Its main use is for weeding crops and reducing chemical costs, and may also be used to break up capped soil or as a conventional harrow for seedbed preparation / harrowing. 

FEATURES & BENEFITS

Ultimate contour following ability for uneven ground

 

• Even pressure is applied across every inch of the working width.
• The frame adapts to the ground contours with additional pressure being supplied from the accumulator to even the harrowing pressure across the working width.
• Active harrow bed suspension on the implement frame.
• A flexible harrow bed adapts to ground undulations.

Flexible bed

The flexible design of the tine beds allow them to follow the contours of the land ensuring effective coverage and even tine pressure. Each 1.5m bed has 48 tines spaced at 30mm centres apart and as well as ensuring good tine pressure onto the ground, this design allows it to self-clean as it moves through the sward. 

Spring tines

The oil hardened spring wire has three times the service life of a normal sprung steel wire. 

Adjustable tine angle

Quick and simple tine angle and pressure adjustment, ground conditions will determine how aggressive tine pressure needs to be for effective harrowing. On the OPICO Comb Harrow there are 10 tine angle settings so pressure can be altered, ensuring the vibrating action of the triple coil spring tine can be maximised. 

Construction

The construction of the headstock consists of interlocking pieces of steel so the Comb Harrow doesn't just rely on the welding for strength. The frames and beds are powder-coated and most of the other steel parts are anodised so your harrow will stay in good working order and looking newer for longer.

Hydraulic cylinder with accumulator and hydraulic shut-off valve can be locked for safe road transport.

Folding system

When in transport position, the hydraulic folding models fold up to between 2.5m and 3m depending on the specific Comb Harrow model. This allows easy transportation on the road and through narrow gateways. 

COMB HARROW MODELS

With many options available, creating a bespoke mechanical weeding machine requires technical expertise and know how. The process begins with a farm visit to understand the needs and any issues e.g. crop type, soil type, how the crop is grown, how high tech or low tech a solution is being sought.

After this initial visit a proposal is prepared recommending headstock type, share type, guidance system and other installation options. Once the bespoke specification is agreed, OPICO works closely with the factory to deliver and then install and support the machine.

FEATURES & BENEFITS

Configurations are endless!

• Suitable for combinable, root, salad and specialist crops
• 3m to 18m working widths
• 4 to 72 rows
• Front or rear mounted 
• Fully or semi-mounted
• Manual, mechanical or camera-guided steering 
• Available with seed or fertiliser application equipment

 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
