5 - BaLLaStinG tHe tRactoR’S fRont

Working with an implement installed in the three-point hydraulic system, as is the case of system of JM36�0SH, it is absolutely natural for the tractor’s front, in given circumstances, to tend to lift off the ground. To compensate this tendency, you must ballast the tractor’s front, preferably using the already existing support and original ballasts. Do not place weights on the front wheels. A practical way of determining the amount of ballasts is as follows:

Without the coupled implement, weigh on a scale only the tractor front axle. After coupling the implement, put it in transport position (fully lifted by the hydraulic system) and weigh the front axle again. Install the necessary number of weights to obtain at least over half of the initial weight.

This procedure is essential to guarantee good drivability of the tractor, facilitating following of the line and preventing the implement from leaving failures.

The placing of frontal weights does not always keep the tractor properly balanced, especially if driven too fast on an uneven terrain and with the implement in transport position. Be prudent and drive slowly, especially under such conditions.

To interlock, choose the most plane location possible.Maneuver the tractor slowly in reverse gear toward the implement,

always ready to press the brakes. When coming close, use the lever to control the hydraulic position, leaving the lower left arm level with the implement’s coupling pin (looking from behind the tractor). Proceed as follows:

�) Interlock the lower left arm and place the lock pin.�) Interlock the upper arm (3rd point) and place the lock pin.3) Finally, interlock the lower right arm, using the leveling knob to lower

or raise the arm or the 3rd point extender thread to bring the implement near or far.

7 - LeVeLinG

For a perfect operation, the JM3620SH must be level in both directions. Level using the 3rd point arm and knob of the tractor’s right lower arm, such that when looking from the side and back, the lower line of the front pipe of the implement is horizontal.

After leveling, you must adjust the stabilizers so as to remove the gap between the implement and tractor. This procedure is essential to assure stability and quick response of the implement to the tractor’s movements. Proceed as follows:

�) Lift the implement completely;�) Try to keep an equal distance between the lower arms and tires

from both sides;3) Adjust the stabilizers until all the gap between the implement and

tractor is removed.

Never adjust the stabilizers when the implement is lowered because they may be damaged on lifting them.

drive by diaphragm electropump:

The diaphragm electropump (Flojet QUAD 4300 model) used by JM36�0SH is of the positive displacement and self-priming type. It can be mounted up to 2.4 m above the level of the fluid it will pump normally, provided there is no air inlet at any point of the suction line.

electrical connection

Connect the red wire (+) and black wire (-) of the pump power cable to the respective red and black wires connected to the positive and negative terminals of the tractor battery. Position the on/off switch in a place of easy access on the tractor dashboard. Said switch has a �5A fuse to protect the pump from a possible short circuit in the tractor electric system.

In addition to this manual, you also received a specific manual on the pump and control supplied by the manufacturer. It is very important that you read them for correct use and maintenance, thus obtaining a good performance and long service life of the equipment.

drive by Piston-diaphragm Mechanical Pump:

The piston-diaphragm mechanical pump (Comet BP �0/�5 model) used by the JM3620SH is equipped with a pressure accumulator, whose function is to minimize the intermittence (pulsation) in the sprayer nozzles. Its pressure is determined in function of the pressure range in which the pump will operate, and must be adjusted and checked regularly using a compressed air system and manometer like the one used to calibrate tires, observing the table below.

choosing the Spraying nozzles (tips)

The application equipment has the function of distributing the spraying accurately on the target. However, many factors interfere negatively in the spraying quality, the most important of which are improper calibration of the equipment, lack of control of size and distribution of the sprayed drops, improper volume of application, faulty covering on the target, improper height of the spraying bar, time of application and incorrect choice of the nozzles.

Practical method for calibration

� – Fill the sprayer at least up to half of its capacity;� – Measure and note down the time required for the tractor to cover 50

meters in the gear and acceleration of desired works. Repeat the operation to obtain the average;

3 – Calculate the speed according to equation �;4 – Obtain the following informations:- The type of nozzle used, ensuring that they are all equal;- The volume to be applied (l/ha);- The speed obtained in item 3;- The spacing between nozzles (m);5 – Calculate the quantity (l/min) per nozzle according to equation �;6 – Ensure that the sprayer is free of leaks or clogs and that all the

components are duly mounted and in perfect state;7 – Turn on the sprayer and collect the volume applied in � nozzle for

� minute, adjusting the pressure and repeating collection until the quantity determined by equation � is obtained;

8 – Ensure that the final working pressure is within the admissible range for the type of nozzle and pump used. Use a larger nozzle if the pressure is too high.

It is very important to read the following information carefully because they give the cautions to be taken when using phytosanitary equipment. This information was generated by Embrapa Sistemas de Produção and can be obtained at the website http://sistemasdeproducao.cnptia.embrapa.br/

calibrating the Sprayer

Calibration is fundamental for correct application of pesticides. Once the sprayer has been coupled and supplied with water, check the system’s operation, if there are no leakages, and if the components are functioning satisfactorily.

Equipping the sprayer with appropriate nozzles is one of the most crucial points in this phase. The sprayer must be taken up to the worksite and several nozzle options must be tested to decide on the one that best meets the treatment requisites, that is, the one that best places the product on the target, without loss by run off by drifting.

The components of the equipments to be considered to improve quality and efficiency in the phytosanitary treatments are as follows:

nozzles – preferably use ceramic nozzles, due to the greater resistance, durability and quality of the drops. It is regarded as the foremost organ of the sprayer because the flow and quality of the drops depend on it. It has an average durability of 400 hours with �50 to �00 pounds of pressure.

filter – use filters in the tank inlets, before the pump and before the nozzles, to prevent wear and/or clogging. The filter at the tank inlet must be cleaned often, at least daily;

agitators – after diluting the products, it is necessary that the syrup remains homogenized during spraying, for uniform distribution of the product on the plant, and the flow must not be greater than 8% of the pump capacity. The agitator is essential when working with products in the form of wettable powder or concentrated suspension;

Manometer – used to check the exit pressure of the syrup through the nozzles. Must have visible scale and be bathed in glycerin for greater resistance. The ordinary manometer has durability problems because it lacks the robustness to support the harsh work conditions (vibration and aggressive liquid circulating in its interior). Excess pressure in the pump causes drifting and loss of the spraying syrup;

��


13 - LUBRication

JM3620SH was designed to require minimal lubrication. However, this is necessary and essential in some parts for good functioning and greater service life of the implement.

Below are the lubrication symbols, recommended lubricant table with the equivalent specification of several manufacturers and indication of lubrication points and intervals.

Before beginning lubrication, clean the grease fittings and replace the damaged ones.13.1 - Lubrication Symbology

Lubricate with lithium soap-based grease, NLGI-� consistence in the recommended intervals.

Lubrication intervals in worked hours

Oil Gage: Check the oil level after the first 10 hours of work, period of the pump’s breaking in and top up if necessary.

This operation must be done with the machine leveled, use ISO VG �50 (SAE 40) oil or equivalent.

Oil Change: Change the oil after 300 hours of work.

The pump’s oil gage must be checked periodically, and must not be below the level mark, if necessary, top up with ISO VG 50 (SAE 40) mineral oil. If oil leaks from the pump, it must be repaired immediately to prevent damages to the internal components. The pump must not work with rotation greater than 540 rpm and also, it must not work without the syrup in the tank. Not observing this recommendation can lead to serious damages in the pump.
