Hitching the machine

1313


Hitching the machine We strongly recommend that you observe the safety warnings given in the previous pages of this manual.

The category of the tractor 3-point linkage must match that of the implement.

To attach the harrow to the tractor, proceed as follows:> Line up the tractor with the harrow> Insert the lower links of the tractor's hydraulic linkage in the corresponding

mounting brackets on the implement, which should both be positioned at the same distance from the tractor.

> Secure the lower links with the pins and locking pins provided.

NOTE Attachment is made easier if the lower link stabilisers are adjusted soas to allow the lower links to move freely.On completion of the hitching operation, the stabilisers should beadjusted so as to limit oscillation (during implement transport, alloscillation must be completely eliminated).

> Insert the end of the top link of the tractor's hydraulic linkage in the upper mounting bracket of the harrow and secure it with the relative pins and locking pins.

> Adjust the length of the top link, bearing in mind that the drive shaft transmitting power from the tractor Pto to the harrow must be horizontal when the implement is in operation.

Mounting bracketfor Cat.2 linkage

NGH NGS


1414


NOTE In working position, the top link of the tractor's hydraulic linkageshould slope down towards the tractor (see next figure).

This configuration enables the implement to overcome obstacles andensure that the roller is loaded correctly. Incorrect adjustment (e.g. topand lower links parallel) will result in an excessive load on theimplement and the roller.

Tractor and implement combination: do not exceed the maximumpermitted weights!The combination of the mounted implement and tractor must notexceed the maximum permitted weight, i.e. the maximum permittedaxle loads and the load capacity of the tractor wheels. At least 20% ofthe tractor weight must be supported on the front axle of the tractor.

Connection of the drive shaft

Check the dimensions!Before connecting the drive shaft, check that its dimensions aresuitable for attachment to the tractor's Pto.If the drive shaft is too long, this could cause serious damage to thetransmissions of the tractor and the harrow, as well as to the shaft itself.If the drive shaft is too short, the two halves of the shaft could becomeseparated with a consequent risk of serious injury and damage.

To check the length of the drive shaft, proceed as follows:• Place the two halves of the drive shaft assembly (the half

connected to the tractor Pto and the half connected to the implement) side by side; the tractor Pto half and the implement half should be parallel; the angle can be adjusted by way of the top link of the hydraulic linkage.

• If the sliding distance of the shafts is less than 40mm, then both the halves will have to be shortened by a corresponding amount. Maintain the difference in length between the outer tube and the inner section.

• Always make sure that the maximum coverage of the sliding element is maintained. The coverage should be at least 1/3 during operation.

• With the harrow in the working position, the angle of the drive shaft should not exceed 20° (for example, at a working depth of 10 cm), while the maximum permitted angle is 25°.

Adjusting and replacing the scrapers

The disc roller is comprised of large diameter discs combined with aseries of shoes and blades mounted on an adjustable bar (43). Thebar can be adjusted for increments in the working depth of 25 mm. Adjustment is obtained by altering the position of the upper arm (44)that connects the bar to the frame of the roller.Mounted on the arm there is a spring that presses the shoes againstthe roller and the rear blades against the soil.

Adjusting the position of the blades and scrapers:> Remove the locking pin securing the adjustment pin (45)> Position the adjustment pin in accordance with the following indications:• Insert the pin in position (46) for heavy soil and rough ground: the

rear blades and the lower edges of the disc will be at the same height.

• Insert the pin in position (47) for medium heavy soil: the blades will be positioned higher than the lower edges of the discs.

• Insert the pin in position (48) for light soil: the blades will work by gravity alone.

• Insert the pin in position (49) to disengage the blades.> Replace the locking pin to secure the adjustment pin.

Further blade adjustments may be made by way of the lock nuts (50).As the blades become worn or to increase the spring pressure,
