3.2 OPERATING MODE II: Laying down the PE-pipe
In addition to the pull-off method, the PE-pipe also can be laid down on the ground. This method is
mostly used in situations where heavy soil makes it impossible to pull the cart across the field or where
the field is longer than once the PE-pipe length. Moreover, the laying down method allows to use
smaller tractors because no pulling forces are applied on the pipe.
Drive into the field with the Smart RAIN taking into consideration the sprinkler's distance of throw.
*) W = distance of throw of the sprinkler
Carry out the next steps as already described.
3.2.1 FUNCTIONAL DESCRIPTIONOF THE MAIN COMPONENTS
3.2.1.1 MACHINE DRIVE – FULL-FLOW TURBINE
16
Lower the cart as described under Operating Mode I, item
"Lowering the Cart" and anchor it slightly. Now move the
machine across the field.
The full-flow turbine Ti 7-A is a drive turbine of specific design
with large cross sections and minimum pressure loss.
Therefore they are also suited for high retraction speeds at
very low flow rates. They provide the energy needed for the
PE-pipe retraction. The turbine speed is directly taken off the
impeller shaft and transmitted via a three-step V-belt drive to
the BAUER change-speed gearbox.
