Laser Guided Land Leveler Laser Star Benefits of Laser Guided Land Leveling As per studies, a significant (25 - 30%) amount of irrigation water is lost during its application at the farm due to poor farm designing and unevenness of the fields. Fields that are not level, have uneven crop stands, increased weed burden and uneven maturing of crops. All these factors lead to reduced yield & poor grain quality. Farmers also recognize this and therefore devote considerable time & resources in leveling their fields properly. Laser guided land leveling makes leveling process eas y, faster and cheaper. 1. 25-30% saving of water. Saving Water Is Like Money 2. Land saving - no need to make bunds & channels for irrigation. 3. Increases yields by 10 -15% due to even crop stands & full land utilisation. 4. Energy saving due to less requirement of water and tractor time for levelling 5. Improvement in nutrient use efficiencies 6. Weed Control, Labour saving, Time saving, Land saving etc. How Laser Leveller Works ? The laser-controlled system requires a laser transmitter, a laser receiver, survey receiver, an electrical control panel and a twin hydraulic control valve. The laser transmitter transmits a rotating laser beam, which is used as the reference datum by the laser receiver mounted on the levelling bucket. The control panel mounted on the tractor interprets the signal from the receiver and opens or closes the hydraulic control valve, which raises or lowers the bucket.Levelling requires soil to be shifted from the high points of the field to the low points in the most cost effective way. Fields need to be ploughed and a topographic survey undertaken before levelling commences. Steps Top Plough the field. Use rotary tillers, disc harrows or cultivators as appropriate. Remove all surface residues / roots etc so as to aid soil flow from the bucket. Conduct a topographic survey to record the high and low spots in the field. From the surveyed readings establish the mean height of the field by taking the sum of all the readings and dividing by the number of readings taken. Then using a field diagram and the mean height of the field &determine a strategy to effectively move soil from the high to low areas. Position the laser-controlled bucket at a point that represents the mean height of the field. Set the cutting blade slightly above ground level (1-2 cm). Drive the tractor in a circular direction from the high areas to the lower areas in the field. Laser leveller controller automatically raises or lower bucket scraper as required .However during initial levelling it may sometimes be necessary to move away from circular path and turn the tractor towards lower area of the field, as soon as the bucket is near filled with soil. Similarly as soon as the bucket is near empty the tractor should be turned and driven back to the higher areas. When the whole field has been covered in this circular manner, the tractor and bucket should then do a final levelling pass in long runs from the high end of the field to the lower end. The field should then be re-surveyed to make sure that the desired level of precision has been attained. In wet areas where there is a poor traction or a chance of bogging the tractor, care needs to be taken to fill the wet areas in a circular motion. log on to www.aslasers.com for more details and specifications
