After 23 years of being in production, it was time for a successor to the Beet Eater 617.

Despite the difficult harvester market the last two years, we  invested in a completely new harvester. During the development ,we have tried to design a machine that makes it possible to fulfill almost all demands which are known on the market today, in one machine.

The result is our new Q-series.

The name Q-series  is mainly choosen  for "Quad". It's a 4 wheeler. But because the rear wheels are mounted close together, it has the same advantage as a trike, namely: the wheels each run in their own track. Or at least that choice is there. Because there are still people who do not want this per se. Q also reflects Quality, as we like to mention in our company motto: "Experiencing Quality".

The machine can perform under all circumstances. The Q-serie is in fact developed modular. There are three toppers available. 2 types lifting units , 2 tank sizes , two engines, and  four different chassis options. These different main choices creation no less then 288 editions in the Q series.


  • Tyres
  • Frame
  • Tank
  • Engine
  • Topper
  • Cleaning
  • Electronics

Both front and rear axle show multiple choice in tyre sizes.

At the front, therecan  be chosen for 710x42, 800x38 or 900x38 mm tires, while at the rear the selection consists of 800, 900, 1000 or 1050 mm, all of them 32 inch rims

Of course, the latest development in ultra flex tyres from different brands are possible.

Our expectation is to be able to drive the Q-616 just over  1 bar.

Like our 9row Beet Eater, with its pyramid arrangement of the wheels, the new Q-series wheels only have 1 passage. It is a huge advantage compared to  2 or 3 passages in a track, because the soil compaction is greatly reduced.

We would like to note that crab-steering harvesters also claim to have one wheel passage, while their wheels partly run in the same track 2 or 3 times.

Due to the rear axle which is mounted on a turntable, the machine is highly manoeuvrable, with an inside turning radius of only 2.4 metre.

The front wheels of course are also steered , with an angle of 8 degrees.

The front axle is a pivoting axle, which is provided with hydraulic cilinders to allow the machine to hang against on the slopes, making it more stable, and at the same time, reduce the weight on the wheel on the valley-side, thus also soil saving.

Optionally available is a fully automatic leveler controlled by a G sensor.

The Q-series will have tyre inflate systems optional.This allows the operator to inflate or deflate the tyre pressure on-the-move.

In addition to the tire options, it is also possible to equip the machine with a rubber tracked  front axle. This will, of course, greatly increase the contact surface of the front axle, which results in a lower ground pressure per cm2.

The major difference in comparison with the 617 on tracks, lies in the fact that the Q-series does not need to be equipped with a different harvesting unit. It can be simply adapted on a standard machine, which can then be switched at any time from tires to rubber tracks.

Another innovation is the tiltable T-fork. It can commute, just like the front axle. This makes it possible to let the whole machine tilt to the left or right. The rims have an offset of 10 cm, and can mounted Left or Right  on the wheel drive, so that one can choose from a narrow or wide wheel arrangement. In the wide arrangement, the outside wheeltrack measures 2.80 meters with a spacing of 70 cm. In the narrow  set-up, it is only 30 cm. It is conceivable that users on steep slopes will opt for the wide set-up. Or those who prefer to leave a strip of land un-touched by the wheels.


Not everyone is charmed by a large tank. Increasingly we have demand for a lighter machine. We have chosen to offer the new Q-series in 2 variants: the Q-616 and Q-621.

The Q-616's , has a fixed ring elevator and distributing auger. The capacity is calculated at 16 tonnes, which is enough for many customers.

However, to compete against the colleagues with the dog walk machines, we also needed a larger version. So the Q-621 has an extendable  ring elevator, auger and side extensions. As the name suggests, the capacity of this version is 21 tons.

The ring elevator is 20% wider then the previous 617 model, in order to smoothly charge the greater yields with less damage. Should the yield be lower, the speed can be further reduced which gives longer life and lower fuel consumption. In anyway, an advantage.

The discharge elevator is completely renewed. It now sits at the front of the tank, which gives a perfect view at the unloading process, and also keeps the machine's center of gravity low. The width is 1,40 metre, to better fill out the  trailers. The length of the valve is increased with no less then 80 cm. This allows us to discharge higher and / or further. By tilting the front axle, the height of the discharge elevator can further increased or reduced by 50 cm. (450cm max. and 190cm  min.) Due to the ever increasing trailer sizes,as well as the desire to unload directly into lorries, it will be a well received feature. The lower position was desired to reduce damage to the beets when starting to build a new heap. The length of the elevator ensures a safe distance from the wheels to the beet heap.

The side boards are made of straight sheet metal, also in order to minimize damage to beet.

The position of the elevator can be programmed, both the working position and the unloading position. The tankfloors automaticly switch on one by one so that the discharge elevator will not be overloaded.

different engines

The Q-616 is equipped with a 465 horsepower motor with DAF, such as the 617 previously.

The Q 621  features 510 horsepower. Both these engines work at a very low 1100 rpm to 1350 rpm.

The fuel consumption of the last 617 had been brought back to around 30 liters per hour. We expect that this will again be slightly lower. The practice tests will reveal it soon.

several toppers

Not new , but very important to the customer is the choice in toppers. We offer three kind:

1) Integral, which choppes the  leaves and puts it between the rows. (Low maintenance, lightweight and compact).

2) Combi, working integral or with leafspreader (ready for all conditions).

Both the Integral and Combi can be equipped with the new multi-topper scalpers, that are guaranteed to give the best topping result, which nowadays is, taking of the leaf, but not cutting of the head of the beet.

3) Combi with Double Rotor, which has no scalpers and thus saves the entire head of the beet. (latest trend in defoliation but sadly not a good choice in stony areas)

Various cleaning modules

Because there are very many different types of soil, there is a need for large choice in the cleaning system. We have designed the machine in such way that there are four main choices:

- 3 cleaning turbines, one  belt

- 5 cleaning turbines

- 6 cleaning turbines

- 5 cleaning turbines and axial rollerbed

And of course you can also choose the turbine type or gates in all four. Also, the diameter of the turbines has grown 8% , in order to allow an even better flow.

New Electronics / Automation

Of course, the machine is already equipped with all comforts, including:

  • Automatic lubrication,
  • Autom. 4 wheel steering,
  • Autom. Depth control of the harvester
  • Autom. Depth control topper
  • Autom. Tank  Discharge
  • Autom. RPM adjustment of machine functions according to forward speed.
  • Automatic speed adjustment engine when stationary / driving / unloading bunker
  • Auto on and off machine at lowering / raising harvester and topper
  • Reversing direction all machine functions
  • Presets for setting machine to different circumstances.
  • Automatic speed setting (Cruise)
  • Diagnostic system on almost all functions
  • Fuel consumption meter per hectare and per hour
  • capacity meter
  • camera system
  • LED-lighting
  • Automatic speed control of the engine: In neutral, the engine reverts to idle speed, in harvesting mode it goes to the set speed, and while unloading on the heap, it also drops to 1100 rpm.
