none. Without a price, dealer plan or sales start, the 9DX is best read as a technology demonstration from a company better known for forklifts and scissor lifts in the U.S.
Why the machine exists is clearer than how it performs. Very large farms in China and elsewhere run wide implements across flat ground, and the pitch for a hybrid is to supply a surge of electric torque at low speed while the diesel runs in an efficient band. That logic is Zoomlion’s claim as relayed by the sources, and the actual fuel savings were not quantified in any report read for this article.
The Drive’s Caleb Jacobs doubts the tractor will reach American farms, citing heavy tariffs on Chinese agricultural equipment, a preference for domestic brands and the lack of a dealer network that could handle repairs on a machine this complex. Zoomlion mainly sells forklifts and scissor lifts in the U.S. today.
The decisive evidence will come from the first independent measurement. A published dyno figure or a drawbar test, plus a disclosed battery and engine, would show whether the 1,600 number holds up outside an exhibition hall. Until then the record claim stands as a manufacturer’s statement, one that Future Farming, quoted by Tractor Junction, says it will update once more technical data appears.
