Tractor coupling

M x s < 0,2 T x i + Z x (d + i)

i = tractor wheelbase

d = distance from the front axis and the ballast

s = overhang from the rear axle of the

operating machine

T = mass of the tractor + operator (75kg)

Z = ballast mass M = sprayer mass

4.4TRACTOR COUPLING

The tractor must have 1”3/8 ASAE DIN 9611/A power-takeoff that runs at 550 rpm. It must have a 3-point elevator suitable for safely supporting the weight of the atomiser.

Check this by consulting the table of allowed fittings N° 14A-15A-16A (pages 37, 38, 39).

WARNING: make sure there are no persons or things near the atomiser before starting the machine and while you are using it.

4.4.1 THREE-POINT COUPLING

a)We recommend carefully checking that the tractor is suitable for supporting the weight of the fully loaded sprayer safely.

The total weight of the sprayer with all of its accessories and fittings is indicated on the nameplate in FIG. 2 and also (in the version with the maximum fittings allowed) in tables N° 14A-15A-16A (pages 37, 38, 39).

For verification use the formula shown here.

Non-observance can result in a very dangerous situation as the tractor will lose steering sensitivity and can tip over when driving uphill or over bumps.

b)Check the diameter of the elevator coupling pins. If necessary position the double diameter pins correctly; there are also appropriate adapter bushes available.

c)Adjust the length of the third point tie-rod correctly so the sprayer is perfectly vertical in normal working position.

d)Check for the presence of the safety pins that stop the arms of the tractor jumping off the connecting pins.

4.4.2 HYDRAULIC CONNECTION TO THE DISTRIBUTORS

Machines that need a hydraulic connection to drive the movements of the cannon are equipped with 1/2", “Push-Pull”, quick-fit male couplings. You can connect the pipes by simply pushing them in, making sure you:

-do so only with the engine turned off;

-lower any tools connected to the elevator of the tractor;

-carefully clean the two parts that will be coupled

Warning: the hydraulic cylinders used are the “Double Effect” type. Consult the use and maintenance manual of the tractor.
