Page 22: Working Preparation
Working preparation Hitching to the tractor Hitch the drawbar to the traction bar of the tractor using the pin (A) and cotter pin. In order to make it easier to hitch, use the adjustment of the jack (B). NOTE • The round hole of the tractor hitching must face upwards. •... -
Page 23: Leveling The Dca²
Working preparation Leveling the DCA² After coupling the drawbar, check the horizontal leveling of the spreader. If required, make any adjustment as follows: Consult the tractor's instruction manual and be sure about the possible working positions with the traction bar. Use the height that provides the best leveling of the equipment. Coupling the cardan shaft to the PTO First of all, verify the length of the cardan shaft in the following way: •... -
Page 24: Reducing The Cardan Shaft Length
Working preparation Reducing the cardan shaft length If it is necessary, cut similar parts of the male and female shaft as well as the protection covers. But before cutting the shaft, verify all possibilities of usage without reducing its length. The length adjustment will be done when the distance between the equipment and tractor do not allow coupling. -
Page 25: Tractor Speed
Working preparation Correct assembly of the cardan When assembling the cardan shaft, it is necessary to be careful and leave the terminals on both ends aligned. The discrepancy of the terminals in 90º will cause vibrations and a greater wear on the universal joints, reducing the life cycle of the set. Correct assembly Observe the internal forks alignment... -
Page 26: Pto Rotation
Working preparation PTO rotation Keep the PTO rotation speed constant at 540 rpm. NOTE Consult the tractor manual to check the engine rotation. Final inspection Before filling up the spreader, verify the following points: 1) If the conveyor is adjusted; according to the instructions on page 34. 2) If the belt tension is adjusted properly;... -

Page 29: Position Of Fins At The Discs
Adjustments and operations Position of fins at the discs The rotating discs feature 04 adjustable fins to provide uniformity during the application, both at high and low dosages. The change of the fin angles at the discs provide changes in the application band width and in the direction of the product. - Page 30 Adjustments and operations Distance between distribution bands The distance between distribution bands must be observed to provide a homogeneous distribution in the whole area, so that the same amount can be distributed per m² of soil. In practice, however, a variation of up to 25% in the distribution amount is acceptable and that occurs especially between distribution bands (overlapping band).

Page 31: Gate Opening
Adjustments and operations Gate opening The cover of the gate has the function to limit the amount of product carried by the conveyor. Its activation is made by a thread that allows light movements to open or close the exit. The opening of the gate is indicated on the graduated scale (0 to 15 cm), which has divisions every half centimeter. -
Page 32: Application Tables
Adjustments and operations Application tables The amount of product to be distributed (kg/hectares) takes into account the following points: 1) Tractor speed: 6 to 7 km/h. 2) Rotation speed of the tractor's PTO: 540 RPM. 3) The transmission sprockets combination, which defines the conveyor speed. 4) The opening of the gate, determined by the graduated scale (Check the table). -

Page 36: Conveyor Tension Adjustment
Adjustments and operations Conveyor tension adjustment Before starting to work, check the tension of the conveyor in the following way: • Shut down the tractor engine and PTO. • Under the bin, on its intermediary section, push the conveyor upward and check if there is a clearance of up to 50 mm. -
Page 37: Belt Tension Adjustment
Adjustments and operations Belt tension adjustment To adjust the tension of the transmission belt, proceed as follows: • Loosen the pulley nut (A), along with the internal nut of the tightener (B). • Soon after, adjust the belt tension and retighten the nuts. NOTE Tension allowed = 3.5 cm as shown below. -
Page 38: Changing The Belt Of The Rotating Discs
Adjustments and operations Changing the belt (C-128) of the rotating discs • Loosen the tightener (A) and the pulley nut (B) to remove the belt. Sequence for placing the C-128 belt: 1) Place the belt in the transmission hub (C). 2) Fit the lower part of the belt on the right spreader pulley (D). -
