Abstract
An arrangement for controlling a work machine which includes (i) a boom and (ii) a coupling mechanism secured to an end of the boom is disclosed. The arrangement includes a first control assembly having (i) a first gripping portion and (ii) a first actuator secured to the first gripping portion so that the first actuator can move relative to the first gripping portion. The first control assembly is configured to be operatively coupled to the boom and the coupling mechanism of the work machine such that (i) movement of the first gripping portion in (A) a first direction causes the boom to execute a first movement function, (B) a second direction causes the boom to execute a second movement function, (C) a third direction causes the coupling mechanism to move relative to the boom in a first direction, and (D) a fourth direction causes the coupling mechanism to move relative to the boom in a second direction and (ii) movement of the first actuator relative to the first gripping portion in (A) a first direction causes the boom to execute a third movement function and (B) a second direction causes the boom to execute a fourth movement function.
