Grays Slitters & Harrows

Harrows
From furrow to seedbed in one pass
Few moving parts cuts maintenance costs
Faster seedbeds; taking less time, less labour
 
Disc & S-Tine Harrows
Grays "Multi-Harrow" Seedbed Culitivators break most rough ploughed land down to a fine-tilth seedbed in one pass, ready for drilling; saving time, labour and fuel.

To this is added the advantages of less ground compaction from a one pass operation, plus a work rate high enough to help you complete cultivations when the weather and soil conditions are most favourable.

 
4 Operations
Grays "Multi Harrow" Combination Cultivators are designed for the preparation of seedbeds for cereal crops and carry four distinct cultivation toolings within one frame.

Under normal working conditions on most soil types, the operational sequence of this combination breaks down rough ploughed land step by step to a fine tilth, evenly spread over a firm flat seedbed. Tilth depth up to 4" 9100mm)

Disc Tine


S-Tine
S-Tine or Discs
Next in line on the S-Tine models are two rows of spring steel S-Tines which shatter the surface, breaking the furrows into clods and are manufactured in three working widths 8ft (2.44m), 10ft (3.05m) and 13ft (3.96m).

The tines are staggered with sufficient spacing to allow stones and trash to pass through.
On the Disc-type models manufactured in 8ft (2.44m), 10ft (3.05m) and 12ft (3.66m) working widths, two half width rows of heavy-duty concave discs take the place of the s-tines. The discs are 20" (500mm) diameter at 7/ ½" (190mm) centres, running on sealed bearings.

The approach angle of the discs is adjustable to suit varying operating conditions and each disc is fitted with a cleaning scraper. a central duckfoot tine is fitted between the discs to aid soil disposal.

Dutch Harrow
Behind the S-tines or discs is mounted a three-bar Dutch Harrow assembly suspended on a spring-loaded patented parallel linkage, this keeps all three dutch harrow bars parallel to the surface. The front bar of this assembly acts as a levelling bar on clots left by S-tines or discs. Second and third levelling bars are fitted with harrow tines raked towards the rear. The tension on the coil springs controlling the dutch harrow is adjustable to increase or lessen the ground pressure.

Crumble Roller
Finally there is the crumble roller. This acts as a depth control for the whole implement and can be raised or lowered (three positions) to increase or reduce the penetration of the toolings for differering soil conditions. The crumbler compresses the undersoil to leave a firm even seedbed which will retain moisture and ensure fast germination. The crumbler also lifts and aerates the top soil, depositing it as fine tilth on this firm undersurface.

Levelling Bar
At the front end of the implement frame there are two half width spring-loaded Levelling Bars which vibrate across the top of the furrows, to grade the surface and fill up depressions in the field. These bars can be raised or lowered to reduce or increase the grading effect. The spring tension is adjustable.

Tow Bar Kit
A wheel and towbar kit for transporting the Multi-Harrow lengthways is available as an option on the 10,12 and 13ft models.
Levelling Harrow
  
At the lower end of Grays range of cereal seedbed cultivators is the Levelling Harrow. This simple, economically priced cultivator is designed for lighter, more easily worked soils and for the ploughed land which has been broken down by winter frosts - for conditions where there is no need for heavier more complex cultivation equipment. Grays Levelling Harrow has a rigid (adjustable) front levelling bar angled rearwards to grade the soil.
This is followed by a three row harrow, free to rise and fall within the main frame and follow the contours of the ground. The leading bar on this harrow assembly is adjustable, allowing the pitch of the leading tines to be altered to further match the operating conditions. Behind the harrow is a heavy-duty crumbler roller, carrying the weight of the main frame. The weight on this crumbler compresses the undersurface to leave a firm flat seedbed, and lifts and aerates the top soil to provide a fine light covering tilth. maximum depth of tilth is 4" (100m)
 

Slitters

Pasture Slitter
Aeration of grassland helps to prevent slurry run-off, encourages strong root growth, improves fertiliser 'take-up' and generally assists in a wide range of aspects of grassland maintenance.

Grays Pasture Slitter is a rugged, heavy aerating roller, fitted with hardened steel blades which offer clean-cut performance woth prolonged blade-life. Penetration to a depth of up to 7 ½" can be achieved.

 


The drum is water ballasted to enable the operator to vary the depth of penetration. The rotor is land-driven, eliminating the need for expensive drive-trains, reducing operating costs and eliminating the possibility of drive-train failure.

Where further weight is required, this can be added in the form of concrete blocks placed in the built-in weight tray. A mounted rear roller is an option on all three models, and a towing eye is also provided as standard.
Pasture or grassland slitting has always been recognised by turf mainrenance professionals as a beneficial technique for encouraging rice growth. As pressure for enhanced grass yields in agriculture increases, the system is becoming an increasingly important one for farmers too.
