Tool carrying frame for tractor, comprises transverse tubes with side members, three point tractor connection and tool bearing side girders carried by bars which slide transversely in the tubes

摘要

Two parallel transverse tubes (1,6) are joined by side members (7) and the inboard tube is supported by three tractor connections (2,3). Tool carrying girders (8) are mounted on bars (9) which slide within the transverse tubes when an actuator (13) operates in response to feelers (10) and sensors (12). The height of the frame is detected by sensors (14) and any necessary adjustment is made at the tractor connection
