Multi-Seeder

The HE-VA Multi-Seeder and Multi-Seeder Twin have been developed to work in combination with HE-VA cultivation and grassland machinery. Whilst the seeders themselves ensure precise seed rates, simple calibration and simple to use controls, the fitting kits that HE-VA have developed allow easy, safe access and provide for all seed placement requirements.

• Mechanical or GPS electronic drive

• Pneumatic distribution via electric or hydraulic fan

• Individual metering for each outlet - precision

• Six seed rollers available, coarse and fine rollers supplied as standard*

• RDS control for simple calibration and rate setting (EL models)

• In cab variable rate control through RDS control system (Elec models only)

• Double spreading plates for precise placement and distribution

• Inspection window for seed level monitoring & low level sensor alarm

• Manual shut off switch

• Hydraulic and Electric fan malfunction alarm

• Agitator

• Calibration tray supplied

• ISOBUS, iSOCAN Artemis control, is standard on Twin Multi-Seeders, and an option on the single hopper Multi-Seeder

A selection of different seed rollers ensures that on a 3m Grass Rejuvenator the Multi-Seeder achieves an even spread pattern for grass reseeding. Similarly band seeding of Oilseed Rape at an ultra low seed rate can be achieved on a Subsoiler. Furthermore the Twin Multi-Seeder allows a single control box to be used for OSR seed and slug pellet or fertiliser application at the same time.

Available as standard with twin electric fans, or as a Pro version with a hydraulic fan for increased air flow when used on wider implements and more demanding situations.

Multi-Seeders supplied with an Evolution or Subsoiler & Stealth models are supplied with a single fine roller.

HE-VA offer complete Multi-Seeder mounting kits for:

Tip Roller, Tip Roller XL, Grass Roller, King Roller, Disc Roller Contour, Disc Roller XL Contour, Combi-Disc, Triple-Tiller, Subsoiler and Stealth. Mounting kits are supplied as standard with the Grass Rejuvenator and Evolution.

The Multi-Seeder can be supplied with a single or twin metering system, the twin model allows a single control box to be used for OSR seed and slug pellet or fertiliser application at the same time.

A selection of different seed rollers ensure that whatever the application requirements e.g. even spread (grass seed), band seeding at ultra low rate (OSR) the correct rate can be achieved. The seed rollers available are as follows: grain/fertiliser seed roller, coarse seed roller, medium seed roller, fine seed roller, large hollow seed roller and small hollow seed roller. Furthermore, the Twin Multi-Seeder allows a single control box to control both hoppers independently e.g. OSR and slug pellets or fertiliser at the same time at different rates.

Fine and coarse seed rollers are supplied as standard. A single fine roller is supplied with the Multi-Seeder for the Evolution, Subsoiler and Stealth. 

There are 8 or 12 seed outlets as standard but it is possible to blank off a number of them using the Blanking Roller and Stop Kit, for example for applying seed in a band behind a five-leg subsoiler with one outlet per leg, running directly in-line with each leg.

The Multi-Seeder can be used for either band application (recommended for OSR) or to spread seed evenly across the whole width.

The standard broadcasting outlets spread the seed in a overlapping pattern for an even full width coverage. Alternatively modified outlets are used for band application of seed into rows. The seed placement is adjusted by changing the height of the distribution outlet, this will give you wider or narrower bands.

The amount of seed applied is controlled by the speed of the metering roller, this is adjusted until the desired application rate is achieved.

The control box in the cab allows setting and adjustment on the move.	Calibration is performed by removing the metering roller cover and using a calibration tray.

Forward speed control, i.e. seed roller metering, can be mechanically driven for the Grass Rejuvenator Multi-Seeder, or on all other Multi-Seeder models, controlled by GPS and driven by electric motor (EL). Pneumatic distribution is either via electric fan or, by hydraulic fan on all Pro models.

ISOBUS interface on tractor terminal

The Multi-Seeder comes with radar to give constant forward speed related metering.

On some tractors it is possible to connect to the tractors own radar system. Forward speed related metering means accurately maintained application rates on high draft machines and in awkwardly shaped fields where ground speed may vary.

If a mechanical driven model is chosen then a land wheel & cable system are used giving accurate forward speed related metering

The Multi-Seeder is supplied with a strong mounting plate which assist fitting to whatever cultivation machine is chosen. The hopper and chassis are built to withstand the rigors of high speed seeding in arduous conditions.

Three simple steps to mounting your Multi-Seeder for ideal seed placement:

Step 1 - Hopper positioning
The Multi-Seeder Hopper can be mounted anywhere but it is important to ensure that the pipes to the outlets are not too long and that the seed always flows downhill.

Practicalities of calibration and filling the hopper should always be considered when mounting the hopper. A simple base plate is provided to bolt or weld onto the implement, the Variocast can then be mounted onto this and removed if necessary.

Step 2 - Radar
Multi-Seeder's are capable of metering to within 0.1Kg/ha if required which is critically important with expensive small seeds. The radar is an important part of this accurate metering and should be mounted out of the way of soil flow from the cultivator where it can follow the contours of the land.

The radar needs to be mounted at 45 degrees from horizontal and the sensor should ideally be mounted between 60cm and 90cm above the ground to ensure an accurate reading of the forward speed. A radar cutout switch may be needed to cut off reading when turning on the headlands.

Step 3 - Outlets
Positioning the outlets correctly is critical for good seed placement. With most applications, the outlets should be mounted just behind the cultivation elements and in front of the press roller.

Where possible some adjustment should be designed into the mounting of the outlets to allow fine tuning of the seed placement in the field. The optional 1.5m or 2m distributor holders assist mounting the outlets and allow horizontal and vertical adjustment to alter the spread pattern.

The HE-VA Multi-Seeder 8 incorporates a mechanical motor driving the metering roller. Application seed rates can be altered manually from the RDS control box in the cab, to ensure accuracy. Oilseed Rape seed rates or rather seed numbers per square metre are critical to control cost and maximise yield and the Multi-Seeder allows unmatched precision whilst also monitoring the seed levels and work rates for the operator.

The HE-VA Multi-Seeder 8 EL incorporates a variable speed electric motor driving the metering roller. This allows infinitely variable seed rates to be controlled and altered from the RDS control box in the cab to ensure accuracy. Oilseed Rape seed rates or rather seed numbers per square metre are critical to control cost and maximise yield and the Multi-Seeder allows unmatched precision whilst also monitoring the seed levels and work rates for the operator.

The Multi-Seeder 8 Pro EL OSR seeder incorporates all the features of the standard Multi-Seeder but has the added extra of a hydraulic fan.

The hydraulic fan is ideal if you require more air flow due to one of the following reasons: 
1) The seeder needs mounting a long way from the seed application point requiring seed hoses larger than 4m.
2) Where dividers are required to achieve 10 or more outlets.
3) Especially high seed rates or forward speeds are required.
4) Working widths above 6.5m are required
