Dry crop extension

Tailgate

Dry crop extension

The hydraulic folding dry crop extension is standard on PRIMO 351 / 401 / 451 models. The tailgate is also operated hydraulically as standard and can be secured in place for low-clearance building entrances. This reduces the maximum height to 2.66 m.

• Metal profiles are spaced closely together to form the sides of the extension.

• The side crop flow flap is standard.

• Tensioned roof ropes and the rear tarpaulin contain the harvested material while loading and transporting.

• Tailgate opening angle can be adjusted as required from the tractor seat.

• Floodlights for loading chamber and work area available as an option.

Automatic loading optional with dry crop extension

Automatic loading system is controlled by one sensor at the lower end of the front panel and one on the crop flow flap.

Multifunctional tailgate

The tailgate is opened, closed and locked by powerful hydraulic cylinders. No mechanical interlock is required.

The optional tailgate locking system is ideal for low clearances. Using telescopic struts the opening angle of the tailgate can be fixed so it does not exceed the height of the wagon. The tailgate then only lifts upwards to the rear. As a result you can unload the wagon inside low sheds.

Loading chamber

The scraper floor has been lowered at the front by 150 mm to accommodate tyres with a diameter up to 620/40 R 22.5. The forage is pushed upwards as it moves to the rear. This ensures smooth, uniform unloading with a low power requirement. The system is driven by a powerful hydraulic motor and the speed is infinitely variable for perfectly matching the length of your clamp. A two-speed motor is available as an option for driving the scraper floor on PRIMO 401 models and above, which ensures rapid unloading.

High performance with 4 scraper floor chains

The scraper floor is equipped with four chains and the hardened bars are separated and offset. The load chamber floor is constructed of pressure–impregnated, durable wood. The tongue and groove boards are bolted to the frame.

Easy servicing

The greasing points for the front scraper floor shafts are on the side of the wagon.

Unloading

• The full cross-section of the wide opening enables quick unloading.

• The tailgate is opened and closed hydraulically without a mechanical interlock.

• An adjustable tailgate strut is available as an option for unloading in low sheds.

All-steel structure

The steel profile panels are fully enclosed, right to the top. The profiled plates have a special coating to guarantee a long service life. The large surface area of the forage compression flap in connection with the optional automatic loading system ensures the best compression of the crop and maximum use of the loading chamber. The extension bars can be adjusted by 120 mm or 210 mm to lower overall height.

Unloading

Cross conveyor belt

Automatic unloading – just press one button

PRIMO 401 D models feature an automatic unloading system for uniform distribution. A pressure sensor in the beater rotor bearings switches the scraper floor on and off automatically during unloading. The driver no longer has to do this. The beaters are fitted with aggressive tines to unload even highly compressed crop in the shortest possible time.

Cross conveyor belt

The optional cross conveyor belt is 890 mm wide and is powered hydraulically.

• Runs to either the left or right.

• Tailgate locking system.

• Dedicated on-board hydraulics with flowrate of less than 80 l/min.

• Remote control using optional POWER CONTROL Wireless.

Fully enclosed all-steel structure

Bodywork

The steel profile panels are fully enclosed, right to the top. The profiled plates have a special coating to guarantee a long service life. The large surface area of the forage compression flap in connection with the optional automatic loading system ensures the best compression of the crop and maximum use of the loading chamber.

Bodywork options

• H3 floodlight inside loading chamber.

• LED floodlights on front panel and mudguards.

• Video system with monitor and one or two cameras.

• Flashing beacon.

Flexible bodywork

• As an option, the roof ropes can be replaced with metal roof profiles. The strong profiles ensure improved compression of crop material with a low density.

• If you choose this version, we recommend fitting the optional slot-in panel on top of the tailgate as well.

• An extension for the fully-enclosed front panel is also available.

Lower sensor

Upper sensor

The automatic loading system guarantees that the wagon is filled right up to achieve maximum transport capacity. The forage is already carefully compressed in the transfer duct to make full use of the loading chamber.

Sensors mounted in front flap and upper panel section

A sensor at the lower end of the front panel measures the loading pressure for damp, heavy grass and switches the scraper floor on and off accordingly. This prevents disintegration of the forage as a result of too high pressure at the conveyor tines.

The second sensor in the forage compression flap measures the compression inside the loading chamber. The forage is compressed uniformly and the loading chamber filled to the ideal maximum capacity.

Automatic unloading

The automatic unloading system makes life easier for the driver and protects the machine. The tailgate and scraper floor are controlled in sequence. The full cross-section of the wide opening enables quick unloading.

Multifunction tailgate

The tailgate opening angle can be set to different positions from the tractor seat to minimise the effects of crosswinds.
