Description

Dewulf's 2-row self-propelled, off set harvester with elevator.
Equipped with 3 hydraulic driven sieving webs, the Dewulf R4060 provides small drops and excellent sieving capacity. The advantage of the hydraulic driven webs is that the direction and speed of all webs are adjustable depending on the field conditions.
The R4060 comes standard equipped with a front mounted, modern haulm separator manufactured from wear-resistant Hardox steel and equipped with depth control and side-shift. This results in perfect positioning along the ridges and optimal removal of the haulm, even in the curves. The depth can be adjusted automatically from the cabin.

R4060 adapt the technique of offset harvesting, which makes sure that the ridges are not compressed and the soil can be sieved much better. With the combination of speed adjustable agitators in the web(s) a great sieving result will be achieved. Agitators can also be switched on/off from the cabin.

From the 3rd sieving web the product is transported onto the lower hedgehog belt which breaks up the large clods before they reach the axial module. This result in great sieving capacity
The wide open and foldable elevator fills smoothly the trailer. In this way, quality losses are reduced to a minimum.

Stability of the machine is an important aspect regarding the intake of the product. Too much balancing of the machine can have a negative effect on this. Large wheels ensures an optimal stability and ground clearance in the field. In combination with a balanced weight distribution, low ground pressure is obtained.

The robust mono chassis guarantees a superior durability with a low weight. The open construction provides a considerably improved view of the harvesting process.

Standard you have an easily and quick access to all main components in order to do the proper maintenance. Beside of that Dewulf's machines are equipped with standard parts which are worldwide easily available.

Dewulf R4060 creates an ergonomic way of working, which enables the operator to work in a friendly environment, in order to optimize the harvesting quality, even during long days of working.
The new control unit via the ergonomic joystick, (which is very comfortable in the hand and easy to operate) harvesting display and traction display allow the driver to operate the machine easily and comfortably.
All controls have been placed close to the operator to allow easy and convenient operation.
There are pedals to operate the rear steering and levelling of the machine. In the cabin, the entire product flow can be monitored using the cameras and colour monitor(s).


Unique points:
- Possibility to be adapted to all kind of field circumstances
- High capacity
- Strong and open chassis
- Proven and tested worldwide
- Professional control system for drive (DCU) and harvesting (HCU) control with user friendly joystick
- Maintenance-free components
- Standard spare parts, worldwide available
- Fully hydraulic control
- Large wheels, which guarantees drive ability in all conditions
- Very manoeuverable machine
- Haulm roller between 2nd and 3rd web
- 1 Hedgehog belt with adjustable speed and inclination, as an additional cleaning
- Cleaning module: axial rollers with speed and angle adjustment
- Making use of the advantage; that product is first passing over the wide lower hedgehog belt which breaks up the large clods before they reach the axial rollers. This result in great sieving capacity
- Different, interchangeable cleaning module possibilities (Easy Clean module and/or web module)

Machine is standard equipped with:
- Cabine: CLAAS: windscreen wipers, radio, Grammer pneumatic seat, adjustable steering wheel, 2 adjustable and heated wing mirrors. An extra frame is added at the right side of the driver where extra equipment can be added (GPS, cell phone holder, ... )
- Air conditioning with adjustable ventilators
- Operating system: DCU and HCU [drive control-unit (DCU) on the top to set the adjustments of the drive functions; harvesting control-unit (HCU) on the bottom to set the adjustments of the harvesting functions] + user friendly joystick + 20 quick acces buttons to go directly into the mostly used functions. 5 different pre-set can be adjusted: this makes it possible to set all the harvesting parameters during harvest with just 1 push on the joystick
- Diesel engine SCANIA DC9 85A 257 KW (350 HP) Tier IV Final (ad blue) with cooler (water / air / oil); rpm on the road: 1.300, rpm in the field: 1.600

- Hydrostatic 3-wheel drive continuously variable (0-20 to 30 km/h depending on local regulations), 5 gears  of which 4 freely adjustable in the DCU. The traction can be adjusted per wheel, so that you can keep harvesting even in the worst circumstances and weather conditions. You can also choose to harvest in automatic gear.
- Automatic greasing system
- Machine inclination = automatic levelling + manual operation with control pedals
- Haulm topper (2 row) with side removal to the right side. Rotor with ridge shaped flails. The haulm chopper is connected to the frame of the front wheel with side-shift option so that the haulm topper gives the best results even in curved fields. ADC (Automatic Depth Control) with 2 skids makes sure a perfect pulverization. The hood of the haulm topper is made out of durable material.

- Axial module: 18 Rollers, speed and inclination (12,5°) adjustable from the cabin, has an anti blocking system. Quickly interchangeable with optional sieving module, easy-clean module or other specific module. Configuration axial module: spiral roller = rubber Ø 90 (high pitch); smooth roller = rubber Ø 82
- Cross conveyor after the cleaning unit. This conveyor brings the potatoes into the discharge elevator. Width 800mm, length 2.505mm.
- Discharge elevator: width 1.200 mm, with flights and extra large drive sprockets. The discharge elevator can put the crop between the ridges to open the field.
