Operating Instructions

The SIMBA Solo is an amalgamation of time

proven, successful Simba design

components brought together to form this

important development. The Solo has been

designed and produced in conjunction with

the Simba ECOtillage™ system to provide a

one pass mix with a fissured layer at disc

depth for through drainage and root access

to lower horizons. This enables rapid

drainage and access after rain, creating a

greater effective capacity for moisture

compared to ploughing for the same effective

total depth of cultivation.

In principle, the machine is a tandem disc with

trip reset Pro-Lift tines or Terra-Grip tines,

designed for low draft, high speed operations.

The addition of an integral roller ahead of the

rear gang, or a rear mounted roll, enables

more effective cultivation in one pass. The

leading set of disc blades cultivate the top

horizon, minimising clod formation and

reducing tine loadings and blockage. This

starts the ‘top down’ cultivation process,

retaining weathered tilth in the surface level

for stale seedbed purposes. The trip reset

tines follow the disc blades to shatter at depth

retaining the surface intact to work as an

ECOtillage

™ stale seedbed. This eliminates

the problem of ‘wet years’ in non-plough

based terms. The key to the Solo’s success

is the lower draft tine point and wing which

maintain shatter across the full width of

cultivation. The mid/rear roll or trailing press

then consolidates the surface, cracks any

clods and firms the soil profile before/after the

rear gang completes mixing to depth. The

corrugated top and shattered lower horizons

are left fully weatherproof to any conditions

between cultivation and drilling whilst retaining

moisture below the surface for rapid straw

breakdown and optimum establishment of the

next crop.

4.2 Solo Designations

Solo 380 ST R

123

1. This number refers to the working width

of the machine.

2. The ‘ST‘ stands for Shallow Tine. If a

machine is fitted with Terragrip tines it

is given this designation. If a machine

is fitted with hydraulic reset Pro-Lift tines

these letters will be absent from the

designation.

3. The ‘R‘ refers to the Rear roll format of

the machine. If no ‘R‘ is present in the

designation then the machine is set up

in the mid-roll format.

Examples:

Solo 380 ST - This is a 3.8m wide machine,

with Terragrip tines in the mid-

roll configuration.

Solo 330 R - This is a 3.3m wide machine,

with hydralic trip-reset tines in

the rear roll configuration.
