The new 600 Vario versus the 700 Gen6 Vario

The new range includes the 614, 616, 618 and 620 Vario models, covering a power bracket from 149–209hp.

The 620 Vario – the most powerful in the series – formed the centrepiece of a day of presentations, comparisons and field demonstrations, with attendees given a unique opportunity for a side-by-side comparison with hands-on access to both the new model and the outgoing 700 Gen6 Vario.

Big shoes to fill

The 700 Gen6 Vario series has been a benchmark in the 140–240hp bracket for years, so replacing it was never going to be a small task.

Yet, on paper, the new 600 Vario series appears to be well-equipped for the challenge. Its new 4-cylinder 5-litre AGCO Power engine delivers 950Nm of torque over a wide rev range from 1,200–1,600rpm.

Key to this performance is a brand-new engine with increased bore and stroke, pushing displacement up without compromising on efficiency.

This, combined with the Fendt iD low-speed engine concept improves fuel efficiency, reduces engine noise, and reduces long-term mechanical stress.

Fendt has dropped exhaust gas recirculation (EGR) from the platform, meaning fewer replacement parts and potential lifetime savings on EGR maintenance costs – although this may come at the expense of increased AdBlue consumption.

What sets the 600 Vario apart in practice, however, is not just the power delivery, but the combination of power, manoeuvrability, and technology usually reserved for higher horsepower machines.

Immediate impressions

Test drives during the event allowed direct comparison between the 620 and the 724 Gen6, both on road conditions and with implements in the field.

On-site demonstrations included runs with a Väderstad 525 carrier, with machines swapped between tasks.

While full-depth testing wasn’t feasible in the limited field and road conditions, the hands-on comparison still provided a clear sense of each machine’s capability.

Across both the road and field sessions, the 620 had the presence and pulling power of a 724 Gen6 but felt noticeably more agile – a clear advantage when it comes to navigating headlands, transport, and loader work.

Both tractors handled the field work confidently and with ease, but the 620 impressed with its strong low-end torque and notably quieter cab – impressive, given the already quiet cab of the 724.

The iD low-speed engine concept allowed the 4-cylinder engine to hold down revs under load, delivering smooth, consistent performance without strain. The VarioDrive ‘pull-in turn’ feature noticeably reduced headland scrubbing.

Another standout feature available on the 600 Vario series is Fendt’s integrated VarioGrip tyre pressure control system.

Operated through the FendtONE interface, VarioGrip allows drivers to adjust tyre pressures on-the-fly from the cab while driving, optimising contact area and traction depending on field or road conditions.

Fendt claims VarioGrip can deliver up to 10% more tractive power in the field and cut fuel consumption by up to 8% compared to standard tyre setups.

During the event, attendees were shown live demonstrations of the system in action, emphasising its role in reducing soil compaction, improving fuel efficiency, and boosting tyre life.

For operators moving frequently between road and field work, the ability to adjust pressures on the move offers a tangible boost to productivity and operating economy.

Fuel efficiency comparison

Two approx. 10.5 mile road loops gave a useful real-world comparison of handling characteristics and fuel consumption.

Both tractors were towing a Ktwo 16t trailer which was half loaded with fermented maize. On identical routes on typical British country lanes, the 620 recorded an average of 2.6-litres less in diesel burnt.

This is likely reflective of both the 620’s lighter chassis and the efficiency gains of its newer engine platform.

Also of note is the increase in AdBlue consumption in the newer 620, where over the same journey, an average increase of 2-litres/100km AdBlue consumption was recorded.

When queried on this, Fendt’s product specialist Philip Mattey commented that any increase in cost from the increased AdBlue consumption would be more than offset by the reduced fuel consumption and lifetime maintenance costs associated with the outgoing EGR system in the 700 Gen6.

The brand estimates users could save thousands over a machine’s working life on fuel and maintenance costs alone. Regarding fuel consumption on-field, data was also collected.

Both tractors were on a Väderstad 525 Carrier, with equal linkage heights and press roller heights, and no wheel weights, with a front 1,250kg weight.

Fields were barcoded to ensure fair results. The 620 burnt on average 2.6-litres less of diesel, equating to an average decrease of 6.5-litres/hour.

Fendt says that the new engine architecture is designed not just for efficiency but lifetime value. Fendt also highlighted how more fuel-efficient engines increase operating windows – and how less time spent refuelling tractors equals more time working the land.

Cab and interface

Fendt’s cab design has always prioritised operator comfort and the new 600 Vario series is no exception.

The cab is spacious and flooded with natural light. Visibility is superb thanks to over six square metres of glass and 77-degrees upwards viewing – ideal for loader work.

The FendtONE interface is a key component of that design, offering a 12in touchscreen control terminal and a 10in digital dash, allowing for custom layouts, implement controls and tractor settings.

Ergonomics are also excellent, with an intuitive multi-function joystick, comfortably positioned and shaped armrest, and a premium air-suspended seat with memory.

The range topping Profi+ model that we drove also had a leather seat with heating, cooling, and even a massage setting.

Combined with the clear layout and accessible multifunction joystick controls, the cab strikes an appropriate balance between intuitive use and high-end tech appeal.

It’s a setup that helps reduce fatigue, which Fendt says is particularly welcome during long stints on loader or cultivator work.

Loader ready

While not demonstrated during the event, Fendt’s loader offering formed a significant part of the press presentation, and loader users are a clear focus for this range.

The 600 series’ chassis is designed for full front-loader integration, with a Z-bar linkage and mechanical self-levelling. As previously mentioned, visibility is excellent, and the joystick layout allows rapid cycle times with reduced effort.

Smart functions include the option for two programmable memory settings for the loader arm and load weight feedback via integrated sensors.

The tighter turning radius and lighter footprint of the 600 series also work to make it a strong contender for yard work, bale stacking, and tight-space handling.

600 vs 700 Gen6: how it compares

While Fendt has clearly positioned the 600 Vario series as a replacement for the 700 Gen6 Vario, this is more than a power-for-power swap.

The 600 Vario is lighter, more efficient, and more technologically advanced, offering improved payloads – 5.8t compared to 4.8t – and introduces several efficiency-first features such as VarioGrip tyre pressure adjustment and VaroDrive all-wheel management which provide tighter turning and greater economy in both field and transport settings.

Its 4-cylinder engine challenges the assumption that more cylinders are always better in this power class – and early data shows the 620 matches or exceeds the 724 Gen6 in key areas while burning less fuel and operating more quietly.

Therefore, Fendt’s 600 Vario makes a compelling case as the next evolution in the 140–240hp bracket.

Smart engineering, high operator comfort, strong loader capability and tangible efficiency gains all support its pitch to replace the long-serving 700 Gen6 Vario.

For operators looking to reduce running costs without sacrificing power or precision, the 620 Vario in particular looks well-placed to become a key contender in Fendt’s mid-range lineup.
