Laser Leveling – Field Operation
Laser leveling requires soil to be shifted from the high points of the field to the low points in the most cost–effective way. In most situations fields will need to be plowed and a topographic survey undertaken before leveling commences.
1. Plough the field.
Plough the field preferably from the center of the field outwards. It is preferable to plough the field when the soil is moist because if the soil is ploughed dry a significant increase in tractor power is required and large clod sizes may result. If the soil is very dry a one-way disc or moldboard may be required. Disc harrows or tine implements are ideal for second workings. All surface residues need to be cut up or removed to aid soil flow from the bucket
2. Topographic survey recording the high and low spots in the field
• A topographic survey using a laser will need to be undertaken to establish the high and low areas in the field.
• A field diagram should be drawn noting the high and low areas in the field. From the surveyed readings the mean height of the field must be established. Taking the sum of all the readings and dividing by the number of readings taken can attain this.
• From the field diagram and knowing
the mean height of the field, a strategy can then be determined to most effectively move soil from the high to low areas..
3. Begin leveling
• The laser-controlled bucket should be positioned at a point that represents the mean height of the field.
• The cutting blade should be set slightly above ground level (1-2cm).
• The tractor should then be driven in a circular direction from the high areas to the lower areas in the field.
• To maximize working efficiency, as soon as the bucket is near filled with soil the operator should turn and drive towards the lower area. 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 leveling pa ss in long runs from the high end of the field to the lower end.
• The field should then be re-surveyed to make sure the desired level of precision has been attained.
• In wet areas where there is poor traction or a chance of bogging the tractor, care needs to be taken to fill the wet areas from the effected edge in a circular motion.
• If the fields are ploughed in lands and leveling undertaken in the areas of soil settlement in the second year, the fields should not require further major leveling works for at least 8 years.
