Maximum cost efficient In today s economic environment, farmers need the most cost effective machinery. For years and years large farmers around the world have been convinced of the principle of high speed application combined with low volume spraying. Several agricultural studies have proven that this technique works. Better chemical coverage of the crop, less chemical on the ground means tremendous improvement of spraying quality, but at the same time an enormous increase of capacity. Higher speed, better coverage Weed, insects and crop diseases don t wait for the optimal spray conditions. They often thrive when field conditions are at their worst. You can t afford to miss the opportunity. Higher application speeds while spraying give a different coverage of chemicals on the crop in comparison to spraying at lower speeds. The droplets are being thrown at higher speeds at the crop, resulting in an other angle of impact into the crop. A better crop coverage of the chemicals, and less chemical on the soil. A better spraying result is a logical consequence of using lower volumes, not because of the reduced amount of water, but the concentration and coverage are crucial factors of the spray result. More capacity without making concessions to your principles. Excellent spraying results, low ground pressure, less fuel consumption, less working hours, that s how you can increase your profits! Spra-Coupe 7460 and 7660 maintains its world lead in innovative design and superior performance and continues to be the leading self propelled high clearance sprayer on the market. 2
SPRa-coupe 7460/7660 How the high speed is achieved A combination of relatively light weight, superb suspension, plenty of power and torque puts Spra-Coupe ahead of conventional sprayers. The light weight means that soil compaction is minimized and damage to fragile top soil is reduced. Independent front and rear suspension and the flex frame give the Spra-Coupe agility and stability in the field. The chassis design has proved to be very durable. More ground cover Most large self propelled and big pull type Sprayers work at around 10-12 km/h and cover around 100 hectares a day. The Spra-Coupe can work at around 20-25 km/h and cover twice that area with ease. But of course it is still possible to use the Spra-Coupe in a conventional way. More Power Fitted with powerful Caterpillar Tier 3 / Stage IIIA engine the machine has a great capacity in flat and hilly areas. Through the mechanical drive line the machine has less power loss. The powerful engine combined with the mechanical drive line improves performance and reduces fuel consumption. The Spra-Coupe 7460 and 7660 are fitted with Powershift transmissions with 6 gears forward and 2 gears reverse. The power shift transmission with cruise control allows the operator to concentrate on the job, as the machine automatically returns to its working speed after headland turns. 3
Perfect environment Operator environment Fitted with a highly comfortable, fully air suspended, panoramic, air conditioned cab, you can be guaranteed an excellent level of operator comfort. There are a number of overhead switches, controls, cab lighting, standard airco/ heating and radio / CD player. Joystick The floating armrest allows the operator to perform a number of functions. The Joystick, integrated in the floating armrest allows operation of gear shifting, spray pump, booms, sections, cruise control, foam marker and auto guide and system functions with the simple push of a button. Adjustable track width The adjustable front and rear track width allows the operator to change the track width on the drive by simple push of a shifter in the cab.

SPRa-coupe 7460/7660 Aluminum booms Booms from 24, 28, 30 and 36m are available for the Spra-Coupe 7000 Series. Aluminum booms are light weight and are exceptional rigid and stable with full breakaway, this feature extends boom life and improves machine reliability. High clearance The outstanding ground clearance of up to 122cm on 7660 and 106cm on 7460 Spra-Coupe models offers a tremendous reduction in crop damage, particularly in sensitive crops such as oilseed rape. Spray pump A hydraulic driven centrifugal pump gives 322 litre per minute. The pump gives constantly the required volume. There is a low maintenance requirement. 5
Perfect environment Spray controller Fitted with the Raven 5000 spray control system. The Can- Bus spray controller controls constantly the application rates. The system monitors the litres per ha, the spray pressure, total sprayed volumes and area covered, speed and tank volume. Maintenance and service Designed for low maintenance and reduced down time. The machines have a low number of grease points and the front tilting bonnet ensure full access to major parts in minutes.
