Products / DSL disc harrow
Laumetris Ltd. produces trailed and suspended disc harrows of 3 – 8 m. width for different power tractors. After one drive disc harrow peels soil surface, chops and inserts residuals of plants with weed seeds. Back placed roller compacts soil and improves top surface’s capillary irrigation – stimulates better decomposition of plants residuals and weed seeds, later on it increases better sprout of seeded crop.
Disc harrow DSL is created for stubble razor after harvesting and soil cultivation after ploughing. First line consists of wide spring tines with collating and crumbling claws. In addition 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. Innovative X-concept layout now available on all models. Results of this concept astonishes. In front lane half of the discs are positioned to apposite direction than the other half of discs. Intersection is the middle and during work disc harrow receives even resistance force - this highly increases stability and steadyness of the cultivator. Space between two lanes of discs is expanded up to 1050 mm., so it becomes one of the biggest space in such aggregate class and decreases clogging even in heavy conditions.
Rollers in the back of disc harrow are mounted in few sections attached by hydraulic cylinder to main frame. Such system provides easy depth managing from tractor's cabin. Furthermore, while working at the end of land, all aggregate can be lifted from the ground and turned around moving on rollers. 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. Moreover, rollers diameter is 700 mm., because of big diameter rollers do not spoil structure of soil - linear speed is low.
Double spring roller comes with increased support base is as well lighter and has better cleaning quality. New VT-REX discs are waved and ultra sharp. Clogging-free because of waved properties and improved chopping. Sharpness is a thing that this disc does not loose even over wear time.
