Interrow Cultivator

Interrow Cultivator

Interrow Cultivator

OPICO interrow cultivators are designed to accurately hoe between rows of growing crops to cut off the weeds just below the surface.
Almost any crop with adequate space between the rows can be tackled. Interrow cultivators are fully adjustable and configured to suit any row width or combination of row widths. Front or rear-mounted versions are available, along with trailed semi-mounted versions.

Bespoke Tube Profile

Hatzenbichler’s bespoke tube profile and locking mechanism ensures machines can be configured as required and all components are locked in position.

Heavy Duty Parallelograms

Parallelogram mounting frames for the hoe carriers maintain pre-set working angles and pressure whilst allowing accurate ground contour following.

Different numbers of shares are fitted to the hoe carriers depending on row widths and crop types, for example in cereal crops 3 rows are hoed per carrier with a minimum row spacing of 12.5cm.

  • Box section parallelograms
  • No twisting in work
  • Bushed pivots
  • Greased adjustable depth wheels

Camera Guidance

 

Guidance Headstock

The objective of camera steering is for mechanical weeding to be more accurate, efficient and easier for the operator. It requires a
precisely engineered headstock for exact movement control, allowing the operator to work more effectively at higher working
speeds. Camera guided machines can be operated much closer to the plant rows and hence provide improved weed control.

The versatile Hatzenbichler headstock has an integrated hydraulic ram (1) to provide up to 250mm of side-shift in either direction, allowing accurate compensation for deviations caused by side-slopes, as well as errors due to drilling or driving accuracy.

A potentiometer (2) monitors movement to ensure precise positioning. Oil is sent to either left or right by the camera controller, ensuring the hoe shares run as close to the crop rows as possible without damaging the crop. As you would expect parallel side shift rails (3) are greased and bushed.

Three options of headstock are available from lightweight 450kg to heavyweight 1300kg for cultivators over 12m (see back page for headstock details).

Steel Flange Wheel

Moving the hoe shares sideways to follow plant rows creates powerful lateral forces.

If side forces exceed grip from the tractor’s rear wheels, then the tractor could be moved sideways leaving the hoe position unchanged resulting in damage to the crop.

To prevent this, the headstock has a pair of large diameter flanged steel wheels which anchor the guidance headstock in line behind the tractor wheels. Thereby withstanding the side forces for perfect row following.

This is particularly the case with wider working widths, or when the hoe shares are working deep.

 

 

 

 

 

Spot Spraying

The camera software developed by Tillet and Hague allows for the addition of spot spraying technology to be attached to the cultivator if required.

Tillett and Hague are world leaders in the development of vision guidance and control technology for field scale precision crop protection, whether mechanical, chemical or biological.

Models

Combinable Crops

The Hatzenbichler range of rigid and hydraulic folding combinable crop interrow cultivators are available in 3 – 18m working widths. Row widths down to 12.5cm can be cultivated.

The machines can be mounted to the front or rear of the tractor. The hoe carrier is fitted as standard with Vibro-tines and duck foot shares.

  • 3m to 18m
  • Front or rear mounted
  • 1, 3 or 5 section frame
  • 1 or 3 tines/parallelogram
  • 12.5cm row spacing upwards
  • Vibro-tine with duck foot share

Sugar Beet

The Hatzenbichler range of rigid or hydraulic folding sugar-beet interrow cultivators are available in 3 – 12m working widths. Row widths can be set between 35cm and 50cm.

The machines can be mounted to the front or rear of the tractor. The hoe carrier is fitted as standard with Vibro-tines and duck foot shares.

  • 3m to 12m
  • Front or rear mounted
  • 1, 3 or 5 section frame
  • 3 tines/parallelogram
  • 35cm to 50cm spacing
  • Vibro-tine with duck foot share

Maize

The Hatzenbichler range of rigid or hydraulic folding maize interrow cultivators are available in 3m to 12m working widths. Row widths can be set from 50cm upwards.

The machine can be mounted to the front or rear of the tractor. The hoe carrier is fitted as standard with S-tines and A shares at 150mm wide and half shares at 85mm wide.

The maize interrow cultivator is designed to hoe the weeds and/or bury them depending on growth stage.

  • 3m to 12m
  • Front or rear mounted
  • 1, 3 or 5 section frame
  • 3 or 5 tines/parallelogram
  • 50cm row spacing upwards
  • S-tine with A share

Options

Kress Finger Weeders

Optional rubber Kress finger weeders can be attached to the hoe carrier and are used to weed in between the plants. Rubber fingers grip and pull out the weed from the side and can reach the weeds where the hoe cannot.

For maximum effect, finger weeders should be used as the weeds emerge. They have a working depth of between 2cm and 4cm and are suitable for rows of 25cm upwards. There are different sizes of rubber fingers to choose from depending on row width.

Row Harrow

A tined harrow can be fitted to weed along the row and level soil.

Crop Protectors

Optional plant protector discs or crop guards can be attached to the hoe carrier to shield the young plant from smothering.

Isobus Section Control

To bring an extra level of precision there’s also the option of ISOBUS controlled sprayer-style GPS section control.

With individual hydraulic rams on each parallelogram linkage, the Muller ISOBUS controller is able to lift
individual row units as they reach previously cultivated ground.

This is a particular benefit when working in fields with angled headlands – the system is able to detect when the hoe shares are reaching the end of the run and automatically lift them out of work to avoid hooking out plants on the cross-drilled headland bouts.

Technical Specification

Technical Specification

When specifying an interrow cultivator there are many things to consider. Working width, row width and crop type determine the basic configuration but there are multiple options to look at after that. Please speak to your local dealer and request a visit from an OPICO Territory Manager.
