Apparatus for controlling output from engine on crawler type tractor
 At the time of starting movement as well as at the time when a crawler type tractor, e.g., a bulldozer for performing a dosing operation and a ripping operation is held in a three-point grounding state, an output from an engine (10) is automatically reduced further from a normal cut-off state, whereby an operator is not required to depress a deceleration pedal (13). Consequently, a burden to be borne by him can be reduced substantially.
