GRASS HARROW

OPICO Grass Harrow working width icon, 1.5m - 27m

The OPICO grass harrowing concept simply transforms the way you work your grass.
The angle of the tine combined with the overall design of the harrow makes it ideal for stimulating new grass or renovating old pastures.

With an OPICO Grass Harrow, leys can be re-vitalised and dry matter yields boosted. You can attach an Stocks ag seeder and oversow old worn leys to boost grass and clover content, or start afresh and put down a brand new ley with the harrow and seeder combination.

The OPICO Grass Harrow covers every inch of the ground, thanks to its unique contour flexing tine bed. It clears moss, opens the surface, improves aeration and encourages growth. Like all good ideas it is very simple and is now recommended by thousands of farmers who have switched to this common-sense approach to what used to be a ‘harrowing’ job.

FEATURES & BENEFITS

The OPICO Grass Harrow has revolutionised grass harrowing: larger working widths, more adjustment and aggressive spring tines mean that a better job can be achieved faster and at a lower cost.

With typical working speeds of 4½mph to 7mph the Grass Harrow is a high capacity machine. For example a 6m machine is more than capable of covering over 100 acres in a normal working day.


 

THE RANGE

Working widths range from a very handy 1.5m to 12.4m. There are rigid and hydraulic folding units with a choice of 7mm or 8mm tines.

The machines are designed for strength without the need for high horsepower and are equipped with a fully adjustable depth wheel, which works alongside the tine angle settings for maximum effectiveness. The hydraulic folding models have a single acting ram that allows the grass harrow to be folded and unfolded from the tractor seat.

FLEXIBLE BED

Grass harrow flexible bed

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


 

ADJUSTABLE TINE ANGLE

Grass harrow tine adjustment

Ground conditions will determine how aggressive the tine pressure needs to be for effective harrowing. With 10 clear tine angle settings, pressure and tine angle can easily be adjusted. This ensures the oscillating action of the triple coil spring tine can be maximised across the whole working width.

SPRING TINES

Grass harrow spring tines

The Grass Harrow’s 7 or 8mm spring tines are able to penetrate even the hardest of ground, ripping out dead thatch and opening up the soil surface allowing air into the root zone to stimulate growth. The oil hardened sprung wire has three times the service life of normal sprung steel wire and channel mounting of the tine coil prevents damage to the growing tip and leaf of the grass.


 

CONSTRUCTION

Grass harrow frame

The construction of the headstock consists of interlocking pieces of steel so the Grass Harrow doesn’t just rely on the welding for strength. The frames and beds are powder-coated. Most of the other steel components are anodised so the harrow will stay in good working order and look newer for longer.

FOLDING SYSTEM

Grass harrow folding system

When in transport position, the hydraulic folding models fold to between 2.5m and 3m dependent on the model of grass harrow. This allows easy transportation on the road and through narrow gateways.


 

HYDRAULIC CYLINDER

Hydraulic cylinder with lock to ensure safety during road transport.

SUPPORT WHEEL

Height adjustable support wheels are used in conjunction with the tine angle when setting the aggression and pressure required on the harrow tines to ensure the correct amount of pressure is applied.


 

FAN JET PRO

The Fan Jet range of applicators are cost effective and multi-purpose. Product is either gravity fed or metered onto a spinning disc for broadcast application.

The Fan Jet Pro can be fitted to an OPICO Grass Harrow for the straightforward broadcasting of grass seed, clover and other small seed mixes. Seed is gravity fed onto a spinning disc, providing an even spread pattern. A seed deflector kit is recommended to direct seed into the harrow.

SLUG PELLETS, SEEDS & GRANULES

When mounted to a grass harrow, the Fan Jet Pro offers working widths from 3m to 6m. It is simple to set up and use, with fixed or optional variable disc speed.

CONTROL OPTIONS

( Subject to machine or model within the range )

TURBO JET

The Fan Jet range of applicators fast & accurate application of small seeds and granules. Available as an 8 outlet (Turbo Jet 8) or 10 outlet (Turbo Jet 10) applicator, the Turbo Jet can deliver product up to 15m working width.

FAST & ACURATE APPLICATION

It can also be set up with some outlets either blanked-off or doubled as necessary depending on application and working width requirement.


 

GRASS HARROW MODELS

1.5m - 3.0m Non-Folding Grass Harrows

4.5m - 8.0m Hydraulic-Folding Grass Harrows

The hydraulic-folding models consist of 7 widths, 4.5m, 5m, two 6m versions, 6.4m, 7.5m and 8m.

The 6m comes in two different formats, one unit has 3x2m sections the other has 4x1.5m sections. The 3 section unit is able to fold down to 2.5m for transport which enables easier movement through narrow gateways and down the road. On the other hand the 4 section unit folds to 3m for transport but has improved contour following ability in the field.
