Abstract

The table can be raised lowered and has crop lifters or similar devices which serve as sensors for the automatic control of height above soil of the table. The sensor unit is stirrup shaped and is rigidly fixed to the cutting table which also has sensors attached rigidly to a support integral with the cutter table, so that the sensor acts as a limiting sensor, deriving its information and therefore its switching function from the damped sensor with which it is in contact by means of a push button. The information is translated into electric impulses and thence into upward or downward movement of the cutting table.
