4.12 Work Instructions

Driving speed

The Solo can be driven at speeds of up to 12

km/h.

This depends on the field conditions (type of

soil, surface trash, etc.).

Drive more slowly if the conditions are difficult

or a firmer finish is required.

Turning:

Before turning, the machine should

be eased out of work while driving.

Likewise, it should eased back into

work once the turn has been

completed.

4. Adjustment / Operation

4.11 Depth Control

Working depth can be set by mid or rear roll

and/or by transport wheels. Under normal

conditions the weight of the machine will be

carried on the roll and the drawbar of the

tractor, with the main lift wheels either fully up

or floating. Depth is set using the depth

control rod situated on the roll unit with shims

added and removed as appropriate. This is

achieved by raising the machine so that the

roll is clear of the ground and operating the

roll hydraulics until the wings just start to fold.

In this position it is possible for shims to be

added/removed from the depth control rod.

The roll can then be pressured back down and

the machine can continue to work. The front

to rear pitch of the machine should be

adjusted as appropriate to compensate for

changes in working depth by adjusting the

amount of shims on the drawbar cylinder.

Some conditions or finished effects may

dictate that depth control is carried out using

both the roll and the lift wheels.

With a Mid Roll / Rear Roll

Use roll depth adjuster/hydraulic cylinder to

set machine working depth - ensure wheels

are lifted clear of or just touching soil. Use

shims on drawbar cylinders to set chassis

pitch level. Machine can be run in float to

contour follow.

With the Transport Wheels

Use shims on lift cylinders to set machine

depth and shims on drawbar cylinders for

pitch. Balance the weight on wheels and roll

if they are to be used together for depth

control.

4.13 Parking the machine

In order to avoid damage as a result of

moisture, the machine should be parked, if

possible, indoors or under cover.

When manoeuvring the machine,

pay attention to your surroundings.

Ensure that nobody is in the

manoeuvring area (watch for

children!).

• Park the machine on level and solid ground.

• Raise the machine and remove shims from

the lift axle and drawbar cylinders.

• Lower the machine to the ground, ensuring

that it is stable.

When parking, ensure that no load

is carried by the Terra-Grip tines (if

fitted). This can lead to breakage

of the points.

• Remove the drawbar pin and drive forward

slowly until hitch is clear of tractor drawbar.

• Lower the drawbar to the ground.

• Switch off the tractor.

• Disconnect hydraulic lines from the tractor.
