Over the past decades, using heavy farm tractors in the earthmoving business has become commonplace. They can perfectly tow heavy loads, the off-road capabilities are excellent and with a legal speed limit of 40 km/h (25 mph), these big-4WD-machines can also cover short distances on public roads just fine. No worries about good comfort and ergonomics either.
This New Holland’s job is towing a BECO dump trailer, both on- and off-road. It’s powered by a 6.7 liter FPT Industrial-NEF engine, as in Fiat Powertrain Technologies-New Engine Family. A turbocharged and intercooled inline-six diesel with an SCR aftertreatment system (DEF required). Its maximum power output is 180 DIN-hp, 199 DIN-hp when the boost kicks in at a speed of 15 km/h.
The tractor is equipped with the AutoCommand transmission, which is a CVT with a dual clutch. On the tractor’s left side you can see the tank unit for the diesel fuel (black cap) and the DEF (blue cap).
The on-road top speed in this segment of farm tractors is around 50 to 60 km/h, but as mentioned above, the legal limit is 40 km/h. The New Holland’s lowest speed? 200 meter (219 yards) per hour!

As heavy-duty as a heavy-duty hitch can get. Everything locked and secured.
Now to the trailer, BECO is a Dutch manufacturer of agricultural and earthmoving equipment. The dump bed capacity of their Maxxim 260 model is 17.2 m³ (607 ft³). Worth mentioning is that the trailer’s chassis features fully closed structures.
BECO guarantees a payload capacity of 26,000 kg (57,320 lbs), hence the number 260 in the model designation.
The company’s biggest and heaviest dump trailer is the tridem axle Maxxim 360, as seen in action here, also being towed by a New Holland T7.

The owner ordered the optional steering rear axle.
Another example of an eartmover, I caught this combination at an exhibition, two years ago; a tridem axle Joskin trailer, towed by a John Deere 7230R. Both the trailer’s first and third axle are steering axles.

Earthmoving companies have to move more than just earth. This older New Holland model, a T7030, tows a type of trailer that is usually coupled to a powerful dump truck, mostly with four axles (8×4, 8×6 or 8×8).
Now I wonder when the first “high-speed” farm tractors appear on our freeways…
