4.7 Starting Settings

This section details the recommended start-

ing settings for the SL700. These settings

can then be used as a base for further adjust-

ment in order to get the optimum performace

from your machine.

Ensure all settings from the left and right hand

sides of the machine match each other.

4. Adjustment / Operation

4.6 Work Settings

In work the wing cylinders should be fully

extended. A simple pressurised hydraulic

circuit automatically sets itself as the wings

are unfolded.

Optimum performance has been found to be

achieved when the press roll rings have worn

away the painted finish leaving a smooth shiny

surface. When the press roll rings are new or

rusty, soil may tend to pick up on the surface

and blockage may occur, this will reduce when

the rings are shiny again.

The SL700 should be run with the chassis level

by extending the drawbar cylinder to the

necessary position and adding shims as

appropriate. In practice it is possible to use

the SL700 on ground conditions that are

unsuitable to achieve the desired effect, and

it is usually possible to operate without regular

blockage under such unsuitable conditions,

assuming that the axles are tight and rings

smooth. As such, especially under wet

conditions, it is advisable to check on the

cultivation effect of the SL700.

Generally a forward speed of 5-7 mph (8-11

kph) will achieve optimum results, maximising

inversion and burial. Speeds in excess of

those stated above will tend to give a

deterioration in the quality of the work. This

may be seen as a ridge and trough effect

across the work surface due to soil being

thrown too far by the leading discs, the rear

discs then are unable to turn enough soil back.

In normal operation the machine should be

carried between the rear roll and front depth

wheels with the lift circuit in float.

If using the machine without the front depth

wheels it should be hydraulically drawn onto

the drawbar shims. It is permissibleto operate

the lift circuit in float in order to allow the

implement to follow contours as the tractor

drawbar drops (eg. over the brow of a hill).

Drawbar Cylinder

The drawbar cylinder shim set-

tings are subject to the tractor

drawbar height. As such, the

shim settings shown above are

intended as a suggestion only.

The machine should be set to

run with the chassis level.
