Laumetris manufacture trailed harrows with arrow type coulters for hard and soft soil. Coulters cut top layer soil surface. The spring tines help to clear itself and protect coulters against rocks. Specially engineered gaps assist when soil is wet and stubble never sticks. In addition, the coulter arrangement cut soil surface evenly and to accurate depth – subverting weed roots and mix it.
Uses easy-to-change coulters – it takes less than 20 minutes to change all coulters. Working depth is regulated with helix from 50 – 200 mm. Discs chop, mix and turn over all cut top layer of soil. Sections of disc are positioned in angle in 2 rows and it completely finishes harrow’s work. Discs are made steel resistant to abrasion, diameter is 450 mm. and 4 mm. thickness. Working depth is regulated with helix. Backed rollers crumble clods, compact soil and level soil surface. Rollers are chosen according to soil state, it can be stick, cage, ring or cambridge type. |

Disc Harrows
After one drive the disc harrow peels soil surface, chops and inserts residuals of plants with weed seeds. The back placed roller compacts soil and improves top surface’s capillary irrigation – stimulatating better decomposition of plants residuals and weed seeds, and increases better sprout of seeded crops.
The Laumetris disc harrow DSL is created for stubble razor after harvesting and soil cultivation after ploughing. The first line consists of wide spring tines with collating and crumbling claws. This system can be managed from tractor through hydraulic system. 510 mm. diameter discs attached to spring tines while moved in vertical plane do not get stuck or clogged by stubble, other weeds residuals. Space between two lanes of discs is expanded up to 1050mm, decreasing clogging even in heavy conditions.
Rollers in the back of the disc harrow are mounted on sections attached by hydraulic cylinder to the main frame. This system provides easy depth management from the tractor's cabin. Furthermore, while working at the edge of land, all aggregate can be lifted from the ground and turned around moving on rollers.
The rollers hydraulic system works also as protection when obstacles are met - one roller section lifts while contacting an obstacle, when passed roller comes back. Such hydraulic protection system minimizes damage and improves durability. Rollers diameter of 700 mm do not spoil the structure of soil due to a low linear speed.

Heavy Disc Harrows
Soil preparation, where exists many residuals of plants, is very important for generous crop yield. The best preparation can be performed with heavy disc harrow, which inserts weed seeds with residuals of plants, cultivates soil and prepares it for seeding. This aggregate is for hoeing; lying waste, old grass, clover fields and sward of meadows cutting and destroying before and after ploughing; peeling stubble; weeds demolishing, residuals of plants, organic and mineral fertilizer insertion.
Special angle of sections with discs lets to insert residuals and mix it with top layer of soil. Back rollers crumble clods, compact soil and level it. Rollers are chosen from stick, ring or disc type rollers. Sections’ discs are 8 mm. thickness and resistant to wane. In addition, it has unique interdependent pressure system – does not allow discs to over spin and loosen. Moreover, high-level bearings are used for its great sealing. Axes are made from special hardened steel.

The Laumetris LLA is a trailed heavy duty disc harrow, with an optional depth of up to 150mm. It has 4 sections, a disc diamter of 660mm and a roller diameter of 500mm.
