Assembly

In most instances QUIVOGNE Disc Harrows will be fully assembled prior to

delivery to the customer. It may, however, be necessary to deliver the larger

working width machines with the disc sections left loose for final assembly at

point of delivery and in these cases full instructions are provided with the

relative machines regarding final assembly procedure.

Power Supply

The MasterDisc requires a 12volt-power supply and is fitted with a plug to fit

a cigarette lighter socket.

Assembly of the Hydraulic Pipes

Use P.T.F.E tape or similar material on the cylinder connections to avoid the

possibility of oil leakages.

Avoid sharp bends on the pipes and ensure that all pipes are fixed clear of any

moving parts.

Controls

Hydraulic services

The standard MasterDisc requires two hydraulic services. One lifts and lowers

the machine, the other controls all remaining functions in conjunction with the

electronic spool block.

Depth Control

Lift and lower the machine using the tractors external hydraulics. Set working

depth with the stop mounted on the offside lifting cylinder.

Electro Hydraulic Controls

• Button LH I controls rear gangs

• Button LH II controls front to rear levelling

• Button RH I controls front gangs

• Button RH II is not used.

Front To Rear Levelling

Push button RH II and then operate hydraulics. In work the main chassis

should be parallel to the ground.

Gang Clamps

Whether in work or transport gangs should always be clamped up tight. Only

release the gang clamps to move the gangs.

To operate the clamps simply operate hydraulics without pushing any button.

Front Gangs

To move the front gangs push button RH I and then operate hydraulics.

Rear Gangs

To move rear gangs push button LH I and then operate Hydraulics.

When setting into work we suggest that the angle of the discs is initially set so

e front gangs are more aggressive than the rear.

From this position “OPENING” the discs (moving the front discs further

forward and the rear discs further back) will INCREASE the cutting action

and “CLOSING

” the discs by moving in the opposite direction will reduce the

utting action.

If the discs leave a ridge or a d

epression in the middle , carry out the

llowing minor adjustments:

) To remove a ridge

PEN up the front set of discs

) To remove a depression

CLOSE up the front set of discs

Maintenance

Tighten All Bolts & Check Regularly

It is important that all bolts are checked for tightness after each days work

(8 hours) and again at the end of the season before putting into storage.

Regularly check that the disc gang pivot bolt to the main frame is tight.

The nut is retained in position by a grub screw which must be loosened

before tightening the nut. Ensure that the grub screw is retightened after

adjustment of the pivot bolt has been made.

Each gang of discs is fitted with a shaft nut and locking plate.

Regularly check these shaft nuts and make sure they are kept very tight-

use the special spanner supplied with the machine. This spanner also fits

the pivot bolt nut.

Lubrication

Grease with:SHELL RETINAX A

Or equivalent product

TOTAL MULTIS EP

Grease all nipples before starting work with the machine and every 8

hours thereafter.

It is important not to over grease the shaft bearing assemblies and ‘blow

the seals’. These bearing assemblies are triple sealed conical bearings and

as such do not need excess greasing. Excess greasing of these assemblies,

and the resulting ‘blowing of the seals’ will encourage dirt into the

housing. This will eventually result in the failure and collapse of the

bearing unit.

The undercarriage linkage assembly requires the most frequent amounts

of greasing.
