Grays - Disc & S-Tine Harrows
From Grays - Slitters & 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.

Product Details
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.
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.
