GrowSmart controls save labor, energy and water ... see Controls link under the Products drop down menu for details Drive train 480 Center drive gear ratio matched to wheel gearbox to produce maximum torque and highest energy efficincyHeavy-duty worm-drive gearboxes for constant speed even on downgradesIn-line drive design between center drive and gearboxes delivers all power to the gearboxes for maximum power distribution and efficiencyA Greenfield pivot with large ag tires can irrigate a 40 acre (16 ha) field in as few as 9 hours.Chemigation/Fertigation Using Greenfield systems to apply chemicals versus traditional methods has several benefits: Reduced application expenses because of less use of ground rigs or aerial applicationsLower cost per acre - Chemical application costs $4/acre for aerial, $2.50/acre for ground rigs, and $0.50 for pivot irrigation. More uniform and precise application with mechanical irrigation, less drift, and less chemical loss. Also nutrients can be carefully regulated.Operator safety - Less human contact with chemical drifts, and less exposure during frequent tank fillings or other tasks because Greenfield systems start and stop automatically.Timeliness and Convenience - Apply chemicals/nutrients at any time, no need to wait for the availability of airplanes for ground rigs.More flexibility with chemical fertilizer than dry. Fewer trips through the field for fewer wheel tracks, and less compaction and crop damage.Less chance of groundwater contamination because less fertilizer is applied at any given time. Applications correspond to maximum crop needs.Some tillage operations may be eliminated, especially if fertilization coincides with the application of herbicides or insecticides. |
